<title>使用Nexmo发送中文短信</title>
<url>/2016/07/18/send-chinese-sms-using-nexmo/</url>
<content><![CDATA[<p>最近公司的项目要发送短信通知，因为用户都是国际用户，因此国际短信是必不可少的，一开始打算选择国内的【云片】平台，但是签名不能是全英文有些尴尬，最终选择了【Nexmo】。</p>
<p>Nexmo发送短信的<a href="https://docs.nexmo.com/messaging/sms-api" target="_blank" rel="noopener">API</a>还是非常简单的，一些语言也给出了详细的使用例子。这里copy一下nodejs的例子。</p>
<p>需要注意的是，如果发送的内容带有中文等字符，需要将<code>type</code>设置为<code>unicode</code>，不然的话收到的短信中这些字符会全部为问号。</p>
<a id="more"></a>
<pre><code class="js"><span class="keyword">var</span> https = <span class="built_in">require</span>(<span class="string">'https'</span>);
<span class="keyword">var</span> data = <span class="built_in">JSON</span>.stringify({

<title>【翻译】Nodejs - Breaking changes between v5 and v6</title>
<url>/2016/05/18/nodejs-breaking-changes-between-v5-and-v6/</url>
<content><![CDATA[<p>英语水平比较渣，如果有翻译不对的地方请指出，谢谢。<br>原文地址：<a href="https://github.com/nodejs/wiki-archive/blob/master/Breaking-changes-between-v5-and-v6.md" target="_blank" rel="noopener">Nodejs - Breaking changes between v5 and v6</a></p>
<hr>
<p>查看之前的改动日志，请查看<a href="https://github.com/nodejs/node/wiki/Breaking-changes-between-v4-and-v5" target="_blank" rel="noopener">v4 to v5</a>页面。</p>
<p>89个提交被标记为<code>semver-major</code>。</p>
<a id="more"></a>
<p><strong>注意</strong>：<code>#</code> 与 <code>.prototype.</code> 同意，表示该类的实例的属性是可用的。<br>例如：<code>Object#toString()</code> 等同于 <code>Object.prototype.toString()</code>。</p>

<ul>
<li>弃用<code>new Buffer()</code>并由一些列新增的<a href="https://nodejs.org/dist/latest-v6.x/docs/api/buffer.html#buffer_buffer_from_buffer_alloc_and_buffer_allocunsafe" target="_blank" rel="noopener">Buffer API: <code>Buffer.from()</code>，<code>Buffer.alloc()</code>，<code>Buffer.allocUnsafe()</code></a>替代。<ul>
<li>Refs： <a href="https://github.com/nodejs/node/commit/85ab4a5f12" target="_blank" rel="noopener"><code>85ab4a5f12</code></a>，<a href="https://github.com/nodejs/node/pull/4682" target="_blank" rel="noopener">#4682</a></li>
</ul>
</li>
<li>移除之前弃用的<code>Buffer#write(string, encoding, offset, length)</code><ul>
<li><a href="https://nodejs.org/dist/latest-v6.x/docs/api/buffer.html#buffer_buf_write_string_offset_length_encoding" target="_blank" rel="noopener"><code>Buffer#write()</code></a>保留其他调用方式，如<code>Buffer#write(string[, encoding])</code>。</li>
<li>Refs: <a href="https://github.com/nodejs/node/commit/2c55cc2d2c" target="_blank" rel="noopener"><code>2c55cc2d2c</code></a>, <a href="https://github.com/nodejs/node/pull/5048" target="_blank" rel="noopener">#5048</a></li>
</ul>
</li>
<li>移除之前弃用的<code>Buffer#{get|set}</code>方法。<ul>
<li><code>Buffer#get(index)</code>由<code>buffer[index]</code>替代。</li>
<li><code>Buffer#set(index, value)</code>由<code>buffer[index] = value</code>替代。</li>
<li>Refs: <a href="https://github.com/nodejs/node/commit/101bca988c" target="_blank" rel="noopener"><code>101bca988c</code></a>, <a href="https://github.com/nodejs/node/pull/4594" target="_blank" rel="noopener">#4594</a></li>
</ul>
</li>
<li><code>new Buffer(length, encoding)</code>现在会抛出异常。<ul>
<li>如果传入的<code>length</code>参数是数字的话没有什么影响（译者注：个人认为这里应该是传入参数是string类型没有影响，推荐详细阅读PR），这个改动用来指出一种潜在的安全问题。</li>
<li>Refs: <a href="https://github.com/nodejs/node/commit/3b27dd5ce1" target="_blank" rel="noopener"><code>3b27dd5ce1</code></a>, <a href="https://github.com/nodejs/node/pull/4514" target="_blank" rel="noopener">#4514</a></li>
</ul>

<p>Save installed package(s) to package.json.</p>
<p>Sometimes, I install a npm package but forgot to add <code>--save</code> or <code>--save-dev</code>. What should I do if I want to save this package to <code>package.json</code>?</p>
<p>I try to google it but no answer found. So, I write <code>pkg-save</code> to do it.</p>

<p>简单起见，404和error handler就不写了。<br><code>node src/app.js</code>跑起来，浏览器打开<a href="http://localhost:3000" target="_blank" rel="noopener">http://localhost:3000</a>，可以看到页面中显示<code>Hello World!</code>了。</p>
<p><a id="babel"></a></p>
<h2 id="Babel"><a href="#Babel" class="headerlink" title="Babel"></a>Babel</h2><p>babel升级到6.x之后，需要明确指定转换，我们使用预设的es2015。</p>

<h3 id="使用es6语法编写代码"><a href="#使用es6语法编写代码" class="headerlink" title="使用es6语法编写代码"></a>使用es6语法编写代码</h3><p>我们现在将之前写过的<code>src/app.js</code>修改为es6语法</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">// src/app.js</span><br><span class="line"></span><br><span class="line">import express, { Router } from 'express';</span><br><span class="line">import bodyParser from 'body-parser';</span><br><span class="line"></span><br><span class="line">let app = express();</span><br><span class="line">let router = Router();</span><br><span class="line"></span><br><span class="line">app.use(bodyParser.json());</span><br><span class="line">app.use(bodyParser.urlencoded({ extended: true }));</span><br><span class="line">app.use(cookieParser());</span><br><span class="line"></span><br><span class="line">router.get('/', (req, res, next) => {</span><br><span class="line"> res.end('Hello World!');</span><br><span class="line">});</span><br><span class="line">app.use('/', router);</span><br><span class="line"></span><br><span class="line">app.listen(3000, () => {</span><br><span class="line"> console.log('server listening at port 3000...');</span><br><span class="line">});</span><br></pre></td></tr></table></figure>

<h3 id="使用bebel转换"><a href="#使用bebel转换" class="headerlink" title="使用bebel转换"></a>使用bebel转换</h3><p>将代码修改为es6语法之后，就可以使用babel进行转换了。<br>使用命令<code>babel src -d lib</code><br>可以看到控制台中显示：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">src/app.js -> lib/app.js</span><br></pre></td></tr></table></figure>
<p>之后还是运行一下看看效果，浏览器打开<a href="http://localhost:3000" target="_blank" rel="noopener">http://localhost:3000</a>，我们和熟悉的<code>Hello World</code>又见面啦。</p>
<p><a id="gulp"></a></p>
<h2 id="Gulp"><a href="#Gulp" class="headerlink" title="Gulp"></a>Gulp</h2><p>每次修改完代码都要重新用babel转换一次是不是很麻烦？别怕，我们有gulp。</p>
<p><a id="gulp-install"></a></p>

<p><a id="gulpfile"></a></p>
<h3 id="编写gulpfile"><a href="#编写gulpfile" class="headerlink" title="编写gulpfile"></a>编写gulpfile</h3><p>在根目录新建一个gulpfile.babel.js文件。<br>gulp原生并不支持es6语法，但是我们可以告诉gulp使用babel将gulpfile转换为es5，方法就是将gulpfile命名为gulpfile.babel.js</p>
<p><a id="gulpfile-default"></a></p>
<h4 id="一个简单的gulpfile"><a href="#一个简单的gulpfile" class="headerlink" title="一个简单的gulpfile"></a>一个简单的gulpfile</h4><p>我们先写一个简单的gulpfile测试一下gulp是否能够正常工作。</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">import gulp from 'gulp';</span><br><span class="line">import babel from 'gulp-babel';</span><br><span class="line"></span><br><span class="line">gulp.task('default', () => {</span><br><span class="line"> return gulp.src('src/**/*.js')</span><br><span class="line"> .pipe(babel())</span><br><span class="line"> .pipe(gulp.dest('lib'));</span><br><span class="line">});</span><br></pre></td></tr></table></figure>
<p>控制台执行<code>gulp</code>，可以看到：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">[13:00:35] Requiring external module babel-register</span><br><span class="line">[13:00:36] Using gulpfile /path/to/file/gulpfile.babel.js</span><br><span class="line">[13:00:36] Starting 'default'...</span><br><span class="line">[13:00:36] Finished 'default' after 191 ms</span><br></pre></td></tr></table></figure>
<p>然后lib文件夹下就生成了转换后的文件了。</p>
<p><a id="gulpfile-watch"></a></p>
<h4 id="能够监听文件更改的gulpfile"><a href="#能够监听文件更改的gulpfile" class="headerlink" title="能够监听文件更改的gulpfile"></a>能够监听文件更改的gulpfile</h4><p>虽然上面的gulpfile能够将使用了，但是还是跟之前直接用babel一样，每次都要gulp一下，下面我们就来写一个能够监听文件的gulpfile。当文件被修改之后，自动将文件转换。<br>这里使用<code>gulp-watch</code>监听文件更改。<br><code>npm install --save-dev gulp-watch</code></p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">import gulp from 'gulp';</span><br><span class="line">import watch from 'gulp-watch';</span><br><span class="line">import babel from 'gulp-babel';</span><br><span class="line"></span><br><span class="line">gulp.task('transform', () => {</span><br><span class="line"> return gulp.src('src/**/*.js')</span><br><span class="line"> .pipe(babel())</span><br><span class="line"> .pipe(gulp.dest('lib'));</span><br><span class="line">});</span><br><span class="line"></span><br><span class="line">gulp.task('watch', () => {</span><br><span class="line"> return gulp.src('src/**/*.js')</span><br><span class="line"> .pipe(watch('src/**/*.js', {</span><br><span class="line"> verbose: true</span><br><span class="line"> }))</span><br><span class="line"> .pipe(babel())</span><br><span class="line"> .pipe(gulp.dest('lib'));</span><br><span class="line">});</span><br><span class="line"></span><br><span class="line">gulp.task('default', () => {</span><br><span class="line"> gulp.start('transform');</span><br><span class="line">});</span><br></pre></td></tr></table></figure>
<p>控制台执行<code>gulp watch</code></p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">[14:11:46] Requiring external module babel-register</span><br><span class="line">[14:11:47] Using gulpfile /file/to/path/gulpfile.babel.js</span><br><span class="line">[14:11:47] Starting 'watch'...</span><br></pre></td></tr></table></figure>
<p>然后修改app.js并保存，可以看到控制台中多了一行信息</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">[14:13:20] app.js was changed</span><br></pre></td></tr></table></figure>

<title>Sails+wechat(解决sails无法处理微信消息)</title>
<url>/2015/09/18/sails-wechat/</url>
<content><![CDATA[<p><a href="https://github.com/balderdashy/sails" target="_blank" rel="noopener">sails</a>框架使用<a href="https://github.com/node-webot/wechat" target="_blank" rel="noopener">wechat</a> 的时候能够通过验证却不能处理微信消息，原因是sails默认的bodyPaser(<a href="https://github.com/balderdashy/skipper" target="_blank" rel="noopener">skipper</a>)不支持’text/xml’形式的请求(<a href="https://github.com/balderdashy/sails/issues/2714" target="_blank" rel="noopener">sails issues#2714</a>)</p>
<p>YunnuY同学使用<a href="https://www.npmjs.com/package/express-xml-bodyparser" target="_blank" rel="noopener">express-xml-bodyparser</a>和<a href="https://www.npmjs.com/package/body-parser" target="_blank" rel="noopener">body-parser</a>覆盖了sails默认的bodyParser</p>
<p><a href="https://github.com/YunnuY/sweat/blob/master/config/http.js" target="_blank" rel="noopener">https://github.com/YunnuY/sweat/blob/master/config/http.js</a></p>
<p>由于body-paser后来更新，所以这里的代码要稍微修改一下,将<code>var bodyParser = require('body-parser')();</code>修改为<code>var bodyParser = require('body-parser')().json();</code></p>
<hr>
<p>但是公司的项目中还有包含文件的请求，此时body-paser就不能满足需求了，因此还是要重新使用sails默认的skipper，代码如下：</p>
<pre><code>bodyParser: function() {
var xmlParser = require('express-xml-bodyparser')();
var skipper = require('skipper')();
return function(req, res, next) {
if (req.headers &amp;&amp; (req.headers['content-type'] == 'text/xml' || req.headers['content-type'] == 'application/xml')) {
return xmlParser(req, res, next);
}
return skipper(req, res, next);
};
}</code></pre><p>目前程序能够正常处理微信消息和常规请求，如果出现问题我会及时更新。</p>

<title>JDBC事务处理</title>
<url>/2014/12/30/jdbc-transaction/</url>
<content><![CDATA[<p>在JDBC中，事务操作默认是自动提交。也就是说，一条对数据库的更新表达式代表一项事务操作。操作成功后，系统将自动调用<code>commit()</code>来提交，否则将调用<code>rollback()</code>来回退。<br>可以通过调用<code>setAutoCommit(false)</code>来禁止自动提交。之后就可以把多个数据库操作的表达式作为一个事务，在操作完成后调用<code>commit()</code>来进行整体提交。<br>倘若其中一个表达式操作失败，都不会执行到<code>commit()</code>，并且将产生响应的异常。此时就可以在异常捕获时调用<code>rollback()</code>进行回退。<br>这样做可以保持多次更新操作后，相关数据的一致性。</p>

<title>CentOS7编译安装git并配置使用github</title>
<url>/2014/12/26/centos7-git-github/</url>
<content><![CDATA[<h2 id="一、编译安装git"><a href="#一、编译安装git" class="headerlink" title="一、编译安装git"></a>一、编译安装git</h2><p>CentOS7默认安装的git版本为1.8.3.1，而git官方的版本已经到2.2.0了，所以选择下载源码编译安装git</p>
<h3 id="1-clone-github上的git源码"><a href="#1-clone-github上的git源码" class="headerlink" title="1.clone github上的git源码"></a>1.clone github上的git源码</h3><p><code>$ git clone https://github.com/git/git.git</code></p>
<h3 id="2-进入git目录进行配置及安装"><a href="#2-进入git目录进行配置及安装" class="headerlink" title="2.进入git目录进行配置及安装"></a>2.进入git目录进行配置及安装</h3><figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ cd git</span><br><span class="line">$ autoconf</span><br><span class="line">$ ./configure</span><br><span class="line">$ make</span><br><span class="line">$ make install</span><br></pre></td></tr></table></figure>
<p>期间可能会提示缺少文件，是因为git的依赖包没有安装，缺什么装什么就好，或者直接<br><code>yum -y install curl curl-devel zlib-devel openssl-deve perl perl-devel cpio expat-devel gettext-deve</code></p>
<h3 id="3-查看版本"><a href="#3-查看版本" class="headerlink" title="3.查看版本"></a>3.查看版本</h3><figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ git --version</span><br><span class="line">git version 1.8.3.1</span><br></pre></td></tr></table></figure>
<p>竟然还是原来的版本而不是最新安装的2.2.0，那只能先把旧版本卸载了</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ rpm -q git</span><br><span class="line">git-1.8.3.1-4.el7.x86_64</span><br><span class="line">$ sudo rpm -e --nodeps git-1.8.3.1-4.el7.x86_64</span><br></pre></td></tr></table></figure>
<p>然后执行<br><code>sudo ln -s /usr/local/bin/* /usr/bin/</code><br>再次查看git版本</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ git --version</span><br><span class="line">git version 2.2.0.GIT</span><br></pre></td></tr></table></figure>
<p>git版本已经是我们新安装的2.2.0了</p>
<h3 id="4-设置自己的用户名和邮箱"><a href="#4-设置自己的用户名和邮箱" class="headerlink" title="4.设置自己的用户名和邮箱"></a>4.设置自己的用户名和邮箱</h3><p>命令行输入：（引号加不加无所谓）</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ git config --global user.name "Your Name"</span><br><span class="line">$ git config --global user.email "[email protected]"</span><br></pre></td></tr></table></figure>
<h3 id="5-在本地创建仓库并初始化"><a href="#5-在本地创建仓库并初始化" class="headerlink" title="5.在本地创建仓库并初始化"></a>5.在本地创建仓库并初始化</h3><figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ mkdir test</span><br><span class="line">$ cd test</span><br><span class="line">$ git init</span><br></pre></td></tr></table></figure>
<p>初始化空的 Git 版本库于 <code>/home/username/github/test/.git/</code><br>至此git安装完成</p>
<h2 id="二、使用github"><a href="#二、使用github" class="headerlink" title="二、使用github"></a>二、使用github</h2><p>1.注册github账号</p>
<p>我这里创建了一个账号：<code>SinalVee</code>，并创建了一个<code>Test</code>仓库用于测试</p>
<p>2.用ssh-kengen生成公钥</p>
<p><code>$ ssh-keygen -t rsa -C [email protected]</code><br><a href="mailto:[email protected]">[email protected]</a>为你的邮箱地址</p>
<p>设定存放目录和密码后在github设置中找到SSH Keys，选择Add SSH Key，设置名称并把<code>*/.ssh/id_rsa.pub</code>的文件内容粘贴进去</p>
<p>3.测试是否成功</p>
<p><code>$ ssh -T [email protected]</code><br>出现下面的信息并提示验证私钥则成功，输入密码解锁私钥</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">The authenticity of host 'github.com (192.30.252.130)' can't be established.</span><br><span class="line">RSA key fingerprint is 16:27:ac:axxxxxxxxxxxxxxxxx:df:a6:48.</span><br><span class="line">Are you sure you want to continue connecting (yes/no)? yes</span><br><span class="line">Warning: Permanently added 'github.com,192.30.252.130' (RSA) to the list of known hosts.</span><br><span class="line">Hi SinalVee! You've successfully authenticated, but GitHub does not provide shell access.</span><br></pre></td></tr></table></figure>
<p>在本地任意目录新建同步文件夹</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ mkdir github</span><br><span class="line">$ cd github</span><br><span class="line">$ git clone [email protected]:SinalVee/Test（此处SinalVee为用户名，Test是你在github上创建的仓库）</span><br></pre></td></tr></table></figure>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">正克隆到 'Test'...</span><br><span class="line">Warning: Permanently added the RSA host key for IP address '192.30.252.131' to the list of known hosts.</span><br><span class="line">remote: Counting objects: 6, done.</span><br><span class="line">remote: Total 6 (delta 0), reused 0 (delta 0)</span><br><span class="line">接收对象中: 100% (6/6), 完成.</span><br><span class="line">检查连接... 完成。</span><br></pre></td></tr></table></figure>
<p>因为我很久之前就创建了这个Test仓库并测试过，所以这里共有6个objects（一共两个文件，之所以这里是6是因为Git跟踪并管理的是修改，而非文件）。</p>
<p>接下来测试以下上传</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">$ cd Test/</span><br><span class="line">$ ls</span><br><span class="line">README.md test.txt</span><br><span class="line">$ touch hello.txt</span><br><span class="line">$ vim hello.txt</span><br><span class="line">你好，这是一个测试文件。</span><br><span class="line">$ ls</span><br><span class="line">hello.txt README.md test.txt</span><br><span class="line">$ git add hello.txt</span><br><span class="line">$ git commit -m "add file hello.txt"</span><br><span class="line">[master 0e4004c] add file hello.txt</span><br><span class="line"> 1 file changed, 1 insertion(+)</span><br><span class="line"> create mode 100644 hello.txt</span><br><span class="line">$ git push</span><br><span class="line">对象计数中: 3, 完成.</span><br><span class="line">Delta compression using up to 4 threads.</span><br><span class="line">压缩对象中: 100% (2/2), 完成.</span><br><span class="line">写入对象中: 100% (3/3), 354 bytes | 0 bytes/s, 完成.</span><br><span class="line">Total 3 (delta 0), reused 0 (delta 0)</span><br><span class="line">To [email protected]:sinalvee/Test</span><br><span class="line"> 984cabc..0e4004c master -> master</span><br></pre></td></tr></table></figure>
<p>在github的网页上刷新一下仓库，发现hello.txt已经上传成功了，至此我们的github已经配置成功，并可以使用了。</p>
<p>github的使用这里不多赘述了。</p>

<title>Maven仓库中添加Oracle JDBC驱动</title>
<url>/2014/12/18/maven-oracle-jdbc-driver/</url>
<content><![CDATA[<p>原文地址：<a href="http://maosheng.iteye.com/blog/2001615" target="_blank" rel="noopener">http://maosheng.iteye.com/blog/2001615</a></p>
<p>由于Oracle授权问题，Maven不提供Oracle JDBC driver，为了在Maven项目中应用Oracle JDBC driver,必须手动添加到本地仓库。</p>
<h2 id="一-获得Oracle-JDBC-Driver"><a href="#一-获得Oracle-JDBC-Driver" class="headerlink" title="一.获得Oracle JDBC Driver"></a>一.获得Oracle JDBC Driver</h2><p>1.通过Oracle官方网站下载相应版本：<a href="http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html" target="_blank" rel="noopener">http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html</a></p>
<p>2.通过Oracle的安装目录获得，位置在“{ORACLE_HOME}jdbclibojdbc14.jar”</p>
<h2 id="二-手动安装到本地仓库"><a href="#二-手动安装到本地仓库" class="headerlink" title="二.手动安装到本地仓库"></a>二.手动安装到本地仓库</h2><p>命令如下：</p>
<figure class="highlight plain"><table><tr><td class="code"><pre><span class="line">mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0.1.0 -Dpackaging=jar -Dfile=D:ojdbc14.jar</span><br></pre></td></tr></table></figure>
<h2 id="三-在pom-xml文件中添加引用"><a href="#三-在pom-xml文件中添加引用" class="headerlink" title="三.在pom.xml文件中添加引用"></a>三.在pom.xml文件中添加引用</h2><figure class="highlight xml"><table><tr><td class="code"><pre><span class="line"><span class="tag"><<span class="name">dependency</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">groupId</span>></span>com.oracle<span class="tag"></<span class="name">groupId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">artifactId</span>></span>ojdbc14<span class="tag"></<span class="name">artifactId</span>></span></span><br><span class="line"> <span class="tag"><<span class="name">version</span>></span>10.2.0.1.0<span class="tag"></<span class="name">version</span>></span></span><br><span class="line"><span class="tag"></<span class="name">dependency</span>></span></span><br></pre></td></tr></table></figure>
<p>之后就可以正常引用了。</p>
