C#项目测试

参考地址 https://www.cnblogs.com/linezero/p/grpc.html

1.新建项目 2.添加引用

Install-Package Grpc
Install-Package Google.Protobuf
Install-Package Grpc.Tools

3.生成c#代码文件

packages\Grpc.Tools.1.12.0\tools\windows_x86\protoc.exe -IgRPCDemo --csharp_out gRPCDemo  gRPCDemo\helloworld.proto --grpc_out gRPCDemo --plugin=protoc-gen-grpc=packages\Grpc.Tools.1.12.0\tools\windows_x86\grpc_csharp_plugin.exe
packages\Grpc.Tools.1.12.0\tools\windows_x86\protoc.exe -IgRPCDemo --csharp_out gRPCDemo  gRPCDemo\cc.proto --grpc_out gRPCDemo --plugin=protoc-gen-grpc=packages\Grpc.Tools.1.12.0\tools\windows_x86\grpc_csharp_plugin.exe

4.编写测试用例,见源码

Go项目测试

1.生成go代码文件

protoc -I helloworld/ helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
protoc -I helloworld/ helloworld/cc.proto --go_out=plugins=grpc:helloworld

2.编写测试用例,见源码

使用openssl生成证书及密钥

1.在Windows上开发请安装 OpenSSL对应版本并将openssl.exe所在路径添加到环境变量中。

2.创建执行文件Generator.bat

@echo off
set OPENSSL_CONF=c:\OpenSSL-Win64\bin\openssl.cfg   

echo Generate CA key:
openssl genrsa -passout pass:1111 -des3 -out ca.key 4096

echo Generate CA certificate:
openssl req -passin pass:1111 -new -x509 -days 365 -key ca.key -out ca.crt -subj  "/C=US/ST=CA/L=Cupertino/O=YourCompany/OU=YourApp/CN=MyRootCA"

echo Generate server key:
openssl genrsa -passout pass:1111 -des3 -out server.key 4096

echo Generate server signing request:
openssl req -passin pass:1111 -new -key server.key -out server.csr -subj  "/C=US/ST=CA/L=Cupertino/O=YourCompany/OU=YourApp/CN=kekyk"

echo Self-sign server certificate:
openssl x509 -req -passin pass:1111 -days 365 -in server.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out server.crt

echo Remove passphrase from server key:
openssl rsa -passin pass:1111 -in server.key -out server.key

echo Generate client key
openssl genrsa -passout pass:1111 -des3 -out client.key 4096

echo Generate client signing request:
openssl req -passin pass:1111 -new -key client.key -out client.csr -subj  "/C=US/ST=CA/L=Cupertino/O=YourCompany/OU=YourApp/CN=client"

echo Self-sign client certificate:
openssl x509 -passin pass:1111 -req -days 365 -in client.csr -CA ca.crt -CAkey ca.key -set_serial 01 -out client.crt

echo Remove passphrase from client key:
openssl rsa -passin pass:1111 -in client.key -out client.key
