The custom plug-in returns the result garbled

[griffenliu]

code:

function _M.access(conf, ctx)
    ...
    log.warn(">>>>>>>>>>>>>>>>>>", data)
    local accept_type = ngx.req.get_headers()["Accept"]
    if str_contains(accept_type, "text/html") then
        return 200, data
    else
        return 200, decode(data)
    end
end

The data comes from the cache

log:

2020/05/09 10:55:59 [warn] 23640#0: *812 [lua] dfy-cache-plugin.lua:380: phase_fun(): >>>>>>>>>>>>>>>>>>{"data":"测试服务器8001"}

result:

I think the reason is that the encoding is not configured in nginx.conf. Can we add utf-8 encoding into it or specify the encoding through configuration?

I think the reason is that the encoding is not configured in nginx.conf.

can you show a example? I don't konw how to add utf-8 encoding in nginx.conf.

[griffenliu]

http {
include mime.types;
default_type text/html;
charset utf8;
}

Can I modify APISIX Nginx template to solve this problem

[moonming]

sure, you can modify `bin/apisix` to fix it. And please add test cases for it. Thanks, Ming Wen Twitter: _WenMing xxm404 <[email protected]> 于2020年5月12日周二 下午5:55写道：

ok please assign this issue to me.

Add charset utf-8; to APISIX Nginx template

Modify example-plugin to test

restart apisix and execute curl -i 127.0.0.1:9080/api/bench/testSimple It still garbled

Hi @griffenliu can you give me a minimal reproducible example, I can not reproduce this problem
In my test, the response normally

my test code

function _M.access(conf, ctx)
    -- core.log.warn("plugin access phase, conf : ", core.json.encode(conf))
    -- return 200, core.json.decode(data)
    local redis = redis_new()
    local ok, err = redis:connect('127.0.0.1', 6379)
    if not ok then
        return false, err
    end
    local data = redis:get('data')
    core.log.warn(">>>>>>>>>>>>>>>", data)
    return 200, core.json.decode(data)
end

sorry, I'm late. There is no problem with your example, which is the same as mine. The encoding was normal when I used curl to test, but it was garbled when I used the browser.

Using the browser response results below, you can see the difference between a correct response and an error response:

＃ this is garbled response
Connection: keep-alive
Content-Type: text/plain
Date: Mon, 18 May 2020 09:53:34 GMT
Server: APISIX web server
Transfer-Encoding: chunked

# this is normal response,  Content-Type with encoding: charset=utf8.
Connection: keep-alive
Content-Type: text/plain; charset=utf8
Date: Mon, 18 May 2020 09:55:06 GMT
