Nginx 内部调用另一个请求并返回该请求数据

Question

我正在使用 nginx 和 lua 来解析我的 rest api (https://openresty-reference.readthedocs.io/en/latest/Lua_Nginx_API/) 。我试图在我的 rest 调用中内部调用另一个 api，它是一个不同的服务器并返回该响应。但它总是得到空洞的回应。以下是我的配置，我请求 /student 任何帮助都是非常可观的

location /student {
    content_by_lua '
    local str = "test"
    local res = ngx.location.capture("/detail",{method = ngx.HTTP_POST, body = str})
    ngx.say(str)
    ';
}
location /detail {
    set $target '104.28.17.1/post';
    set $pass 'Basic Y2l28=';
    lua_need_request_body on;
    content_by_lua '
    proxy_set_header          Host            $host;
    proxy_set_header          X-Real-IP       $remote_addr;
    proxy_set_header          X-Forwarded-For $proxy_add_x_forwarded_for;
    #access_by_lua '
    proxy_set_header Authorization $pass;
    proxy_set_header Content-Type 'application/x-www-form-urlencoded';
    proxy_set_header Accept '*/*';
    proxy_set_header Connection 'keep-alive';
    proxy_pass http://$target;
}

尝试将您的位置/学生更改为

location /student {
    content_by_lua '
    local str = "test"
    local res = ngx.location.capture("/detail",{method = ngx.HTTP_POST, body = str})
    ngx.status = 200
    ngx.say(str)
    ngx.exit(ngx.HTTP_OK)
    ';
}
