需求：接口通过nginx转发服务器，接收不到数据，但是测试环境是好的；
环境：CentOS 6.5 64bit
nginx版本：1.12.2
配置方法：
[root@localhost nginx]# vim conf/nginx.conf
参考nginx官网说明：http://nginx.org/en/docs/http/ngx_http_upstream_module.html
For HTTP, the proxy_http_version directive should be set to “1.1” and the “Connection” header field should be cleared:
upstream http_backend {
server 127.0.0.1:8080;
keepalive 16;
}
server {
...
location /http/ {
proxy_pass http://http_backend;
proxy_http_version 1.1;
proxy_set_header Connection "";
...
}
}
