情况二解决办法修改完，我们需要重新加载php-fpm和nginx的配置，然后再进行测试。之后就没有发现“504 Gateway Time-out”错误，效果也还是不错的！

1、request\_time

官网描述：request processing time in seconds with a milliseconds resolution; time elapsed between the first bytes were read from the client and the log write after the last bytes were sent to the client 。

指的就是从接受用户请求的第一个字节到发送完响应数据的时间，即包括接收请求数据时间、程序响应时间、输出响应数据时间。

2、upstream\_response\_time

官网描述：keeps times of responses obtained from upstream servers; times are kept in seconds with a milliseconds resolution. Several response times are separated by commas and colons like addresses in the $upstream\_addr variable

是指从Nginx向后端(php-cgi)建立连接开始到接受完数据然后关闭连接为止的时间。

从上面的描述可以看出，$request\_time肯定比$upstream\_response\_time值大，特别是使用POST方式传递参数时，因为Nginx会把request body缓存住，接受完毕后才会把数据一起发给后端。所以如果用户网络较差，或者传递数据较大时，$request\_time会比$upstream\_response\_time大很多。

所以如果使用nginx的accesslog查看php程序中哪些接口比较慢的话，记得在log\_format中加入$upstream\_response\_time
