问题描述

1、程序回调接口结果404
2、使用postman等工具直接调用正常

10.171.81.1 - - [24/Apr/2022:10:50:19 +0800] "POST /xxx/overtime HTTP/1.0" 401 7809 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36" "----"
10.171.81.1 - - [24/Apr/2022:10:52:14 +0800] "POST /xxx/overtime HTTP/1.0" 404 153 "-" "Apache-HttpClient/4.5.12 (Java/1.8.0_211)" "----"

问题排查

查看error.log，内如如下：

2022/04/24 11:15:50 [crit] 29097#29097: *2443420 open() "/var/lib/nginx/tmp/client_body/0000000419" failed (13: Permission denied), client: 10.171.81.1, server: xxxxxxx, request: "POST xxxxx HTTP/1.0", host: "xxxxx"
2022/04/24 11:15:50 [error] 29097#29097: *2443420 open() "/xxxxxx/50x.html" failed (2: No such file or directory), client: 10.171.81.1, server: xxxxx, request: "POST /xxxxxx HTTP/1.0", host: "xxxxxx"

1、首先排查了目录/var/lib/nginx/tmp/client_body的权限是否与php-fpm nginx 用户是否一致 ps aux|grep php

2、查看nginx.conf配置，增加client_body_buffer_size和client_max_body_size配置。

问题原因

nginx中的client_body_buffer_size和client_max_body_size默认较小，所以当回调参数过大时，会导致nginx错误，导致接口返回404。这就是为什么postman请求成功（因为没传参数），而程序调用失败的原因。
