一篇快速解决Nginx Post请求405 (Not Allowed)异常的方案

原因在上一篇提到Failed to load resource: the server responded with a status of 405 (Not Allowed)

少说话上代码:

```java
 location /api/ {
       
        proxy_pass   http://172.0.0.1:8085;
        proxy_redirect off;
        proxy_set_header Host $http_host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }

可以保证post请求变成get时，重定向到后台请求的参数不会丢失。
