Ngx跨域解决方法

一个完整的内核优化配置

JavaScript JS 跨域问题

HTTP 错误 405 - 用于访问该页的 HTTP 动作未被许可

HTTP 错误 405.0 - Method Not Allowed

Method = "OPTIONS" | "GET" | "HEAD" | "POST" | "PUT" | "DELETE" | "TRACE" | "CONNECT" | extension-method
extension-method = token

在Nginx配置文件nginx.conf加入如下代码：

location / {

        # 跨域设置
        add_header Access-Control-Allow-Origin *;
        add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';
        add_header 'Access-Control-Allow-Credentials' 'true'; 
       
        if ( $request_method = 'OPTIONS' ) { return 200; }

 }

或者

location / {
        if (!-e $request_filename){
            rewrite  ^(.*)$  /index.php?s=$1  last;   break;
        }
        
        if ($request_method = 'OPTIONS') { 
        　　add_header Access-Control-Allow-Origin *; 
        　　add_header Access-Control-Allow-Credentials true; 
        　　add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS'; 
        　　#add_header '*'; 
        　　return 200; 
        }

        if ($request_method = 'POST') {
        　　add_header 'Access-Control-Allow-Origin' *; 
        　　add_header 'Access-Control-Allow-Credentials' 'true'; 
        　　add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; 
        　　#add_header '*';
        }

        if ($request_method = 'GET') {
        　　add_header 'Access-Control-Allow-Origin' *; 
        　　add_header 'Access-Control-Allow-Credentials' 'true'; 
        　　add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS'; 
        　　#add_header '*';
        }
 }
