nginx錯誤重定向代理

目前有一個需求，生產ip爲  http://pro.com，開發ip爲 http://dev.com，當請求生產服務器出錯時，將請求發送到開發服務器，從開發服務器中獲取數據。

獲取錯誤代碼必須配置這一項：

proxy_intercept_errors on;

代理轉發配置：

error_page 404 @error;
location @error {
	return 307 http://dev.com$uri?$args;
}

完整的配置如下：

http {

	sendfile on;
	tcp_nopush on;
	tcp_nodelay on;
	keepalive_timeout 65;
	types_hash_max_size 2048;
	include /etc/nginx/mime.types;
	default_type application/octet-stream;
	ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
	ssl_prefer_server_ciphers on;
	access_log /var/log/nginx/access.log;
	error_log /var/log/nginx/error.log;
	gzip on;
	fastcgi_intercept_errors on;
	proxy_intercept_errors on;
	gzip_disable "msie6";
	include /etc/nginx/conf.d/*.conf;
	include /etc/nginx/sites-enabled/*;
        server {
                listen 8080;
                server_name 127.0.0.1;
		proxy_connect_timeout 1200s;
                proxy_send_timeout 1200s;
                proxy_read_timeout 1200s;
            	proxy_set_header Host $host:$server_port;
                location / {
			proxy_pass http://pro.com;
                	}
		error_page 404 @error;
		location @error {
			return 307 http://dev.com$uri?$args;
         }
	}
}
