nginx反代后域名的重写

今天遇到一个问题：

访问http://teach.xxx.cn/wv/wordviewerframe.aspx?WOPISrc=http%3A%2F%2Fteach.xxx.cn%2Fapi%2Fwopi%2Ffiles%2F644%3FuserId%3D26142

实际地址是：

http://owa.xxx.cn/wv/wordviewerframe.aspx?WOPISrc=http%3A%2F%2Fteach.xxx.cn%2Fapi%2Fwopi%2Ffiles%2F644%3FuserId%3D26142

开始用的反代的方式：

location /wv/ {

proxy_pass          http://owa.xxx.cn;

proxy_redirect    off;

proxy_set_header    Host $host;

proxy_set_header    X-Real-IP              $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 10m;

client_body_buffer_size 128k;

proxy_connect_timeout 90;

proxy_send_timeout 90;

proxy_read_timeout 90;

proxy_buffer_size 4k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

}

不成功：

改为

location /wv/ {

rewrite ^/(.*)$ http://owa.xxxcn/$1 redirect;

proxy_redirect    off;

proxy_set_header    Host $host;

proxy_set_header    X-Real-IP               $remote_addr;

proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;

client_max_body_size 10m;

client_body_buffer_size 128k;

proxy_connect_timeout 90;

proxy_send_timeout 90;

proxy_read_timeout 90;

proxy_buffer_size 4k;

proxy_buffers 4 32k;

proxy_busy_buffers_size 64k;

proxy_temp_file_write_size 64k;

}
