我使用nginx反代了一個tomcat應用 ip直接訪問時 http://192.168.1.112:8282/bbs
反代是 test-bbs.xx.com

當我登入的時候登錄，bbs應用程式會302跳到首頁就是http://192.168.1.2:8080/bbs
但是我使用nginx 卻跳到了test-bbs .xx.com/bbs

listen       80;
        server_name  test-bbs.xx.com;
        root    html;
        index   index.html;
        access_log  /usr/local/nginx/logs/bbs.access.log;
        error_log  /usr/local/nginx/logs/bbs.error.log;

        location / {
