nginx反向代理的问题：报错

nginx配置的ci框架，端口是83

server {
        listen       83;
        server_name  evil.qtyd.com phpStudy.net;
        root   "E:/evil.qtyd.com/CodeIgniter-3.1.3";
        location / {
            index  index.html index.htm index.php;
            #autoindex  on;
        }
        location ~ \.php(.*)$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            fastcgi_param  PATH_INFO  $fastcgi_path_info;
            fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
            include        fastcgi_params;
        }
        
        location ^~ /get/ { #反向代理调试
           proxy_pass http://127.0.0.1:8787/;
        }
        
        if (!-e $request_filename) {
            rewrite ^/(.*)$ /index.php/$1 last;
            break;
        }
}

现在node监听了8787端口

router.get('/get.php', function (req, res) {
    console.log(req.query);
    res.header("Content-Type", "application/json;charset=utf-8");
  res.json(req.query);
  res.end();
})

我在浏览器访问http://127.0.0.1:83/get/get.php为什么没有跳过去
