nginx 反向代理未传递请求

我有一个域名 (example.com) 和一个子域名 (sub.example.com)，它们都托管在同一台服务器上。我想代理请求，以便http://sub.example.com/api/将于http://example.com/api/（以及参数）这是我的来自 sub.example.com 的 nginx 代码：

location /api {
    rewrite /api/(.*) /api/$1 break;
    proxy_pass http://example.com/api;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_redirect off;
    proxy_buffering off;
}

这对我来说不起作用。有效的是：

location ~* ^/api/(.*)$ {
    rewrite ^/api/(.*)$ http://example.com/api/$1 last;
}

编辑：我忘了说我的服务器定义包含一些有关 Yii 框架和 php 文件解析的规则。以下是完整的服务器语句：

server {
        listen 80;
        server_name sub.example.com;
        access_log /var/log/nginx/sub.example.com.access_log main;
        error_log /var/log/nginx/sub.example.com.error_log info;
        root /var/www/localhost/htdocs/sub.example.com;
        index index.php index.html index.htm default.html default.htm;

#       location ~* ^/api/(.*)$ {
#                       rewrite ^/api/(.*)$ http://example.com/api/$1 last;
#               }

        location /api {
                        rewrite /api/(.*) /api/$1 break;
                        proxy_pass http://example.com/api;
                        proxy_set_header X-Real-IP $remote_addr;
                        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
#                        proxy_set_header Host $http_host;
                        proxy_redirect off;
                        proxy_buffering off;
                        break;
        }

        location / {
                if (-f $request_filename) {
                        #expires max;
                        break;
                }
                if (!-e $request_filename) {
                        rewrite ^/(.*)$ /index.php?/$1 last;
                }
        }
        location /index.php {
                include /etc/nginx/fastcgi.conf;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME /path-to/index.php;
                fastcgi_param  REQUEST_URI      $request_uri;
                fastcgi_param  QUERY_STRING     $query_string;
                fastcgi_param  REQUEST_METHOD   $request_method;
                fastcgi_param  CONTENT_TYPE     $content_type;
                fastcgi_param  CONTENT_LENGTH   $content_length;
                fastcgi_pass 127.0.0.1:9000;
        }


        location ~ \.php$ {
                        fastcgi_pass  127.0.0.1:9000;
                        include /etc/nginx/fastcgi.conf;
                        fastcgi_index index.php;
                        fastcgi_intercept_errors on; # for easier debug
                }
}

您正在将初始请求Host标头传递sub.example.com给example.com：

proxy_set_header Host $http_host;

代理请求时，它可能会落在sub.example.comvhost 或默认 vhost 中，而不是example.comvhost，这取决于您的设置。

删除此行。
