nginx proxy_pass POST 404 错误

nginx proxy_pass POST 404 错误

我有 nginx 代理到应用服务器，具有以下配置：

location /app/ {
        # send to app server without the /app qualifier
        rewrite /app/(.*)$ /$1 break;
        proxy_set_header Host $http_host;
        proxy_pass http://localhost:9001;
        proxy_redirect http://localhost:9001 http://localhost:9000;
    }

任何对 /app 的请求都会转到 :9001，而默认站点托管在 :9000。

GET 请求工作正常。但每当我向 /app/any/post/url 提交 POST 请求时，都会导致 404 错误。通过 GET /app/any/post/url 直接在浏览器中访问 URL 会按预期访问应用服务器。

我在网上找到了其他有类似问题的人，并补充道

proxy_set_header Host $http_host;

但这并没有解决我的问题。

没有记录任何错误，访问日志如下：

# For http://localhost:9000 (no proxying)

任何见解都值得赞赏。

谢谢。

完整配置如下：

server {
    listen   9000; ## listen for ipv4; this line is default and implied
    #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6

    root /home/scott/src/ph-dox/html;
    # root ../html; TODO: how to do relative paths?
    index index.html index.htm;

    # Make site accessible from http://localhost/
    server_name localhost;

    location / {
        # First attempt to serve request as file, then
        # as directory, then fall back to displaying a 404.
        try_files $uri $uri/ /index.html;
        # Uncomment to enable naxsi on this location
        # include /etc/nginx/naxsi.rules
    }

    location /app/ {
        # rewrite here sends to app server without the /app qualifier
        rewrite /app/(.*)$ /$1 break;
        proxy_set_header Host $http_host;
        proxy_pass http://localhost:9001;
        proxy_redirect http://localhost:9001 http://localhost:9000;
    }

    location /doc/ {
        alias /usr/share/doc/;
        autoindex on;
        allow 127.0.0.1;
        allow ::1;
        deny all;
    }

}

我的错，问题不是出在 nginx 上，而是出在我的应用服务器上。我使用的路由模块要求我明确指定请求方法（如果不是 get 方法），所以在发布时会抛出 404 错误，而直接访问浏览器网址时不会抛出错误。
