Question

我有一个非常奇怪的问题。我的服务器通过proxypass连接到我的api。

server {
    listen   80;
    server_name  www.example.com;

    location / {
        root    /data/sites/www.example.com/public_html/;
        index  index.php index.html index.htm;
        try_files $uri $uri/ /index.php?rt=$uri&$args;
    }

    location /api {
        proxy_pass_header  Set-Cookie;

        proxy_pass_header  P3P;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Fowarded-Host $host;
        proxy_set_header   X-Real-IP $remote_addr;
        port_in_redirect off;
        proxy_http_version 1.1;
        proxy_set_header Connection "";
        proxy_pass https://api.example.com/;
        proxy_connect_timeout 60;
    }

    location ~ \.php$ {
        root    /data/sites/www.example.com/public_html/;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index  index.php;
        #fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_param  PATH_INFO        $fastcgi_path_info;
        fastcgi_param  ENV  production;
        fastcgi_param HTTPS off;
        fastcgi_read_timeout 300;
    }

}

因此，网址www.example.com/api是api.example.com的代理传递。但连接总是超时。现在如果我直接在我的浏览器中访问api.example.com，它就可以了！

所以我感到困惑。任何人都有什么想法可以发生什么？

Answer 1

如果api.example.com是DNS名称而不是upstream标签，则可能需要添加解析程序语句以授予nginx DNS访问权限。

resolver 8.8.8.8;
proxy_pass https://api.example.com/;
