swagger中，发现使用的SSL证书之后，nginx总是跳转的地址不对，后发现需要增加如下两句代码才正常：

proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Port $server_port;

而如果是iis的话，添加如下：

<appSettings>
    <add key="aspnet:UseHostHeaderForRequestUrl" value="true"/>
</appSettings>

完整nginx配置如下：

server {
        listen       443;
        server_name  www.52jiagou.com;
	
	add_header Content-Security-Policy upgrade-insecure-requests;
	proxy_set_header Host $host;
        proxy_set_header  X-Real-IP  $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header X-Forwarded-Port $server_port;

        ssl                  on;
        ssl_certificate      /cert/www.52jiagou.com/www.52jiagou.com.pem;
        ssl_certificate_key  /cert/www.52jiagou.com/www.52jiagou.com.key;

        ssl_session_timeout  5m;

        ssl_protocols  TLSV1 TLSv1.1 TLSv1.2;
        ssl_ciphers  HIGH:!aNULL:!MD5;
        ssl_prefer_server_ciphers   on;

        location / {
            root   html;
            index  index.html index.htm;

    	    proxy_pass http://127.0.0.1:1234/;

        }
	location /api/Admin/Delivery/ {
	    proxy_pass http://127.0.0.1/api/Admin/Delivery/;

        }

}
