我将解析服务器迁移到基于以下文档的DigitalOcean Ubuntu液滴：

https://www.digitalocean.com/community/tutorials/how-to-migrate-a-parse-app-to-parse-server-on-ubuntu-14-04

对于解析服务器的nginx代理(https)请求，我遇到了问题。

如果我在液滴上打开端口1337，并将解析http请求配置为直接转到解析服务器( http://example.com:1337/parse )，那么所有这些都可以正常工作。

如果我将解析http请求配置为转到 https://example.com/parse ，则nginx无法代理解析服务器的请求。

nginx返回404 (这是/ location将做的可疑的事情)。

让我们来加密SSL证书吧，因为我可以提供静态内容(通过301状态将http请求从80重定向到443 )。

我的nginx默认配置如下所示：

# HTTP - redirect all requests to HTTPS
server {
    listen 80;
    listen [::]:80 default_server ipv6only=on;
    return 301 https://$host$request_uri;
# HTTPS - serve HTML from /usr/share/nginx/html, proxy requests to /parse/
# through to Parse Server
server {
    listen 443;
    server_name example.com;
    root /usr/share/nginx/html;
    index index.html index.htm;
    ssl on;
    # Use certificate and key provided by Let's Encrypt:
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
    # Pass requests for /parse/ to Parse Server instance at localhost:1337
    location /parse/ {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://localhost:1337/;
            proxy_ssl_session_reuse off;
            proxy_set_header Host $http_host;
            proxy_redirect off;
    location / {
            try_files $uri $uri/ =404;
}

这是nginx access.log中的一个典型行：

xxx.xxx.xxx.xxx - - [20/Mar/2016:18:54:53 -0400] "PUT /parse/classes/_User/xxxxxxxxxx HTTP/1.1" 404 68 "-" ...

有什么方法可以打开更详细的调试，这样我就可以知道为什么匹配失败了吗？

谢谢，彼得

解决方案(见下文) 注:在proxy_pass配置上添加/解析/

  location /parse/ {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://localhost:1337/parse/;
            proxy_ssl_session_reuse off;
