生成 links_json.py

python links_title_dumper.py > links_json.py

NGINX 配置

  location / {
     try_files $uri $uri/ /index.php?$args @fetch;
  }

  location @fetch {
      # 放错误页面的目录路径。
      proxy_pass http://127.0.0.1:5000;
  }

Location的正确配置

如上的配置，真实的URL不能正确传递到Flask服务端。 正确的配置：

location /{
        autoindex off;
        try_files $uri $uri/ @fetch;
}
# 定义错误页面码，如果出现相应的错误页面码，转发到那里。
error_page 404 403 = @fetch;

location @fetch {
    # Redefine the header fields that NGINX sends to the upstream server
    #the name and port of the NGINX server (Host $host)
    proxy_set_header Host $host;

    #the schema of the original client request, as in whether it was an http or an https request:
    proxy_set_header X-Forwarded-Proto $scheme;

    #the IP address of the user (X-Real-IP $remote_addr)
    proxy_set_header X-Real-IP $remote_addr;

    #the IP addresses of every server the client has been proxied through up to this point:
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

    # Define the maximum file size on file uploads
    client_max_body_size 5M;

    # 放错误页面的目录路径。
    proxy_pass http://127.0.0.1:5000;
