如何配置 nginx 以将用户信息传递给 wsgi/flask



我有一个nginx http服务器,它对用户进行身份验证,并通过wsgi将经过身份验证的请求传递给Flask应用程序。当我从烧瓶应用程序打印整个标题时,没有可用的用户信息。

是否可以让nginx在请求标头中包含用户名?

这是带有身份验证配置的服务器块...

server {
    listen 80;
    server_name  notes.example.org;
    return 301 https://$server_name$request_uri;   
}
server {

    # SSL configuration
    listen 443;
    listen [::]:443; 
    include snippets/ssl-example.org.conf;
    include snippets/ssl-params.conf;
    server_name  notes.example.org;
    location / {
        auth_basic "Restricted Content";
        auth_basic_user_file /path/to/passwd/file;
        include uwsgi_params;
        uwsgi_pass unix:/path/to/wsgi/socket;
    }

}

在 wsgi 下运行的应用看到的请求标头...

Authorization: Basic **************==
Content-Length: 0
User-Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
Dnt: 1

这里你使用的是http基本认证选项,在nginx服务器给出的成功反馈后,浏览器发送一个base64的username:password。只需使用 Python base64 模块即可获取用户名和密码,

>>> from base64 import b64decode
>>> authorization_header = "dXNlcm5hbWU6cGFzc3dvcmQ=" # value from flask request header
>>> details = b64decode("dXNlcm5hbWU6cGFzc3dvcmQ=")
>>> username, password = details.split(':')
>>> username
'username'
>>> password
'password'
>>>
