Python 通过gunicorn和nginx使用flask googlelogin导致400个错误请求

更新：当我将我的nginx服务器配置为允许http并将googleoauth的重定向URI设置为使用http（而不是https）时，它似乎可以工作。我真的更喜欢使用HTTPS，所以任何想法都很感激

---

我正在尝试使用flask googlelogin插件授权用户访问我的web应用程序。当运行调试服务器并直接连接到它时，一切正常，但当我在nginx后面运行我的应用程序作为反向代理时（无论是到调试服务器还是到运行在gunicorn内部的应用程序），我的登录回调上会收到

400个错误请求

响应，上面写着“浏览器（或代理）”发送了此服务器无法理解的请求”

gunicorn日志（使用gunicorn运行时）没有显示任何有趣的内容。nginx日志（在

info

级别）显示返回的400：

» tail -f /var/log/nginx/*

==> /var/log/nginx/access.log <==
76.164.174.115 - - [21/May/2014:13:07:46 -0500] "GET /login HTTP/1.1" 200 1368 "-" "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36"
76.164.174.115 - - [21/May/2014:13:07:49 -0500] "GET /oauth2callback?state=[redacted]&code=[redacted] HTTP/1.1" 400 192 "https://redacted.com/login" "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.131 Safari/537.36"

因此GET被代理给应用程序，但出于某种原因flask不喜欢它。以下是我申请的相关部分：

from flask import Flask, request, render_template, redirect, url_for, flash, session
from flask_login import current_user, login_required, login_user, logout_user, UserMixin, LoginManager
from flask_googlelogin import GoogleLogin
from werkzeug.contrib.fixers import ProxyFix
import json

app = Flask(__name__)
app.wsgi_app = ProxyFix(app.wsgi_app)
app.secret_key = "redacted"
app.config.update(
    GOOGLE_LOGIN_CLIENT_ID='redacted',
    GOOGLE_LOGIN_CLIENT_SECRET='redacted',
    GOOGLE_LOGIN_REDIRECT_URI='https://redacted.com/oauth2callback',
)

login_manager = LoginManager()
login_manager.init_app(app)
login_manager.login_view = "login"
login_manager.login_message = u"Please log in to access this page."
login_manager.login_message_category = u"danger"
googlelogin = GoogleLogin(app, login_manager)

class User(UserMixin):
    def __init__(self, userinfo):
        self.name = userinfo['name']
        self.id = userinfo['id']
        self.picture = userinfo.get('picture')

users = {
    "redacted1" : None,
    "redacted2" : None,
}

@googlelogin.user_loader
@login_manager.user_loader
def load_user(userid):
    return users.get(userid)

@app.route("/login", methods=['GET', 'POST'])
def login():
    return render_template('login.html', login_url=googlelogin.login_url())

@app.route('/oauth2callback')
@googlelogin.oauth2callback
def oauth2callback(token, userinfo, **params):
    if userinfo['id'] in users:
        user = users[userinfo['id']] = User(userinfo)
        login_user(user)
        session['token'] = json.dumps(token)
        flash("Logged in", "success")
        return redirect(params.get('next', url_for('automation')))
    else:
        flash("That google user is not authorized.", "danger")
        return redirect(url_for('login'))

@app.route("/automation", methods=['GET'])
@login_required
def automation():
    return render_template('automation.html')

@app.route("/logoff")
@login_required
def logoff():
    logout_user()
    session.clear()
    flash("logged out", "info")
    return redirect(url_for('login'))

if __name__ == "__main__":
    app.config.update( GOOGLE_LOGIN_REDIRECT_URI='http://localhost:5000/oauth2callback' )
    app.run(debug=True)

烧瓶中出现

400个错误请求的常见原因似乎是视图函数中未捕获的异常，但我已尝试将整个
oauth2callback
缩减为只有
print
和
pass
的状态，但仍然失败，并且我看不到打印输出

以下是我的nginx配置的相关部分：

server {
    listen 443;
    server_name redacted.com www.redacted.com;

    root /usr/share/nginx/www;
    index index.html index.htm;

    ssl on;
    ssl_certificate /etc/ssl/certs/ssl-bundle.pem;
    ssl_certificate_key /etc/ssl/private/myserver.key;

    ssl_session_timeout 5m;

    ssl_protocols SSLv3 TLSv1;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv3:+EXP;
    ssl_prefer_server_ciphers on;

    location / {
            try_files $uri $uri/ @proxy_to_app;
    }

    location @proxy_to_app {
            proxy_pass http://127.0.0.1:8000;
            proxy_redirect off;

            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

提前感谢。
我在使用uwsgi时遇到了同样的问题

我可以通过在我的
/etc/nginx/uwsgi_参数中添加以下行来修复它

uwsgi_param  UWSGI_SCHEME       $server_protocol;

我还添加了我的app.config

app.config['GOOGLE_LOGIN_REDIRECT_SCHEME'] = "https"

祝你好运

app.config['GOOGLE_LOGIN_REDIRECT_SCHEME'] = "https"
