用Nginx代理Gunicorn启动的flask应用时,redirect忽略了端口?

问题描述

服务器Gunicorn运行在8000端口。Nginx监听443。。。

server {listen 443;server_name _;location / {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;proxy_set_header X-Forwarded-Proto $scheme;}location /static {alias /home/tiweb/SecPostsWeb/app/static;}

使用了blueprint,分为main和auth

from .main import main as main_blueprint app.register_blueprint(main_blueprint) from .auth import auth as auth_blueprint app.register_blueprint(auth_blueprint, url_prefix=’/auth’)

这是登录的view函数:

@auth.route(’/login’, methods=[’GET’, ’POST’])def login(): form = LoginForm() if form.validate_on_submit():user = User.objects(email=form.email.data).first()if user is not None and user.verify_password(form.password.data): login_user(user, form.remember_me.data) return redirect(request.args.get(’next’) or url_for(’main.index’))flash(’Invalid username or password.’) return render_template(’auth/login_v3.html’, form=form)

执行登录时,从ip:443/auth/login跳转到了ip/index,直接忽略掉了端口。然而直接访问Gunicorn就没有这种问题,怀疑是Nginx设置有问题。求解。。。

问题解答

回答1:

解决方案:nginx设置:忽略了代理的端口,添加上就好proxy_set_header Host $host:$server_port;例如:如果,你设置proxy_set_header Host $host:2345;,当redirect(’index’),你flask实例就会重定向到$host:2345/index
