问题描述
我做了很多研究,并更改了代码以尝试解决此问题,但是没有任何效果。 Flask路由重定向现在可以与Nginx和Certbot一起正常使用。进入网站可以正常工作,单击导航中的链接也可以正常工作,但是当Flask尝试重定向到另一个URL(Flask路由)时,它将创建一个如下所示的无效URL:
https://example.com/signup
提交表单(POST)请求后,这就是我看到的URL。
https://example.com,example.com/login
这是Flask Python代码:
@main.route('/signup',methods=['GET','POST'])
def sign_up():
'''sign up user'''
form = SignupForm()
if form.validate_on_submit():
return redirect(url_for('main.login'))
return render_template('main/signup.html',form=form)
@main.route('/login','POST'])
def login():
'''login user'''
form = LoginForm()
if form.validate_on_submit():
pass
return render_template('main/login.html',form=form)
Nginx网站配置:
server {
server_name example.com www.example.com;
location / {
include proxy_params;
proxy_pass http://unix:/var/www/example/example.sock;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
}
listen 443 ssl; # managed by Certbot
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot
include /etc/letsencrypt/options-ssl-Nginx.conf; # managed by Certbot
ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
server {
if ($host = www.example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
if ($host = example.com) {
return 301 https://$host$request_uri;
} # managed by Certbot
listen 80;
server_name example.com www.example.com;
return 404; # managed by Certbot
}
如果我手动键入此代码,它将起作用,这意味着Python / Flask代码可以。
https://example.com/login
解决方法
解决方案在Nginx位置块中。注意行 include proxy_params; 。最终两次包含相同的信息。
location / {
include proxy_params;
proxy_pass http://unix:/var/www/example/example.sock;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
}
由于文件/ etc / nginx / proxy_params包含proxy_set_header信息,因此我不必再次添加它。现在,位置块看起来像这样。
location / {
include proxy_params;
proxy_pass http://unix:/var/www/example/example.sock;
}
