通过Nginx配置转发到Flask应用
server { listen 80; server_name _; access_log /var/log/nginx/access.log; error_log /var/log/nginx/error.log; 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 $scheme; } }
配置中明明已经有$scheme
字段配置了,Flask中只能获取到http,而不是https
还需要在Flask应用中加入以下代码才能生效
from werkzeug.middleware.proxy_fix import ProxyFix app.wsgi_app = ProxyFix(app.wsgi_app, x_proto=1, x_host=1)
