301对HTTP的永久重定向，但HTTP效果很好

Question

当我运行

时

curl -I http://myapp.com/
curl -I https://myapp.com/

http返回

HTTP/1.1 200 OK
Server: nginx
Date: Tue, 05 Mar 2019 17:46:29 GMT
Content-Type: text/html
Content-Length: 612
Last-Modified: Tue, 31 Jan 2017 15:01:11 GMT
Connection: keep-alive
ETag: "5890a6b7-264"
Accept-Ranges: bytes

而https返回

HTTP/1.1 301 Moved Permanently
Server: nginx/1.10.3 (Ubuntu)
Date: Tue, 05 Mar 2019 17:50:29 GMT
Content-Type: text/html
Content-Length: 194
Connection: keep-alive
Location: https://www.myapp.com/
curl: (47) Maximum (50) redirects followed

我显然无法访问该域，我会收到错误ERR_TOO_MANY_REDIRECTS，因为我们设置了Encrypt以将任何HTTP请求重定向到HTTPS。

我看到了两个选项，请停用https并通过http访问网站或弄清楚为什么301 Permanent Redirect在https上发生。

我最初通过取出该行

在http上摆脱了301 Permanent Redirect

return 301 https://$server_name$request_uri;

我的nginx配置文件

server {
listen 80;
servername myapp.com www.myapp.com;
servertokens off;
}
server {
listen 443 ssl; # managed by Certbot
server_name myapp.com www.myapp.com;
ssl_certificate /etc/letsencrypt/live/myapp.com/fullchain.pem; # managed by Certbot
ssl_certificate_key /etc/letsencrypt/live/myapp.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  
root /home/me/myapp/src/myapp;
location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
    root /home/me/myapp/src/myapp;
}
location /media/  {
    root /home/me/myapp/src/myapp;
}
location / {
    try_files $uri/ @python_django;
}
location @python_django {
    proxy_pass http://127.0.0.1:8001;
    proxy_pass_request_headers on;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header Host $http_host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_redirect off;
}
}

我迫切需要帮助！

您可以遵循此替代方法。我发现处理重定向更简单。

server {
    listen 80;
    #listen [::]:80 ipv6only=on;
    server_name your.server.com;
    access_log /etc/nginx/access.log;
    root /var/www/html/someroot;
    location / {
            #autoindex on;
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            # try_files $uri =404;
            #proxy_set_header X-Real-IP $remote_addr;
            #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #proxy_set_header Host $http_host;
            #proxy_set_header X-NginX-Proxy true;
            #proxy_pass http://127.0.0.1:8080/;
            #proxy_redirect off;
            #proxy_http_version 1.1;
            #proxy_set_header Upgrade $http_upgrade;
            #proxy_set_header Connection "upgrade";
            #proxy_redirect off;
            #proxy_set_header   X-Forwarded-Proto $scheme;
            #proxy_cache one;
            #proxy_cache_key sfs$request_uri$scheme;
    }
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/some/fullchain.pem;
    # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/some/privkey.pem; 
    # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    if ($scheme != "https") {
        return 301 https://$host$request_uri;
    }
}

注意最后一个子句。那就是所有重定向发生的地方。基本上，您仅使用一个服务器块，然后收听通过端口80和443的所有流量。当某人击中端口80时，请求将重定向到443。对我来说效果很好。让我知道它是否也适合您。
