將 HTTP 從 Nginx 重定向到 HTTPS 無效

Question

輸入： https://example.com => ssl ok但是輸入：www.example.com 和 example.com 是 http沒有重定向到 881056383.5270。

WordPress 地址（URL）和站點地址（URL）：https//example.com

/etc/nginx/conf.d/example.com.conf

server {
listen 80; 
server_name example.com www.example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
server_name example.com www.example.com;
ssl on;
ssl_certificate /etc/nginx/ssl/cert_chain.crt;
#ssl_CACertificate_File /etc/nginx/ssl/example.com.ca-bundle;
ssl_certificate_key /etc/nginx/ssl/example.com.key; 
access_log off;
# access_log /home/example.com/logs/access_log;
error_log off;
# error_log /home/example.com/logs/error.log; 
add_header X-Frame-Options SAMEORIGIN;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";
root /home/example.com/public_html;
include /etc/nginx/conf/ddos2.conf;
index index.php index.html index.htm;
server_name example.com;

如何解決？ 抱歉我的英語不好，謝謝。

Answer 1

這可能確實是由不明確的服務器名稱引起的。 嘗試使用以下方法：

server {

    server_name example.com www.example.com;
    listen 80;
    listen 443 ssl; # Listen for SSL at port 443 as well

    # ... other config - certificates and such

    # If a user tries to come through http, redirect them through https
    if ($scheme != "https") { 
        return 301 https://$host$request_uri;
    }
}

您可以通過運行sudo nginx -t來檢查您的 nginx 配置。

Answer 2

我有類似的問題。 它是由 linux 防火牆引起的（80 端口被禁止）。

Answer 3

您的配置不清楚，最后您有一個重復的server_name example.com行。

嘗試使用這個：

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name example.com www.example.com;
    return 301 https://$server_name$request_uri;
}

Answer 4

更新這一行 return 301 https://$server_name$request_uri;

返回 301 https://$http_host$request_uri

Answer 5

我也有與 nginx 相同的問題，所以我將這些應用於服務器以僅接受一個請求，該請求將決定 http 和 https

server { 
    listen 80 ;
    listen [::]:80 ;
    listen 443 ssl http2 ;
    listen [::]:443 ssl http2 ;
    server_name example.com www.example.com; 

    #------ ssl certificates and other config --------

    set $https_redirect 0;
    #if request came from port 80/http
    if ($server_port = 80) { 
        set $https_redirect 1; 
    }
    # or if the requested host came with www 
    if ($host ~ '^www\.') { 
        set $https_redirect 1; 
    }
    #then it will redirects
    if ($https_redirect = 1) {
        return 301 https://example.com$request_uri;
    }
}

通過使用這個我只有服務器塊來處理任何請求

此代碼將幫助您重定向到 https：

假設您輸入http://www.example.com ，然后它將重定向到https://www.example.com
, 如果有人輸入 http:example.com，它會重定向到https://www.example.com

<VirtualHost *:80>
ServerName www.example.com
DocumentRoot /usr/local/apache2/htdocs
Redirect permanent / https://www.example.com/
</VirtualHost>
<VirtualHost_default_:443>
ServerName www.example.com
DocumentRoot /usr/local/apache2/htdocs
SSLEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^example\.com$
RewriteRule (.*) https://www.example.com/$1 [R=301,L]
</VirtualHost>
