Nginx
Nginx 配置在嘗試將 www 重定向到非 www 和 https 時不斷拋出重定向循環
我正在嘗試將所有對我的域的請求重新定向
www到非 www url，並將所有請求同時重定向到https。這是我的 nginx 配置：server { listen 80; server_name example.com www.example.com; location '/.well-known' { default_type "text/plain"; root /home/letsencrypt; allow all; } return 301 https://example.com$request_uri; } server { listen 443 ssl http2; server_name www.example.com; include snippets/ssl-example.com.conf; include snippets/ssl-params.conf; location '/.well-known' { default_type "text/plain"; root /home/letsencrypt; allow all; } return 301 https://example.com$request_uri; } server { listen 443 ssl http2; server_name example.com; access_log /var/log/nginx/slmun.access.log; error_log /var/log/nginx/slmun.error.log; include snippets/ssl-example.com.conf; include snippets/ssl-params.conf; location '/.well-known' { default_type "text/plain"; root /home/letsencrypt; allow all; } location / { proxy_pass http://127.0.0.1:8000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forward-Proto http; proxy_set_header X-Nginx-Proxy true; proxy_redirect off; } }問題是，我在這裡得到了一個重定向循環。瀏覽器說
example.com redirected you too many times.。知道發生了什麼嗎？<html> <head><title>301 Moved Permanently</title></head> <body bgcolor="white"> <center><h1>301 Moved Permanently</h1></center> <hr><center>nginx/1.10.3</center> </body> </html>這是訪問日誌條目：
162.158.165.25 - - [20/Mar/2017:07:50:53 +0530] "GET / HTTP/1.1" 301 185 "-" "curl/7.47.0"奇怪的 https 也被重定向。
捲曲
slmun.org（這是真正的域）：<html> <head><title>301 Moved Permanently</title></head> <body bgcolor="white"> <center><h1>301 Moved Permanently</h1></center> <hr><center>nginx/1.10.3</center> </body> </html>這是訪問日誌條目：
162.158.165.25 - - [20/Mar/2017:07:51:49 +0530] "GET / HTTP/1.1" 301 185 "-" "curl/7.47.0"www 的也有相同的結果。
您沒有在問題中提到您正在使用 CloudFlare。我相信問題出在 CloudFlare，無論是記憶體結果還是 PageRule。在進行此診斷時，清除您的 CloudFlare 記憶體並禁用任何頁面規則。
下一個選項是您的代理應用程序發送重定向。查看 Nginx 和代理應用的訪問日誌確認。
如果您對此不滿意，請發布您的 CloudFlare 配置和 Nginx 配置文件的螢幕截圖，以及代理配置的日誌。
這是來自 Firefox 的帶有 Live HTTP Headers 外掛的請求/響應標頭。我可以確認一個循環重定向。
