我希望实现的目标是将裸域的任何请求重定向到www域.这是一个示例配置.
server {
listen 8080;
server_name localhost;
location / {
if ($http_host !~* "^www\.") {
rewrite (.*) http://www.$http_host$request_uri permanent;
}
}
}
我得到的结果是：
curl -I http://127.0.0.1:8080/pp/\?a\=b
HTTP/1.1 301 Moved Permanently
Server: Nginx/1.6.2
Date: Thu,22 Jan 2015 04:07:39 GMT
Content-Type: text/html
Content-Length: 184
Connection: keep-alive
Location: http://www.127.0.0.1:8080/pp/?a=b?a=b
查询参数在结果中重复;我在这里错过了什么吗？
最佳答案
您看到的查询参数的复制是Nginx的预期行为.要更改此设置,您需要添加尾随？重写如下：
server {
listen 8080;
server_name localhost;
location / {
if ($http_host !~* "^www\.") {
rewrite (.*) http://www.$http_host$request_uri? permanent;
}
}
}
If a replacement string includes the new request arguments,the
prevIoUs request arguments are appended after them. If this is
undesired,putting a question mark at the end of a replacement string
avoids having them appended,for example:rewrite ^/users/(.*)$/show?user=$1? last;
但是,Aleksey Deryagin给出的配置对于您所需的重定向类型来说是更好,更有效的选项,因为无论是否需要,每个请求都将由原始配置中的if块进行评估.
