如果我试图访问站点根目录中不存在的任何内容,即。http://example.com/unexisting.php,我使用以下配置从我的自定义404页面得到了正确的好答案:
server_name example.com;
root /path/to/example;
index index.php;
error_page 404 /not_found.php;
location ~ index.php
{
try_files $uri/index.php =404;
return 301 $scheme://$server_name/;
}
location ~ not_found.php
{
root /path/to/example;
allow all;
internal;
fastcgi_intercept_errors off;
fastcgi_param SCRIPT_FILENAME $document_root/not_found.php;
include fastcgi_params;
}
location = /
{
try_files $uri/index.php @static;
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
include fastcgi_params;
}
location ~ .php$
{
try_files $uri $uri/ =404;
fastcgi_split_path_info ^(.+.php)(/.+)$;
fastcgi_intercept_errors on;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
location @static
{
try_files $uri $uri/ =404;
expires max;
}
location /
{
try_files /something_non_existing @static;
}
如果我试图访问根文件夹之外的文件,即"http://example.com/unexisting_dir/unexisting.php",404页面在屏幕上,但没有任何图形。因为日志中有类似"GET/unexpisting_dir/images/some_image_for_404_page.png HTTP/1.1"的内容,nginx什么都不返回,因为它从用户请求中有一个错误的基。同时,我检查了$document_root是否有正确的基,所以php-fpm运行得很好。
问题是如何让nginx在为404页面提供未存在的嵌套(嵌入)目录服务的情况下忽略用户的URI(而不会重定向和损害任何潜在的东西)
非常感谢!
这是"fastcgi_params"(以防万一):
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_param SCRIPT_NAME $fastcgi_script_name;
fastcgi_param REQUEST_URI $request_uri;
fastcgi_param DOCUMENT_URI $document_uri;
fastcgi_param DOCUMENT_ROOT $document_root;
fastcgi_param SERVER_PROTOCOL $server_protocol;
fastcgi_param HTTPS $https if_not_empty;
fastcgi_param GATEWAY_INTERFACE CGI/1.1;
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;
fastcgi_param REMOTE_ADDR $remote_addr;
fastcgi_param REMOTE_PORT $remote_port;
fastcgi_param SERVER_ADDR $server_addr;
fastcgi_param SERVER_PORT $server_port;
fastcgi_param SERVER_NAME $server_name;
fastcgi_param REDIRECT_STATUS 200;
fastcgi_pass unix:/var/run/php5-fpm.sock;
这里的问题不是nginx。它正确地返回not_found.php 的输出
您需要确保输出包含图像的绝对路径,而不是HTML中的相对路径。例如
<img src="/notfound.jpg" />
代替
<img src="notfound.jpg" />
额外的正斜杠告诉浏览器从文档根而不是浏览器请求的当前"目录"请求图像。
