nginx中，$request_uri和$uri的區別

$request_uri

This variable is equal to the *original* request URI as received from the client including the args. It cannot be modified. Look at $uri for the post-rewrite/altered URI. Does not include host name. Example: "/foo/bar.php?arg=baz" 

這個變量等於從客戶端發送來的原生請求URI，包括參數。它不可以進行修改。$uri變量反映的是重寫后/改變的URI。不包括主機名。例如："/foo/bar.php?arg=baz"

 

$uri

This variable is the current request URI, without any arguments (see $args for those). This variable will reflect any modifications done so far by internal redirects or the index module. Note this may be different from $request_uri, as $request_uri is what was originally sent by the browser before any such modifications. Does not include the protocol or host name. Example: /foo/bar.html 

這個變量指當前的請求URI，不包括任何參數(見$args)。這個變量反映任何內部重定向或index模塊所做的修改。注意，這和$request_uri不同，因$request_uri是瀏覽器發起的不做任何修改的原生URI。不包括協議及主機名。例如："/foo/bar.html"

 

$document_uri

The same as $uri. 

同$uri.
