nginx uri和request_uri区别

Posted 2020-09-26 行知笔记

$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" 

这个变量等于从客户端发送来的原生请求URI，包括参数。它不可以进行修改。$uri变量反映的是重写后/改变的URI。不包括主机名。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 

这个变量指当前的请求URI，不包括任何参数(见$args)。这个变量反映任何内部重定向或index模块所做的修改。注意，这和$request_uri不同，因$request_uri是浏览器发起的不做任何修改的原生URI。不包括协议及主机名。例如："/foo/bar.html"

 

$document_uri

The same as $uri. 

 

nginx内置变量汇总：

Embedded Variables

The ngx_http_core_module module supports embedded variables with names matching the Apache Server variables. First of all, these are variables representing client request header fields, such as $http_user_agent, $http_cookie, and so on. Also there are other variables:

$arg_name

argument name in the request line

$args

arguments in the request line

$binary_remote_addr

client address in a binary form, value’s length is always 4 bytes for IPv4 addresses or 16 bytes for IPv6 addresses

$body_bytes_sent

number of bytes sent to a client, not counting the response header; this variable is compatible with the “%B” parameter of the mod_log_config Apache module

$bytes_sent

number of bytes sent to a client (1.3.8, 1.2.5)

$connection

connection serial number (1.3.8, 1.2.5)

$connection_requests

current number of requests made through a connection (1.3.8, 1.2.5)

$content_length

“Content-Length” request header field

$content_type

“Content-Type” request header field

$cookie_name

the name cookie

$document_root

root or alias directive’s value for the current request

$document_uri

same as $uri

$host

in this order of precedence: host name from the request line, or host name from the “Host” request header field, or the server name matching a request

$hostname

host name

$http_name

arbitrary request header field; the last part of a variable name is the field name converted to lower case with dashes replaced by underscores

$https

“on” if connection operates in SSL mode, or an empty string otherwise

$is_args

“?” if a request line has arguments, or an empty string otherwise

$limit_rate

setting this variable enables response rate limiting; see limit_rate

$msec

current time in seconds with the milliseconds resolution (1.3.9, 1.2.6)

$nginx_version

nginx version

$pid

PID of the worker process

$pipe

“p” if request was pipelined, “.” otherwise (1.3.12, 1.2.7)

$proxy_protocol_addr

client address from the PROXY protocol header, or an empty string otherwise (1.5.12)

The PROXY protocol must be previously enabled by setting the proxy_protocol parameter in the listen directive.

$proxy_protocol_port

client port from the PROXY protocol header, or an empty string otherwise (1.11.0)

The PROXY protocol must be previously enabled by setting the proxy_protocol parameter in the listen directive.

$query_string

same as $args

$realpath_root

an absolute pathname corresponding to the root or alias directive’s value for the current request, with all symbolic links resolved to real paths

$remote_addr

client address

$remote_port

client port

$remote_user

user name supplied with the Basic authentication

$request

full original request line

$request_body

request body

The variable’s value is made available in locations processed by the proxy_pass, fastcgi_pass,uwsgi_pass, and scgi_pass directives when the request body was read to a memory buffer.

$request_body_file

name of a temporary file with the request body

At the end of processing, the file needs to be removed. To always write the request body to a file,client_body_in_file_only needs to be enabled. When the name of a temporary file is passed in a proxied request or in a request to a FastCGI/uwsgi/SCGI server, passing the request body should be disabled by the proxy_pass_request_body off, fastcgi_pass_request_body off,uwsgi_pass_request_body off, or scgi_pass_request_body off directives, respectively.

$request_completion

“OK” if a request has completed, or an empty string otherwise

$request_filename

file path for the current request, based on the root or alias directives, and the request URI

$request_id

unique request identifier generated from 16 random bytes, in hexadecimal (1.11.0)

$request_length

request length (including request line, header, and request body) (1.3.12, 1.2.7)

$request_method

request method, usually “GET” or “POST”

$request_time

request processing time in seconds with a milliseconds resolution (1.3.9, 1.2.6); time elapsed since the first bytes were read from the client

$request_uri

full original request URI (with arguments)

$scheme

request scheme, “http” or “https”

$sent_http_name

arbitrary response header field; the last part of a variable name is the field name converted to lower case with dashes replaced by underscores

$sent_trailer_name

arbitrary field sent at the end of the response (1.13.2); the last part of a variable name is the field name converted to lower case with dashes replaced by underscores

$server_addr

an address of the server which accepted a request

Computing a value of this variable usually requires one system call. To avoid a system call, the listendirectives must specify addresses and use the bind parameter.

$server_name

name of the server which accepted a request

$server_port

port of the server which accepted a request

$server_protocol

request protocol, usually “HTTP/1.0”, “HTTP/1.1”, or “HTTP/2.0”

$status

response status (1.3.2, 1.2.2)

$tcpinfo_rtt, $tcpinfo_rttvar, $tcpinfo_snd_cwnd, $tcpinfo_rcv_space

information about the client TCP connection; available on systems that support the TCP_INFO socket option

$time_iso8601

local time in the ISO 8601 standard format (1.3.12, 1.2.7)

$time_local

local time in the Common Log Format (1.3.12, 1.2.7)

$uri

current URI in request, normalized

The value of $uri may change during request processing, e.g. when doing internal redirects, or when using index files.
