DESCRIPTION
This program can be used to send requests toWWW
servers and your
local file system. The request content for POST
and PUT
methods is read from stdin. The content of the response is printed on
stdout. Error messages are printed on stderr. The program returns a
status value indicating the number of URLs that failed.
The options are:
- -m <method>
- Set which method to use for the request. If this option is not used, then the method is derived from the name of the program.
- -f
- Force request through, even if the program believes that the method is illegal. The server might reject the request eventually.
- -b <uri>
-
This URIwill be used as the baseURIfor resolving all relative URIs given as argument.
- -t <timeout>
- Set the timeout value for the requests. The timeout is the amount of time that the program will wait for a response from the remote server before it fails. The default unit for the timeout value is seconds. You might append ``m'' or ``h'' to the timeout value to make it minutes or hours, respectively. The default timeout is '3m', i.e. 3 minutes.
- -i <time>
- Set the If-Modified-Since header in the request. If time is the name of a file, use the modification timestamp for this file. If time is not a file, it is parsed as a literal date. Take a look at HTTP::Date for recognized formats.
- -c <content-type>
-
Set the Content-Type for the request. This option is only allowed for
requests that take a content, i.e. POSTandPUT.You can force methods to take content by using the "-f" option together with "-c". The default Content-Type forPOSTis "application/x-www-form-urlencoded". The default Content-type for the others is "text/plain".
- -p <proxy-url>
- Set the proxy to be used for the requests. The program also loads proxy settings from the environment. You can disable this with the "-P" option.
- -P
- Don't load proxy settings from environment.
- -H <header>
-
Send this HTTPheader with each request. You can specify several, e.g.:
lwp-request \ -H 'Referer: other.url \ -H 'Host: somehost' \ this.url
- -C <username>:<password>
- Provide credentials for documents that are protected by Basic Authentication. If the document is protected and you did not specify the username and password with this option, then you will be prompted to provide these values.
The following options controls what is displayed by the program:
- -u
-
Print request method and absolute URLas requests are made.
- -U
-
Print request headers in addition to request method and absolute URL.
- -s
-
Print response status code. This option is always on for HEADrequests.
- -S
- Print response status chain. This shows redirect and authorization requests that are handled by the library.
- -e
-
Print response headers. This option is always on for HEADrequests.
- -E
- Print response status chain with full response headers.
- -d
- Do not print the content of the response.
- -o <format>
-
Process HTMLcontent in various ways before printing it. If the content type of the response is notHTML,then this option has no effect. The legal format values are; text, ps, links, html and dump.
If you specify the text format then the
HTMLwill be formatted as plain latin1 text. If you specify the ps format then it will be formatted as Postscript.The links format will output all links found in the
HTMLdocument. Relative links will be expanded to absolute ones.The html format will reformat the
HTMLcode and the dump format will just dump theHTMLsyntax tree.Note that the "HTML-Tree" distribution needs to be installed for this option to work. In addition the "HTML-Format" distribution needs to be installed for -o text or -o ps to work.
- -v
- Print the version number of the program and quit.
- -h
- Print usage message and quit.
- -a
- Set text(ascii) mode for content input and output. If this option is not used, content input and output is done in binary mode.
Because this program is implemented using the
LWP
library, it will
only support the protocols that LWP
supports.
