NAME
lwp-request, GET, HEAD, POST - Simple WWW user agent
SYNOPSIS
lwp-request [-aeEdvhx] [-m method] [-b <base URL>] [-t
<timeout>]
[-i <if-modified-since>] [-c <content-type>]
[-C <credentials>]
[-p <proxy-url>] [-o <format>] <url>...
DESCRIPTION
This program can be used to send requests to WWW 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 URI will be used as the base URI for 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 time
out is '3m', i.e. 3 minutes. - -i <time>
- Set the If-Modified-Since header in the request. If
time it 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 recogniced formats. - -c <content-type>
- Set the Content-Type for the request. This option is
only allowed for requests that take a content, i.e.
POST and PUT. You can force methods to take content
by using the "-f" option together with "-c". The
default Content-Type for POST is "applica
tion/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 pro
gram also loads proxy settings from the environment.
You can disable this with the "-P" option. - -H <header>
- Send this HTTP header with each request. You can spec
ify several, e.g.:
lwp-request -H 'Referer:http://other.url/' -H 'Host: somehost'http://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 URL as 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 HEAD requests.
- -S Print response status chain. This shows redirect and
- autorization requests that are handled by the library.
- -e Print response headers. This option is always on for
- HEAD requests.
- -d Do not print the content of the response.
- -o <format>
- Process HTML content in various ways before printing
it. If the content type of the response is not HTML,
then this option has no effect. The legal format val
ues are; text, ps, links, html and dump. - If you specify the text format then the HTML will 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
HTML document. Relative links will be expanded to
absolute ones. - The html format will reformat the HTML code and the
dump format will just dump the HTML syntax tree. - -v Print the version number of the program and quit.
- -h Print usage message and quit.
- -x Extra debugging output.
- -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.
