CGI::Test::Input - Abstract representation of POST input
# Deferred class, only heirs can be created # $input holds a CGI::Test::Input object $input->add_widget($w); # done internally for you $input->add_field("name", "value"); # manual input construction $input->add_file("name", "path"); # deferred reading $input->add_file_now("name", "/tmp/path"); # read file immediately syswrite INPUT, $input->data, $input->length; # if you really have to # $test is a CGI::Test object $test->POST("http://server:70/cgi-bin/script", $input);
The "CGI::Test::Input" class is deferred. It is an abstract representation of HTTP POST request input, as expected by the "POST" routine of "CGI::Test". Unless you wish to issue a "POST" request manually to provide carefully crafted input, you do not need to learn the interface of this hierarchy, nor even bother knowing about it. Otherwise, you need to decide which MIME encoding you want, and create an object of the appropriate type. Note that file uploading requires the use of the "multipart/form-data" encoding: MIME Encoding Type to Create --------------------------------- --------------------------- application/x-www-form-urlencoded CGI::Test::Input::URL multipart/form-data CGI::Test::Input::Multipart Once the object is created, you will be able to add name/value tuples corresponding to the CGI parameters to submit. For instance: my $input = CGI::Test::Input::Multipart->new(); $input->add_field("login", "ram"); $input->add_field("password", "foobar"); $input->add_file("organization", "/etc/news/organization"); Then, to inspect what is normally sent to the HTTP server: print "Content-Type: ", $input->mime_type, "\015\012"; print "Content-Length: ", $input->length, "\015\012"; print "\015\012"; print $input->data; But usually you'll hand out the $input object to the "POST" routine of "CGI::Test".
Creation Routine It is called "new" as usual. All subclasses have the same creation routine signature, which takes no parameter. Adding Parameters CGI parameter are name/value tuples. In case of file uploads, they can have a content as well, the value being the file path on the client machine. "add_field" name, value Adds the CGI parameter name, whose value is value. add_file name, path Adds the file upload parameter name, located at path. The file is not read immediately, so it must remain available until the data routine is called, at least. It is not an error if the file cannot be read at that time. When not using the "multipart/form-data" encoding, only the name/path tuple will be transmitted to the script. add_file_now name, path Same as "add_file", but the file is immediately read and can therefore be disposed of afterwards. However, the file must exist. add_widget widget Add any widget, i.e. a "CGI::Test::Form::Widget" object. This routine is called internally by "CGI::Test" to construct the input data when submiting a form via POST. Generation "data" Returns the data, under the proper encoding. "mime_type" Returns the proper MIME encoding type, suitable for inclusion within a Content-Type header. "length" Returns the data length.
