Overview

The HTTPHeader module defines methods for reading and writing HTTP headers.

It is used as a mixin by other classes, to provide hash-like access to HTTP header values. Unlike raw hash access, HTTPHeader provides access via case-insensitive keys. It also provides methods for accessing commonly-used HTTP header values in more convenient formats.

#set_form(params, enctype = 'application/x-www-form-urlencoded', formopt = {})

Set an HTML form data set. params is the form data set; it is an Array of Arrays or a Hash +enctype is the type to encode the form data set. It is application/x-www-form-urlencoded or multipart/form-data. formopt is an optional hash to specify the detail.

boundary: the boundary of the multipart message
charset: the charset of the message. All names and the values of non-file fields are encoded as the charset.

Each item of params is an array and contains following items:

name: the name of the field
value: the value of the field, it should be a String or a File
opt: an optional hash to specify additional information

Each item is a file field or a normal field. If value is a File object or the opt have a filename key, the item is treated as a file field.

If Transfer-Encoding is set as chunked, this send the request in chunked encoding. Because chunked encoding is HTTP/1.1 feature, you must confirm the server to support HTTP/1.1 before sending it.

Example: http.set_form([[“q”, “ruby”], [“lang”, “en”]])

#set_form_data(params, sep = '&') Also known as: #form_data=
