Class Method Detail
def self.new(io, boundary)Source
Create a new parser which parses io with multipart boundary boundary.
Instance Method Detail
def next(&block)Source
Parses the next form-data part and yields field name, io, FileMetadata
, and raw headers.
This method yields once instead of returning the values, because the IO object yielded to the block is only valid while the block is executing. The IO object will be closed as soon as the block returns. To store the content of the body part for longer than the block, the IO must be read into memory.
form_data = "--aA40\r\nContent-Disposition: form-data; name=\"field1\"; filename=\"foo.txt\"; size=13\r\nContent-Type: text/plain\r\n\r\nfield data\r\n--aA40--" parser = HTTP::FormData::Parser.new(IO::Memory.new(form_data), "aA40") parser.next do |part| part.name # => "field1" part.io.gets_to_end # => "field data" part.filename # => "foo.txt" part.size # => 13 part.headers["Content-Type"] # => "text/plain" end
