Overview

Response class for Unprocessable Entity responses (status code 422).

The request was well-formed but had semantic errors.

This class also includes (indirectly) module HTTPHeader, which gives access to its methods for getting headers.

Instance Attribute Summary

HTTPResponse - Inherited

#body

Returns the string response body; note that repeated calls for the unmodified body return a cached string:

#body=

Sets the body of the response to the given value.

#body_encoding

Returns the value set by body_encoding=, or false if none; see #body_encoding=.

#body_encoding=

Sets the encoding that should be used when reading the body:

#code

The HTTP result code string.

#decode_content

Set to true automatically when the request did not contain an Accept-Encoding header from the user.

#http_version

The HTTP version supported by the server.

#ignore_eof

Whether to ignore EOF when reading bodies with a specified Content-Length header.

#message

The HTTP result message sent by the server.

#uri

The URI used to fetch this response.

#entity
#msg
#uri=

HTTPHeader - Included

#chunked?

Returns true if field 'Transfer-Encoding' exists and has value 'chunked', false otherwise; see Transfer-Encoding response header:

#connection_close?

Returns whether the HTTP session is to be closed.

#connection_keep_alive?

Returns whether the HTTP session is to be kept alive.

#content_length

Returns the value of field 'Content-Length' as an integer, or nil if there is no such field; see Content-Length request header:

#content_length=

Sets the value of field 'Content-Length' to the given numeric; see Content-Length response header:

Instance Method Summary

HTTPResponse - Inherited

#inspect,
#read_body

Gets the entity body returned by the remote HTTP server.

#value

Raises an HTTP error if the response is not 2xx (success).

#extracting_encodings_from_meta_elements, #get_attribute, #procdest, #read_body_0, #stream_check,
#code_type

response <-> exception relationship.

#error!, #error_type, #header, #read_header,
#reading_body

body.

#response

header (for backward compatibility only; DO NOT USE).

#check_bom, #detect_encoding,
#inflater

Checks for a supported Content-Encoding header and yields an Inflate wrapper for this response’s socket when zlib is present.

#read_chunked

read_chunked reads from @socket for chunk-size, chunk-extension, CRLF, etc.

#scanning_meta, #sniff_encoding

HTTPHeader - Included

#[]

Returns the string field value for the case-insensitive field key, or nil if there is no such key; see Fields:

#[]=

Sets the value for the case-insensitive key to val, overwriting the previous value if the field exists; see Fields:

#add_field

Adds value val to the value array for field key if the field exists; creates the field with the given key and val if it does not exist.

#basic_auth

Sets header 'Authorization' using the given account and password strings:

#canonical_each
#content_range

Returns a Range object representing the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:

#content_type

Returns the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

#content_type=
#delete

Removes the header for the given case-insensitive key (see Fields); returns the deleted value, or nil if no such field exists:

#each
#each_capitalized

Like #each_header, but the keys are returned in capitalized form.

#each_capitalized_name

Calls the block with each capitalized field name:

#each_header

Calls the block with each key/value pair:

#each_key
#each_name

Calls the block with each field key:

#each_value

Calls the block with each string field value:

#fetch

With a block, returns the string value for key if it exists; otherwise returns the value of the block; ignores the default_val; see Fields:

#form_data=
#get_fields

Returns the array field value for the given key, or nil if there is no such field; see Fields:

#key?

Returns true if the field for the case-insensitive key exists, false otherwise:

#main_type

Returns the leading (‘type’) part of the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

#proxy_basic_auth

Sets header 'Proxy-Authorization' using the given account and password strings:

#range

Returns an array of Range objects that represent the value of field 'Range', or nil if there is no such field; see Range request header:

#range=
#range_length

Returns the integer representing length of the value of field 'Content-Range', or nil if no such field exists; see Content-Range response header:

#set_content_type

Sets the value of field 'Content-Type'; returns the new value; see Content-Type request header:

#set_form

Stores form data to be used in a POST or PUT request.

#set_form_data

Sets the request body to a URL-encoded string derived from argument params, and sets request header field 'Content-Type' to 'application/x-www-form-urlencoded'.

#set_range

Sets the value for field 'Range'; see Range request header:

#sub_type

Returns the trailing (‘subtype’) part of the media type from the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

#to_hash

Returns a hash of the key/value pairs:

#type_params

Returns the trailing (‘parameters’) part of the value of field 'Content-Type', or nil if no such field exists; see Content-Type response header:

#append_field_value, #basic_encode, #capitalize, #set_field, #initialize_http_header,
#length

Alias for HTTPHeader#size.

#size

obsolete.
