Class: IncomingMessage
Handle responses to HTTP/HTTPS requests.
Process: Main
IncomingMessage implements the Readable Stream
interface and is therefore an EventEmitter.
Instance Events
Event: 'data'
Returns:
chunkBuffer - A chunk of response body's data.
The data event is the usual method of transferring response data into
applicative code.
Event: 'end'
Indicates that response body has ended.
Event: 'aborted'
Emitted when a request has been canceled during an ongoing HTTP transaction.
Event: 'error'
Returns:
error Error - Typically holds an error string identifying failure root cause.
Emitted when an error was encountered while streaming response data events. For
instance, if the server closes the underlying while the response is still
streaming, an error event will be emitted on the response object and a close
event will subsequently follow on the request object.
Instance Properties
An IncomingMessage instance has the following readable properties:
response.statusCode
An Integer indicating the HTTP response status code.
response.statusMessage
A String representing the HTTP status message.
response.headers
An Object representing the response HTTP headers. The headers object is
formatted as follows:
- All header names are lowercased.
- Each header name produces an array-valued property on the headers object.
- Each header value is pushed into the array associated with its header name.
response.httpVersion
A String indicating the HTTP protocol version number. Typical values are '1.0'
or '1.1'. Additionally httpVersionMajor and httpVersionMinor are two
Integer-valued readable properties that return respectively the HTTP major and
minor version numbers.
response.httpVersionMajor
An Integer indicating the HTTP protocol major version number.
response.httpVersionMinor
An Integer indicating the HTTP protocol minor version number.
