Process:
This class is not exported from the 'electron'
module. It is only available as a return value of other methods in the Electron API.
IncomingMessage
implements the Readable Stream
interface and is therefore an .
Event: ‘data’
Returns:
chunk
Buffer - 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. Must be placed before ‘data’ event.
Event: ‘aborted’
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.headers
A Record<string, string | string[]>
representing the HTTP response headers. The headers
object is
formatted as follows:
- All header names are lowercased.
- Duplicates of
age
,authorization
,content-length
,content-type
,etag
,expires
,from
,host
,if-modified-since
,if-unmodified-since
,last-modified
,location
, ,proxy-authorization
,referer
,retry-after
,server
, oruser-agent
are discarded. set-cookie
is always an array. Duplicates are added to the array.- For all other headers, the values are joined together with ‘, ‘.
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.
response.rawHeaders
A containing the raw HTTP response headers exactly as they were received. The keys and values are in the same list. It is not a list of tuples. So, the even-numbered offsets are key values, and the odd-numbered offsets are the associated values. Header names are not lowercased, and duplicates are not merged.
