false
Errors are never okay, even when the status code is in the 2xx success range.
headers
HttpHeaders
All response headers.

type
HttpEventType.ResponseHeader | HttpEventType.Response
Type of the response, narrowed to either the full response or the header.
redirected
boolean | undefined
Indicates whether the HTTP response was redirected during the request.
This property is only available when using the Fetch API using withFetch()
When using the default XHR Request this property will be undefined
responseType
ResponseType | undefined
Indicates the type of the HTTP response, based on how the request was made and how the browser handles the response.
This corresponds to the type
property of the Fetch API's Response
object, which can indicate values such as:
'basic'
: A same-origin response, allowing full access to the body and headers.'cors'
: A cross-origin response with CORS enabled, exposing only safe response headers.'opaque'
: A cross-origin response made withno-cors
, where the response body and headers are inaccessible.'opaqueredirect'
: A response resulting from a redirect followed inno-cors
mode.'error'
: A response representing a network error or similar failure.
This property is only available when using the Fetch-based backend (via withFetch()
).
When using Angular's (XHR) backend, this value will be undefined
.
Description
A response that represents an error or failure, either from a non-successful HTTP status, an error while executing the request, or some other failure which occurred during the parsing of the response.
Any error returned on the Observable
response stream will be
wrapped in an HttpErrorResponse
to provide additional context about
the state of the HTTP layer when the error occurred. The error property
will contain either a wrapped Error object or the error response returned
from the server.
