Http Client ⋅ Responses
HttpClient::request()
returns a Promise
that resolves to an instance of Response
as soon as the response headers are successfully received.
Response
objects are mutable (instead of immutable as in Artax v3 / PSR-7)
Response Status
You can retrieve the response’s HTTP status using getStatus()
. It returns the status as an integer. The optional (and possibly empty) reason associated with the status can be retrieved using getReason()
.
$response = yield $client->request($request);
var_dump($response->getStatus(), $response->getReason());
Response Protocol Version
You can retrieve the response’s HTTP protocol version using getProtocolVersion()
.
$response = yield $client->request($request);
var_dump($response->getProtocolVersion());
Response Headers
Response headers can be accessed by a set of methods.
hasHeader(string)
returns whether a given header is present.getHeader(string)
returns the first header with the given name ornull
if no such header is present.getHeaderArray(string)
returns all headers with the given name, possibly an empty array.getHeaders()
returns all headers as an associative array, see below.
getHeaders()
Format
[
"header-1" => [
"value-1",
"value-2",
],
"header-2" => [
"value-1",
],
]
Response Body
getBody()
returns a Payload
, which allows simple buffering and streaming access.
chunk = yield $response->getBody()->read();
reads only a single chunk from the body while$contents = yield $response->getBody()->buffer()
buffers the complete body. Please refer to thePayload
documentation for more information.
Request, Original Request and Previous Response
getRequest()
allows access to the request corresponding to the response. This might not be the original request in case of redirects. getOriginalRequest()
returns the original request sent by the client. This might not be the same request that was passed to Client::request()
, because the client might normalize headers or assign cookies. getPreviousResponse
allows access to previous responses in case of redirects, but the response bodies of these responses won’t be available, as they’re discarded. If you need access to these, you need to disable auto redirects and implement them yourself.
