Detailed Description

Class to handle multiple HTTP requests.

If curl is available, requests will be made concurrently. Otherwise, they will be made serially.

HTTP request maps are arrays that use the following format:

method : GET/HEAD/PUT/POST/DELETE
url : HTTP/HTTPS URL
query : <query parameter field/value associative array> (uses RFC 3986)
headers : <header name/value associative array>
body : source to get the HTTP request body from; this can simply be a string (always), a resource for PUT requests, and a field/value array for POST request; array bodies are encoded as multipart/form-data and strings use application/x-www-form-urlencoded (headers sent automatically)
stream : resource to stream the HTTP response body to
proxy : HTTP proxy to use
flags : map of boolean flags which supports:
- relayResponseHeaders : write out header via header() Request maps can use integer index 0 instead of 'method' and 1 instead of 'url'.

Since 1.35, callers should use HttpRequestFactory::createMultiClient() to get a client object with appropriately configured timeouts.

Since: 1.23

Constructor & Destructor Documentation

◆ __construct()

MultiHttpClient::__construct ( array $options )

Since 1.35, callers should use HttpRequestFactory::createMultiClient() to get a client object with appropriately configured timeouts instead of constructing a MultiHttpClient directly.

Parameters

array

$options

connTimeout : default connection timeout (seconds)
reqTimeout : default request timeout (seconds)
maxConnTimeout : maximum connection timeout (seconds)
maxReqTimeout : maximum request timeout (seconds)
proxy : HTTP proxy to use
usePipelining : whether to use HTTP pipelining if possible (for all hosts)
maxConnsPerHost : maximum number of concurrent connections (per host)
userAgent : The User-Agent header value to send
logger : a \Psr\Log\LoggerInterface instance for debug logging
caBundlePath : path to specific Certificate Authority bundle (if any)

◆ isCurlEnabled()

◆ normalizeRequests()

MultiHttpClient::normalizeRequests ( array & $reqs )

private

Parameters

◆ run()

MultiHttpClient::run	(	array	$req,
		array	$opts = `[]`
	)

Execute an HTTP(S) request.

This method returns a response map of:

code : HTTP response code or 0 if there was a serious error
reason : HTTP response reason (empty if there was a serious error)
headers : <header name/value associative array>
body : HTTP response body or resource (if "stream" was set)
error : Any error string The map also stores integer-indexed copies of these values. This lets callers do:
list( $rcode, $rdesc, $rhdrs, $rbody, $rerr ) = $http->run( $req );

Parameters

array $req HTTP request array

array $opts
connTimeout : connection timeout per request (seconds)
reqTimeout : post-connection timeout per request (seconds)
usePipelining : whether to use HTTP pipelining if possible (for all hosts)
maxConnsPerHost : maximum number of concurrent connections (per host)
Returns
array Response array for request

◆ runMulti()

MultiHttpClient::runMulti	(	array	$reqs,
		array	$opts = `[]`
	)

Execute a set of HTTP(S) requests.

If curl is available, requests will be made concurrently. Otherwise, they will be made serially.

The maps are returned by this method with the 'response' field set to a map of:

code : HTTP response code or 0 if there was a serious error
reason : HTTP response reason (empty if there was a serious error)
headers : <header name/value associative array>
body : HTTP response body or resource (if "stream" was set)
error : Any error string The map also stores integer-indexed copies of these values. This lets callers do:
list( $rcode, $rdesc, $rhdrs, $rbody, $rerr ) = $req['response'];

All headers in the 'headers' field are normalized to use lower case names. This is true for the request headers and the response headers. Integer-indexed method/URL entries will also be changed to use the corresponding string keys.

Parameters

array[]	$reqs	Map of HTTP request arrays
array	$opts	Options connTimeout : connection timeout per request (seconds) reqTimeout : post-connection timeout per request (seconds) usePipelining : whether to use HTTP pipelining if possible (for all hosts) maxConnsPerHost : maximum number of concurrent connections (per host)

Returns: array[] $reqs With response array populated for each
