* Main interface for HTTP requests
*
* This method initiates a request and sends it via a transport before
* parsing.
*
* The `$options` parameter takes an associative array with the following
* options:
*
* - `timeout`: How long should we wait for a response?
* Note: for cURL, a minimum of 1 second applies, as DNS resolution
* operates at second-resolution only.
* (float, seconds with a millisecond precision, default: 10, example: 0.01)
* - `connect_timeout`: How long should we wait while trying to connect?
* (float, seconds with a millisecond precision, default: 10, example: 0.01)
* - `useragent`: Useragent to send to the server
* (string, default: php-requests/$version)
* - `follow_redirects`: Should we follow 3xx redirects?
* (boolean, default: true)
* - `redirects`: How many times should we redirect before erroring?
* (integer, default: 10)
* - `blocking`: Should we block processing on this request?
* (boolean, default: true)
* - `filename`: File to stream the body to instead.
* (string|boolean, default: false)
* - `auth`: Authentication handler or array of user/password details to use
* for Basic authentication
* (\WpOrg\Requests\Auth|array|boolean, default: false)
* - `proxy`: Proxy details to use for proxy by-passing and authentication
* (\WpOrg\Requests\Proxy|array|string|boolean, default: false)
* - `max_bytes`: Limit for the response body size.
* (integer|boolean, default: false)
* - `idn`: Enable IDN parsing
* (boolean, default: true)
* - `transport`: Custom transport. Either a class name, or a
* transport object. Defaults to the first working transport from
* {@see \WpOrg\Requests\Requests::getTransport()}
* (string|\WpOrg\Requests\Transport, default: {@see \WpOrg\Requests\Requests::getTransport()})
* - `hooks`: Hooks handler.
* (\WpOrg\Requests\HookManager, default: new WpOrg\Requests\Hooks())
* - `verify`: Should we verify SSL certificates? Allows passing in a custom
* certificate file as a string. (Using true uses the system-wide root
* certificate store instead, but this may have different behaviour
* across transports.)
* (string|boolean, default: certificates/cacert.pem)
* - `verifyname`: Should we verify the common name in the SSL certificate?
* (boolean, default: true)
* - `data_format`: How should we send the `$data` parameter?
* (string, one of 'query' or 'body', default: 'query' for
* HEAD/GET/DELETE, 'body' for POST/PUT/OPTIONS/PATCH)
*

* @param array $headers Extra headers to send with the request

* `multiple.request.complete` callback.
*
* The request fields value is an associative array with the following keys:
*
* - `url`: Request URL Same as the `$url` parameter to
* {@see \WpOrg\Requests\Requests::request()}
* (string, required)
* - `headers`: Associative array of header fields. Same as the `$headers`
* parameter to {@see \WpOrg\Requests\Requests::request()}
* (array, default: `array()`)
* - `data`: Associative array of data fields or a string. Same as the
* `$data` parameter to {@see \WpOrg\Requests\Requests::request()}
* (array|string, default: `array()`)
* - `type`: HTTP request type (use \WpOrg\Requests\Requests constants). Same as the `$type`
* parameter to {@see \WpOrg\Requests\Requests::request()}
* (string, default: `\WpOrg\Requests\Requests::GET`)
* - `cookies`: Associative array of cookie name to value, or cookie jar.
* (array|\WpOrg\Requests\Cookie\Jar)
*
* If the `$options` parameter is specified, individual requests will
* inherit options from it. This can be used to use a single hooking system,
* or set all the types to `\WpOrg\Requests\Requests::POST`, for example.
*
* In addition, the `$options` parameter takes the following global options:
*
* - `complete`: A callback for when a request is complete. Takes two
* parameters, a \WpOrg\Requests\Response/\WpOrg\Requests\Exception reference, and the
* ID from the request array (Note: this can also be overridden on a
* per-request basis, although that's a little silly)
* (callback)

* @throws \WpOrg\Requests\Exception\InvalidArgument When the passed $requests argument is not an array or iterable object with array access.
