提供了一种简单的方式与Web服务交互（目前使用file_get_contents()）。轻松跟踪交换的Cookies，便于抓取。以下是一个Thirdlane示例。

安装

cd <project_dir>
composer require aicial\webrequest

用法

require __DIR__ . '/vendor/autoload.php';	//Use composers autoload

$webRequest = new Aicial\Webrequest\Webrequest();
$webRequest->setURL('https://YOUR_SERVICE.TLD/');
$webRequest->setJSON(true);

$serverResponse = $webRequest->go();

var_dump($serverResponse);

方法

go()			//Perform the web request
setCookies()	//Set any cookies to be included in the headers
setHeaders()	//Set any headers to be sent to the target URL
setJSON()		//Is this transaction sending / expecting JSON
setJSONPretty()	//Should JSON being sent be encoded in an easily readable format?
setMethod()		//Set the HTTP method GET, HEAD, PUT, POST are valid
setPost()		//Set post contents
setQuerystring()	//Set querystring data
setTrackCookies()	//Should cookies be tracked?
setURL()		//Set the target URL Must include http:// or https://
setVerifyPeer()   //Should SSL peers be verified?
setWebTimeout()   //Set's the value that determines how long we wait for a response

示例 - 使用Cookies

交换的Cookies跟踪在包内部处理。您只需要打开它，就可以与服务器进行简单的抓取交易。以下是从ThirdLane PBX服务器获取记录调用列表的示例

<?php
require __DIR__ . '/vendor/autoload.php';	//Use composers autoload

$webrequest = new Aicial\Webrequest\Webrequest();

$url = 'http://mypbx.server:10000';
$user = 'mytlusername';
$password = 'mytlpassword';

$loginUrl = 'session_login.cgi';
$recordedUrl = 'asterisk/recorded_calls.cgi';

$webrequest->setURL($url.'/'.$loginUrl);
$webrequest->setVerifyPeer(false);		//Most Thirdlane servers have invalid SSL
$webrequest->setTrackCookies(true);	//Return cookies received
$response = $webrequest->go();			//Make the initial GET request

$post = array('user' => $this->config['username'], 'pass' => $this->config['password'], 'page' => '/', 'save' => '1');
$webrequest->setMethod('POST');	//Use a form POST
$webrequest->setPost($post);	//Supply the POST data
$response = $webrequest->go();	//Notice the URL has not been set again - it is still set from before.

$webrequest->setURL($url.'/'.$recordedUrl);	//The URL for Recorded Calls Listing
$webrequest->setMethod('GET');		//Back to using HTTP GET
$webrequest->setPost();			//Clear the POST array
$response = $webrequest->go();	//Get the page data

print_r($response);	//Do what you want with the content

注意

尽管该包支持Cookies，但它不遵守域或过期（目前如此）。

发送服务器无法使Cookies过期（删除）。一些与服务器的交互需要此功能以进行权限提升。如果您的这种情况，目前唯一的解决方法是知道何时删除Cookies，并在代码中执行。
