1. 基本 get 请求:

$http = new Http(); // 实例化对象

$result = $http->get('http://www.xxx.com/comment');

2. 基本 post 请求:

$http = new Http(); // 实例化对象

$result = $http->post('http://www.xxx.com/post-new-article', array('title'=>$title, 'body'=>$body) );

3. 模拟登录 ( post 和 get 同时使用, 利用 cookie 存储状态 ) :

$http = new Http(); // 实例化对象

$http->setCookiepath(substr(md5($username), 0, 10)); // 设置 cookie, 如果是多个用户请求的话

// 提交 post 数据

$loginData = $http->post('http://www.xxx.com/sso/login.php?client=ssologin.js(v1.3.19)', array('username'=>$username, 'loginPass'=>$password) );

$result = $http->get('http://weibo.com/at/comment');

4. 利用 initialize 函数设置多个 config 信息

$httpConfig['method'] = 'GET';

$httpConfig['target'] = 'http://www.wdphp.com.com/index.html';

$httpConfig['referrer'] = 'http://www.wdphp.com.com';

$httpConfig['user_agent'] = 'My Crawler';

$httpConfig['timeout'] = '30';

$httpConfig['params'] = array('var1' => 'testvalue', 'var2' => 'somevalue');

$http = new Http();

$http->initialize($httpConfig);

$result = $http->result;

5. 复杂的设置:

$http = new Http();

$http->useCurl(false); // 不使用 curl

$http->setMethod('POST'); // 使用 POST method

// 设置 POST 数据

$http->addParam('user_name' , 'yourusername');

$http->addParam('password' , 'yourpassword');

// Referrer

$http->setReferrer('https://www.xxx.com/login');

// 开始执行请求

$http->execute('https://www.xxx.com/login/authenticate');

$result = $http->getResult();

6. 获取开启了 basic auth 的请求

$http = new Http();

// Set HTTP basic authentication realms

$http->setAuth('yourusername', 'yourpassword');

// 获取某个被保护的应用的 feed

$http->get('http://www.wdphp.com/protected/feed.xml');

$result = $http->result;
