php模拟post行为代码总结
时间：2009-05-22 来源：hkebao
GET行为比较简单，POST比较复杂一些。
这里提供两种方法供选择：第一：手写代码
第二：利用HttpClient php类库
第一种方法：代码如下：
PHP代码- <？PHP
- $flag = 0;
- //要post的数据
- $argv = array(
- 'var1'=>'abc',
- 'var2'=>'你好吗');
- //构造要post的字符串
- foreach ($argv as $key=>$value) {
- if ($flag!=0) {
- $params .= "&";
- $flag = 1;
- }
- $params.= $key."="; $params.= urlencode($value);
- $flag = 1;
- }
- $length = strlen($params);
- //创建socket连接
- $fp = fsockopen("127.0.0.1",80,$errno,$errstr,10) or exit($errstr."--->".$errno);
- //构造post请求的头
- $header = "POST /mobile/try.php HTTP/1.1";
- $header .= "Host:127.0.0.1";
- $header .= "Referer:/mobile/sendpost.php";
- $header .= "Content-Type: application/x-www-form-urlencoded";
- $header .= "Content-Length: ".$length."";
- $header .= "Connection: Close";
- //添加post的字符串
- $header .= $params."";
- //发送post的数据
- fputs($fp,$header);
- $inheader = 1;
- while (!feof($fp)) {
- $line = fgets($fp,1024); //去除请求包的头只显示页面的返回数据
- if ($inheader && ($line == "\n" || $line == "")) {
- $inheader = 0;
- }
- if ($inheader == 0) {
- echo $line;
- }
- }
- fclose($fp);
- ?>
第二种方法是：使用httpclient类，代码如下
PHP代码- $pageContents = HttpClient::quickPost('http://example.com/someForm', array(
- 'name' => 'Some Name',
- 'email' => '[email protected]'
- ));
使用附件的类库，也可以去官方下载最新的类库，官方地址为：http://scripts.incutio.com/httpclient/index.php
附加一些点php httpclient的其他几个用法
静态方法获取网页：
PHP代码- $pageContents = HttpClient::quickGet('http://example.com/');
Get方法获取
PHP代码- $client = new HttpClient('example.com');
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
带调试的Get方法获取
PHP代码- $client = new HttpClient('example.com');
- $client->setDebug(true);
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
带自动转向的Get方法
PHP代码- $client = new HttpClient('www.amazon.com');
- $client->setDebug(true);
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
检查页面是否存在
PHP代码- $client = new HttpClient('example.com');
- $client->setDebug(true);
- if (!$client->get('/thispagedoesnotexist')) {
- die('An error occurred: '.$client->getError());
- }
- if ($client->getStatus() == '404') {
- echo 'Page does not exist!';
- }
- $pageContents = $client->getContent();
伪造客户端
PHP代码- $client = new HttpClient('example.com');
- $client->setDebug(true);
- $client->setUserAgent('Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3a) Gecko/20021207');
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
登录验证并请求一个网页
PHP代码- $client = new HttpClient('example.com');
- $client->post('/login.php', array(
- 'username' => 'Simon',
- 'password' => 'ducks'
- ));
- if (!$client->get('/private.php')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
HTTP授权
PHP代码- $client = new HttpClient('example.com');
- $client->setAuthorization('Username', 'Password');
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- $pageContents = $client->getContent();
输出头信息
PHP代码- $client = new HttpClient('example.com');
- if (!$client->get('/')) {
- die('An error occurred: '.$client->getError());
- }
- print_r($client->getHeaders());
设置一个域内重定向最多次数
PHP代码- $client = new HttpClient('www.amazon.com');
- $client->setDebug(true);
- $client->setMaxRedirects(3);
- $client->get('/');
