一、用file_get_contents来模拟post
- <?php
- function file_get_contents_post($url, $post) {
- $options = array(
- ‘http’ => array(
- ‘method’ => ‘POST’,
- // ‘content’ => ‘name=caiknife&email=caiknife@gmail.com’,
- ‘content’ => http_build_query($post),
- ),
- );
- $result = file_get_contents($url, false, stream_context_create($options));
- return $result;
- }
- $data = file_get_contents_post(“https://www.a.com/post/post.php”, array(‘name’=>‘caiknife’, ’email’=>‘caiknife@gmail.com’));
- var_dump($data);
二、用curl来模拟post
- <?php
- function curl_post($url, $post) {
- $options = array(
- CURLOPT_RETURNTRANSFER => true,
- CURLOPT_HEADER => false,
- CURLOPT_POST => true,
- CURLOPT_POSTFIELDS => $post,
- );
- $ch = curl_init($url);
- curl_setopt_array($ch, $options);
- $result = curl_exec($ch);
- curl_close($ch);
- return $result;
- }
- $data = curl_post(“https://www.a.com/post/post.php”, array(‘name’=>‘caiknife’, ’email’=>‘caiknife@gmail.com’));
- var_dump($data);
三、用socket来模拟post:
- <?php
- function socket_post($url, $post) {
- $urls = parse_url($url);
- if (!isset($urls[‘port’])) {
- $urls[‘port’] = 80;
- }
- $fp = fsockopen($urls[‘host’], $urls[‘port’], $errno, $errstr);
- if (!$fp) {
- echo “$errno, $errstr”;
- exit();
- }
- $post = http_build_query($post);
- $length = strlen($post);
- $header = <<<HEADER
- POST {$urls[‘path’]} HTTP/1.1
- Host: {$urls[‘host’]}
- Content-Type: application/x-www-form-urlencoded
- Content-Length: {$length}
- Connection: close
- {$post}
- HEADER;
- fwrite($fp, $header);
- $result = ”;
- while (!feof($fp)) {
- // receive the results of the request
- $result .= fread($fp, 512);
- }
- $result = explode(“rnrn”, $result, 2);
- return $result[1];
- }
- $data = socket_post(“https://www.a.com/post/post.php”, array(‘name’=>‘caiknife’, ’email’=>‘caiknife@gmail.com’));
- var_dump($data);
这三种方法最后看到的内容都是一样的,但是在是用socket的时候,发送header信息时必须要注意header的完整信息,比如content type和content length必须要有,connection: close和post数据之间要空一行,等等;而通过socket取得的内容是包含了header信息的,要处理一下才能获得真正的内容。
