PHP模拟post提交数据方法汇总_PHP教程

使用php模拟post传值虽然在日常生活中用到的不是很多，但是在某些场合还是经常用到的。下面服务器之家小编给大家整理了三种php模拟post传值的方法，file_get_contents、curl和socket。

第一种：file_get_contents来模拟post

									<php

									function file_get_contents_post($url, $post){

									$options = array(

									‘http‘=> array(

									‘method‘=>‘POST‘,

									‘content‘=> http_build_query($post),

									),

									);

									$result = file_get_contents($url,false, stream_context_create($options));

									return $result;

									}

									$data = file_get_contents_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));

									var_dump($data);

第二种：curl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("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));

									var_dump($data);

第三种：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

									<span class="Apple-tab-span" style="white-space:pre"></span>POST {$urls[‘path‘]} HTTP/1.1

									<span class="Apple-tab-span" style="white-space:pre"></span>Host:{$urls[‘host‘]}

									<span class="Apple-tab-span" style="white-space:pre"></span>Content-Type: application/x-www-form-urlencoded

									<span class="Apple-tab-span" style="white-space:pre"></span>Content-Length:{$length}

									<span class="Apple-tab-span" style="white-space:pre"></span>Connection: close

									<span class="Apple-tab-span" style="white-space:pre"></span>{$post}

									<span class="Apple-tab-span" style="white-space:pre"></span>HEADER;

									fwrite($fp, $header);

									$result =‘‘;

									while(!feof($fp)){

									$result .= fread($fp,512);

									}

									$result = explode("\r\n\r\n", $result,2);

									return $result[1];

									}

									$data = socket_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));

									var_dump($data);

上面这三种方法最后看到的内容都是一样的，都可以得到post的传值；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。

下面给大家说下php模拟post提交请求，调用接口

									/**

									* 模拟post进行url请求

									* @param string $url

									* @param string $param

									*/

									function request_post($url = '', $param = '') {

									if (empty($url) || empty($param)) {

									return false;

									}

									$postUrl = $url;

									$curlPost = $param;

									$ch = curl_init();//初始化curl

									curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页

									curl_setopt($ch, CURLOPT_HEADER, 0);//设置header

									curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上

									curl_setopt($ch, CURLOPT_POST, 1);//post提交方式

									curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);

									$data = curl_exec($ch);//运行curl

									curl_close($ch);

									return $data;

									}

这是方法，

下面是具体的调用案例。

									function testAction(){

									$url = 'http://mobile.jschina.com.cn/jschina/register.php';

									$post_data['appid'] = '10';

									$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';

									$post_data['member_name'] = 'zsjs123';

									$post_data['password'] = '123456';

									$post_data['email'] = 'zsjs123@126.com';

									$o = "";

									foreach ( $post_data as $k => $v ) 

									{ 

									$o.= "$k=" . urlencode( $v ). "&" ;

									}

									$post_data = substr($o,0,-1);

									$res = $this->request_post($url, $post_data); 

									print_r($res);

									}

这样就提交请求，并且获取请求结果了。一般返回的结果是json格式的。

这里的post是拼接出来的。

也可以改造成下面的方式。

									/**

									* 模拟post进行url请求

									* @param string $url

									* @param array $post_data

									*/

									function request_post($url = '', $post_data = array()) {

									if (empty($url) || empty($post_data)) {

									return false;

									}

									$o = "";

									foreach ( $post_data as $k => $v ) 

									{ 

									$o.= "$k=" . urlencode( $v ). "&" ;

									}

									$post_data = substr($o,0,-1);

									$postUrl = $url;

									$curlPost = $post_data;

									$ch = curl_init();//初始化curl

									curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页

									curl_setopt($ch, CURLOPT_HEADER, 0);//设置header

									curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上

									curl_setopt($ch, CURLOPT_POST, 1);//post提交方式

									curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);

									$data = curl_exec($ch);//运行curl

									curl_close($ch);

									return $data;

									}

将拼接也封装了起来，这样调用的时候就更简洁了。

									function testAction(){

									$url = 'http://mobile.jschina.com.cn/jschina/register.php';

									$post_data['appid'] = '10';

									$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';

									$post_data['member_name'] = 'zsjs124';

									$post_data['password'] = '123456';

									$post_data['email'] = 'zsjs124@126.com';

									//$post_data = array();

									$res = $this->request_post($url, $post_data); 

									print_r($res);

									}
