PHP模拟post提交数据方法汇总

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。下面网页设计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

<phpfunction 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

<phpfunction 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

<phpfunction 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("", $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curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页curl_setopt($ch, CURLOPT_HEADER, 0);//设置headercurl_setopt($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($ch);//运行curlcurl_close($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curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页curl_setopt($ch, CURLOPT_HEADER, 0);//设置headercurl_setopt($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($ch);//运行curlcurl_close($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);}
