phppost提交数据

PHP模拟post提交数据方法汇总，phppost提交汇总

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。下面帮客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);
}
