Summary of PHP simulated post submission data methods, summary of phppost submission

Using PHP to simulate post value transfer is not used much in daily life, but it is still common in some occasions. used. Below, the editor of Bangkejia has compiled three methods for php to simulate post value transfer, file_get_contents, curl and socket.

The first one: file_get_contents to simulate 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);

Second type: curl simulation 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);

Third method: socket to simulate 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);

The last content you see in the above three methods is the same, and you can get the value of post; but when using socket, you must pay attention to the complete information of the header when sending header information, such as content type and The content length must be present, and there must be a blank line between connection: close and post data, etc.; the content obtained through the socket contains header information, which needs to be processed to obtain the real content.

Let me tell you how to simulate post submission request in PHP and call the interface

/**
* 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;
} 

This is the method,

The following is a specific call case.

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);
} 

In this way, the request is submitted and the request result is obtained. Generally, the returned results are in json format.

The posts here are spliced ​​together.

It can also be transformed into the following method.

/**
* 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;
}

The splicing is also encapsulated, so that it is simpler to call.

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);
}
