PHP 使用 curl 发送 post 请求，可以自定义header和传递参数

curl_get.php

/** 
* Send a GET requst using cURL 
* @param string $url to request 
* @param array $get values to send 
* @param array $options for cURL 
* @return string 
*/ 
function curl_get($url, array $get = NULL, array $options = array()) 
{    
    $defaults = array( 
        CURLOPT_URL => $url. (strpos($url, '?') === FALSE ? '?' : ''). http_build_query($get), 
        CURLOPT_HEADER => 0, 
        CURLOPT_RETURNTRANSFER => TRUE, 
        CURLOPT_TIMEOUT => 4 
    ); 
    
    $ch = curl_init(); 
    curl_setopt_array($ch, ($options + $defaults)); 
    if( ! $result = curl_exec($ch)) 
    { 
        trigger_error(curl_error($ch)); 
    } 
    curl_close($ch); 
    return $result; 
}

curl_post.php

function curl_post($url, array $params = NULL, array $headers = array())
{
	$defaults = array(
		CURLOPT_POST => 1,
		CURLOPT_HEADER => 0,
		CURLOPT_URL => $url,
		CURLOPT_FRESH_CONNECT => 1,
		CURLOPT_RETURNTRANSFER => 1,
		CURLOPT_FORBID_REUSE => 1,
		CURLOPT_TIMEOUT => 3,
		CURLOPT_POSTFIELDS => http_build_query($params),
		CURLOPT_HTTPHEADER => $headers
	);

	$ch = curl_init();
	curl_setopt_array($ch, $defaults);
	if( ! $result = curl_exec($ch))
	{
		trigger_error(curl_error($ch));
	}
	curl_close($ch);
	return $result;
}

curl_post_demo.php

$result = curl_post("post_url", [
  "key1" =>  "value1"
], array(
  'User-Agent: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3_3 like Mac OS X) AppleWebKit/603.3.8 (KHTML, like Gecko) Mobile/14G60 NetType/WIFI Language/en',
));
// $json 是返回的是数组
$json = json_decode($result,true);
