php通过curl实现的POST和GET请求

下面是php通过curl实现的POST和GET请求，供大家参考

POST请求

/**
* curl模拟post请求，使用json格式
* @param $url
* @param $param
* @return mixed
*/
public static function curlPost($url, $param){
Log::info($url);
Log::info($param);
$param  = json_encode($param);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $param);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json; charset=utf-8',
'Content-Length: ' . strlen($param))
);
$output = curl_exec($ch);
Log::info($output);
curl_close($ch);
return $output;
}

Get请求

/**
* curl模拟get请求，使用json格式
* $param, $url
* return json
*/
public static function curlGet($url){
Log::info($url);
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);
curl_close($ch);
Log::info($output);
return $output;
}
