一、正常 curl 获取响应结果

1)、curl请求代码

$url = 'http:://www.baidu.com'; 
$data = ['param' => 'test']; 
$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array("content-type:application/json")); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data)); 
$response = curl_exec($ch);  // 获取响应内容 
curl_close($ch); 

2）、curl_getinfo() 获取响应详情

... 
$response = curl_exec($ch);  // 获取响应内容 
$info = curl_getinfo($ch); 
$error = curl_error($ch); curl_close($ch); 

二、获取发送的请求 header 信息

1）、代码

curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE); $response = curl_exec($ch); 
$info = curl_getinfo($ch); 
$error = curl_error($ch); curl_close($ch);
