Question

我的卷曲中有这个代码： $ data_string = json_encode（$ data）;

$ch = curl_init($url);                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);                                                       
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json; charset=utf-8',
    'User-Agent: '.$_SERVER['HTTP_USER_AGENT'],
    'X-Forwarded-For: '.$this->getIp()
));      

$result = curl_exec($ch);
return $result;

我得到了这个圆滑的结果：

我期待一个图片文件。

问题是我如何下载此图像文件？

Answer 1

您可以使用此代码

$profile_Image = $url; //image url
$userImage = 'myimg.jpg'; // renaming image
$path = '';  // your saving path
$ch = curl_init($profile_Image);
$fp = fopen($path . $userImage, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
$result = curl_exec($ch);
curl_close($ch);
fclose($fp);

Answer 2

你可以试试这个：

$data=send_curl($url);
$path='./test.jpg';
$file = file_put_contents($path,$data);

send_curl的功能

function send_curl($url, $data, $PROXY = "") {
  $ch = curl_init ();
  if ($PROXY != "") {
    curl_setopt ( $ch, CURLOPT_PROXY, $PROXY );
  }
  curl_setopt ( $ch, CURLOPT_URL, $url );
  curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
  curl_setopt ( $ch, CURLOPT_POST, 1 );
  curl_setopt ( $ch, CURLOPT_POSTFIELDS, $data );
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
  $result = curl_exec ( $ch );
  curl_close ( $ch );
  return $result;
}

Answer 3

理想情况下，浏览器决定如何使用Content-Type HTTP标头的信息显示给定的内容，PHP可以使用header()函数生成HTTP标头。

如果您确定您的照片将始终采用JPEG格式，则相当简单：

header('Content-Type: image/jpeg');
echo your_download_function();
exit;

否则，您需要获取远程服务器返回的标头。 Curl有一个棘手的语法 - 我引用你PHP cURL retrieving response headers AND body in a single request?
