关于PHP7的CURL上传文件

CULR 部分

$url = 'http://localhost/test/curlUploadFile/upload.php'; //处理上传的php文件，根据情况修改
$path='ftp.txt';    //文件路径
$curl = curl_init();
curl_setopt($curl,CURLOPT_SAFE_UPLOAD,true);
//$data = array('file' => '@' . realpath($path));//‘@' 符号告诉服务器为上传资源 php<=5.5   这个是php版本小于5.5的用法
$data = ['file'=>new CURLFile(realpath($path))]; //注意：这里的的 file 可以自定义
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_POST,);
curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,);
curl_setopt($curl,CURLOPT_USERAGENT,'test');
echo $res=curl_exec($curl);
echo $err = curl_error($curl);

upload.php部分：

$file = $_FILES;
file_put_contents(time().'.json',json_encode($_FILES));
$tmpname = $_FILES['file']['tmp_name'];
$name = $_FILES['file']['name'];
$res = move_uploaded_file($tmpname,'uploads/'.$name);

var_dump($res);
