        $path = $_SERVER['DOCUMENT_ROOT'];

        $tmpfile = $_FILES['fname']['tmp_name'];
        $tmpType = $_FILES['fname']['type'];
        upload_file($url,$tmpname,$tmpfile,$tmpType);
        exit;
    }
    echo '<form action="" enctype="multipart/form-data"  method="post">
    <input type="file" name="fname" /》
    <input type="submit" value="Submit" />
    </form>';
?>

There is no error message on the page, and when I open Weibo’s API, it shows a 405 error. I don’t know if it’s the API itself.

If the version of php is 5.5 or above
You cannot use @+file path when uploading files with curl.
Use CURLFile instead, even curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false); is useless

Set up the protocol and give it a try! header("Content-Type:multipart/form-data")
