php - PHP curl上传似乎只发送10个字节？

Question

curl 似乎只上传了 10 个字节。$url 正确，$file 路径也正确，文件存在！

我有这个代码：

curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);

    $post   = array(
        "id" => $id,
        "api_key" => $api_key,
        "file" => "@".$_SERVER['DOCUMENT_ROOT']."/".$file
        );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
    $response = curl_exec($ch);

如果 url 正确，则代码对我来说很好。您是否检查过 $file_path 是否有效并具有读取权限？
