//代码是这样的，我要异步处理图片持久化 

function makeUrl($url,$bucket,$savekey,$ak="KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR",$sk="D-K57TE5hPe3krexftxLWFKmL2xbQEKA-mtkrUfB"){
    $find = array('+', '/');
    $replace = array('-', '_');
    $encode = str_replace($find,$replace,base64_encode("$bucket:$savekey"));
    $url    = $url."|saveas/".$encode;
    $sha1   = hash_hmac('sha1',$url,$sk,true);
    $sign   = $ak.":".(str_replace($find,$replace,base64_encode($sha1)));
    $data   = $url."/sign/".$sign;
    return $data;
}

echo makeUrl("gitwiduu.u.qiniudn.com/weidu.png?imageView/2/w/200/h/200","gitwiduu","widuu.png");

//输出url是

gitwiduu.u.qiniudn.com/weidu.png?imageView/2/w/200/h/200|saveas/Z2l0d2lkdXU6d2lkdXUucG5n/sign/KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR:oLnyNAFkj7gs6a0LyLJ581bCS_Q=

//然后拼接params

//bucket=gitwiduu&key=weidu.png&fops=imageView/2/w/200/h/200;saveas/Z2l0d2lkdXU6d2lkdXUucG5n/sign/KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR:oLnyNAFkj7gs6a0LyLJ581bCS_Q=&notifyURL=http://localhost/

function url_safe_baseencode($str) // URLSafeBase64Encode
{
    $find = array('+', '/');

//根据官方文档path?query\nbody 加密输出结果

//获取Authorization token
//输出 token 是 KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR:8nodNoJ7A8QE59UNrlMXSs-2ATY=
然后php curl 实验不行 然后在linux下实验

curl -d "bucket=gitwiduu&key=weidu.png&fops=imageView/2/w/200/h/200;saveas/Z2l0d2lkdXU6d2lkdXUucG5n/sign/KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR:oLnyNAFkj7gs6a0LyLJ581bCS_Q=&notifyURL=http://localhost/" -H  "Content-Type: application/x-www-form-urlencoded" -H "Authorization: QBox KUN6xYZlOAtid2MjHm90-6VFY2M7HC90ijDH4uOR:8nodNoJ7A8QE59UNrlMXSs-2ATY=" http://api.qiniu.com/pfop

//或者到 http://api.qiniu.com/pfop/ 都是返回json出现{"error":"bad token"}" 请问一下哪里出的错误呀
