我希望通过设置key为bucket:key的方式来获取可用于更新的文件token，但是用以下代码获取的token返回到android客户端后（客户端安卓，服务器端PHP，客户端先向服务器获取up token，然后凭token上传具体文件），新上传的图片没有覆盖原图。请问是哪儿有问题了呢？
php端：

<code>        $bucket = "phpsdk";
        $accessKey = QINIU_ACCESS_KEY;
        $secretKey = QINIU_SECRET_KEY;
        Qiniu_SetKeys($accessKey, $secretKey);
        $key=$this->input->post("file_key");
        if($key!=""){
            $putPolicy = new Qiniu_RS_PutPolicy($bucket.":".$key);
            $upToken = $putPolicy->Token(null);
            echo $upToken;
        }
</code>

android端：

            @Override
            public void complete(String key, ResponseInfo info, JSONObject response) {
                try {

这个有可能是cdn缓存导致的覆盖上传后，访问到的文件仍然是旧的资源，你可以通过url?v=20150309对资源进行访问，如果是访问到的最新的资源，说明资源覆盖成功了；一般资源的缓存刷新时间是10min开始刷新，24h全网刷新，如果你对资源更新的实时性要求比较高，你可以在空间设置的高级设置中刷新下资源的url，另外也可以采用资源url加上查询参数的方式去访问资源。
