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:

        $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;
        }

android端:

        //tmpFile是上传的文件, key是我需要更新的文件名,qiniuUploadToken是获取到的上传凭证
        UploadManager uploadManager = new UploadManager();
        uploadManager.put(tmpFile, key, qiniuUploadToken, new UpCompletionHandler() {
            @Override
            public void complete(String key, ResponseInfo info, JSONObject response) {
                try {
                    if(response!=null){
                        final String actualKey=response.getString("key");
                        Log.d(TAG, "get server side key = "+actualKey);
                        }, new Response.ErrorListener() {
                            @Override
                            public void onErrorResponse(VolleyError error) {    }
                        });

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。
