用cordova插件saveImageUrl保存七牛圖片水印，導致保存失敗，請問有沒有解決辦法,會彈出圖片保存成功，但其實無法在相簿中找到圖片

      window.saveImage.fromUrl(
          $scope.zoomImage+'?watermark/1/image/aHR0cHM6Ly9vbGh2a2RzNzMucW5zc2wuY29tL2xvZ28ucG5n/dissolve/50/gravity/SouthEast/dx/20/dy/20',
            function (msg) {
                widget.msgToast('图片保存成功');
            },
            function (err) {
                widget.msgToast('图片保存失败');
            },
            type
        );
