Google云端硬盘下载具有相同内容的文件

Question

我正在尝试从Google驱动器中选择两个图像，并尝试如图所示在base64中下载内容，并将其发送到服务器端以将文件下载到我的服务器文件夹中，但是下载后我可以这两个文件但内容相同。我不确定我在哪里做错了。有人可以解决我这个问题吗？

对于单个图像，它可以正常工作。问题是当我选择多个文件时。 有时选择了2个文件，一个文件被下载，另一些则没有，有时出现403错误。.apiv3在Google上没有问题文档。

 "error": {
    "errors": [
        {

            "reason": "dailyLimitExceeded",
            "message": "Daily Limit Exceeded"
        }
    ],
        "code": 403,
            "message": "Daily Limit Exceeded"
}

获取数据的代码：

 function pickerCallback(data) {
    var fileId;
    var gdriveids = [];
    var gdrivebas64 = [];
    var selectedfilenames=[];

    if (data.action == google.picker.Action.PICKED) {
        for (var i = 0; i < data.docs.length; i++) {
            fileId = data.docs[i].id;
            gapi.load('client', function () {
                gapi.client.load('drive', 'v3', function () {
                    var file = gapi.client.drive.files.get({ 'fileId': fileId, fields: '*' });
                    file.execute(function (resp) {
                        console.log(resp);
                        var maxFileSize = 20971520/*20MB(20*1024*1024)*/;
                        filesize = resp.size;
                        displayfilesize = formatBytes(filesize);
                        filesizes.push(displayfilesize);
                        morefiles = maxfiles - imgcount;
                        if (gdriveids.length > morefiles) {
                            $('#filelist').html("You can add only " + morefiles + " more file(s).");
                            $('#myProgress').show();
                        } else {
                            if (filesize < maxFileSize) {
                                $('#myProgress').show();
                                $('.images').html("");
