Google apps script 如何使用应用程序脚本通过Docs加载项将文件添加到Google Drive？

这是我的设想。我为谷歌文档创建了一个附加组件，充当视频工具箱

我尝试添加的一个功能是使用内置的网络摄像头（使用videojs录像机）录制视频，然后在文档中链接到该视频。我已经完成了视频部分的工作，但不确定如何将webm JS Blob转换为Google Blob，以便我可以在用户Google Drive上创建一个用于共享和链接的文件

只是想弄清楚这是怎么回事，这是我到目前为止所做的，没有任何运气

客户端代码

//event handler for video recording finish   
vidrecorder.on('finishRecord', function()
{
    // the blob object contains the recorded data that
    // can be downloaded by the user, stored on server etc.
    console.log('finished recording: ', vidrecorder.recordedData);
    google.script.run.withSuccessHandler(function(){
        console.log("winning");
    }).saveBlob(vidrecorder.recordedData);
});

function saveBlob(blob) {
    Logger.log("Uploaded %s of type %s and size %s.",
            blob.name,
            blob.size, 
            blob.type);
}

服务器端代码

//event handler for video recording finish   
vidrecorder.on('finishRecord', function()
{
    // the blob object contains the recorded data that
    // can be downloaded by the user, stored on server etc.
    console.log('finished recording: ', vidrecorder.recordedData);
    google.script.run.withSuccessHandler(function(){
        console.log("winning");
    }).saveBlob(vidrecorder.recordedData);
});

function saveBlob(blob) {
    Logger.log("Uploaded %s of type %s and size %s.",
            blob.name,
            blob.size, 
            blob.type);
}

我得到的错误似乎与blob的序列化有关。但实际上，这些异常并不是很有用——只是指向一些最小化的代码

编辑：请注意，这里没有涉及表单对象，因此没有表单帖子，也没有文件上传对象，正如其他人所指出的那样，但是它有点不同，因为我们得到了一个Blob对象，需要将其保存到服务器。

感谢Zig Mandel和Steve Webster，他们从服务器提供了一些关于这方面的见解

我终于拼凑了足够的碎片来让它工作

客户端代码

        vidrecorder.on('finishRecord', function()
        {
            // the blob object contains the recorded data that
            // can be downloaded by the user, stored on server etc.
            console.log('finished recording: ', vidrecorder.recordedData.video);
            var blob = vidrecorder.recordedData.video;

            var reader = new window.FileReader();
            reader.readAsDataURL(blob);
            reader.onloadend = function() {
                b64Blob = reader.result;
                 google.script.run.withSuccessHandler(function(state){
                        console.log("winning: ", state);
                 }).saveB64Blob(b64Blob);
            };

        });

服务器代码

function saveB64Blob(b64Blob) {
    var success = { success: false, url: null};
    Logger.log("Got blob: %s", b64Blob);
    try {

        Logger.log("GBlob: %s", blob);
        var file = DriveApp.createFile(blob);
        file.setSharing(DriveApp.Access.ANYONE_WITH_LINK, DriveApp.Permission.COMMENT);
        success = { success: true, url: file.getUrl() };
    } catch (error) {
        Logger.log("Error: %s", error);
    }
    return success;
}

function dataURItoBlob(dataURI) {
    // convert base64/URLEncoded data component to raw binary data held in a string
    var byteString;
    if (dataURI.split(',')[0].indexOf('base64') >= 0)
        byteString = Utilities.base64Decode(dataURI.split(',')[1]);
    else
        byteString = decodeURI(dataURI.split(',')[1]);

    // separate out the mime component
    var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];

    return Utilities.newBlob(byteString, mimeString, "video.webm");
}
