尝试将文件上传到 google drive api 时收到 404，怀疑是数据格式问题

问题描述

我正在尝试使用 JS 将一些动态生成的数据 (json) 保存到我的谷歌驱动器上的(新)文件中，但我在 POST 中不断收到这些无用的错误.

Im trying to save some dynamically generated data (json) to a (new) file on my google drive using JS but i keep getting these unhelpful errors on my POST.

起初我以为我发布到错误的地址，但在更改数据内容后，错误从 404 更改为 400，所以现在我怀疑错误与格式有关(因为我不太了解这些多部分内容).

At first I thought I was POSTing to the wrong address, but after changing the data content the error changed from 404 to 400 so now i suspect that the error is formatting related (since i dont understand this multipart stuff so well).

代码如下:

function gDriveSaveProject(data, gDriveFolderID, currentProj, callback )
    {
    const boundary = '-------314159265358979323846';
    const delimiter = "
--" + boundary + "
";
    const close_delim = "
--" + boundary + "--";

    var metadata = {
    'title': currentProj + ".lo",
    'mimeType': 'application/json',
    'parents' : [{'id' : gDriveFolderID}]
        };

    var multipartRequestBody =
        delimiter +
        'Content-Type: application/json

' +
        JSON.stringify(metadata) +
        delimiter +
        'Content-Type: application/json
' +
        'Content-Transfer-Encoding: base64
' +
        '
' +
        btoa(JSON.stringify(data)) +
        close_delim;

    var request = gapi.client.request({
        'path': '/upload/drive/v2/files',
        'method': 'POST',
        'params': {'uploadType': 'multipart'},
        'headers': {
            'Content-Type': 'multipart/mixed; boundary="' + boundary + '"'
            },
        //'body': ""   // using this gives me 400 instead of 404
        'body': multipartRequestBody
        });

    request.execute(callback);
    }

代码基于 google drive sdk 示例，但使用动态创建的数据而不是上传的文件和目标目录而不是根目录.

the code is based on the google drive sdk example, but using dynamically created data instead of a uploaded file and a target directory instead of the root.

谢谢

推荐答案

想通了！

结果是我为父文件夹提供了错误的 ID，这就是为什么我得到 404，但由于它没有作为正确的错误对象返回，我认为 404 是因为/upload/v2/drive/files 未找到.

Turned out that I was supplying a faulty ID for the parent folder, and that is why i got the 404, but since it wasnt returned as a proper error object, I assumed the 404 was because the /upload/v2/drive/files wasnt found.

也许谷歌可以让像我这样的白痴更清楚;)

Maybe google could make it a bit clearer for idiots like me ;)
