尝试将文件上传到Google Drive api时遇到404，并怀疑数据格式问题 [英] getting a 404 when trying to upload a file to the google drive api, suspecting a data formatting issue

问题描述

我试图用JS保存一些动态生成的数据（json）到我的谷歌驱动器上的（新）起初我以为我是POST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是格式相关的（因为我不太了解这个多部分的东西）。

代码如下所示：

pre $ function $ gDriveSaveProject（data，gDriveFolderID，currentProj ，回调）
{
const boundary ='------- 314159265358979323846';
const delimiter =\r\\\
--+ boundary +\r\\\
;
const close_delim =\r\\\
--+ boundary + - ;
$ b var metadata = {
'title'：currentProj +.lo，
'mimeType'：'application / json'，
'parents'：[ {'id'：gDriveFolderID}]
};

var multipartRequestBody =
分隔符+
'Content-Type：application / json\r\\\
\r\''+
JSON.stringify （元数据）+
分隔符+
'Content-Type：application / json\r\''+
'Content-Transfer-Encoding：base64 \r\\\
'+
'\r\\\
'+
btoa（JSON.stringify（data））+
close_delim;

var request = gapi.client.request（{$ b $'path'：'/ upload / drive / v2 / files'，
'method'：'POST'，
'params'：{'uploadType'：'multipart'}，
'headers'：{
'Content-Type'：'multipart / mixed; boundary =''+ boundary +' '
}，
//'body'：//使用这个函数给我400而不是404
'body'：multipartRequestBody
}）;

request.execute（callback）;
}

该代码基于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。

感谢

解决方案

我发现我为父文件夹提供了一个错误的ID，这就是为什么我得到了404，但是因为它没有返回作为一个适当的错误对象，我认为404是因为/上传/ V2 /驱动器/文件wasnt找不到。

也许谷歌可以使它更清晰一点像我这样的傻瓜;）

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.

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).

code is like:

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

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

    var multipartRequestBody =
        delimiter +
        'Content-Type: application/json\r\n\r\n' +
        JSON.stringify(metadata) +
        delimiter +
        'Content-Type: application/json\r\n' +
        'Content-Transfer-Encoding: base64\r\n' +
        '\r\n' +
        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);
    }

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.

thanks

Figured it out!

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.

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