Google 服务帐户委派 404 错误

Question

我正在尝试使用服务帐户进行身份验证，以代表域上的用户帐户工作。我已委派管理员访问权限并添加到 GSuite 控制台。我可以使用以下内容获取访问令牌，但是批量请求复制驱动器文件会返回"代码：404，消息："找不到文件："。下面的代码是在Google Apps Script中编写的。 我在创建和验证服务帐户的过程中是否缺少某些内容？

var CREDENTIALS = {
private_key: "-----BEGIN PRIVATE KEY----- XXXXXXX n-----END PRIVATE KEY-----n",
client_email: "[e-mail]",
client_id: "1XXXXXXXXXXXXXXXX",
user_email: "[e-mail]",
scopes: ["https://www.googleapis.com/auth/drive","https://www.googleapis.com/auth/spreadsheets","https://www.googleapis.com/auth/userinfo.email","https://www.googleapis.com/auth/script.external_request"]
};

function oAuthToken(){
var url = "https://www.googleapis.com/oauth2/v3/token";
var header = {
alg: "RS256",
typ: "JWT",
};
var now = Math.floor(Date.now() / 1000);
var claim = {
iss: CREDENTIALS.client_id,
sub: CREDENTIALS.user_email,
scope: CREDENTIALS.scopes.join(" "),
aud: url,
exp: (now + 3600).toString(),
iat: now.toString(),
};
var signature = Utilities.base64Encode(JSON.stringify(header)) + "." + Utilities.base64Encode(JSON.stringify(claim));
var jwt = signature + "." + Utilities.base64Encode(Utilities.computeRsaSha256Signature(signature, CREDENTIALS.private_key));
var params = {
method: "post",
payload: {
assertion: jwt,
grant_type: "urn:ietf:params:oauth:grant-type:jwt-bearer",
},
};
var res = UrlFetchApp.fetch(url, params).getContentText();
return JSON.parse(res)
}

批处理过程有点粗糙，但这就是它的要点。

var request={
batchPath:
requests:[]
}
var backoff =0
function batch(request) {
var oAuth=oAuthToken().access_token
var url ='https://www.googleapis.com/'+request.batchPath
var body =request.requests
if(body.length<1){
return []
}
var boundary = 'xxxxxxxxxx';
var contentId = 0;
var data = '--' + boundary + 'rn';
for (var i in body) {
if(typeof body[i]=='object'){
data += 'Content-Type: application/httprn';
data += 'Content-ID: ' + ++contentId + 'rnrn';
data += body[i].method + ' ' + body[i].endpoint + 'rn';
data += body[i].requestBody ? 'Content-Type: application/json; charset=utf-8rnrn' : 'rn';
data += body[i].requestBody ? JSON.stringify(body[i].requestBody) + 'rn' : '';
data += "--" + boundary + 'rn';
}
}
var parseBatchRes = function(res) {
var splittedRes = res.split('--batch');
return splittedRes.slice(1, splittedRes.length - 1).map(function(e) {
return {
contentId: Number(e.match(/Content-ID: response-(d+)/)[1]),
status: Number(e.match(/HTTP/d+.d+ (d+)/)[1]),
object: JSON.parse(e.match(/{[Ss]+}/)[0]),
};
});
};
var payload = Utilities.newBlob(data).getBytes();
var head = {Authorization: 'Bearer ' + oAuth}
var options = {
method: 'POST', 
contentType: 'multipart/mixed; boundary=' + boundary,
payload: payload,
headers: head,
muteHttpExceptions: false
};
var complete=false;
var finalResponse=[];
for (var n=0; n<=backoff; n++) {
if(complete){
break;
}
var complete = true
console.log('backoff',n);
var response =UrlFetchApp.fetch(url, options).getContentText();
for(var j=0;j<response.length;j++){
if(response[r].status!=200){
var complete = false
}
}
}
}

Answer 1

将supportsAllDrives = true查询参数添加到请求中。

这些参数指示请求应用程序是否同时支持"我的云端硬盘"和共享云端硬盘，默认值为false。
