英文:
trying to connect to gmail api using a service account on nodejs
问题
这是我第一次使用Gmail API。我试图通过服务账号使用Gmail API。我的程序目标是仅解析我的电子邮件并查找特定关键词，然后与本地数据库进行比较。然而，我无法连接到Gmail API。我已经完成了创建服务账号、下载服务账号密钥JSON文件以及授予服务账号域代理权限的步骤。我还已经给予了https://mail.google.com/的范围。我只是试图证明我可以连接并且身份验证通过，通过进行一个getprofile调用。
这段代码不起作用，因为我返回了一个前提条件检查失败的错误。
唯一的代码我得到了一个400的错误，错误消息是前提条件检查失败。
我希望能看到get profile Gmail API调用的输出。我已经阅读了一些资料，我唯一的猜测是我需要做一些关于JWT的事情，这让我感到困惑。JWT和您下载的服务账号JSON文件是相同的吗？我感激任何人能提供的见解，谢谢。
英文:
It is my first time using the gmail api. I am trying to use the gmail api via a service account. The goal of my program is to parse emails through my email only and to look for certain keywords and compare them to a local database. However I am unable to connect to the gmail api. I did do the steps of creating the service account, downloading the service account key json file and giving permission to domain wide delegation to the service account. I have also given the scope of https://mail.google.com/. I am simply trying to prove I can connect and the authentication works by doing a getprofile call.
const {google} = require('googleapis');
const auth = new google.auth.GoogleAuth({
keyFile: './serviceaccountkey.json',
scopes: ['https://mail.google.com/'],
subject: 'admin@example.org',
});
const gmail1 = google.gmail({version: 'v1', auth: auth});
async function temp1(){
var cont = gmail1.users.getProfile({userId: "me",})
return cont;
}
console.log(temp1());
This does not work as I return an error of precondition check failed.
throw new common_1.GaxiosError(`Request failed with status code ${translatedResponse.status}`, opts, translatedResponse);
^
GaxiosError: Precondition check failed.
at Gaxios._request (C:\Users\user\Documents\FunctionAzure\node_modules\gaxios\build\src\gaxios.js:130:23)
the only code I get is 400 with message of precondition check failed.
I was expecting to see output for the get profile gmail api call. I have done some reading and my only guess is I need to do something with JWTs which I am confused about. Are JWTs and service account json file you download the same thing? I appreciate any insight anyone can offer, thank you

根据您的身份验证方式，我认为您应该直接请求公开 'auth' 的 gmail 子模块，即您的代码应该如下所示：
// 请求公开 auth 的 gmail 模块
const gmail = require('@googleapis/gmail')
// 提供身份验证信息
const auth = new gmail.auth.GoogleAuth({
keyFile: './serviceaccountkey.json',
scopes: ['https://mail.google.com/'],
subject: 'admin@example.org',
});
// 创建身份验证客户端
const authClient = await auth.getClient();
// 对 Gmail 进行身份验证并创建 Gmail 客户端
const gmail1 = await gmail.gmail({
version: 'v1',
auth: authClient
});
查看其文档中的示例 此处（查找 - 或者，您可以通过安装子模块直接调用 API 部分）。
英文:
Based on how you're authenticating, I think you should directly request the gmail submodule which exposes 'auth' i.e. your code should be
// request the gmail module which exposes auth
const gmail = require('@googleapis/gmail')
// provide information for authenticating
const auth = new gmail.auth.GoogleAuth({
keyFile: './serviceaccountkey.json',
scopes: ['https://mail.google.com/'],
subject: 'admin@example.org',
});
// create an auth client
const authClient = await auth.getClient();
// authenticate to gmail and create a gmail client
const gmail1 = await gmail.gmail({
version: 'v1',
auth: authClient
});
See the example in their documentation here (look for the section - Alternatively, you can make calls directly to the APIs by installing a submodule)
