我的客户端在Google云运行上运行了GraphQL API。
我已经收到一个用于身份验证以及访问gcloud命令行工具的服务帐户。
像这样使用gcloud命令行时：
gcloud auth print-identity-token
我可以生成一个令牌，该令牌可用于向api发出发布请求。这样可以正常工作，我可以成功地从邮递员，失眠症和我的nodejs应用程序向api发出成功的发布请求。
但是，当我将JWT身份验证与“ googleapis”或“ google-auth” npm库一起使用时，如下所示：
var { google } = require('googleapis')
let privatekey = require('./auth/google/service-account.json')
let jwtClient = new google.auth.JWT(
privatekey.client_email,
null,
privatekey.private_key,
['https://www.googleapis.com/auth/cloud-platform']
)
jwtClient.authorize(function(err, _token) {
if (err) {
console.log(err)
return err
} else {
console.log('token obj:', _token)
}
})
这将输出一个“ bearer”令牌：
token obj: {
access_token: 'ya29.c.Ko8BvQcMD5zU-0raojM_u2FZooWMyhB9Ni0Yv2_dsGdjuIDeL1tftPg0O17uFrdtkCuJrupBBBK2IGfUW0HGtgkYk-DZiS1aKyeY9wpXTwvbinGe9sud0k1POA2vEKiGONRqFBSh9-xms3JhZVdCmpBi5EO5aGjkkJeFI_EBry0E12m2DTm0T_7izJTuGQ9hmyw',
token_type: 'Bearer',
expiry_date: 1581954138000,
id_token: undefined,
refresh_token: 'jwt-placeholder'
}
但是，该承载令牌无法像上面的令牌那样工作，并且在发出与gcloud命令“ gcloud auth print-identity-token”相同的请求时，始终会给出“未经授权的错误401”。
请帮助，我不确定为什么第一个承载令牌有效，但JWT生成的令牌无效。
我还尝试过获取身份令牌，而不是像这样的访问令牌：
let privatekey = require('./auth/google/service-account.json')
let jwtClient = new google.auth.JWT(
privatekey.client_email,
null,
privatekey.private_key,
[]
)
jwtClient
.fetchIdToken('https://my.audience.url')
.then((res) => console.log('res:', res))
.catch((err) => console.log('err', err))
这会打印一个身份令牌，但是，使用它还会给出“ 401未经授权”的消息。
请注意，以下任何这些方法都可与命令行标识令牌一起使用，但是当通过JWT生成时，它将返回401
方法1：
const client = new GraphQLClient(baseUrl, {
headers: {
Authorization: 'Bearer ' + _token.id_token
}
})
const query = `{
... my graphql query goes here ...
}`
client
.request(query)
.then((data) => {
console.log('result from query:', data)
res.send({ data })
return 0
})
.catch((err) => {
res.send({ message: 'error ' + err })
return 0
})
}
方法2（使用我通过google-auth创建的“授权”客户端）：
const res = await client.request({
url: url,
method: 'post',
data: `{
My graphQL query goes here ...
}`
})
console.log(res.data)
}

这是node.js中的一个示例，该示例正确创建了具有正确受众群体的身份令牌，以调用Cloud Run或Cloud Functions服务。
修改此示例以适合GraphQLClient。不要忘记在每个调用中都包含Authorization标头。
// This program creates an OIDC Identity Token from a service account
// and calls an HTTP endpoint with the Identity Token as the authorization
var { google } = require('googleapis')
const request = require('request')
// The service account JSON key file to use to create the Identity Token
let privatekey = require('/config/service-account.json')
// The HTTP endpoint to call with an Identity Token for authorization
// Note: This url is using a custom domain. Do not use the same domain for the audience
let url = 'https://example.jhanley.dev'
// The audience that this ID token is intended for (example Google Cloud Run service URL)
// Do not use a custom domain name, use the Assigned by Cloud Run url
let audience = 'https://example-ylabperdfq-uc.a.run.app'
let jwtClient = new google.auth.JWT(
privatekey.client_email,
null,
privatekey.private_key,
audience
)
jwtClient.authorize(function(err, _token) {
if (err) {
console.log(err)
return err
} else {
// console.log('token obj:', _token)
request(
{
url: url,
headers: {
"Authorization": "Bearer " + _token.id_token
}
},
function(err, response, body) {
if (err) {
console.log(err)
return err
} else {
// console.log('Response:', response)
console.log(body)
}
}
);
}
})

您可以找到节点OAuth2的官方文档
A complete OAuth2 example:
const {OAuth2Client} = require('google-auth-library');
const http = require('http');
const url = require('url');
const open = require('open');
const destroyer = require('server-destroy');
// Download your OAuth2 configuration from the Google
const keys = require('./oauth2.keys.json');
/**
* Start by acquiring a pre-authenticated oAuth2 client.
*/
async function main() {
const oAuth2Client = await getAuthenticatedClient();
// Make a simple request to the People API using our pre-authenticated client. The `request()` method
// takes an GaxiosOptions object. Visit https://github.com/JustinBeckwith/gaxios.
const url = 'https://people.googleapis.com/v1/people/me?personFields=names';
const res = await oAuth2Client.request({url});
console.log(res.data);
// After acquiring an access_token, you may want to check on the audience, expiration,
// or original scopes requested. You can do that with the `getTokenInfo` method.
const tokenInfo = await oAuth2Client.getTokenInfo(
oAuth2Client.credentials.access_token
);
console.log(tokenInfo);
}
/**
* Create a new OAuth2Client, and go through the OAuth2 content
* workflow. Return the full client to the callback.
*/
function getAuthenticatedClient() {
return new Promise((resolve, reject) => {
// create an oAuth client to authorize the API call. Secrets are kept in a `keys.json` file,
// which should be downloaded from the Google Developers Console.
const oAuth2Client = new OAuth2Client(
keys.web.client_id,
keys.web.client_secret,
keys.web.redirect_uris[0]
);
// Generate the url that will be used for the consent dialog.
const authorizeUrl = oAuth2Client.generateAuthUrl({
access_type: 'offline',
scope: 'https://www.googleapis.com/auth/userinfo.profile',
});
// Open an http server to accept the oauth callback. In this simple example, the
// only request to our webserver is to /oauth2callback?code=<code>
const server = http
.createServer(async (req, res) => {
try {
if (req.url.indexOf('/oauth2callback') > -1) {
// acquire the code from the querystring, and close the web server.
const qs = new url.URL(req.url, 'http://localhost:3000')
.searchParams;
const code = qs.get('code');
console.log(`Code is ${code}`);
res.end('Authentication successful! Please return to the console.');
server.destroy();
// Now that we have the code, use that to acquire tokens.
const r = await oAuth2Client.getToken(code);
// Make sure to set the credentials on the OAuth2 client.
oAuth2Client.setCredentials(r.tokens);
console.info('Tokens acquired.');
resolve(oAuth2Client);
}
} catch (e) {
reject(e);
}
})
.listen(3000, () => {
// open the browser to the authorize url to start the workflow
open(authorizeUrl, {wait: false}).then(cp => cp.unref());
});
destroyer(server);
});
}
main().catch(console.error);

*/
// const url = 'https://YOUR_CLOUD_RUN_URL.run.app';
const {GoogleAuth} = require('google-auth-library');
const auth = new GoogleAuth();
async function request() {
if (!targetAudience) {
// Use the request URL hostname as the target audience for Cloud Run requests
const {URL} = require('url');
targetAudience = new URL(url).origin;
}
console.info(
`request Cloud Run ${url} with target audience ${targetAudience}`
);
const client = await auth.getIdTokenClient(targetAudience);
const res = await client.request({url});
console.info(res.data);
}
request().catch(err => {
console.error(err.message);
process.exitCode = 1;
});
// [END google_auth_idtoken_cloudrun]

对于那些由于缺乏文档而不想浪费一整天工作的人。这是当今世界公认的答案，因为JWT类不再在构造函数中接受受众。
import { JWT } from "google-auth-library"
const client = new JWT({
forceRefreshOnFailure: true,
key: service_account.private_key,
email: service_account.client_email,
})
const token = await client.fetchIdToken("cloud run endpoint")
const { data } = await axios.post("cloud run endpoint"/path, payload, {
headers: {
Authorization: `Bearer ${token}`
}
})
return data
