节点 js 与 gmail api,API 返回错误:错误:unauthorized_client
node js with gmail api, The API returned an error: Error: unauthorized_client
编辑:错误发生在这段代码上:
var gmail = google.gmail('v1');
gmail.users.labels.list({
auth: auth,
userId: 'me',
}, function(err, response) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
我正在使用带有Node js的gmail api。当我浏览他们的快速入门指南时,我不断收到此错误。
https://developers.google.com/gmail/api/quickstart/nodejs
The API returned an error: Error: unauthorized_client
请记住,我使用我的电子邮件地址完成了快速入门,一切都很好。完全没有错误。我决定创建一个虚拟电子邮件以进行测试。我所做的唯一更改是step 1-g
切换client_secret.json
文件以保存新的凭据和密钥。我尝试切换回旧文件,但错误仍然存在。
在页面底部提供的链接中,它指出。
Authorization information is stored on the file system, so subsequent executions will not prompt for authorization. Would I have to clear or refresh the information? If so how can I do this?
如果有帮助,我将重新发布快速入门.js文件中的所有代码。
var fs = require('fs');
var readline = require('readline');
var google = require('googleapis');
var googleAuth = require('google-auth-library');
var SCOPES = ['https://www.googleapis.com/auth/gmail.readonly'];
var TOKEN_DIR = (process.env.HOME || process.env.HOMEPATH ||
process.env.USERPROFILE) + '/.credentials/';
var TOKEN_PATH = TOKEN_DIR + 'gmail-nodejs-quickstart.json';
// Load client secrets from a local file.
fs.readFile('client_secret.json', function processClientSecrets(err, content) {
if (err) {
console.log('Error loading client secret file: ' + err);
return;

authorize(JSON.parse(content), listLabels);
});

function getNewToken(oauth2Client, callback) {

});
console.log('Authorize this app by visiting this url: ', authUrl);
var rl = readline.createInterface({

rl.question('Enter the code from that page here: ', function(code) {
rl.close();
oauth2Client.getToken(code, function(err, token) {

console.log('Error while trying to retrieve access token', err);
return;

oauth2Client.credentials = token;
storeToken(token);

function storeToken(token) {
try {
fs.mkdirSync(TOKEN_DIR);

if (err.code != 'EEXIST') {
throw err;

}
fs.writeFile(TOKEN_PATH, JSON.stringify(token));
console.log('Token stored to ' + TOKEN_PATH);
}
/**
* Lists the labels in the user's account.
*
* @param {google.auth.OAuth2} auth An authorized OAuth2 client.
*/
function listLabels(auth) {
var gmail = google.gmail('v1');
gmail.users.labels.list({
auth: auth,
userId: 'me',
}, function(err, response) {
if (err) {
console.log('The API returned an error: ' + err);
return;
}
var labels = response.labels;
if (labels.length == 0) {
console.log('No labels found.');
} else {
console.log('Labels:');
for (var i = 0; i < labels.length; i++) {
var label = labels[i];
console.log('- %s', label.name);
}
}
});
}
我做了一个控制台.log在TOKEN_PATH
上,它给了我文件所在位置的路径。
我不得不删除文件
/Users/user/.credentials/gmail-nodejs-quickstart.json
这是我在Mac上找不到的隐藏文件夹。
