【中文标题】如何长时间访问(离线)Google API?【英文标题】:How to take long access (offline) to Google API? 【发布时间】:2020-07-01 01:03:03 【问题描述】:我需要解决的任务是通过 WebBrowser 中的 JS 获得对 Google Sheets 和 Google Drive 的“gapi.auth2”访问权限,而不是长时间直接使用用户授予的权限(直到用户取回此权限)权限)。
我需要有可能更改(添加一些信息)到用户的 Google 表格。用户必须配置将添加哪些信息。这就是为什么我需要离线保存和使用访问信息(访问和刷新令牌)。
我试过的代码:
<div>
<p>Google Sheets API Quickstart</p>
<!--Add buttons to initiate auth sequence and sign out-->
<button id="authorize_button" style="display: none;">Authorize</button>
<button id="signout_button" style="display: none;">Sign Out</button>
<pre id="content" style="white-space: pre-wrap;"></pre>
<script type="text/javascript">
// Client ID and API key from the Developer Console
var CLIENT_ID = 'MyID.apps.googleusercontent.com';
var API_KEY = 'MyKey';
// Array of API discovery doc URLs for APIs used by the quickstart
var DISCOVERY_DOCS = ["https://sheets.googleapis.com/$discovery/rest?version=v4"];
// Authorization scopes required by the API; multiple scopes can be
// included, separated by spaces.
var SCOPES = "https://www.googleapis.com/auth/spreadsheets https://www.googleapis.com/auth/drive";
var authorizeButton = document.getElementById('authorize_button');
var signoutButton = document.getElementById('signout_button');
/**
* On load, called to load the auth2 library and API client library.
*/
function handleClientLoad()
gapi.load('client:auth2', initClient);
/**
* Initializes the API client library and sets up sign-in state
* listeners.
*/
function initClient()
gapi.client.init(
apiKey: API_KEY,
clientId: CLIENT_ID,
discoveryDocs: DISCOVERY_DOCS,
scope: SCOPES
).then(function ()
// Listen for sign-in state changes.
gapi.auth2.getAuthInstance().isSignedIn.listen(updateSigninStatus);
// Handle the initial sign-in state.
updateSigninStatus(gapi.auth2.getAuthInstance().isSignedIn.get());
authorizeButton.onclick = handleAuthClick;
signoutButton.onclick = handleSignoutClick;
, function(error)
appendPre(JSON.stringify(error, null, 2));
);
/**
* Called when the signed in status changes, to update the UI
* appropriately. After a sign-in, the API is called.
*/
function updateSigninStatus(isSignedIn)
if (isSignedIn)
authorizeButton.style.display = 'none';
signoutButton.style.display = 'block';
listMajors();
else
authorizeButton.style.display = 'block';
signoutButton.style.display = 'none';
/**
* Sign in the user upon button click.
*/
function handleAuthClick(event)
let instance = gapi.auth2.getAuthInstance();
console.log(instance);
let promise = instance.signIn();
console.log(gapi.auth2.getAuthInstance());
console.log(promise);
console.log(gapi.client);
console.log(gapi.client.getToken());
console.log(gapi.auth2);
console.log(gapi.auth2.getAuthInstance().currentUser.get().getAuthResponse());
console.log(gapi.auth2.getAuthInstance().currentUser.get());
console.log(gapi.auth2.getAuthInstance().currentUser);
console.log(instance.currentUser);
console.log(instance.currentUser.ie);
console.log(instance.currentUser.ie.uc);
console.log(instance.currentUser.ie.uc.access_token);
console.log(auth);
let auth = instance.currentUser.ie.uc.access_token;
let a = document.getElementById('my');
a.href += auth;
let xhr = new XMLHttpRequest();
xhr.setRequestHeader('Authorization', 'Bearer ' + "ya29.a0Adw1xeXfLePcaSdeluMmvtDrnrgbDibLToC22Vw5yOfIhOpQ1TqxFlROBozsBPbXL1GRYHumMltcLuJWNygtZ1m8IRpfx9n7I-oLQi4BpgaU98nx7InjquPqJ8Yc2aGvN9ac6HI9rqlDPJFTbhxKP37SzG_31x_u6vs");
xhr.
xhr.send();
/**
* Sign out the user upon button click.
*/
function handleSignoutClick(event)
gapi.auth2.getAuthInstance().signOut();
/**
* Append a pre element to the body containing the given message
* as its text node. Used to display the results of the API call.
*
* param string message Text to be placed in pre element.
*/
function appendPre(message)
var pre = document.getElementById('content');
var textContent = document.createTextNode(message + '\n');
pre.appendChild(textContent);
/**
* Print the names and majors of students in a sample spreadsheet:
* https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
*/
function listMajors()
gapi.client.sheets.spreadsheets.values.get(
spreadsheetId: '1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms',
range: 'Class Data!A2:E',
).then(function(response)
var range = response.result;
if (range.values.length > 0)
appendPre('Name, Major:');
for (i = 0; i < range.values.length; i++)
var row = range.values[i];
// Print columns A and E, which correspond to indices 0 and 4.
appendPre(row[0] + ', ' + row[4]);
else
appendPre('No data found.');
, function(response)
appendPre('Error: ' + response.result.error.message);
);
</script>
</div>
<script async defer src="https://apis.google.com/js/api.js"
onload="this.onload=function();handleClientLoad()"
onreadystatechange="if (this.readyState === 'complete') this.onload()">
</script>
我也尝试在浏览器中输入:“https://accounts.google.com/o/oauth2/auth?access_type=offline&prompt=consent&redirect_uri=https://localhost:44325/&client_id=MyID.apps.googleusercontent.com&scope=https://www.googleapis.com/auth/spreadsheets+https://www.googleapis.com/auth/drive&response_type=code&state=/profile”
redirect_uri 错误,在控制台中添加它没有帮助。
当我尝试使用 Quichstart .NET 应用程序时,它运行良好,但我只得到我的令牌,而不是我的客户。
如何使用 JS 离线访问我的客户 Google 数据?如果我的客户端允许我通过 WebBrowser 中的 JS 访问,我在哪里可以获得刷新令牌?
【问题讨论】:
【参考方案1】:正确的链接是 - https://accounts.google.com/o/oauth2/auth?access_type=offline&prompt=consent&redirect_uri=https://localhost:44325&client_id=MyID.apps.googleusercontent.com&scope=https://www.googleapis.com/auth/spreadsheets+https://www.googleapis.com/auth/drive&response_type=code&state=/profile
“redirect_uri=https://localhost:44325”不是“redirect_uri=https://localhost:44325/”
然后当我被重定向到“https://localhost:44325/”时,链接是下一个“https://localhost:44325/?state=/profile&code=4/xwFM---SOME SYMBOLS---&scope=https://www.googleapis.com/auth/drive%20https://www.googleapis.com/auth/spreadsheets”
我猜“4/xwFM---SOME SYMBOLS---”是我的刷新令牌。我明天去看看。
UPD。然后我在 POST 请求中使用此代码“https://accounts.google.com/o/oauth2/token”,并设置以下字段:
grant_type=authorization_code
code='the code from the previous step'
client_id='the client ID token created in the APIs Console'
client_secret='the client secret corresponding to the client ID'
redirect_uri='the URI registered with the client ID'
