我正嘗試使用Google Classroom API和服務帳戶創建Google課堂課程。我目前正在嘗試使用JavaScript，並且已經設置好了一切，並努力獲得課程列表。我建立了一個JWT並請求我收到的身份驗證令牌。Google Classroom API 401錯誤
{"access_token":"----ACCESS TOKEN HERE----------","token_type":"Bearer","expires_in":3600}
當我使用它來檢索用戶的課程列表（通過GET）沒有問題。我收到一份適當的答覆，並列出一系列課程，然後我將其列入表格。
當我嘗試使用相同的過程中要儘量創造一個療程（通過POST），我得到一個401錯誤：
{
"error": {
"code": 401,
"message": "The request does not have valid authentication credentials.",
"status": "UNAUTHENTICATED"
}
}
這是我用它來驗證碼：
function authenticate(callback) {
function b64EncodeUnicode(str) {
str = JSON.stringify(str);
return btoa(encodeURIComponent(str).replace(/%([0-9A-F]{2})/g, function(match, p1) {
return String.fromCharCode('0x' + p1);
}));
}
// constuct the JWT
var jwtHeader = {
"alg":"RS256",
"typ":"JWT"
}
jwtHeader = JSON.stringify(jwtHeader);
//construct the Claim
var jwtClaim = {
"iss":"[email protected]serviceaccount.com",
"scope":"https://www.googleapis.com/auth/classroom.courses https://www.googleapis.com/auth/classroom.rosters",
"sub":"[email protected]", //this is an admin account I shouldn't really need this but tried with and without it
"aud":"https://www.googleapis.com/oauth2/v4/token",
"exp":(Math.round(new Date().getTime()/1000) + 60 * 10),
"iat":Math.round(new Date().getTime()/1000)
}
jwtClaim = JSON.stringify(jwtClaim);
//construct the signature
var key="-----BEGIN PRIVATE KEY-----Removed-----END PRIVATE KEY-----\n";
var jwtSign = b64EncodeUnicode(jwtSign);
var sJWT = KJUR.jws.JWS.sign("RS256", jwtHeader, jwtClaim, key);
var jwt = jwtHeader + "." + jwtClaim + "." + sJWT;
//request Token
var grantType = "urn:ietf:params:oauth:grant-type:jwt-bearer";
var tokenRequest = "grant_type=" + grantType + "&assertion=" + sJWT;
var postURL = "https://www.googleapis.com/oauth2/v4/token"
request = $j.ajax({
url: postURL,
type: "post",
data: tokenRequest,
success: callback
});
}
這是我用來獲取課程列表的代碼。 （這工作）
$j("#getClasses").click(function(event){
function getClasses(callback){
authenticate(function(data){
console.log(JSON.stringify(data));
var access_token = data["access_token"];
var apiUrl = 'https://classroom.googleapis.com/v1/courses'
var myData = 'teacherId=~(teacheremail)&access_token='+access_token;
var files = $j.ajax({
url: apiUrl,
type: "get",
data: myData,
success: function (data) {
var retreivedClasses = JSON.stringify(data);
for(var i = 0; i < data['courses'].length; i++){
nextObject = data['courses'];
$j('#classListTable').append('<tr><td>' + nextObject[i]['name'] + '</td><td>' + nextObject[i]['courseState'] + '</td><td>' + nextObject[i]['enrollmentCode'] + '</td></tr>');
}
//$j('#classList').text(retreivedClasses);
}
});
});
}
getClasses();
});
這是我用來通過POST創建課程的代碼。我硬編碼了一些變量進行測試，但仍然給出了401錯誤。
$j("#createClass").click(function(event){
function createClass(callback){
authenticate(function(data){
console.log(JSON.stringify(data));
var access_token = data["access_token"];
var tokenInfo = $j.ajax({
url: 'https://www.googleapis.com/oauth2/v3/tokeninfo',
type: 'get',
data: "access_token="+access_token
});
var apiUrl = 'https://classroom.googleapis.com/v1/courses'
var myData = 'access_token='+access_token + '&[email protected]&name=myClass'
console.log(myData);
var newGoogleClassroom = $j.ajax({
url: apiUrl,
type: "post",
data: myData,
success: function (data) {
var apiResponse = JSON.stringify(data);
$j('#classCreated').text(apiResponse);
}
});
});
};
createClass();
});
最後，這是我得到令牌信息時得到的結果。這看起來好像沒什麼問題，即適當的範圍：（但我新的這個）
{
"azp": "removed",
"aud": "removed",
"scope": "https://www.googleapis.com/auth/classroom.courses https://www.googleapis.com/auth/classroom
.rosters",
"exp": "1474512198",
"expires_in": "3600",
"access_type": "offline"
}
我很感謝任何幫助。 Doug
P.S.我得到這段代碼的安全含義。它只在一個安全的環境中進行實驗。它不會看到白天的光芒。
