How to send Outlook messages by javascript SDK? - microsoft-graph-api

Question

I searched for a long time but I did not find a relevant solution.
When I send mail via Microsoft Graph API to get 403, I do not know where the problem is
{
statusCode: 403,
code: "ErrorAccessDenied",
message: "Access is denied. Check credentials and try again."
}
Code:
makeSilentTokenRequest
//The static key authentication request
function makeSilentTokenRequest(callback) {
// Build up a hidden iframe
var iframe = $('<iframe/>');
iframe.attr('id', 'auth-iframe');
iframe.attr('name', 'auth-iframe');
iframe.appendTo('body');
iframe.hide();
iframe.load(function () {
callback(localStorage.accessToken);
});
iframe.attr('src', buildAuthUrl() + '&prompt=none&domain_hint=' +
localStorage.userDomainType + '&login_hint=' +
localStorage.userSigninName);
}
getAccessToken
//Verify refresh token function
function getAccessToken(callback) {
var now = new Date().getTime();
var isExpired = now > parseInt(localStorage.tokenExpires);
// Do we have a token already?
if (localStorage.accessToken && !isExpired) {
// Just return what we have
if (callback) {
callback(localStorage.accessToken);
}
} else {
// Attempt to do a hidden iframe request
makeSilentTokenRequest(callback);
}
}
getUserEmailAddress
function getUserEmailAddress(callback) {
//I saved it in localStorage
if (localStorage.userEmail) {
return localStorage.userEmail;
} else {
//getAccessToken
getAccessToken(function (accessToken) {
if (accessToken) {
// Create a Graph client
var client = MicrosoftGraph.Client.init({
authProvider: (done) => {
// Just return the token
done(null, accessToken);
}
});
// Get the Graph /Me endpoint to get user email address
client
.api('/me')
.get((err, res) => {
if (err) {
callback(null, err);
} else {
callback(res.mail);
}
});
} else {
var error = {
responseText: 'Could not retrieve access token'
};
callback(null, error);
}
});
}
}
sendMail
//sendMail
function sendMail(message) {
getUserEmailAddress(function (userEmail, error) {
if (error) {
renderError('getUserEmailAddress failed', error.responseText);
} else {
getAccessToken(function (accessToken) {
if (accessToken) {
// Create a Graph client
var client = MicrosoftGraph.Client.init({
authProvider: (done) => {
// Just return the token
done(null, accessToken);
}
});
client
.api('/me/sendMail')
.header('Authorization', 'Bearer ' + accessToken)
.header('Content-Type', "application/json")
.post(message, (err, res) => {
if (err) {
console.log(err);
//callback(null, err);
} else {
console.log(res);
//callback(res.value);
}
});
} else {
var error = {
responseText: 'Could not retrieve access token'
};
//callback(null, error);
}
});
}
})
}
createMail
function createMail(message,callback){
getUserEmailAddress(function(userEmail, error) {
if (error) {
renderError('getUserEmailAddress failed', error.responseText);
} else {
getAccessToken(function(accessToken) {
if (accessToken) {
// Create a Graph client
var client = MicrosoftGraph.Client.init({
authProvider: (done) => {
// Just return the token
done(null, accessToken);
}
});
client
.api('/me/messages')
.header('Authorization', 'Bearer ' +accessToken)
.header('Content-Type', "application/json")
.post(message,(err, res) => {
if (err) {
callback(res);
console.log("创建失败！");
} else {
callback(res);
console.log("创建成功！");
}
});
} else {
var error = { responseText: 'Could not retrieve access token' };
//callback(null, error);
}
});
}
})
}

There isn't enough to go on here but the error message is telling you that your accessToken isn't valid.
I can't see which scopes are you requesting or which authorization workflow you executing so I can't pinpoint precisely why it is invalid.
