Sharepoint list item using Api Rest - rest

Question

I need to get a list's items, so I created this function
export function retrieveSPItems(spToken, alias) {
var url = `{path_to_my_site}/_api/web/Lists/getByTitle('Briefs')/ItemCount`;
var myHeaders = new Headers({
Accept: "application/json;odata=nometadata",
Authorization: spToken,
});
return fetch(url, {
method: "get",
headers: myHeaders,
}).then((response) => response.json());
}
As a output I get 3000.
when I change the url to
var url = `{path_to_my_site}/_api/web/Lists/getByTitle('Briefs')/Items`;
I get an empty list!
PS :
It's work in Postman with no problem
The token is generated by adaljs :
Get Token
authContext.acquireToken(SP_BASE_URL, function (error, token){....})
Adal config
export const adalConfig = {
tenant: CURRENT_TENANT,
clientId: CURRENT_APP_ID,
endpoints: {
api: CURRENT_APP_ID,
graph: GRAPH_BASE_URL,
sharepoint: SP_BASE_URL,
},
cacheLocation: "localStorage",
validateAuthority: true,
};
So I need to know :
what the reason fot this issue?
How can I fix it?

It's too general information, you need debug and figure out the detailed error information.
My test demo:
<script type="text/javascript" src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="Scripts/adal.js"></script>
<script type="text/javascript">
var authContext = null;
var user = null;
(function () {
window.config = {
instance: 'https://login.microsoftonline.com/',
tenant: 'xxx.onmicrosoft.com',
clientId: '9afc37cb-x-x-x-xxx',
postLogoutRedirectUri: window.location.origin,
endpoints: {
graphApiUri: "https://graph.microsoft.com",
sharePointUri: "https://xxx.sharepoint.com/",
},
cacheLocation: 'localStorage' // enable this for IE, as sessionStorage does not work for localhost.
};
authContext = new AuthenticationContext(config);
var isCallback = authContext.isCallback(window.location.hash);
authContext.handleWindowCallback();
//$errorMessage.html(authContext.getLoginError());
if (isCallback && !authContext.getLoginError()) {
window.location = authContext._getItem(authContext.CONSTANTS.STORAGE.LOGIN_REQUEST);
}
user = authContext.getCachedUser();
if (!user) {
authContext.login();
}
//authContext.acquireToken(window.config.clientId, function (error, token) {
// console.log('---');
//})
authContext.acquireToken(window.config.endpoints.sharePointUri, function (error, token) {
alert(token);
if (error || !token) {
console.log("ADAL error occurred: " + error);
return;
}
else {
var listUri = window.config.endpoints.sharePointUri + "sites/lee/_api/web/lists/GetByTitle('mylist')/items?$select=Title";
$.ajax({
type: "GET",
url: listUri,
headers: {
"Authorization": "Bearer " + token,
"accept": "application/json;odata=verbose"
}
}).done(function (response) {
console.log("Successfully fetched list from SharePoint.");
var items = response.d.results;
for (var i = 0; i < items.length; i++) {
console.log(items[i].Title);
$("#SharePoint").append("<li>" + items[i].Title + "</li>");
}
}).fail(function () {
console.log("Fetching list from SharePoint failed.");
})
}
})
}());
</script>
