我有一段与Keycloak和JS相关的代码。这段代码工作得非常好,除了当令牌过期时需要外部调用刷新令牌方法。如何在令牌过期时自动刷新令牌。
var keycloak = Keycloak('keycloak.json');
keycloak.init({ onLoad: 'login-required' })
.success(reloadData)
.error(function(errorData) {
document.getElementById('customers').innerHTML = '<b>Failed to load data. Error: ' + JSON.stringify(errorData) + '</b>';
});
var loadData = function () {
document.getElementById('subject').innerHTML = keycloak.subject;
if (keycloak.idToken) {
document.getElementById('profileType').innerHTML = 'IDToken';
document.getElementById('username').innerHTML = keycloak.idTokenParsed.preferred_username;
document.getElementById('email').innerHTML = keycloak.idTokenParsed.email;
document.getElementById('name').innerHTML = keycloak.idTokenParsed.name;
document.getElementById('givenName').innerHTML = keycloak.idTokenParsed.given_name;
document.getElementById('familyName').innerHTML = keycloak.idTokenParsed.family_name;
} else {
keycloak.loadUserProfile(function() {
document.getElementById('profileType').innerHTML = 'Account Service';
document.getElementById('username').innerHTML = keycloak.profile.username;
document.getElementById('email').innerHTML = keycloak.profile.email;
document.getElementById('name').innerHTML = keycloak.profile.firstName + ' ' + keycloak.profile.lastName;
document.getElementById('givenName').innerHTML = keycloak.profile.firstName;
document.getElementById('familyName').innerHTML = keycloak.profile.lastName;
}, function() {
document.getElementById('profileType').innerHTML = 'Failed to retrieve user details. Please enable claims or account role';
});
}
var url = '/database/customers';
var req = new XMLHttpRequest();
req.open('GET', url, true);
req.setRequestHeader('Accept', 'application/json');
req.setRequestHeader('Authorization', 'Bearer ' + keycloak.token);
req.onreadystatechange = function () {
if (req.readyState == 4) {
if (req.status == 200) {
var users = JSON.parse(req.responseText);
var html = '';
for (var i = 0; i < users.length; i++) {
html += '<p>' + users[i] + '</p>';
}
document.getElementById('customers').innerHTML = html;
console.log('finished loading data');
}
}
}
req.send();
};
var loadFailure = function () {
document.getElementById('customers').innerHTML = '<b>Failed to load data. Check console log</b>';
};
var reloadData = function () {
keycloak.updateToken(10)
.success(loadData)
.error(function() {
document.getElementById('customers').innerHTML = '<b>Failed to load data. User is logged out.</b>';
});
}
