[英]Ember Simple Auth on Firefox: authentication throws Error
我正在扩展Ember Simple Auth的基本身份验证类,以允许通过Google进行身份验证。 到目前为止,它可以在Safari 8和Chrome 41(均在优胜美地上使用)上正常运行,没有错误。 但是,在Firefox 35上,它将引发在其他浏览器上不会发生的错误。 这是我的Google身份验证器类:
App.GoogleAuthenticator = SimpleAuth.Authenticators.Base.extend({
// constants for Google API
GAPI_CLIENT_ID: 'the client id',
GAPI_SCOPE: ['email'],
GAPI_TOKEN_VERIFICATION_ENDPOINT: 'https://www.googleapis.com/oauth2/v2/tokeninfo',
// method for scheduleing a single token refresh
// time in milliseconds
scheduleSingleTokenRefresh: function(time) {
var self = this;
return new Ember.RSVP.Promise(function(resolve, reject) {
Ember.run.later(self, function() {
gapi.auth.authorize({
client_id: self.GAPI_CLIENT_ID,
scope: self.GAPI_SCOPE,
immediate: true
}, function(data) {
if (data && !data.error) {
resolve(data);
} else {
reject((data || {}).error);
}
});
}, time);
});
},
// WIP: recursive method that reschedules another token refresh after the previous scheduled one was fulfilled
// usage: scheduleTokenRefreshes(time until token should refresh for the first time, time between subsequent refreshes)
// usage: scheduleTokenRefreshes(time between refreshes)
scheduleTokenRefreshes: function(time1, time2) {
var self = this;
// if there is a time2, schedule a single refresh, wait for it to be fulfilled, then call myself to schedule again
if (!Ember.isEmpty(time2)) {
self.scheduleSingleTokenRefresh(time1)
.then(function() {
self.scheduleTokenRefreshes(time2);
});
// if there isn't a time2, simply schedule a single refresh, then call myself to schedule again
} else {
self.scheduleSingleTokenRefresh(time1)
.then(function() {
self.scheduleTokenRefreshes(time1);
});
}
},
// method that restores the session on reload
restore: function(data) {
var self = this;
return new Ember.RSVP.Promise(function(resolve, reject) {
console.log(data);
if (Ember.isEmpty(data.access_token)) {
reject();
return;
}
// schedule a refresh 15 minutes before it expires or immediately if it expires in < 15
var timeNow = Math.floor(Date.now() / 1000);
var expiresAt = +data.expires_at;
var timeDifference = expiresAt - timeNow;
var schedulingDelay = Math.floor(timeDifference - 15 * 60);
schedulingDelay = schedulingDelay < 0 ? 0 : schedulingDelay;
self.scheduleTokenRefreshes(schedulingDelay * 1000, 45 * 60);
resolve(data);
});
},
// method that authenticates
authenticate: function() {
var self = this;
return new Ember.RSVP.Promise(function(resolve, reject) {
gapi.auth.authorize({
client_id: self.GAPI_CLIENT_ID,
scope: self.GAPI_SCOPE
}, function(data) {
if (data && !data.error) {
// schedule a refresh in 45 minutes
var schedulingDelay = 45 * 60;
self.scheduleTokenRefreshes(schedulingDelay * 1000);
resolve(data);
} else {
reject((data || {}).error);
}
});
});
},
// method that logs the user out and revokes the token
invalidate: function(data) {
var self = this;
return new Ember.RSVP.Promise(function(resolve, reject) {
// send a GET request to revoke the token
Ember.$.ajax({
type: 'GET',
url: 'https://accounts.google.com/o/oauth2/revoke?token=' + self.get('session.access_token'),
contentType: 'application/json',
dataType: 'jsonp'
})
.done(function(successData) {
resolve(successData);
})
.fail(function(error) {
reject(error);
});
});
}
});
在Google端成功登录后,当弹出窗口关闭时,此错误将显示在Firefox的控制台上:

这是版本信息:

DEBUG: jQuery : 2.1.3
DEBUG: Ember Simple Auth : 0.7.2
最令人困惑的是,它仅出现在Firefox上。 它是Ember Simple Auth还是Ember中的错误? 我如何解决它?
我不只知道Firefox会引发错误(我在Chrome 40中也遇到过类似的错误),但是使用Ember 1.9的ember-simple-auth 0.7.2中存在一个错误,该错误禁止在authenticate
发送实际的错误响应身份验证器中的方法。
如果您在authenticate
的拒绝函数中返回reject()
,则不会引发其他错误。 但是,这不会传播错误状态或消息,因此我认为这是一个错误。
在github上针对此问题提出了一种解决方法,方法是暂时设置Ember.onerror=Ember.K
以便不会传播其他错误,尽管它将传播带有错误状态的原始authenticate
拒绝。
github存储库中的问题仅提到测试此问题,但是我在普通代码中遇到了此问题。
参见: https : //github.com/simplabs/ember-simple-auth/issues/407
原来错误是在authenticate
方法的resolve
部分上。 这是解决问题的方法:
App.GoogleAuthenticator = SimpleAuth.Authenticators.Base.extend({
authenticate: function() {
return new Ember.RSVP.Promise(function(resolve, reject) {
gapi.auth.authorize({
client_id: 'the client id',
scope: ['the scopes'],
}, function(data) {
if (data && !data.error) {
resolve({
access_token: data.access_token // !! passing the entire 'data' object caused the error somehow
});
} else {
reject((data || {}).error);
}
});
});
},
// ...
});
我仍然不太确定为什么这会导致错误。 也许Google API的响应(整体上)与Ember Simple Auth不兼容。
