Dealing with expired access tokens in OAuth2 implicit grant

阅读更多关于 Dealing with expired access tokens in OAuth2 implicit grant

问题 The specification of OAuth2 states that an authorization server must not issue a refresh token when using implicit grant. In our use case we protect a RESTful API with OAuth2 and use a Single Page Javascript application as a client for this API. As it would be very difficult to redirect to the authorization server after an access token has expired, we are searching for a better way to get a new valid token. I could think about two different approaches and wonder which one could be better: Use

阅读更多关于 Refactoring and removing unused CSS from SASS/LESS files

I am working on a big single page application [backbonejs and rails] which has LESS as the CSS preprocessor and the generated .css files has grown to such an extent that for IE we have to split it into 3 files with http://blesscss.com/ Though there are tools to detect unused css and linting css, I am unable to find a proper solution for refactoring LESS/SASS files directly from uncompiled files instead of a single large generated .css file. Would like to know what is the best approach doing these tasks? Thanks in advance ! For finding and remove unused CSS use Uncss which has implementation as

In a single-page app, what is the right way to deal with wrong URLs (404 errors)?

阅读更多关于 In a single-page app, what is the right way to deal with wrong URLs (404 errors)?

I am currently writing a web application using angularjs, but I think this question applies to any client-side javascript framework that does routing on the client side ( as angular does ). In a single-page app, what is the right way to deal with wrong URLs? Looking at a few major sites, I see that gmail will redirect to the inbox if you type any random URL below https://mail.google.com/mail/ . This happens server-side (with an http 300 code) or client-side, depending on whether the wrong path is before or after the # character. On the other hand, twitter shows a real HTTP 404 for any invalid

How to handle / ignore a bad route with durandal?

阅读更多关于 How to handle / ignore a bad route with durandal?

问题 I'm trying to conditionally block a route from being accessed. I think this can be done with guardRoute: http://durandaljs.com/documentation/Router/ function guardRoute(routeInfo, params, instance) : object - Before any route is activated, the guardRoute function is called. You can plug into this function to add custom logic to allow, deny or redirect based on the requested route. To allow, return true. To deny, return false. To redirect, return a string with the hash or url. You may also
