OAuth2 - Status 401 on OPTIONS request while retrieving TOKEN

阅读更多关于 OAuth2 - Status 401 on OPTIONS request while retrieving TOKEN

Our stack uses Backbone as our client-side app and Spring Boot as a RESTful API. We're trying to make basic authentication using OAuth2 with user providing username and password. We use Spring Security for authentication and jQuery $.ajax method for making requests. However the response we get is 401(unauthorized) status on preflight OPTIONS request before we can even POST header with our secret to authorize. However we can POST or GET any other resource without any problems. Server response for OPTIONS request is 200(ok) and then it follows up with POST request. So why is that an OPTIONS

Single Page Application and RESTful API

阅读更多关于 Single Page Application and RESTful API

A real RESTful API leverages hypermedia so that clients rely only on dynamic hypermedia provided by server to navigate through the application (the concept known as HATEOAS ) This concept is easily applicable to web applications but how do you apply it to Single Page Application as SPAs normally manage their state internally (without relying on the server as far as navigation is concerned) ? My feeling is that SPAs cannot fully leverage RESTful APIs or did I miss something ? Thanks Riana A SPA's particularity is it provides a more fluid user experience with the UI constructed on the client

Change detection API Underlying architecture in Angular

阅读更多关于 Change detection API Underlying architecture in Angular

问题 I was going through this article and was confused about how the change detection action works. https://vsavkin.com/change-detection-in-angular-2-4f216b855d4c The concept: Angular says it does not do dirty checking and there is no two binding as well as watching like in AngularJS 1.X. However, what I understand from Docs and few blogs + stacks is that there is a change detector attached to every component. However, from this stack overflow with @Gunter's response here: Understanding change

Getting Angular to work with a Moodle webservice

问题 I am building an application to get Json data from a Moodle web service, and using AngularJs to display the data in the app. There are multiple functions on the Moodle webservice, so I need multiple controllers in the Angular app. I am using Visual Studio and Cordova to write the app. I have come up with a solution for getting the token from Moodle, storing it using jstorage, and displaying it on the various panes of the single-page mobile app. With thanks to many other StackOverflow answers

Search engine indexing of single page applications

问题 Alright so I've been writing Backbone.js apps for over a year now and I love the framework model. I've learned how to avoid all the pitfalls and such, but there's one area I'm still quite weak as a single page app developer: how to SEO a public facing app. I'm working on a blog project, and the easiest solution to my mind is to have a server generated list of all blog entries visible as a link from the /blog section that is rendered on page load, and to ensure that when hitting a /blog/:id

What is client side MVC and how is it implemented in JavaScript?

阅读更多关于 What is client side MVC and how is it implemented in JavaScript?

Recently gone through many articles explaining single page application. But i am very much confused about the architecture or rather how it works. There is some thing new called client side MVC implemented by using javascript. Till now i had seen server side MVC architecture. What is this client side MVC? Where does the client side MVC files are hosted. Is it hosted along with server files similar to typical web application. What is the role of server side java script like node.js. What is the flow from end to end. Client side MVC means that a MVC framework is built entirely on the client side

Durandal Multiple Master Pages

阅读更多关于 Durandal Multiple Master Pages

问题 I am working on a SPA that I would like to use multiple master views. Here is my use case: I have a user that has a profile page. Within that profile page I would like to be able to display a couple of different views, ie. details, works, contact info, etc. I need to be able to deep link to each of these views. Each of these views must display the basic user data from the master layout view. It is my understanding that I should be using compose for this and I have a bit of code that seems to

Html5 pushstate Urls on ServiceStack

阅读更多关于 Html5 pushstate Urls on ServiceStack

At the moment we're using a default.cshtml view in the root of ServiceStack to serve our AngularJS single-page app. What I'd like to do is enable support for html5 pushstate (so no hash in the URL), but the only examples I've found so far involve a dependency on MVC with a wildcard route, and pushing the ServiceStack infrastructure to a /api subroute. We can't take the MVC dependency, so I think we need for accept:text/html requests we need to accept any url and serve up our root application. I'd be happy to remove the default HtmlFormat extension or override it (we could still use it's
