Are you disappointed with the traditional Java MVC frameworks such as Struts and WebWork? A large number of XML configuration files, *. do ing causes many formbeans to be written to pass page parameters? The forced Action interface makes it inconvenient for a class to process only one request.
Popular Web sites have already implemented REST-style URLs, such as Douban URLs, to show a book that is not subject. do? Id = xxx, but a natural class of http:

REST style?
It is not difficult to design and implement such an MVC framework, and then, from scratch, we examine how to implement restful URL mappings and integrate with common IoC containers such as the Spring framework. This new MVC framework is tentatively named Webwind.

DRF has a serializer concept. The function is to convert various Django Queryset and model instances to Python native formats, saving the type problems you face when writing APIs, you can also perform reverse operations. The official documentation is as follows:

Use EF and WCF to create a rest json Service. First, we need to download a Visual Studio Template named "ADO. net c # POCO Entity Generator With WCF Support ".
This is mainly used to generate the Model Class of WCF. Because the default EF Template does not have the Annotation [DataMember] or [DataContract.
Create a project in Visual Studio. Create an Entity framework EDMX. Here we have a Table,

Previously, I used AJAX to build an ajax framework.
However, ajax has a security issue, that is, it cannot perform cross-origin operations.
This morning, I took a look at fanfou.com's api!
In fact, json is javascript !! Therefore, I only need one sentence:
In this way, remote json can be read as javascript code! No ajax skills are required.
