After which one would need to see if the resource was actually deleted. The REST architecture is based on a few characteristics which are elaborated below. These characteristics are also known as design principles which need to be followed when working with RESTful based services. This is the most fundamental requirement of a REST based architecture. It means that the server will have a RESTful web service which would provide the required functionality to the client. The server would either reject the request or comply and provide an adequate response to the client.
This is required so that server can process the response appropriately. The server should not maintain any sort of information between requests from the client. The client asks a question, the server answers it appropriately.
The client will ask another question. The server will not remember the previous question-answer scenario and will need to answer the new question independently. The Cache concept is to help with the problem of stateless which was described in the last point. Since each server client request is independent in nature, sometimes the client might ask the server for the same request again. This is even though it had already asked for it in the past. This request will go to the server, and the server will give a response.
This increases the traffic across the network. The cache is a concept implemented on the client to store requests which have already been sent to the server. So if the same request is given by the client, instead of going to the server, it would go to the cache and get the required information.
This saves the amount of to and fro network traffic from the client to the server. The concept of a layered system is that any additional layer such as a middleware layer can be inserted between the client and the actual server hosting the RESTFul web service The middleware layer is where all the business logic is created.
This can be an extra service created with which the client could interact with before it makes a call to the web service. But the introduction of this layer needs to be transparent so that it does not disturb the interaction between the client and the server. This is the underlying technique of how RESTful web services should work. Web services can be created in a variety of languages. There are two primary use situations when you to test rest api online : After developing you need to send a RESTful Web service to ensure that it is working according to your needs: that it is available in consistence with the specification and that it is responding accordingly.
While development of an application that is addressing a RESTful Web Service, for this situation it is useful to examine the access to the service and the information that is required before you start developing. While developing, you might need to call the Web service from outside your application. It will be helpful for you to find the errors when your application is showing the unexpected results while there are no logical errors detected in your code and you think that the restricted access is the connection with the Web service.
What is Rest API? Great success. Discovery is far easier in REST. You can use UDDI discoveries as well. Another reason is that it is a standard that everyone can implement and use. To read up on why standardization is important, I would suggest reading this and this it is rather funny, but really helps people grasp the concept of REST. If you're not doing some of those things -- like PUT is kind of rare and a potential security hole -- then you don't. How are we doing? Please help us improve Stack Overflow.
