Web Service is a service that is a mechanism for exchanging data, provides raw information, and is difficult for most users. The web service is used by sites and applications. These applications analyze data before returning their end user.

Let's look at examples. To get weather forecast data, the ABC mobile application needs to take information from a specific resource, it can be a web service that provides weather data for different areas of the country.

Identically, in order to receive data about promotions, the ABC mobile application must also contact the web service providing this data. The data will be processed before being displayed in the mobile application. Web Service often provides raw data that is difficult to understand for most ordinary users because they are returned in XML or JSON format.

A RESTful Web Service is a Web Service that is written based on the REST (REpresentational State Transfer) structure. REST is already widely used and replaces Web Service based on SOAP and WSDL. RESTful Web Service is lightweigh and is easy to expand and maintain. The first concepts about REST were introduced in 2000 in the doctoral dissertation of Roy Thomas Fielding (HTTP co-founder). In the dissertation, he introduces in detail the restrictions and rules, as well as the methods of execution in the system for obtaining the REST system.

REST defines the rules of architecture for the design of your Web services, focuses on systematic resources, including what data format is transmitted over HTTP, is written in different languages. Due to the large number of users of web services, REST has become very popular. And over the past few years, has become very popular as service is much simpler and easier to use. In fact, REST almost replaced SOAP and WSDL all for the same reasons that it is much simpler and easier to use.

REST is a set of rules for creating a Web Service application that follows 4 basic design rules:
- Use explicit HTTP methods
- Has no condition
- Displays folder structure as URls
- Transmission of JavaScript Object Notation (JSON), XML, or both.

REST sets a rule requiring prommasters to determine their purpose through the HTTP method. Usually these goals include Retrieving data, adding data, updating data, or deleting data. Therefore when you want To complete one of the tasks above, use the following rules:

- To add data to the server, you need to use the POST method.
- To retrieve data, use GET.
- To change the state of the data or update it, use PUT.
- To cancel or delete data, use DELETE.

Note that the rules above are optional, in fact you can only use the GET method to get the data, Insert, change or delete data on the server. But REST provides the rules above that describe their name and explain the action.

Sometimes the client can determine the types of returned data that it wants (JSON or XML), these definitions are called MINE views that are attached to the request HEADER.

The following are common types of MINE used with REST service.
MIME-Type Content-Type:
- JSON application / json
- XML application / xml
- XHTML application / xhtml + xml

For example, a client sends a request for weather information for his mobile application and requires that the data be returned to him in JSON format.

Findings


Thanks to the API and http (s), as well as the JSON data exchange format, we can organize data output for mobile applications developed on Android or another program capable of receiving and processing data in the form of JSON. This is a very convenient data transfer format. Today, all applications developed for mobile phones do this.
