二、Rest

三、Soap VS Rest

Reference:

--------------------

## 一、Soap ##

Soap (*Simple Object Access Protocol*) is a messaging protocol specification for exchanging structured information in the implementation of web services in the computer networks.

Therefore, (as soap is a protocol) it imposes some build-in rules that can add complexity and overhead, and also lead to long page load times.

The advantage of soap is safety. It supports not only SSL protocol (Secure Sockets Layer)(端到端加密), but also WS-Security protocol (WS = web services) which adds some enterprise security features.

In addition, it build-in the ACID characteristic of database to ensure the consistency and reliability of transactions. This is the reason why banks and payment system use soap.

## 二、Rest ##

Rest (Representational state transfer) is a set of web API architecture principles (or style) which suitable for lightweight web services and mobile applications.

The advantage of rest api is more flexible and easy to use.
