SOAP 和 WSDL 之间的区别

1. 简单对象访问协议(SOAP)：
它是一种基于 XML 的网络协议，用于在节点之间交换结构化数据。它的架构中有 4 层：Header、Body、Envelope 和 Fault。它在 HTML 和 SMTP 等应用层协议之上工作，用于符号和传输。它比 WSDL 更具支持性，因为它具有三个重要特征：独立性、中立性和可扩展性。

2. Web 服务描述语言 (WSDL)：
它由 IBM 和 Microsoft 共同开发，并于 2007 年 6 月 26 日由 W3C 确定。它是基于 XML 的接口定义语言，用于描述 Web 服务功能。它的架构中包含三个主要元素：类型、绑定和操作。通常，典型的 WSDL 定义了与基于 XML 的服务的实现和通信过程。

SOAP 和 WSDL 的区别：

S.No.	SOAP	WSDL
1.	It is XML based messaging protocol.	It is XML based interface definition language.
2.	It consists of four layer in its architecture : Header, Body, Envelope and Fault.	It consists of three main elements in its architecture : Types, Binding and Operations
3.	It provides full support to most of the protocols like HTTP, SMTP, etc.	It does not support most of the protocols like SOAP.
4.	It is slower sometimes in performance in comparison to WSDL.	It is faster in performance in comparison to SOAP.
5.	It is simple than WSDL due to easy level of coding.	It is more complex as it has advanced level of coding.
6.	It provides high security as it has different layers of security.	While it is less secured as compared to SOAP.
7.	It is far good in extensibility than WSDL.	It is less extensible than SOAP.
