## Angular HTTP 通信课程概述 本课程深入讲解 Angular 的 HTTP 通信功能，这是浏览器与服务器通信的主要方式。Angular 的 HTTP 库极大地简化了 XHR 和 JSONP API 的应用。几乎所有 Angular 应用都需要通过 HTTP 请求与后端 Web API 进行数据检索、保存、更新和删除操作。 **课程内容亮点：** * **基础与进阶特性：** 涵盖 Angular HTTP 的基础知识及高级应用。 * **新版 HTTP Client 模块：** 介绍全新的 HTTP Client 模块，包括： * HTTP GET 请求示例。 * 增强的类型安全。 * 基于不可变性的 HTTP 请求参数和 Headers API。 * HTTP PUT, PATCH, POST, DELETE 方法的应用。 * RESTful JSON 的相关指南。 * **HTTP Client 服务核心功能：** * 请求类型化响应对象。 * 简化的错误处理机制。 * 请求和响应的拦截。 * **RxJS 与 Angular HTTP：** 重点讲解 RxJS 及其在 Angular HTTP Client 中常用的操作符。 * **Progress HTTP Events：** 详细介绍 HTTP Client 支持的“Progress HTTP Events”这一重要新用例。 **课程价值：** 新的 Angular HTTP Client 相较于之前的客户端版本是前端开发领域的一大进化，它更加用户友好，并能有效提升代码的类型安全性。通过本课程的学习，你将能够熟练运用 Angular 实现高效、安全且健壮的 HTTP 通信。
HTTP is the primary protocol for browser and server communication. The Angular HTTP library simplifies application programming with the XHR and JSONP APIs. Almost all Angular applications need to make HTTP requests to a back-end web API to retrieve, save, update, and delete data. This course teaches basic, as well as advanced features of Angular HTTP. This course also covers an introduction to the new HTTP client module, example of an HTTP GET, improved Type Safety, HTTP Request Parameters (Immutability-based API), HTTP Headers (Immutability-based API), HTTP PUT, PATCH, POST, DELETE, some REST Guidelines (specific to RESTful JSON) for using the multiple HTTP methods, and much more. It also goes over the major features of the HTTP client service provided by angular such as the ability to request typed response objects, streamlined error handling, request and response interception.In addition, it teaches how to use RxJS, and the RxJS operators that are most common when working with the Angular HTTP client. A significant part of this course is dedicated to teaching how to work with another new use case that is supported by the HTTP client; Progress HTTP Events.The new Angular HTTP Client is a great evolution when compared to the previous HTTP client in the front-end world of wed development. It's more user-friendly and helps to improve the type safety of our code.
