将angular 4到7 http升级到httpclient [英] Upgrade angular 4 to 7 http to httpclient

问题描述

当前，我正在使用webpack将Angular project4升级到Angular7.
我一步一步陷入困境

Currently, I am upgrading my Angular project4 using webpack to Angular7.
I stuck in one step

从 HttpModule 和 Http 服务切换到 HttpClientModule 和 HttpClient 服务. HttpClient 简化了默认的人体工程学(您不再需要映射到json)，现在支持类型化的返回值和拦截器.

Switch from HttpModule and the Http service to HttpClientModule and the HttpClient service. HttpClient simplifies the default ergonomics (You don't need to map to json anymore) and now supports typed return values and interceptors.

关于此步骤，我需要替换

About this step I need to replace

• HttpModule => HttpClientModule
  
• Http => HttpClient
  
  要从 Http =>更新； HttpClient ，有没有什么脚本可以帮助您，例如
  $ rxjs-5-to-6-migrate -p src/tsconfig.app.json

• HttpModule => HttpClientModule
  
• Http => HttpClient
  
  For updating from Http => HttpClient, are there any script to help like
  $rxjs-5-to-6-migrate -p src/tsconfig.app.json

推荐答案

只需将您的导入内容从HttpModule更改为HttpClientModule，将Http更改为HttpClient

just change your imports from HttpModule to HttpClientModule and Http to HttpClient

import {HttpClientModule} from '@angular/common/http'
import {HttpClient} from '@angular/common/http'
