升级 angular 4 到 7 个 http 到 httpclient

Question

目前，我正在使用 webpack 将我的 Angular 项目 4 升级到 Angular7。
我卡在了一步

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.

关于这一步我需要替换

• HttpModule => HttpClientModule
  
• Http => HttpClient
  
  对于从 Http => HttpClient 更新，是否有任何脚本可以帮助
  $rxjs-5-to-6-migrate -p src/tsconfig.app.json 或者我们需要手动编辑？

Answer 1

只需将导入从 HttpModule 更改为 HttpClientModule，将 Http 更改为 HttpClient

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