angular - 将 angular 4 到 7 http 升级为 httpclient

Question

目前，我正在将使用 webpack 的 Angular 项目 4 升级到 Angular7。
我卡在了一步

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

只需将您的导入从 HttpModule 更改为 HttpClientModule 并将 Http 更改为 HttpClient

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