Upgrade angular 4 to 7 @angular/http to @angular/common/http

问题

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

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.

About this step I need to replace from rom HttpModule and Http to HttpClientModule and HttpClient. Update from Http to HttpClient, are there any script to help like
$rxjs-5-to-6-migrate -p src/tsconfig.app.json

回答1:

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

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