Not sure if I’m still missing something but pretty sure I’m correctly importing HttpModule:
app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { HttpModule } from '@angular/http';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { IonicStorageModule } from '@ionic/storage';
import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { MyApp } from './app.component';
import { CredentialsProvider } from '../providers/credentials/credentials';
import { ApiProvider } from '../providers/api/api';
import { BasePage } from '../pages/base';
@NgModule({
declarations: [
MyApp,
BasePage
],
imports: [
BrowserModule,
HttpModule,
IonicModule.forRoot(MyApp),
IonicStorageModule.forRoot()
],
bootstrap: [IonicApp],
entryComponents: [
MyApp
],
providers: [
StatusBar,
SplashScreen,
{provide: ErrorHandler, useClass: IonicErrorHandler},
CredentialsProvider,
ApiProvider
]
})
export class AppModule { }
api.ts
import { CredentialsProvider } from '../credentials/credentials';
import { Observable } from 'rxjs/Observable';
import { Injectable } from '@angular/core';
import {
Http,
ConnectionBackend,
RequestOptions,
RequestOptionsArgs,
Response,
Headers
} from '@angular/http';
@Injectable()
export class ApiProvider extends Http {
private authHeader: string;
constructor(
public backend: ConnectionBackend,
public requestOpts: RequestOptions,
private credentialsProvider: CredentialsProvider
) {
super(backend, requestOpts);
credentialsProvider.getStoredCredentials().then((val: string) => {
this.authHeader = val;
});
console.log('Hello ApiServiceProvider Provider');
}
request(url: string, options: RequestOptionsArgs): Observable<Response> {
this.setContentTypeHeader(options.headers); // TODO: May neet to add case-by-case
return super.request(this.credentialsProvider.environment.api + url, options);
}
private setContentTypeHeader(headers: Headers): void {
headers.set('Content-Type', 'application/json');
}
}
