Angular 5 http POST 调用未触发

Question

http post call is not triggering from my application. Please check the below code for http post call

getTables(): Observable<any[]> {
      return this.http.post<any[]>('http://zltstesasweb01.phs.org:7980/SASBIWS/rest/storedProcesses/Web/hsd3_hsd_pcp_try_111/dataTargets/WEBOUT','<stp><parameters><selFilter>V</selFilter></parameters></stp>',httpOptions);
}

Please check below my subscribe method

this.constantdataService.getTables().subscribe(dataobj =>{
  console.log(dataobj);
});

I am getting the below error in console.

I am not able to see the post call in my network tab as well

Answer 1

If you actually look at the network tab, the call is triggered, it just that the url is wrong.

You need to verify if the url is correct and it seems you are sending an xml as a string in the input, it should be a json, well that depends on the API.

Answer 2

The issue with 'angular-in-memory-web-api'. In-memory-web-api is blocking the real API call its searching in the localdata services. when I am adding the passThruUnknownUrl: true in configuration of app.module.ts. its started working.

@NgModule({
imports: [
  ....
  HttpClientModule,
  ...
  HttpClientInMemoryWebApiModule.forRoot(
    LocaldatasericeService,{ dataEncapsulation: false,
    passThruUnknownUrl: true }
  )
  ...
]
