Angular Http GET call pass array as params to API

Hi I'm new to angular hence got stuck at one place. I need to pass array as parameters to backend API backend API expects array of string as parameters

 const params = new HttpParams();
 const depKey = ['deploymentInprogress', 'deploymentMessage'];
 params.append('depKey', JSON.stringify(depKey));

 this.http.get(uri, { params: params })
      .pipe(
        take(1),
        catchError((error) => {
          return throwError(error);
        })
      ).subscribe(data => {

   })

The above code didn't work Need an help on this I'm not sure how we can pass array of strings as params to our backend API

Solution

  • You can do this:

    const params = new HttpParams();
 const depKey = ['deploymentInprogress', 'deploymentMessage'];
 params.append('depKey', depKey.join(', ');

 this.http.get(uri, { params: params }).....
