How to pass an array within a query string in HttpClient?

Question

This is my array of actors:

[\'Elvis\', \'Jane\', \'Frances\']

How to pass this array within a query strin

Answer 1

I'm using URLSearchParams instead of HttpParams.

With URLSearchParams you need to stringify your array to set it to your Params "Key-Value-Store".

import { URLSearchParams } from '@angular/http';


let params: URLSearchParams = new URLSearchParams();
params.set('actors', JSON.stringify(yourArrayHere));

I think this should work on the same way with HttpParams because both using a Key-Value mapping in the set method so give it a try.

I hope this can help you.

UPDATE:

let options = new RequestOptions({search: params});

this._http.get(url, options).map(...)

with RequestOptions you can also edit Header and other request options.
