Acquire all query parameters in Angular 2

Is it possible to retrieve all querystrings from the address bar in an automated way without prior knowledge of their names?

For example, I am looking to extract the following:

reports?api=Report1&from=&to=&agentId=2&status=1&fixtureId=3&gradeId=4

I have searched extensively but can only find examples that require knowing the specific querystring names.

Answer №1

While the answer may not need to be specifically about angular, one simple solution could involve:

  • window.location.search - retrieves the query string along with all parameters

  • https://www.example.com/query-converter - a helpful tool that transforms the query string into parameter objects for ease of use.

Answer №2

  • To retrieve the query string, first import ActivatedRoute:

    import {  ActivatedRoute } from "@angular/router";

  • Next, initialize it in the constructor:

    constructor(private activatedRoute: ActivatedRoute) {
     }

  • Finally, use the following code to access the query string:

        this.activatedRoute.params.subscribe(params => {
             let from = params['from'];                
        });
    

Edit

this.activatedRoute.params contains all the query strings. To retrieve a specific value, you must subscribe to it. Alternatively, you can extract the entire URL and use split(); to parse the query strings.
