带有参数和获取参数的角度路线

Question

A user will be clicking a link in an email like this:

do-something/doSomething?thing=XXXXXXXXXXX

How can I define the route in the router and subscribe to get params?

Currently in router I have:

    {
     path: 'do-something/:id',
     component: DoSomethingComponent
    },

In the component:

    ngOnInit() {
     this.sub = this.route
      .params
      .subscribe(params => {
       console.log(params)
      });
    }

However, the route never matches. Shouldn't ":id" consider anything after reset-password as a param?

this one i got for angular site

import { Component, OnInit }  from '@angular/core';
import { ActivatedRoute }     from '@angular/router';
import { Observable }         from 'rxjs/Observable';
import 'rxjs/add/operator/map';

@Component({
  template:  `
    <p>Dashboard</p>
    <p>Session ID: {{ sessionId | async }}</p>
  `
})
export class AdminDashboardComponent implements OnInit {

  constructor(private route: ActivatedRoute) {}

  ngOnInit() {
   //read query param
    this.route
      .queryParamMap
      .map(params => console.log(params.get('thing')););

     //read param value 
      this.route
      .paramMap
      .map((params: ParamMap) => 
                           console.log(params.get('id')));
  }
}

try like this

const appRoutes: Routes = [
  { path: 'do-something/:id', component: DoSomethingComponent, name: 'Details'}];

now navigation like

this.router.navigate( [
  'Details', { id: 'idvalue', param1: 'value1'
}]);//this you can try from code

this match

do-something/idvalue?param1=value1. //this try from browser

read query param like this

ngOnInit() {
  // Capture the access token and code
  this.route
      .queryParams
      .subscribe(params => {
          let thing = params['thing'];
      });
}

or try this

(new URL(location)).searchParams.get("parameter_name")

More than 1 hour wasted.

Both below did not work:
this.route.paramMap &
this.route.params

Only below worked:
this.route.queryParams

1.URL is like this:

http://localhost:4200/employee?tab=admin

2.Need to extract the value of query parameter tab , which is admin

3.Code that worked is:

ngOnInit() {
   this.route.queryParams.subscribe(params => {
    console.error(" ==== ", params["tab"]); // this will print `admin`
    // this.tabNameFromUrl = params["tab"];
  });
}

Hope that helps.
