如何将queryparameters转换为angular4中的字符串

我的目标如下：

 const navigationExtras: NavigationExtras = {
  queryParams: {
    serviceName: 'someName',
    serviceId: 5,
    businessAreaId: 1,
    servicePhaseVersionId: 5,
    versionDescription: 'Version 1',
    phaseName: 'SomePhase',
    mode: 1

this.router.navigate(['someUrl/'], navigationExtras);

我的导航方式如下：

 const navigationExtras: NavigationExtras = {
  queryParams: {
    serviceName: 'someName',
    serviceId: 5,
    businessAreaId: 1,
    servicePhaseVersionId: 5,
    versionDescription: 'Version 1',
    phaseName: 'SomePhase',
    mode: 1

this.router.navigate(['someUrl/'], navigationExtras);

在浏览器中导航后，我看到如下URl：

http://localhost:4000/someUrl/version?serviceName=someName&serviceId=5&businessAreaId=1&servicePhaseVersionId=5&versionDescription=Version%201&phaseName=SomePhase&mode=1

是否有可能获取带有浏览器URL或以下参数的字符串

'serviceName=someName&serviceId=5&businessAreaId=1&servicePhaseVersionId=5&versionDescription=Version%201&phaseName=SomePhase&mode=1'

使用参数

注入依赖项：

激活的外部

因为params返回一个可观察的，所以您需要订阅它来获取参数

 constructor(private _activateRoute: ActivatedRoute) {
        this._activateRoute.params.subscribe((params) => this.activateComponent(params));
   }

您想获得带参数的整个字符串还是单个参数？整个字符串与上一个代码示例完全相同
