Question

有人知道如何在Angular 4中获取基本网址吗？例如：认为我有-> https://stackoverflow.com/questions/ask 但我只想得到-> https://stackoverflow.com

我试图那样做：

constructor(private http: Http, private platformLocation: PlatformLocation) {
            this.baseUrl = (platformLocation as any).location.origin;
    }

但是我遇到了这个错误：

An unhandled exception occurred while processing the request.

如果您只想获取任何路径的原点，则可以使用 ngOnInit中的window.location而不是构造函数中

ngOnInit() {
    this.baseUrl = window.location.origin
}

使用Angular 4获取基本URL
