Angular 从角度组件中的Json响应中提取数据

基本上我有一个角度组件，它从WEBApi得到如下响应

export class FetchDataComponent implements OnInit {

    constructor(private _httpService: Http) { }

    City: string[] = [];


    ngOnInit() {

        // city and country

        this._httpService.get('/api/City').subscribe(values => {

            this.City = values.json() as string[];

        });


    }
}

我在这里得到的答复是[“滑铁卢”，“加拿大”]

如何从上面的回答中提取城市滑铁卢？根据要求，我需要在这里做

我试图将滑铁卢存储在单独的变量中，将加拿大存储在单独的变量中。

我不确定我是否正确理解您的问题。如果你想从你的

城市

对象中得到“滑铁卢”，你可以使用

响应是字符串数组：

City: string[] = [];
var1: string;
var2: string;
ngOnInit() {    
    this._httpService.get('/api/City').subscribe(values => {
        this.City = values.json() as string[];
        this.var1 = this.City[0];
        this.var2 = this.City[1];
    });
}

City: string[] = [];
var1: string;
var2: string;
ngOnInit() {    
    this._httpService.get('/api/City').subscribe(values => {
        this.City = values.json() as string[];
        this.var1 = this.City[0];
        this.var2 = this.City[1];
    });
}

City: string[] = [];
ngOnInit() {    
    this._httpService.get('/api/City').subscribe(values => {
        this.City = values.json() as string[];
        var city = this.City.find(x => x === 'Waterloo'(please input city you want to get));
    });
}
