如何在JSON字符串中选择两个测试对象并将它们映射到我的界面？

Question

Question

How can I select both test objects in my JSON string and map them to my interface called Test ? And is it possible that my property in the interface isnt called some_name ?

Problem

Im trying to map my JSON objects to the Test interface, but it does not work. The getTests in the component always returns undefined for

I guess the reason is that there is a parent named test , but res.json().data should return only the both objects test 1 and test 2 .

JSON

{"test":[{"some_name":"test 1"},{"some_name":"test 2"}]} 

Service Method

getTests() {
    return this.http.get(this.baseUrl + "/something")
        .map(res => <Array<Test>> res.json().data)
        .catch(this.handleError);
}

Component

this.myService.getTests()
    .subscribe(
        tests => this.tests = tests,
        error =>  this.errorMessage = <any>error);

Answer 1

From what I see there is no data property in the JSON content you receive.

res.json() returns an object containing a test property which is an array. You should use .map(res => <Array<Test>> res.json().test) instead to get the array.
