use*_*998 4 json dictionary typescript angular2-services
我是Typescript和javascript的新手.我的问题是:怎么做到这一点
```
{
"release": {
"ref": {},
"commits": {}
},
"debug": {
"ref": {},
"commits": {}
},
"feature": {
"ref": {},
"commits": {}
},
"hotfix": {
"ref": {},
"commits": {}
}
}

使用接口使用Typescript映射它
export interface IRepo {
branches: IBranch; // how to make branches a of type string: IBranch dictionary?
}
将有未知数量的属性,如调试,发布等,我想在IRepo实例中将它们保留为字典
我正在使用它来获取数据:
```
getRepo() : Observable<IRepo> {
if (!this.repo) {
return this.http.get(this._baseUrl + 'repo.json')
.map((res: Response) => {
this.repo = res.json();
return this.repo;
})
.catch(this.handleError);
} else {
return this.createObservable(this.repo);
}
}

你有一张地图,从一些已知 string的结构到已知结构的对象(有ref commits).只需使用字符串索引器:
interface BranchByName {
[branchName: string]: {
ref: any;
commits: any;
}
}
