使用简单的HttpClient:
myfunc
我得到一个如下所示的JSON对象:
this.getService.getAPI(this.profileUrl).subscribe(
data => {
this.profile = data;
}
);
所以我知道像{
"first_name": "John",
"last_name": "Doe",
"frequency": "w",
"frequency_name": "Weekly",
"delivery": "e",
"delivery_name": "Evening",
"timezone_offset": "America/Los Angeles"
}
之类的东西会将John作为值返回,但在我正在处理的特定实例中,我实际上需要获取密钥本身的值。我该怎么做?

您可以创建一个管道来操纵对象的键值对:
interface KeyValuePair {
key: string;
value: any;
}
@Pipe({
name: 'keyValuePairs'
})
export class KeyValuePairsPipe implements PipeTransform{
transform(value: Object): KeyValuePair[]{
let result: KeyValuePair[] = [];
if(!!value && value instanceof Object){
result = Object.entries(value).map(pair => ({ key: pair[0], value: pair[1] }))
}
return result;
}
}
