在我的应用程序中，我正在调用iTunes api，当我记录响应时，响应将与[object object]一起返回。我知道这一定与api的数组结构有关。我将服务注入到组件中，如下所示：顺便说一句，我有API的proxy.conf.json文件。
服务
import { Injectable } from '@angular/core';
import { HttpClient, HttpEventType, HttpHeaders, HttpRequest, HttpResponse, HttpErrorResponse } from '@angular/common/http';
import { Observable, of, throwError } from 'rxjs';
import { catchError, retry } from 'rxjs/operators';
@Injectable({
providedIn: 'root'
})
export class ApiService {
api: string = 'api';
constructor(
private http: HttpClient,
) { }
getAll(): Observable<any> {
return this.http.get<any>(this.api)
.pipe(
catchError(this.handleError)
);
}
private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
console.log(error.error.message)
} else {
console.log(error.status)
}
return throwError(
console.log('Something is wrong!'));
};
}
component.ts
import { Component, OnInit } from '@angular/core';
import { HttpClient, HttpEventType, HttpHeaders, HttpRequest, HttpResponse } from '@angular/common/http';
import { ApiService } from '../../../services/api.service';
@Component({
selector: 'app-content',
templateUrl: './content.component.html',
styleUrls: ['./content.component.scss']
})
export class ContentComponent implements OnInit {
public results = [];
constructor(private service: ApiService) { }
private http: HttpClient
ngOnInit() {
this.getApi();
}
private getApi() {
this.service.getAll().subscribe((results) => {
console.log('JSON Response = ' + results);
})
}
}
api结构
{
"resultCount":50,
"results":[
{
"wrapperType":"track",
"kind":"song",
"artistId":271256
},
]
}
有任何想法吗？
格式正确，如果要以JSON格式查看，则需要使用JSON.stringify
this.service.getAll().subscribe((results) => {
console.log('JSON Response = ' + JSON.stringify(results));
data = results.results;
})
如果您想使用ngFor遍历元素
<li *ngFor="let dataObj of data">
{{ dataObj.wrapperType}}
</li>
