[英]Can't read properly a json file
I'm new here, and I did not find any answer to my question, or may-be I did not look up in the right way.我是新来的,我没有找到任何问题的答案,或者也许我没有以正确的方式查找。 I started my intership yesterday, and this is my first time using Angular.我昨天开始实习,这是我第一次使用 Angular。 For now, I am working on reading a json file and getting some informations, however I tested with a syntax and it worked, but the file sent by the server is a bit different.目前,我正在阅读 json 文件并获取一些信息,但是我使用语法进行了测试并且它有效,但是服务器发送的文件有点不同。 I've been testing with this json file (not the one from the company)我一直在测试这个 json 文件(不是来自公司的文件)
[
{"name": "Justine", "age": 25, "sexe": "femme"},
{"name": "Alex", "age": 23, "sexe": "homme"}
]
But if I turn [ into {, it does not work anymore但是如果我把[变成{,它就不再起作用了
{
{"name": "Justine", "age": 25, "sexe": "femme"},
{"name": "Alex", "age": 23, "sexe": "homme"}
}
Thank you in advance !先感谢您 !
EDIT: This is the code of the component编辑:这是组件的代码
import { InformationsService } from '../informations.service';
@Component({
selector: 'app-info',
template: `<h2> Liste </h2>
<ul *ngFor="let f of info">
<li>{{f.name}} <br></li>
</ul>`,
styles: []
})
export class InfoComponent implements OnInit {
public info = [];
constructor(private _info : InformationsService) { }
ngOnInit() {
this._info.getInfo().subscribe(data => (this.info = data));
}
}
The code of the service服务代码
import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Info } from './informations';
import { Observable } from 'rxjs';
@Injectable({
providedIn: 'root'
})
export class InformationsService {
private _url: string = "/assets/data/file.json";
constructor(private http : HttpClient) { }
getInfo(): Observable<Info[]>{
return this.http.get<Info[]>(this._url);
}
}
I forgot to say that my file is from an API and there is no [, only {我忘了说我的文件来自 API 并且没有 [,只有 {
You need put your data inside a root property of your json您需要将数据放在 json 的根属性中
{
"root": [
{"name": "Justine", "age": 25, "sexe": "femme"},
{"name": "Alex", "age": 23, "sexe": "homme"}
]
}
