我有两个功能,一个工作,另一个给我这个404错误:
/ get [object%20Object] 404(Not Found)
函数getNews给了我那个错误,我使用了console.log来查看两个函数的值,我得到了相同的结果:this.newId =" 1",所以我用两个方法调用使用"新"的ID的字符串但它只适用于onVote方法。
为什么在getNews的情况下我在请求上得到了一个Object,在onVote上我有id?
这是component.ts文件:
export class NewDetailsComponent implements OnInit
{
params = new URLSearchParams();
options = new RequestOptions({ withCredentials: true });
oneNew: New;
newId: string;
constructor(public http: Http, private activatedRoute: ActivatedRoute)
{ }
ngOnInit()
{
this.activatedRoute.params.subscribe(params =>
{
this.newId = params['id']
});
this.getNews(this.newId)
}
getNews(id: string)
{
this.params.set('id', id)
this.options.search = this.params
this.http
.get(ApiConfig.API_URL + 'news/get' + this.options)
.toPromise()
.then(response =>
{
this.oneNew = <New>response.json()
})
}
onVote(id: string)
{
this.params.set('id', id.toString())
this.options.search = this.params
this.http
.get(ApiConfig.API_URL + 'news/Vote', this.options)
.toPromise()
}
答案 0 :(得分:3)
您的获取使用+
而不是,
来添加选项:
getNews(id: string)
{
this.params.set('id', id)
this.options.search = this.params
this.http
.get(ApiConfig.API_URL + 'news/get', this.options)
.toPromise()
.then(response =>
{
this.oneNew = <New>response.json()
})
}
