Angular 6 http.delete请求

我似乎无法让我的删除请求工作.我已经完成了所有的get请求,但现在我仍然坚持删除,似乎无法绕过它.

console.log’d URL始终正确,删除请求通过Postman正常工作.

有什么想法吗？

HTML

<button class="button button3" (click)="delTicket()"><span class="fa fa-trash"></span></button>

TS

delTicket(){
    this.id = this.route.snapshot.params.id;
    this.ticketservice.deleteTicket(this.id);
}

服务

deleteTicket(id): Observable<Ticket[]>{
    console.log(this.apiUrl + id);
    return this.http.delete<Ticket[]>(this.apiUrl + id);
}

delTicket(){
    this.id = this.route.snapshot.params.id;
    this.ticketservice.deleteTicket(this.id).subscribe((data)=>{
         console.log("success");
    });
}
