home.component.ts

'我正在尝试在 html 页面中匹配 firebase 数据库中的类型和显示数据存储，任何人都可以解决这个错误。两天以来，我一直在努力解决这个错误。

import { Component, OnInit } from '@angular/core';
import { HttpService } from 'src/app/http.service';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent  implements OnInit{

  constructor(private http:HttpService) { }

  users : any[] =  [
   
  ];

    Oncreateuser(uname:any,fame:any){
      this.users.push({
        name:uname.value,
        name2:fame.value

      })

      uname.value = ""
      fame.value = ""  
  }

  save(){
    this.http.saveitems(this.users).subscribe(
      (Response) => console.log(Response),
      (err) => err
    )
    alert('saved to firebase Database')

  }

  onremoveitem(item:any){
    this.users.splice(item, 1)
  } 
ngOnInit(){}

fetchproduct(){
  
 this.http.fetch().subscribe((Response)=>{
   console.log(Response)

 },(err)=>console.log(err))
 
 }
}

Answer 1

请更改此行

this.http.fetch()
 .subscribe(Response=>{this.users = Response})

到

this.http.fetch()
 .subscribe((Response:any)=>{this.users = Response})

Answer 2

只需声明以下内容：

users: any = [];

而不是这个：

users: any[] = [];

“对象”类型可分配给很少的其他类型。您是想改用“any”类型吗？类型“对象”缺少以下属性
