angular - ‘local' 的所有声明在 ionic 2 中必须具有相同的修饰符

Question

当我使用 local:storage 变量时出现此错误。我只是想注意到这是在一个小时之前发生的。在此之前它运作良好。

当我尝试通过“ionic serve”运行应用程序时显示此错误。

这是我的服务

import { Injectable } from '@angular/core';
import { Http } from '@angular/http';
import 'rxjs/add/operator/map';
import {NavController} from "ionic-angular";

import { Storage } from '@ionic/storage';
/*
  Generated class for the Myservice provider.

  See https://angular.io/docs/ts/latest/guide/dependency-injection.html
  for more info on providers and Angular 2 DI.
*/
@Injectable()
export class MyService {

  public local:Storage;
  public getsession: any;


  constructor(public http: Http,private local: Storage,private navCtrl:NavController) {
    this.local=new Storage();

  }
  postLogin(data){
    let link = "http://adirzoari.16mb.com/login.php";
    return this.http.post(link,data)
        .map(res => res.json())
  }
  checkToken(){
    return this.getsession =this.local.get('token');

  }
  getData(){
    let link = "http://adirzoari.16mb.com/selectNotes.php";
    return this.http.get(link)
        .map(res=>res.json())
  }
  postInsert(data){
    let link="";
    return this.http.post(link,data)
        .map(res=>res.json())
  }
  postUpdate(data){
    let link="";
    return this.http.post(link,data)
        .map(res=>res.json())
  }
  postDelete(data){
    let link = "http://adirzoari.16mb.com/deleteNotes.php";
    return this.http.post(link,data)
        .map(res => res.json())
  }
}

此外，我收到这个错误

Answer 1

这是因为您还将 local 声明为 public local:Storage; 并且还在构造函数中声明为 private，如下所示:

constructor(public http: Http,private local: Storage,private navCtrl:NavController) {

修复

删除public local:Storage;
