Question

我正在尝试使用cordova-plugin-facebook4在离子2项目中使用本机FB登录。我在没有安装Facebook应用程序的模拟器上测试我的应用程序。我还安装了cordova应用程序内浏览器插件。但是当我运行应用程序时出现错误

Uncaught（承诺）：TypeError：无法读取属性'apply' undefined：无法读取callCordovaPlugin中未定义的属性。

我的实施受到https://ionicthemes.com/tutorials/about/ionic2-facebook-login的启发我添加了declare const facebookConnectPlugin：any;'到我的declarations.d.ts文件还是不行吗？帮助我。

这是 home.ts 的代码段。

import { Component } from '@angular/core';
import { NavController } from 'ionic-angular';
import { Facebook } from '@ionic-native/facebook';

@Component({
    selector: 'page-home',
    templateUrl: 'home.html'
})

export class HomePage {
    FB_APP_ID: number = xxxxxxxxxxxx;
    constructor(public navCtrl: NavController, private fb: Facebook) {
        this.fb.browserInit(this.FB_APP_ID, "v2.8");
    }
    doFbLogin() {
        let permissions = new Array();
        let nav = this.navCtrl;
        //the permissions your facebook app needs from the user
        permissions = ["public_profile"];
        this.fb.login(permissions).then(function(response) {
            let userId = response.authResponse.userID;
            let params = new Array();
            //Getting name and gender properties
            this.fb.api("/" + userId + "/me?fields=name,gender", params).then(function(user) {
                user.picture = "https://graph.facebook.com/" + userId + "/picture?type=large";
                //now we have the users info, let's save it in the NativeStorage
                alert(JSON.stringify(user));
            })
        }, function(error) {
            alert(JSON.stringify(error));
        });
    }
}
