I have problem regarding LinkedIn Authentication in Angular2 my code is.

import {Component , OnInit , NgZone} from 'angular2/core';
import {HTTP_PROVIDERS} from 'angular2/http';
import {ROUTER_DIRECTIVES , Router} from 'angular2/router';

declare var IN : any;

@Component({
  directives : [ROUTER_DIRECTIVES],
  selector : '.main',
  providers : [HTTP_PROVIDERS],
  templateUrl : './app/registration/employee.reg.html'
})

export class EmployeeRegistrationComponent implements OnInit{

 constructor(private zone : NgZone){
    this.zone.run(() => {
        $.proxy(this.OnLinkedInFrameworkLoad, this);
    });
}

ngOnInit(){
    var linkedIn = document.createElement("script");
    linkedIn.type = "text/javascript";
    linkedIn.src = "http://platform.linkedin.com/in.js";
    linkedIn.innerHTML = "\n"+
        "api_key: **********\n" +
        "authorize: true\n" +
        "onLoad:" + this.OnLinkedInFrameworkLoad ;
    document.head.appendChild(linkedIn);

    var script = document.createElement("script");
    script.type = "in/Login";
    document.body.appendChild(script);
}

OnLinkedInFrameworkLoad = () => {
    IN.Event.on(IN, "auth", this.OnLinkedInAuth);
}

OnLinkedInAuth = () => {
    IN.API.Profile("me").result(result => this.ShowProfileData);
}

ShowProfileData(profiles) {
    console.log(profiles);
    var member = profiles.values[0];
    var id=member.id;
    var firstName=member.firstName;
    var lastName=member.lastName;
    var photo=member.pictureUrl;
    var headline=member.headline;

    //use information captured above
   }

}

控制台抛出错误:angular2-polyfills.js:1250 Uncaught Error: Could not execute 'function () {'. Please provide a valid function for callback.

推荐答案

这对我有用:

import { Component, OnInit, NgZone } from '@angular/core';

   export class RegistrationComponent implements OnInit{

constructor(private ngZone: NgZone) {
       window['onLinkedInLoad'] = () => ngZone.run(() => this.onLinkedInLoad());
        window['displayProfiles'] = (profiles) => ngZone.run(() => this.displayProfiles(profiles));
        window['displayProfilesErrors'] = (error) => ngZone.run(() => this.displayProfilesErrors(error));
    }

    ngOnInit() {
              var linkedIn = document.createElement("script");
                        linkedIn.type = "text/javascript";
                        linkedIn.src = "http://platform.linkedin.com/in.js";
                        linkedIn.innerHTML = "\n" +
                           "api_key: ****\n" +
                           "authorize: true\n" +
                           "onLoad: onLinkedInLoad\n"+
                           "scope: r_basicprofile r_emailaddress";
                        document.head.appendChild(linkedIn);
                        var script = document.createElement("script");
                        script.type = "in/Login";
                        document.body.appendChild(script);
                }

                public onLinkedInLoad() {
                        IN.Event.on(IN, "auth", this.onLinkedInProfile);
                }

                public onLinkedInProfile() {
                            IN.API.Profile("me")
                                .fields("id", "firstName", "lastName", "email-address")
                                .result(this.displayProfiles)
                                .error(this.displayProfilesErrors);
                }
                public displayProfiles(profiles) {
                    console.log(profiles);
                }
                public displayProfilesErrors(error) {
                        console.debug(error);
                }
                //Invoke login window with button
                public liAuth() {
                   IN.User.authorize(function () {
                            console.log('authorize callback');
                   });
                }   
            }
