Javascript FeatherJS/angular 4中的身份验证

我有一个典型的带有登录表单的web应用程序，我正在尝试使用FeatherJS作为后端，通过rest对用户进行身份验证。我使用角4作为前端

Angular 4中的前端身份验证服务：

import { Injectable } from '@angular/core';
import { HttpHeaders, HttpClient } from '@angular/common/http';
import 'rxjs/add/operator/toPromise';

@Injectable()
export class AuthService {
  private BASE_URL: string = 'http://localhost:3030';
  private headers: HttpHeaders = new HttpHeaders({'Content-Type': 'application/json'});
  constructor(private http: HttpClient) {}

  login(user): Promise<any> {
    let url: string = `${this.BASE_URL}/authentication`;
    return this.http.post(url, user, {headers: this.headers}).toPromise();
  }
}

后端中的authentication.js

const authentication = require('feathers-authentication');
const jwt = require('feathers-authentication-jwt');
const local = require('feathers-authentication-local');


module.exports = function () {
  const app = this;
  const config = app.get('authentication');

  // Set up authentication with the secret
  app.configure(authentication(config));
  app.configure(jwt());
  app.configure(local());

  app.service('authentication').hooks({
    before: {
      create: [
        authentication.hooks.authenticate(config.strategies)
      ],
      remove: [
        authentication.hooks.authenticate('jwt')
      ]
    }
  });
};

根据以上内容，我得到了404作为/authentication端点。我必须手动创建身份验证端点还是featherjs为我创建它？你能提供一个例子吗？

技巧是在请求正文中包含“策略”

{
  "email": "test@test.com",
  "password": "1234",
  "strategy": "local"
}

在发出请求之前，您需要对客户端进行身份验证。以下是执行此操作的示例：

const io = require('socket.io-client');
const feathers = require('@feathersjs/client');
const socketio = require('@feathersjs/socketio-client');
const authentication = require('@feathersjs/authentication-client');
const LocalStorage = require('node-localstorage').LocalStorage;

    const client = feathers();
        const socket = io('http://localhost:3030');

        const localStorage = new LocalStorage('./storage');
        client.configure(socketio(socket));
        client.configure(authentication({storage: localStorage}));

        client
            .authenticate(['jwt', 'local']).then(() => {
            console.log("Auto authenticated");
        }).catch(error => {
            console.log(error);
            client
                .authenticate({
                    strategy: 'local', email: "feathers@example.com",
                    password: "secret"
                }).then(() => {
                console.log("Authenticated using Email");
            }).catch(error => {
                console.log('Unable to authenticate to server');
                process.exit(1);
            });
        });
        client.on('authenticated', (login) => {
            console.log('Authenticated to server', login);
            client.service('task').create({
                text: 'A message from a REST client'
            }).then(() => {
                console.log("Task created");
            }).catch(error => {
                console.log("error", error);
            });
        });

为什么会提到Angular？这个问题是特定于后端的，可以通过Postman之类的工具进行调试和复制。是的，

/authentication

应该是这样工作的。仔细检查节点控制台中的auth插件是否没有错误。考虑提供（例如回购），因为羽毛包装版本很重要。

const io = require('socket.io-client');
const feathers = require('@feathersjs/client');
const socketio = require('@feathersjs/socketio-client');
const authentication = require('@feathersjs/authentication-client');
const LocalStorage = require('node-localstorage').LocalStorage;

    const client = feathers();
        const socket = io('http://localhost:3030');

        const localStorage = new LocalStorage('./storage');
        client.configure(socketio(socket));
        client.configure(authentication({storage: localStorage}));

        client
            .authenticate(['jwt', 'local']).then(() => {
            console.log("Auto authenticated");
        }).catch(error => {
            console.log(error);
            client
                .authenticate({
                    strategy: 'local', email: "feathers@example.com",
                    password: "secret"
                }).then(() => {
                console.log("Authenticated using Email");
            }).catch(error => {
                console.log('Unable to authenticate to server');
                process.exit(1);
            });
        });
        client.on('authenticated', (login) => {
            console.log('Authenticated to server', login);
            client.service('task').create({
                text: 'A message from a REST client'
            }).then(() => {
                console.log("Task created");
            }).catch(error => {
                console.log("error", error);
            });
        });
