多个用户模型的回送通行证-facebook

标签： javascript node.js passport.js loopbackjs passport-facebook

我正在使用护照来通过Facebook验证我的应用程序的用户身份。 在我的应用程序中，我有2个不同的用户：客户和专业人员（转换为“专家”）。

我遵循Loopback docs来实现loopback-component-passport软件包和passport-facebook，并使其对我的客户有效。

因为我使用自定义用户模型，所以我遵循了SO Post的方法来修复该问题（注意：我仍然使用内置的AccessToken模型）。

Angular前端

我使用Angular前端。为了将用户重定向回我的前端，我创建了一个如下所示的启动脚本：

'use strict';

module.exports = function(app) {
  var router = app.loopback.Router();
  var cookieParser = require('cookie');

 // Redirect user to page set in env.APP_HOST
 router.get('/auth/customer/success', function(req, res, next) {
     const cookie = req.headers.cookie;
     var result = cookieParser.parse(cookie);
     res.redirect(process.env.APP_HOST + '/auth/facebook/?token=' + 
         result['access_token'] + '&id=' + result['userId'] + 
         '&err=&fbsr=');
 });

 router.get('/auth/expert/success', function(req, res, next) {
     const cookie = req.headers.cookie;
     var result = cookieParser.parse(cookie);
    res.redirect(process.env.APP_HOST + '/expert/auth/facebook/?token=' 
        + result['access_token'] + '&id=' + result['userId'] + 
        '&err=&fbsr=');
 });

 app.use(router);
};

我通过客户身份验证后，应重定向到https://example.com/auth/customer/success 当我通过专家/专家身份验证时，应重定向到https://example.com/auth/expert/success。

设置第二本护照-facebook

我必须同时在server.js中为客户和专业/专家加载配置。我创建了2个provider.json文件（ providers.customer.json 和 provider.professional.json ），其中包含它们的特定信息。

这是我加载这两种配置的方式（可能有点混乱）：

var passportCustomer = require('loopback-component-passport');
var PassportConfiguratorCustomer = passportCustomer.PassportConfigurator;
var passportConfiguratorCustomer = new PassportConfiguratorCustomer(app);
var passportProfessional = require('loopback-component-passport');
var PassportConfiguratorProfessional = passportProfessional.PassportConfigurator;
var passportConfiguratorProfessional = new PassportConfiguratorProfessional(app);

// Setup passport configuration
var passportCustomerConfig = {};
var passportProfessionalConfig = {};
try {
    passportCustomerConfig = require('./providers.customer.json');
    passportProfessionalConfig = require('./providers.professional.json');
} catch(err) {
    console.log('Please configure the passport strategy in providers.customer.json');
    console.error(err);
    process.exit(1); // Fatal error
}

// Init passport for customer
passportConfiguratorCustomer.init(false);
passportConfiguratorProfessional.init(false);

// Setup passport models
passportConfiguratorCustomer.setupModels({
  userModel: app.models.Customer,
  userIdentityModel: app.models.UserIdentityCustomer,
  userCredentialModel: app.models.UserCredentialsCustomer
});

passportConfiguratorProfessional.setupModels({
  userModel: app.models.Professional,
  userIdentityModel: app.models.UserIdentityProfessional,
  userCredentialModel: app.models.UserCredentialsProfessional
});

// Configure passport for customer
for(var s in passportCustomerConfig) {
    var c = passportCustomerConfig[s];
    c.session = c.session !== false;
    passportConfiguratorCustomer.configureProvider(s, c);
}

// Configure passport for professional/expert
for(var s in passportProfessionalConfig) {
    var c = passportProfessionalConfig[s];
    c.session = c.session !== false;
    // passportConfiguratorProfessional.configureProvider(s, c);
    passportConfiguratorCustomer.configureProvider(s, c);
}

实际问题

我在Facebook中有2个不同的应用程序（1个用于客户，1个用于专业人士/专家）。当我使用localhost：3000 / auth / customer / facebook或localhost：3000 / auth / expert / facebook进行身份验证时，我看到两个应用程序都用于正确的端点。但是，无论我使用什么端点，在身份验证之后，我总是被重定向到http://example.com/expert/auth/facebook

所以我的问题是：如何解决此问题，以便将客户重定向到客户端点，并将专家/专业人士重定向到他们的专家端点？

  • 注册工作正常，我可以在数据库的客户表中找到客户，在专家表中找到专家

答案 0 :(得分：1)

因此，我能够使用PassPortConfigurator#configureProvider方法来解决此问题。我没有使用JSON文件来设置facebook身份验证，而是在JS中完成的。

var passportCustomer = require('loopback-component-passport');
var PassportConfiguratorCustomer = passportCustomer.PassportConfigurator;
var passportConfiguratorCustomer = new PassportConfiguratorCustomer(app); // Note the first letter is not a capital one

// Init passport for customer
passportConfiguratorCustomer.init(false);

// Setup passport models
passportConfiguratorCustomer.setupModels({
  userModel: app.models.Customer,
  userIdentityModel: app.models.UserIdentityCustomer,
  userCredentialModel: app.models.UserCredentialsCustomer
});

// Load configuration here instead of the JSON file.
passportConfiguratorProfessional.configureProvider('facebook-login-expert', {
  module: 'passport-facebook',
  clientID: XXX,
  clientSecret: XXX,
  callbackURL: '/auth/expert/facebook/callback',
  authPath: '/auth/expert/facebook',
  callbackPath: '/auth/expert/facebook/callback',
  successRedirect: '/auth/expert/success',
  failureRedirect: '/auth/expert/failure',
  scope: ['email'],
  failureFlash: true,
  profileFields: ['locale', 'name', 'email']
});
