Question

那里没有很多关于hapi及其auth-cookie插件的例子，但是到目前为止我在尝试确保路由时已经有了。请注意，我见过的大多数示例都使用的是较旧版本的hapi，它似乎并不适用于这种情况，我希望我只是遗漏了一些简单的东西：

var Hapi = require('hapi');
var Mongoose = require('mongoose');

Mongoose.connect('mongodb://localhost/rfmproducetogo');

var server = new Hapi.Server(8080, "localhost");

server.pack.register([{
    plugin: require("lout")
}, {
    plugin: require('hapi-auth-cookie')
}, {
    plugin: require("./plugins/togo")
}, {
    plugin: require("./plugins/auth")
}], function(err) {
    if (err) throw err;
    server.auth.strategy('session', 'cookie', {
        password: 'shhasecret',
        cookie: 'wtfisthisfor',
        isSecure: false,
        redirectTo: false
    });
    server.start(function() {
        console.log("hapi server started @ " + server.info.uri);
    });
});

在我的togo插件中，我将此路由设置为使用会话

exports.create = function(plugin) {
    plugin.route({
        method: 'POST',
        path: '/togo/add',
        handler: function(request, reply) {
            produce = new Produce();
            produce.label = request.payload.label;
            produce.price = request.payload.price;
            produce.uom = request.payload.uom;
            produce.category = request.payload.category;

            produce.save(function(err) {
                if (!err) {
                    reply(produce).created('/togo/' + produce._id);
                } else {
                    reply(err);
                }

            });
        },
        config: {
            auth: 'session'
        }
    });
};

我看到的错误是：

/home/adam/Projects/bushhog/node_modules/hapi/node_modules/hoek/lib/index.js:421
    throw new Error(msgs.join(' ') || 'Unknown error');
          ^

运行节点0.10.28，hapijs 6.x，hapi-auth-cookie 1.02

当您尝试在实际可用之前使用身份验证策略时，会出现此问题。

您已经通过将功能拆分为具有给定范围的单个小插件来完成良好的应用程序设置。

更新：这是针对该问题的专门教程，how to fix „unknown authentication strategy“

设置身份验证的好方法和依赖身份验证的插件是创建一个额外的＆＃34; auth插件＆＃34;这会添加您想要的策略，并可以用作其他插件中的依赖项。

hapi auth plugin example

exports.register = function (server, options, next) {

  // declare/register dependencies
  server.register(require('hapi-auth-cookie'), err => {

    /**
     * Register authentication strategies to hapi server
     *
     * We’re using hapi-auth-cookie plugin to store user information on
     * client side to remember user data on every website visit
     *
     * For sure, we could and will add more authentication strategies.
     * What’s next: JWT (we highly welcome pull requests to add JWT functionality!)
     */
    server.auth.strategy('session', 'cookie', {
      password: 'ThisIsASecretPasswordThisIsASecretPassword',
      cookie: 'hapi-rethink-dash',
      redirectTo: '/login',
      isSecure: false
    });

    server.log('info', 'Plugin registered: cookie authentication with strategy »session«')

    next()

  })

}

exports.register.attributes = {
  name: 'authentication',
  version: '1.0.0'
}

在/plugins/togo中，您将authentication plugin设置为依赖项（使用server.dependency([array-of-deps])），这意味着hapi首先注册auth插件，然后注册依赖插件。

您可以像这样注册插件：

server.register([{
    plugin: require('./plugins/authentication')
}, {
    plugin: require("./plugins/togo")
}], function(err) { 
  // handle callback
})

检查hapi-rethinkdb-dash以获取详细示例。

希望有所帮助！

请记住，如果你在像Marcus Poehls这样的插件中使用server.dependency，你还需要注册该依赖

server.register([{
    plugin: require('hapi-auth-cookie')
},{
    plugin: require('./plugins/authentication')
}, {
    plugin: require("./plugins/togo")
}], function(err) { 
  // handle callback
})

hapi-auth-cookie无法加载会话策略
