HapiJS:根据请求中传递的查询参数配置HapiJs？

Question

我的API是用Hapijs编写的。并希望基于queryParams的request对象配置API。我有一个带有端点/test的API，queryParams是type=a或type=b。如果type等于'a'，那么需要在auth中传递false，如果type等于'b'，则需要在auth中传递true。

   {
        method: 'GET',
        path: '/media',
        handler: function (request, reply) {
            TestModule.getTestData(request.query).then(reply,(err) => {
                reply(err);
            });
        },
        config: {
            description: 'This is the test API',
            notes: 'Returns a message',
            tags: ['api', 'Test'],
            auth: false // Here I need to do something.
        },
    }

，你能告诉我我能做些什么吗？

我是这样做的：

   {
        method: 'GET',
        path: '/media',
        handler: function (request, reply) {
            TestModule.getTestData(request.query).then(reply,(err) => {
                reply(err);
            });
        },
        config: {
            description: 'This is the test API',
            notes: 'Returns a message',
            tags: ['api', 'Test'],
            auth: request.query.type==='a'?false:true // Here I need to do something.
        },
    }

但是得到一个错误的ReferenceError: request is not defined。

我不认为你能做到。

为什么不只是计算response.query.type，然后根据类型重定向呢？

 {
    method: 'GET',
    path: '/media',
    handler: function (request, reply) {

        const {
         type
        } = request.query;

        TestModule.getTestData(type).then(reply,(err) => {
            if(type === a) {
             // do something
            }
            //do something else
            reply(err);
        });
    },
    config: {
        description: 'This is the test API',
        notes: 'Returns a message',
        tags: ['api', 'Test'],
        auth: false // Here I need to do something.
    },
}

您可能需要一个可选/尝试auth策略模式。详情请参见https://hapijs.com/api/#-routeoptionsauthmode。最终结果是

{
    method: 'GET',
    path: '/media',
    handler: function (request, reply) {
        if (request.query.type !== 'a' && !request.auth.isAuthenticated) {
            return reply(Boom.unauthorized('GET /media not allowed'));
        }

        TestModule.getTestData(request.query).then(reply,(err) => {
            reply(err);
        });
    },
    config: {
        description: 'This is the test API',
        notes: 'Returns a message',
        tags: ['api', 'Test'],
        auth: {
            strategy: 'your auth strategy',
            mode: 'try' // depending on your strategy. If you use a already existing strategy you probably want to use try as it will authenticate what it can and then you can still decide what to do in your handler.
        }
    }
}
