nop*_*ato 2 javascript node.js hapijs
我有一个用Hapi.js构建的服务器.我创建了一个插件来限制对某些本地网络IP地址的访问,如下所示:
exports.register = function (server, options, next) {
server.ext({
type: 'onRequest',
method: function (request, reply) {
console.log(request);
if (
request.info.remoteAddress.indexOf("192.") !== 0 &&
request.info.remoteAddress.indexOf("127.") !== 0
) {
return reply.view('error', {
error: "I DON'T LIKE YOU"
});
}
return reply.continue();
}
});
next();
};
exports.register.attributes = {
pkg: { "name": "localOnly" }
};

我想将此插件仅应用于"/ pathA",同时保持所有用户都可以访问"/ pathB"和"/ pathC".因此我尝试这样做:
const server = new Hapi.Server();
server.connection({ port: 8000 });
server.register(require('vision'), err => {
if (err) throw err;
server.views(/* removed for brevity */);
server.route({ method: 'GET', path: '/pathB', handler: handlerB });
server.route({ method: 'GET', path: '/pathC', handler: handlerC });
server.register(require('./plugins/localOnly.js'), err => {
if (err) throw err;
server.route({ method: 'GET', path: '/pathA', handler: handlerA });
server.start(/* removed for brevity */);
});
});

但是,似乎我的插件拦截了所有连接.谁能告诉我我做错了什么?如果你建议我做一个完整的重构,那没关系.我只是在这个阶段计划应用程序,并希望给Hapi.js一个机会.
它需要在插件中吗?如果没有,您可以使用路由级别扩展点.例如:
const restrict = function (request, reply) {
if (/^(192|127)/.test(request.info.remoteAddress)) {
return reply('Blocked');
}
return reply.continue();
};
server.route({
config: {
ext: {
onPreAuth: { method: restrict }
}
},
method: 'GET',
path: '/pathA',
handler: function (request, reply) {
reply('Hello!');
}
});

另一种使用插件的方法:
sandbox: pluginconst plugin = function (server, options, next) {
const restrict = function (request, reply) {
if (/^(192|127)/.test(request.info.remoteAddress)) {
return reply('Blocked');
}
return reply.continue();
};
// only applies to route in this plugin
server.ext('onPreAuth', restrict, { sandbox: 'plugin' });
server.route({
method: 'GET',
path: '/pathA',
handler: function (request, reply) {
reply('Hello!');
}
});
return next();
};

对于较新版本的 Hapi(当前为 v17),您将需要传递路由选项,route.options.plugins['myPluginName']例如
{
method: 'GET',
path: '/home',
options: {
plugins: {
myPluginName: true
}
}
}

ext这可以在挂钩或稍后的插件中找到onPreAuth。例如
register: async (server, options) => {
server.ext({
type: 'onPreAuth',
method: async (request, h) => {
// Exit early if the route is not configured for this route
if (!request.route.settings.plugins.myPluginName) { return h.continue }
// ... runs before the route handler ...
}
})
}

请注意,挂钩必须晚于Hapi 生命周期onRequest,因为此时尚未加载路由。如果您想访问身份验证内容,那么您将必须使用.onPostAuth
这种方法的优点是路由和插件之间松散耦合。
