nodejs hapiJs：发送，接收来自客户端的数据

我有以下文件; client.js和server.js。 我想发送数据到我的服务器，使用Ajax。 我设法发送search的用户名，但是在服务器上接收到的域未定义。 我不确定是否在客户端或服务器端丢失了某些东西？ 在服务器端，我的函数应该是一个通用的函数，允许它接收任何域，并在该域上的请求问题。 任何人都可以帮忙吗？

Cliente：

$(document).ready(function(){ console.log("Ready!"); var domains=[ ]; //pass domain names into array for easier iteration domains.push($(".facebook").find("a").text()); domains.push($(".github").find("a").text()); domains.push($(".twitter").find("a").text()); domains.push($(".instagram").find("a").text()); domains.push($(".pinterest").find("a").text()); console.log(domains); $("#searchbutton").on('click', function(event){ var username = $("#searchname").val().trim(); // store value from searchbox console.log(username); if(username === ""){ event.preventDefault(); } if(username){ var newhtml = "<p>"; newhtml += username; newhtml += "</p>"; $(".username").html(newhtml); $(".username").remove("newhtml"); var domainCheck = function(domainName){ $.ajax({ url: "/"+username, type: "get", data: {domainName: domainName, username: username}, success: function(response){ console.log(domainName); console.log(response); } }); }; //send ajax request to server for each domain name to check for username availability var len = domains.length; for(var i = 0; i<len; i++){ domainCheck(domains[i]); console.log(domains[i]+'\n'); } } }); }); 

服务器：

 var Hapi = require('hapi'); var request = require('request'); var server = Hapi.createServer('localhost', 8080); var routes =[ { path: "/", method: "GET", handler: function (req, reply){ console.log("Home page loaded and runnning!"); reply.file('index.html'); } }, { path: '/{username}', method: 'GET', handler: function (req, reply){ // this is not working. the domain name is not being received from the client side. instead its passing undefined! request('http://www.'+ req.domain.domainName +'.com/' + req.params.username, function(error, response, body){ console.log("Request received"); console.log(response.statusCode); if ( response.statusCode === 404 ) { console.log( "Username " + req.params.username + " is available on " + req.domain.domains); reply({"available":"yes"}); } if ( response.statusCode === 200 ) { console.log( "Username " + req.params.username + " is already taken on " + req.domain.domains); reply({"available":"no"}); } }); } }, { method: 'GET', path: '/static/{param*}', handler: { directory: { path: 'static' } } } ]; server.route(routes); server.start(function() { console.log("Server started", server.info.uri); }); module.exports = server;

将req.query.domainName更改为req.query.domainName 。 当你访问请求数据时，你需要指定它是否在查询，有效载荷等等
