Node.js,Ajax发送和接收Json
使用Ajax,我试图仅将Json数据发送到节点服务器,不进行任何处理,仅在发送时发出警报,在接收到时发出警报:
这是我的html5:具有onclick函数的简单按钮,可触发该函数使用ajax调用
<!DOCTYPE HTML><html>
<head>
<script>
function send()
{
//alert("Hello World");
$.ajax
({
type: "post",
url: "http://localhost:8000",
dataType: "json",
contentType: "application/json; charset=UTF-8",
data: JSON.stringify({name: "Dennis", address: {city: "Dub", country: "IE"}})
}).done(function ( data ) {alert("ajax callback response:" + data);
});
</script>
</head>
<body>
<button onclick="send()">Click Me!</button>
</body>
</html>
这是节点服务器的一部分:用于创建服务器并侦听某些操作
var port = 8000;var server = http.createServer();
server.on('request', request);
server.listen(port);
function request(request, response)
{
var store = '';
response.writeHead(200, {"Content-Type": "text/json"});
request.on('data', function(data)
{
store += data;
});
request.on('end', function()
{
store = JSON.parse(store);
console.log(store);
response.end(store);
});
}
没有警报被触发,所以我不认为ajax正在尝试发送信息。
回答:
在服务器端尝试此操作:
var port = 8000;var http = require("http");
var server = http.createServer();
server.on('request', request);
server.listen(port);
function request(request, response) {
var store = '';
request.on('data', function(data)
{
store += data;
});
request.on('end', function()
{ console.log(store);
response.setHeader("Content-Type", "text/json");
response.setHeader("Access-Control-Allow-Origin", "*");
response.end(store)
});
}
在客户端:
$.ajax({
type: "POST",
url: "http://localhost:8000",
crossDomain:true,
dataType: "json",
data:JSON.stringify({name: "Dennis", address: {city: "Dub", country: "IE"}})
}).done(function ( data ) {
alert("ajax callback response:"+JSON.stringify(data));
})
希望这对你有用
