我一直在谷歌上搜索几个小时,以便从我的网站上托管的客户端 js 发布到 nodejs 服务器,而不是将这些结果返回给我的客户端。
这是我想要完成的一个例子:
<html>
<head>
<script type="text/javascript">
var my_id = <?=$myuserid;?>;
$(function(){
$.ajax({
url: 'http://mydomain.com:8001/get_friends',
dataType: 'JSONP',
type: 'POST',
crossDomain: true,
data: {
id: my_id
},
success: function(data){
if(data.error===true){
alert(data.msg);
} else {
alert(data.users);
}
}
});
});
</script>
</head>
<body>
</body>
</html>
比 NodeJS 文件:
var http = require('http'),
url = require('url'),
mysql = require('mysql'),
sys = require('sys');
var client = mysql.createClient({
user: 'root',
password: 'password',
});
http.createServer(function(request, response){
client.query('USE mydatabase');
client.query(
'SELECT * FROM buddy_list WHERE user_id = "This is where I need my post to go"',
function selectCb(err, results, fields){
if(err){
throw err;
}
response.writeHead(200, { 'Content-Type' : 'application/json' });
"Here I need it to feed back results to client script."
response.end();
client.end();
})
}).listen(8001);
