我正在使用html页面中的ajax函数将表单数据发送到node.js服务器,如果我使用post方法我无法在控制台和警告框中看到任何内容.
如果我在ajax和app.js文件中使用get方法我会收到警告你好,但我不是app.js服务器控制台中的任何消息
app.js
var express = require('express')
, routes = require('./routes')
, manage = require('./routes/user')
, http = require('http')
, path = require('path');
var app = express();
app.post('/filter', routes.filter);
http.createServer(app).listen(app.get('port'), "172.29.59.65", function(){
console.log('Express server listening on port ' + app.get('port'));
});
index.js
exports.filter = function(req, res){
req.on('data', function (chunk) {
console.log("Received body data", chunk.toString());
//chunk is received, process it as you need
})
req.on('end', function() {
// http request is competed, send response to client
res.writeHead(200, "OK", {'Content-Type': 'text/html'});
res.end("hello");
})
};
client.html
<html>
<head>
<script>
function myFunction() {
var region=document.getElementById("region").value;
var os=document.getElementById("os").value;
alert(region+os);
var data = {};
data.region = region;
data.os = os;
$.ajax({
type: 'POST',
jsonpCallback: "callback",
datatype: 'jsonp',
data: JSON.stringify(data),
//contentType: 'application/json',
url: 'http://172.29.59.65:3000/filter',
success: function(data) {
alert(data);
console.log(JSON.stringify(data));
},
error: function (xhr, status, error){
console.log('Failure');
alert("failure");
},
});
}
</script>
</head>
<body>
<form>
<input type="text" id="region" name="region"/>
<input type="text" id="os" name="os"/>
<input type="button" value="search" class="fil_search" onclick="myFunction()"/>
</form>
</body>
</html>
我的问题是将数据发送到节点服务器并从节点服务器接收数据到html页面如何实现这一点.请帮我解决这个问题.
解决方法:
您需要一个中间件来解析正文的帖子数据.您可以尝试bodyParser.首先,您应该安装它：
$npm install body-parser
然后只需要并使用它：
var express = require('express')
, bodyParser = require('body-parser')
, routes = require('./routes')
, manage = require('./routes/user')
, http = require('http')
, path = require('path');
var app = express();
app.use(bodyParser.urlencoded({ extended: false }));
app.post('/filter', routes.filter);
http.createServer(app).listen(app.get('port'), "172.29.59.65", function(){
console.log('Express server listening on port ' + app.get('port'));
});
现在你的POST参数将存储在req.body中.
exports.filter = function(req, res){
console.log("Received body data", req.body);
res.writeHead(200, "OK", {'Content-Type': 'text/html'});
res.end("hello");
})
};
