求助，怎样连接上后，让服务端发起向远端的请求，然后把响应发回来呢
我已经明白
var options = { host: ‘XXX.X.X.XX’, port: 7379, path: ‘/GET/soscount’, method: ‘get’ }; http.get(options, function(res) { console.log("Got response: " + res.statusCode); res.on(‘error’, function(e) { console.log("Got error: " + e.message); }).on(‘data’, function (chunk) { console.log('BODY: ’ + chunk); }) });
也会建立
var http = require(‘http’); http.createServer(function(req,res){ res.writeHead(200,{‘Content-Type’:‘text/html’}) res.write(’<h1>node</h1>’) res.end(’<p>hello</p>’) }).listen(4000); console.log(“httpServer is listening at port 4000”)
我现在想 连接到server后，发起那个get请求，之后把数据返回给这个连接的response 应该怎样写呢？

谢谢你的回答啊。。 是这个意思么：
var http = require('http');
http.createServer(function (req, resq) {
var options = {
host : '111.1.3.68',
port : 7379,
path : '/GET/soscount',
method : 'get'
};
http.get(options, function (res) {
console.log("Got response: " + res.statusCode);
res.on('error', function (e) {
console.log("Got error: " + e.message);
}).on('data', function (chunk) {
console.log('BODY: ' + chunk);
}).end(
resq.writeHead(200, {
'Content-Type' : 'text/html'
})
resq.write('<h1>node</h1>')
resq.end('<p>hello</p>'))
});
}).listen(4000);
console.log("httpServer is listening at port 4000")
然后resq他找不到啊。。。
var http = require('http'),
q = require('querystring');
http.createServer(function (req, res) {
//创建geo 经纬度, 用于取Google 地图
var url=["/maps/geo?q="
,q.parse(req.url)["long"]
,","
,q.parse(req.url)["lat"]
,"&output=json&sensor=false"].join(""),
//创建options
options={host:"maps.google.com" ,path:url};
//log
console.log("url:",options.host+options.path);
console.log("requrl:",req.url);
//服务端发出请求get
http.get(options,function(response){
//console.log("hi",response);
res.writeHead(200, {'Content-Type': 'text/plain'});
var pageData = "";
response.setEncoding('utf8');
//接受数据,保存
response.on('data', function (chunk) {
pageData += chunk;
});
//数据接收完毕, 输出到客户端
response.on('end', function(){
res.write(pageData);
res.end();
});
});
}).listen(80);
