老大讓做一個簡單的Http服務器響應的東西，可是服務器端的腳本一點點也不會，ruby到現在也沒怎麼入門，想起nodejs可以做簡單快速的服務器端，就用這個瞭
其實需求很簡單就是響應URL的參數請求做一些簡單的響應，nodejs用的是javascript，方法也不是很復雜，module也不用太多，覺得挺適合的，於是就從0開始瞭
下載源碼，編譯，看sample，就開始寫瞭。
源碼如下
var sys = require("util"),
http = require("http"),url = require("url");
var fs = require("fs");
var querystring = require("querystring");
http.createServer(function(request, response) {
console.log("request version" + request.httpVersion + " request headers " + request.headers["Content-Type"] + " " + JSON.stringify(request.headers)) ;
var pathname = url.parse(request.url).pathname;
var search = url.parse(request.url).search;
var query = url.parse(request.url).query;
if(pathname == '/update.zip'){
fs.readFile("./update.zip", "binary", function(error, file) {
if(error) {
response.writeHead(500, {"Content-Type": "text/plain"});
response.write(error + "\n");
response.end();
} else {
response.writeHead(200, {"Content-Type": "application/zip"});
response.write(file, "binary");
response.end();
}
});
}else{
console.log("pathname = " + pathname+"search "+search + " query = "+ query);
response.writeHeader(200, {"Content-Type": "text/html"});
var param = querystring.parse(query);
var srcversion = param["swv"];
console.log(" param = " + param["hw"]);
// response.writeHeader(200, {"Content-Type": "text/html"});
response.write('<?xml version="1.0" encoding="UTF-8"?>');
response.write('<OTAPackage><srcVersion>'+srcversion +'</srcVersion>');
response.write('<dstVersion>'+'higher version'+'</dstVersion>');
response.write('<description><![CDATA[OTA_030_042]]></description>');
response.write('<downloadURL>https://192.168.0.154:8080/update.zip</downloadURL>');
response.write('<size>7953346</size>');
response.write('<priority>Optional</priority>');
response.write('<sessionId>007d0d21-64c8-4768-9f91-d1ae5268113f</sessionId>');
response.write('</OTAPackage>');
response.end();
}
}).listen(8080,"192.168.0.154");
sys.puts("Server running at /");
就是這麼簡單的東西，剛開始的時候response沒有寫end，結果隻能第一次響應正確，後面的全都掛瞭，http協議也不是太熟悉，具體原因也沒搞清楚，有知道的高手請告知一下，謝謝瞭
