NodeJs与ActionScript的GET和POST通讯

浏览数：25 / 时间：2015年06月09日

今天项目遇到一个小问题，做了个小功能，向服务端发送GET请求，但是服务端解析数据是时候报语法错误，如下：

make Request data error:SyntaxError: Error #1132: 无效的 JSON 解析输入。
Error #2044: 未处理的 error:。 text=make Request data error:SyntaxError: Error #1132: 无效的 JSON 解析输入。

很明显，引发报错的原因是服务端把这个数据当作JSON格式去解析了，但是我发送的格式是BINARY，所以导致报错了。

服务端的哥们叫我发了好几遍请求地址给他，发给他的时候他觉得GET请求的参数应该是这样的url?key=value&.....

为了证明给他看，GET请求不一定是这样子的，我自己写了一个NodeJS和ActionScript通讯的小Demo给他看。

NodeJS方代码如下：

 1 var http = require(‘http‘);
 2 var fs = require(‘fs‘);
 3 var path = require(‘path‘);
 4 var mime = require(‘mime‘);
 5 var querystring = require(‘querystring‘);
 6 var url = require(‘url‘)
 7 var cache ={};
 8 
 9 var postserver = http.createServer(function(request, response){
10     request.addListener("data", function(chunk){
11         console.log(‘Get data from : ‘+request.url + " ======= length : " + chunk.length);
12         console.log(‘Name From Request : ‘ + chunk);
13     });
14 });
15 
16 var gettserver = http.createServer(function(request, response){
17     var params = url.parse(request.url, true);
18     console.log(params);
19     response.end();
20 });
21 
22 postserver.listen("8889", function(){
23     console.log("===========Server now listenling:8889====================");
24 });
25 gettserver.listen("8887", function(){
26     console.log("===========Server now listenling:8887====================");
27 });

客户端ActionScript代码：

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
 3                xmlns:s="library://ns.adobe.com/flex/spark"
