【原创】实现POST方法往代理内传输大容量数据

楼主ChinaMake2008（Notes）2005-07-02 10:48:34 在企业开发 / Lotus 提问

昨天终于在朋友以及自己的努力下完成了POST方式的中文数据传输，实在非常开心，在此我特地来发贴分享一下我的成果，呵呵～～希望大家喜欢
第一、介绍一下我所用的语言为javascript、java
第二、POST调用代理的模式，代码如下：
if(document.all.ACTIVITYOS.value == "提案申请")
{
var DataString = CaseCheckNullData();

/*----------------------------------------------------------------------------------------------------------------*/
/*主要用于定义ActiveX控件Microsoft.XMLHTTP进行数据上传
/*----------------------------------------------------------------------------------------------------------------*/
try
{
var XmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
catch(E){}

if(DataString != "")
{
/*----------------------------------------------------------------------------------------------------------------*/
/*主要用于上传数据
/*----------------------------------------------------------------------------------------------------------------*/
if(XmlHttp == null)
{
alert("你未曾开启ActiveX控制，请迅速与资讯联系！");
}
else
{
/*-----------------------------------------------------------------------------------------------------------*/
/*主要用于数据上传
/*-----------------------------------------------------------------------------------------------------------*/
var url = "http://192.168.1.10/data3/applicat.nsf/ShowMessage?OpenForm";

XmlHttp.Open('POST',"http://192.168.1.10/data5/ResCaseA.nsf/ResWrDataIn?OpenAgent",false);
XmlHttp.Send(escape(DataString));

window.showModalDialog(url,"","dialogWidth:300px;dialogHeight:1px;center:yes;status:no;help:no");

var ResVal = XmlHttp.responseText.split("_|_");
document.all.CaseNum.value = ResVal[1];
}

LWFActivityComplete("",true,"","")
/*----------------------------------------------------------------------------------------------------------------*/
}
}
从上面的代码可以清晰的看到利用XmlHttp的POST方式调用代理，然后利用SEND来进行数据的传输，不过由于是中文，传输前需要用函数escape进行数据编码，然后只需要在代理当中进行解码就可以获取到相应的中文，在文档之中需要加入CGI域Request_Content，用于接受send过来的数据

最后说明一下如何你想数据量传输的很大需要在服务器端配置一下POST的容量大小呵呵～～

解码好像可以这样吧：
在web上，通过js函数，对中文的内容进行编码
在服务器中，直接使用公式@urldecode(.......)进行解码Top

楼主，为啥不用java.net.URLDecoder，这个类，而要自己写？Top

13 楼tnda（虎头）回复于 2005-07-22 14:20:10 得分 0

哦，我测试了下，发现楼主是用js的UNCODE编码加密算法，和java.net.URLEncoder不一样
所以不能使用java.net.URLDecoder解密

不过楼主的解密方法有问题，
如果源码里面包括“/”字符，则无法解密

ss = "中文1234 abcd[]()<+>,.~\\aaa/";
ss1 = escape(ss)
document.forms[0].aaaa.value = ss1;

这个是JS加密后的字符：%u4E2D%u65871234%20abcd%5B%5D%28%29%3C+%3E%2C.%7E%5Caaa/
说明JS加密时，“/”是不加密的，

而使用楼主的类解密时：会丢失“/”这个字符，
解码后的字符为：中文1234 abcd[]()< >,.~\aaa

如果用楼主自己的加密算法加密，再解密，则没有问题，

我发现你使用
//String DataXml = udoc.getItemValueString("Query_String_Decoded");
也完全可以自动解码，而没有任何错误，不需要自己写解码算法，

不知道你为啥不用，也许你认为URL的长度有限制而不好用吧
