webBrowser post的乱码问题 - 颜昌钢

项目:xx 之手工派单

项目介绍: xx 有两个派单形式,一是自动派单,二是手工派单.自动派单已经有程序实现,因此,需要用c#实现手工派单模块,由于xx的派单流程是从综合告警(c/s)传整个告警对象的某些设置的属性到emos(电子运维)系统(b/s),因此,在该模块中，用到了webbrowser控件.

程序处理流程介绍:

在程序中，首先读取一个配置文件的结点,查找到告警对象的某个属性,然后获取属性值(用反射),拼一个htm页面.该页面代码如下:

string s=

<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>
<html xmlns='http://www.w3.org/1999/xhtml'>
<meta http-equiv='Content-Type' content='text/html;charset=gb2312'>
<head><title>表单设置</title>
</head>
<body id='CForwardDlg' BGCOLOR='LIGHTGREY' onload='onload();'>
<form method='post' action='http://localhost/test.asp' id='ID_AlarmForm' name='ID_AlarmForm'>
<input type='hidden' name='oriAlarmId' id='ID_oriAlarmId' value='2007-8-21 21:36:42'/>
<input type='hidden' name='alarmTitle' id='ID_alarmTitle' value='HLR北京'/>
<input type='hidden' name='alarmCreateTime' id='ID_alarmCreateTime' value='www'/>
<input type='hidden' name='neType' id='ID_neType' value='beijing'/>
<input type='hidden' name='neName' id='ID_neName' value='hubeisheng'/>
<input type='hidden' name='alarmLevel' id='ID_alarmLevel' value='wuhanshi'/>
<input type='hidden' name='alarmType' id='ID_alarmType' value='12222'/>
</form>
<script language='javascript' type='text/javascript'>
function onload()
{
var tt=document.getElementById('ID_AlarmForm');
if(tt!=undefined)
{
tt.submit();
}
}
</script>
</body>
</html>

然后,post接收页面:

<HTML>
<head>
<title>工单手工前转</title>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=gb2312"/>
<script language="JavaScript">

</script>
</head>
<BODY BGCOLOR=LIGHTGREY>
<div  id="DB">
</div>
<pre>
userName        :<% =request("userName") %>
systemName      :<% =request("systemName") %>
serSupplier     :<% =request("serSupplier") %>
serCaller       :<% =request("serCaller") %>
callTime        :<% =request("callTime") %>
alarmID         :<% =request("alarmID") %>
orialarmId      :<% =request("oriAlarmId") %>
alarmTitle      :<% =request("alarmTitle") %>
alarmCreateTime :<% =request("alarmCreateTime") %>
neType          :<% =request("neType") %>
neName          :<% =request("neName") %>
alarmLevel      :<% =request("alarmLevel") %>
alarmType       :<% =request("alarmType") %>
alarmRedefLevel :<% =request("alarmRedefLevel") %>
alarmRedefType  :<% =request("alarmRedefType") %>
alarmLocation   :<% =request("alarmLocation") %>
alarmDetail     :<% =request("alarmDetail") %>
alarmPropose    :<% =request("alarmPropose") %>
alarmRegion     :<% =request("alarmRegion") %>
</pre>

<BUTTON STYLE="WIDTH:30" ID="ButtonOK">确定</BUTTON>
<BUTTON STYLE="WIDTH:30" ID="ButtonCancel">取消</BUTTON>

</BODY>
</HTML>

webbrowser绑定:

webBrowser.DocumentText=s;

最后,在页面上,webbrowser上显示的结果,最后接收页面,中文会出现乱码.而如果把这两处代码保存为htm 和asp页面后,浏览htm页面post后asp页面不会出现乱码.

解决办法:

程序中不拼写第一个页面，改为这样的:

strTemp = string.Format(@"{0}={1}&", s, System.Web.HttpUtility.UrlEncode(strValue, System.Text.Encoding.GetEncoding("gb2312")));
strBuilder.Append(strTemp);

既弄成象url地址一样的串.但是,主要的一点，还是 System.Web.HttpUtility.UrlEncode的转换.

最后，绑定到webbrowser控件:

string headers = "Content-Type: application/x-www-form-urlencoded";
this.webBrowser.Navigate(http://localhost/test.asp, "", System.Text.Encoding.GetEncoding("gb2312").GetBytes(s), headers);

读取webBrowser的源码

不能够直接用webBrowser.DocumentText读取，这样出来的是乱码

System.IO.StreamReader streamReader = new System.IO.StreamReader(this.webBrowser.DocumentStream, System.Text.Encoding.GetEncoding("gb2312"));
string strWebBrowserDocument = streamReader.ReadToEnd();
