Idhttp实现HTTP Post提交
问题的由来:
我有两个asp文件
a.asp内容:
<html>
<head>
</head>
<body>
<form action="b.asp" method=post target="_self">
<P><INPUT id="Text1" type="text" name="Text1">
<INPUT id="Submit1" type="submit" value="Submit" name="Submit1"></P>
</form>
</body>
</html>
b.asp内容:
<html>
<body>
<%response.Write request.Form.Count%>
<%response.Write request.Form("text1")%>
</body>
</html>
在IE中点a.asp的提交按钮时显示2,但用Delphi 6 该如何实现呢?我用TNMHTTP的post, NMHTTP1.Post('http://localhost/test/b.asp', 'text1=ddssssddd'); 显示了Count,但text1的内容无法显示,听说TNMHTTP存在编码的问题,我又用Delphi6的Indy Http,就是Delphi自带的例子,Delphi安装目录下的Demo\Indy\HTTPClient也无法显示,不知是何原因?
回复的代码
{sHttp 是idhttp控件
netinfo是我自自定义的记录类型,用来保存用户设置的代理的信息。
}
application.ProcessMessages;
with sHttp do
begin
Disconnect;
//Request.UserAgent:='Mozilla/4.0 (compatible; MSIE 5.5; Windows 98)';
Request.UserAgent:='CSDN Helper ver1.0 Build0402';
RedirectMaximum:=0;
Request.ContentType:='application/x-www-form-urlencoded'; //这句最重要了
Request.ContentLength:=length(memo1.Text); //这个也要。
if (netinfo.flg_UseProxy=true) then
begin
Request.ProxyUsername:=netInfo.prx_User;
Request.ProxyPassword:=netInfo.prx_Pass;
Request.ProxyServer:=netInfo.prx_IP;
Request.ProxyPort:=StrToIntDef(netInfo.prx_Port,80);
end;
Rsp:=TStringStream.Create('');
try
Post(csdn.ReplyUrl,memo1.Lines,Rsp);
reStr:= Rsp.DataString;
finally
Rsp.Free;
end;
end; //end of With
