BCB程序的发送代码:

IdHTTP1->Request->ExtraHeaders->Values["cookie"] = cookie;

IdHTTP1->HandleRedirects = true;
IdHTTP1->Request->Referer = "http://xxxxx.com/getuser.do?id=42531288";
IdHTTP1->Request->AcceptLanguage = "zh-cn";
IdHTTP1->Request->ContentType = "application/x-www-form-urlencoded";
IdHTTP1->Request->AcceptEncoding = "gzip, deflate";
IdHTTP1->Request->UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)";
IdHTTP1->Host = "xxxxx.com";
IdHTTP1->Request->ContentLength = 58;
IdHTTP1->Request->Connection = "Keep-Alive";




AnsiString url = "http://xxxxx.com/gossip.do";

TStrings* tData=new TStringList();
TStringStream* stream=new TStringStream("");
tData->Add("curpage=");
tData->Add("from=main");
tData->Add("id=42531288");
tData->Add("cc=42531288");
tData->Add("body=1234567890");
IdHTTP1->Post(url,tData,stream);
Memo1->Text = stream->DataString;

用这些代码没有发送成功. 另外BCB中用到的cookie是我在程序中放了一个CppWebBrowser,登录后获得的cookie,用这个cookie可以Get出正确的页面.

大家看一下是什么问题

[weixing979]

如果不加 IdHTTP1->HandleRedirects = true;
代码会抛出 302 Found的异常,和HttpWatch接收的结果一样.
IdHTTP是BCB6自带的 Version8.0.25

[ly_liuyang]

Indy最好用9.0.1X以上的!
用WebAppDebugger处理,必要时修改Indy源码

[weixing979]

先转到D版来,总之C++builer和Delphi也差不多. 我用的IdHTTP是BCB6自带的 Version8.0.25

[weixing979]

问题已经解决了

上面的代码替换成这样就可以了,原来BCB6自带的indy8.0.25 竟然要这样填加数据
tData->Add("curpage=&");
tData->Add("from=main&");
tData->Add("id=42531288&");
tData->Add("cc=42531288&");
tData->Add("body=1234567890");
