Question

500分求实例代码可为一文件添加一个http头，向一URL发送此文件请求，同时可以接收回送回来的响应文件（高分回报）

Answer 1

也给我一个
[email protected]
谢谢

Answer 2

[email protected]
偶也很渴望，先谢谢了！

Answer 3

我也要谢谢拉

Answer 4

To maofeiqiao():给你发过去了，希望对你有用

Answer 5

你是要把一个文件通过http上传, 还是仅仅接受一个http文件(响应)?

Answer 6

也给俺一个吧，也可以给分的[email protected]

Answer 7

我是将一个XML格式的文件加上一个http的头构成一个请求文件，向一URL发送此请求，些URL
将返回我一个响应文件（此文件也是XML格式加上一个HTTP头），我接收此响应文件后，要将
此头去掉，只要XML格式的文件内容

Answer 8

姑且不考虑你要传送的是什么格式的文件（其实什么格式都是一样的），在发送时只是在这个文件前加一个头，所以你看一下我给你发的browser，里面是使用字符串来处理向文件加HTTP头的

我一份，谢谢啊:)

Answer 10

客户端向服务器端发出一个 POST，内容为一段xml
服务器端收到后返回正文为xml

Answer 11

这个不难, 但是为什么这样做? 觉得有点别扭.不用你去包装, (难道你想用socket来做?). 直接用mfc的WinInet去做.到这儿去看看吧. 应该有你要的.

Answer 13

to  lengnuan(冷暖):
因我和服务器那方规定我必须这样做　我想从那里得到我想要的服务必须得按照他的协议和规定

Answer 14

CInternetSession MySession;
CHttpConnection* pServer = NULL;
CHttpFile* pFile = NULL;
LPCSTR pServerName="211.139.140.151";
INTERNET_PORT nPort=10034;
LPCSTR pstrObjectName="req.xml";
LPCSTR pstrRefer="G:/mfq/myproject/write/PosSystem/";
CString str="POST/newRequest HTTP/1.0";
str+="\r\n";
str+="Content_Type:text/xml";
str+="\r\n";
str+="Content_Length:186";
LPCSTR pstrHeaders=str+"\r\n";

try
{
pServer=MySession.GetHttpConnection(pServerName,nPort);
pFile=pServer->OpenRequest(1,pstrObjectName,pstrRefer,1,NULL,NULL,INTERNET_FLAG_EXISTING_CONNECT); pFile->AddRequestHeaders(pstrHeaders,HTTP_ADDREQ_FLAG_REPLACE);
//??????????
pFile->SendRequest();
DWORD dwRet;
pFile->QueryInfoStatusCode(dwRet);

if( dwRet>=400 && dwRet<=499 )
{ 
AfxMessageBox(_T("出现请求错误"),MB_ICONEXCLAMATION);
return;
}
else if( dwRet>=500 &&dwRet<=599 )
{
AfxMessageBox(_T("服务器错误"),MB_ICONEXCLAMATION);
return;
} CString *Buf=NULL;

pFile->Read(Buf,pFile->GetLength());


pFile->Close();
pServer->Close();
}
catch (CInternetException* pEx)
{
TCHAR szErr[1024];
pEx->GetErrorMessage(szErr, 1024);
MessageBox(szErr,_T("错误"));
pEx->Delete();
}
if (pFile != NULL)
delete pFile;
if (pServer != NULL)
delete pServer;
MySession.Close();
为什么出现请求错误提示，我在调试中在//??????????标记处添加代码读出pFile的内容为空？

Answer 15

对于服务器的请求，很简单：GET或者POST
如果是POST文件，需要定义数据类型服务器响应头标结构如下，在结构后面发送数据就可以了：
sprintf(buf,"HTTP/1.0 %s\r\nContent-Length: %d\r\nContent-Type: %s\r\nDate: %s\r\nServer: %s\r\n\r\n",szStatusCode,iSize, szDataType,szDT, SERVERNAME);常用nContent-Type如下：

谢谢你
这也是个实现的方法，我看过你所给网页里面的那个DEMO
觉得这样实现有些复杂
