如何检索http正文？

Question

我的代码有问题。当我在C＃服务器中向C ++客户端发送响应时，我最终得到了奇怪的响应。

注意：DownloadData方法仅从服务器接收数据，而没有其他内容。

C＃响应句柄：

void HandleHttpRequest(object client)
{
    HttpListenerContext cc = (HttpListenerContext)client;
    cc.Response.Headers.Add("Test: Foo");
    cc.Response.OutputStream.Write(Encoding.Default.GetBytes("Foo"), 0, Encoding.Default.GetBytes("Foo").Length);
    cc.Response.Close();
}

C ++客户端

void DoHttpRead()
{
    char* downloadedHttpBodyAndHeaders = DownloadData("127.0.0.1:49578");
    cout << string(downloadedHttpBodyAndHeaders) << endl;
}

DownloadData函数

char* DownloadData(string url)
{
    WSADATA wsaData;
    int iResult;
    iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
    if (iResult != 0) {

return "error";
    }

    struct addrinfo *result = NULL,
        *ptr = NULL,
        hints;

    ZeroMemory(&hints, sizeof(hints));
    hints.ai_family = AF_INET;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;
    iResult = getaddrinfo("127.0.0.1", "49578", &hints, &result);
    if (iResult != 0) {
        WSACleanup();
        return "error";
    }

    SOCKET ConnectSocket = INVALID_SOCKET;
    ptr = result;
    ConnectSocket = socket(ptr->ai_family, ptr->ai_socktype,
        ptr->ai_protocol);

    if (ConnectSocket == INVALID_SOCKET) {
        freeaddrinfo(result);
        WSACleanup();
return "error";
    }
    iResult = connect(ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen);
    if (iResult == SOCKET_ERROR) {
        closesocket(ConnectSocket);
        ConnectSocket = INVALID_SOCKET;
    }
    freeaddrinfo(result);

    if (ConnectSocket == INVALID_SOCKET) {
        WSACleanup();
        return "error";
    }

    int recvbuflen = 10000000;
    char* recvbuf = new char[recvbuflen];
    char sendbuffer[] = "GET / HTTP/1.1\r\nContent-Type: application/x-www-form-urlencoded\r\nHost: 127.0.0.1\r\nContent-Length: 1\r\n\r\n ";
    iResult = send(ConnectSocket, sendbuffer, sizeof(sendbuffer), 0);
    if (iResult == SOCKET_ERROR) {
        closesocket(ConnectSocket);
        WSACleanup();
        return response;
    }
    iResult = shutdown(ConnectSocket, SD_SEND);
    if (iResult == SOCKET_ERROR) {
        closesocket(ConnectSocket);
        WSACleanup();
        return "error";
    }
    char* received = new char[512];
    int totalBytesRead = 0;
    {
        do {
            iResult = recv(ConnectSocket, recvbuf, recvbuflen, 0);
            if (iResult > 0) {


                if (iResult <= 0)
                    break;

                received = (char*)realloc(recvbuf, iResult + totalBytesRead);

                memcpy(received + totalBytesRead, recvbuf, iResult);
                totalBytesRead += iResult;
            }
            else {
                break;
            }
        } while (iResult > 0);
    }
    closesocket(ConnectSocket);
    WSACleanup();
    char* received2 = new char[totalBytesRead];
    memcpy(received2, received, totalBytesRead);
    delete[] received;
    return received2;
}

C ++客户端Http主体被弄乱了。不仅是“ Foo”，它还显示为

//headers

e

Foo
8

如何在http正文中仅获取Foo文本？
