HTTP 패키지가 전송되지 않습니다.

Question

저는 Mac OS X Mavericks 용 응용 프로그램을 작성합니다. POST 및 GET 요청을 서버에 보낼 수있는 응용 프로그램이어야합니다. 우선, POST 요청을 보내려고합니다. 그러나 불행히도, 그것은 작동하지 않으며 나는 왜 모른다. 스니퍼 WireShark로 패키지를 잡으려고 할 때 패키지가 발송되지 않았 음을 보여줍니다. 이것은 내 코드입니다.

UInt32 Login(wchar_t* wstrIpAddress) 
{ 
    size_t size = wstrIpAddress.length(); 

    //create request body 
    CFStringRef bodyString = CFSTR("");

     cout << "CFStringCreateExternalRepresentation() could not convert the characters to the specified encoding. " 
     "Error code: "

답변을 찾았습니다.

1. 서버에 주소, 예를 들어, 같은 형식이어야합니다 : http://10.0.0.25하지만 만 같이하지 않는 IP -> 10.0.0.25.

2. 올바른 응답을 보장하는 응답의 상태 코드도 확인해야합니다.

   UInt32 myErrCode = CFHTTPMessageGetResponseStatusCode(myReadStream); 
   if(myErrCode != 200) 
   { 
       cout << "Request faild\n" << endl; 
       return 1; 
   }
