CString m_StrChttpValue = _T("http://192.168.2.126:8080/ibody_op/rest/iUser/modifyUserInfo"); //personalmsg.Format(_T("{\"email\":\"%s\",\"password\":\"%s\",\"birthday\":\"%s\",\"weight\":\"%s\",\"height\":\"%s\"}"),m_User1.email,m_User1.nickname,m_User1.birthday,m_User1.weight,m_User1.height); char *charRegistered = new char[m_StrChttpValue.GetLength()]; WideCharToMultiByte(CP_ACP,0,personalmsg.GetBuffer(),strlen(charRegistered),charRegistered,personalmsg.GetLength(),NULL,FALSE); charRegistered[personalmsg.GetLength()] = '\0'; delete [] charRegistered;

恩，你是要Unicode转ANSI吧? m_StrChttpValue.GetLength()的长度是UNICODE长度，如果转ANSI那么应该是x2的。你长度不对造成的崩溃

编码转换有更简单的方式:
1. USES_CONVERSION;
wchar* pUncd = L"asdasd";
char* pAnsi = W2A(pUncd);
char* pAnsi = "asdasd";
wchar* pUncd = A2W(pAnsi);
2. CStringW struncd = L"asdasd";
CstringA strAnsi = CStringA(struncd);
