问调用TIMLogin之后没有成功或失败的回调？

使用mingw编译，按顺序调用相关函数后，没有登录成功或失败的回调。

static void callback(int32_t code, const char* desc, const char* json_params, const void* user_data) //这个回调函数一直没有被调用

{

if (code != ERR_SUCC) { // 登入失败

printf("Failure!code:%d desc", code, desc);

return;

}

printf( "Success!");

}

int main()

{

WSADATA WSAData;

if( WSAStartup( MAKEWORD( 1, 1 ), &WSAData ) )

{

WSACleanup( );

printf("WSAStartup Fail");

return 0;

}

std::string version = TIMGetSDKVersion();

printf("%s\n",version.c_str());

json_value_init[kTIMSdkConfigLogFilePath] = "D:\\IMData\\";

json_value_init[kTIMSdkConfigConfigFilePath] = "D:\\IMData\\";

printf("%s\n",json_value_init.toStyledString().c_str());

if (TIM_SUCC != TIMInit(sdk_app_id, json_value_init.toStyledString().c_str())) {

printf("TIMInit Fail!\n");

return 0;

}

std::string sig = genTestUserSig(user);

//std::string sig = "eAGrVgrxCdYrSy1SslIy0jNQ0gHzM1NS80oy0zLBwoZgAJUpTslOLCjITFGyMjQxMDAxN7E0MoDoSa0oyCxKVbIyMzCxMICKlWTmAkUMzSBGWJhAVBZnpgNty3BO8TLKispzD3fNKYs01df3cgwrLvUJTCsqD-PKyC6p0HcrtAw1CysNTbdVqgUAbUAwag__";

printf("sig:%s!\n",sig.c_str());

if(TIM_SUCC != TIMLogin(user, sig.c_str(), callback, user))

{

printf("TIMLogin Fail!\n");

return 0;

}

while(1)

{

usleep(1000);

}

return 0;

}
