我已成功通过Google OAuth API进行身份验证。这是它第一次正常运行。对于第二次访问相同的内容，我得到以下错误:

"发送直接消息或获取响应时发生错误。"

堆栈跟踪:

    [WebException: The remote server returned an error: (400) Bad Request.]

方法

private IAuthorizationState GetAuthorization(WebServerClient client)
{
    String accesstoken = "";
    IAuthorizationState state = AuthState;
    if (state != null)
    {
        return state;
    }
    state = client.ProcessUserAuthorization(new HttpRequestInfo(HttpContext.Current.Request));        
    if (state != null && (!string.IsNullOrEmpty(state.AccessToken) 
        || !string.IsNullOrEmpty(state.RefreshToken)))
    {
        accesstoken = state.AccessToken;
        HttpContext.Current.Session["AUTH_STATE"] = _state = state;      
        return null;
    }
    string scope = TasksService.Scopes.TasksReadonly.GetStringValue();
    OutgoingWebResponse response = client.PrepareRequestUserAuthorization(new[] { 
            scope, 
            "https://www.googleapis.com/auth/userinfo.profile", 
            "https://www.googleapis.com/auth/userinfo.email" 
        });
    response.Send();
    return null;
}
private IAuthorizationState AuthState
{
    get
    {
        return _state ?? HttpContext.Current.Session["AUTH_STATE"] as IAuthorizationState;
    }
}

行

 state = client.ProcessUserAuthorization(new HttpRequestInfo(HttpContext.Current.Request));

等待有价值的回复和评论

请检查您是否正在呼叫客户端。只ProcessUserAuthorization一次。从具有相同参数的第二次调用开始，它可以继续"发送直接消息或获得响应"错误。
