来自样板中应用程序级别的PostAsync调用

Question

更新：核心问题是ABPSesssion在postasync请求之后为空。我认为，如果我能找回我的抱负，它将奏效。

我正在尝试对postAsync类型进行api调用。问题是，当我尝试使用createAsync将响应保存到数据库中时，我得到的响应非常好，我得到对象实例的异常。我检查了所有日志，上面写着“策略执行失败。请求来源http://localhost:21021没有访问资源的权限。”

对于getasync api调用，同一件事工作得很好。我该怎么办，我是从拥有所有权限的管理员帐户登录的]

//代码

    HttpClient client = new HttpClient();
    var SLACK_TOKEN = OneConsts.SlackToken;

    var values = new Dictionary<string, string>
    {
        { "token", SLACK_TOKEN },
        { "name", "contacts2" },
    };

    var content = new FormUrlEncodedContent(values);
    var response = await client.PostAsync("https://slack.com/api/conversations.create", content);

    var data = response.Content.ReadAsStringAsync().Result;
    JObject obj = JObject.Parse(data);

    foreach (var item in obj["channel"])
    {
        input.ChannelId = obj["channel"]["id"].ToString();
        input.ChannelName = obj["channel"]["name"].ToString();
        input.JSONinfo = obj["channel"].ToString();
        var slack = SlackConnector.Create(input.ChannelId, input.ChannelName, input.JSONinfo);
        await _slackconnectorManager.CreateAsync(slack);
        CurrentUnitOfWork.SaveChanges();
        MapToEntityDto(slack);
例外：

问题很简单，我需要用postasync替换该行var response = client.PostAsync（“ https://slack.com/api/conversations.create”，content）.Result;
