Question

我正在尝试在UIPath中执行自定义asyncCodeActivity。添加了该包，传递了所有数据，但是UIPath仅在达到自定义活动时挂起，并且不会引发任何异常/或停止。我尝试使用CodeActivity和AsyncCodeActivity创建类库-我的活动应该进行多个APICall，但是我得到的结果是，当它到达我的自定义活动时，它只会停止，而不会转到下一个活动。有没有示例如何为UIPath创建异步自定义活动？当我尝试在UIpath之外进行测试时，我的类库工作正常。感谢您的帮助。
我的使用CodeActivity的类库：

public class AddInvoice : CodeActivity
 {       
    [Category("Input")]
    [RequiredArgument]
    public InArgument<string> PickupZip { get; set; }         

    [Category("Output")]
    [RequiredArgument]
    public OutArgument<String> Output { get; set; }

    public async Task<string> ApiTest(CodeActivityContext context)
    {            
        try
        { 
        var origin = await GoogleAPIWrapper.GetAddressByZip(PickupZip.Get(context));          
        string PickupAddress;
        string DeliveryAddress;
        var inv = new IList();
        if (origin.StatusId >= 0)
        {                
            invoice.PickupCity = origin.Locality;                
            invoice.PickupState = origin.AdminLevel1; 
        }
        else
        {               
            invoice.PickupCity = null;               
            invoice.PickupState = null;   
        }             
        var tkn = token.Get(context);
        var client = new HttpClient();
        HttpClientHandler handler = new HttpClientHandler();
        client = new HttpClient(handler, false);
        client.BaseAddress = new Uri("http://test.test.com/");
        client.DefaultRequestHeaders.Add("Authorization", "Bearer " + tkn);
        StringContent content = new StringContent(JsonConvert.SerializeObject(inv), Encoding.UTF8, "application/json");
        var response = await client.PostAsync("api/insert/", content);
        var resultContent = response.StatusCode;
            Output.Set(context, resultContent.ToString());
    }
        catch (Exception e)
        {                
            Output.Set(context, e.ToString());
        }
        return "ok";
}
    protected override void Execute(CodeActivityContext context)
    {
        try
        {
            string result = ApiTest(context).GetAwaiter().GetResult();
        }
        catch (Exception e)
        {
            Output.Set(context, e.ToString());
        }
    }      


    public class IList
    {            
        public string PickupState { get; set; }            
        public string PickupCity { get; set; }           
    }

}

默认情况下，从CodeActivity派生的类是同步的。由于UiPath基于Windows Workflow，因此应该可以从AsyncCodeActivity类派生。

您没有明确要求它，但是由于本质上是在调用Web服务，因此请查看Web Activities软件包，尤其是HTTP Request。这还带有JSON反序列化。例如，您可以找到有关Web服务集成here的更多信息（免责声明：我是作者）。
