c# - Dynamics C# 插件在运行时失败，但在调试时成功

标签 c# plugins dynamics-crm microsoft-dynamics microsoft-dynamics-webapi

概览

我在本地使用 Dynamics 2016。

我在 Microsoft Dynamics 中有一个业务流程来处理新客户端的创建。该过程完成后，我将附加一个工作流，该工作流启动一个调用插件进行一些自定义处理的操作。我正在关注 this文章来设置这个过程。当此插件在 Dynamics 中被触发时，它似乎运行成功，但没有创建我期望它创建的记录。但是，当我分析插件并通过插件注册工具/Visual Studio 运行它时，会创建我希望看到的记录。

当我将跟踪日志添加到我的插件时，我注意到当我调用 Web API 时似乎收到了来自 Dynamics 的 401 - Unauthorized 错误。当我在调试时查看网络流量时，我似乎收到了初始 401 错误，但随后重试成功获取了我试图获取的记录。

代码

这是我认为 401-Unauthorized 错误的代码部分

private void GetGlobalFieldNameMapsAsync(String url = "ccseq_globalfieldnamemaps?$select=ccseq_system,ccseq_entitytype,ccseq_fieldtype,ccseq_name,ccseq_datatype")
{
    HttpClient client = new HttpClient(new HttpClientHandler() { Credentials = new NetworkCredential("admin", "password", "domain") });
    HttpResponseMessage responseMessage = new HttpResponseMessage();
    try
    {
        client.BaseAddress = new Uri(Helpers.GetSystemUrl(APIConnector.Application.Dynamics));
        client.DefaultRequestHeaders.Clear();
        client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Add("OData-MaxVersion", "4.0");
        client.DefaultRequestHeaders.Add("OData-Version", "4.0");    

        responseMessage = client.GetAsync(url).Result;    

        JObject responseData = JObject.Parse(responseMessage.Content.ReadAsStringAsync().Result);

        if (responseData["@odata.nextLink"] != null)
        {
                    GetGlobalFieldNameMapsAsync(Convert.ToString(responseData["@odata.nextLink"]));
        }

        foreach (var v in responseData["value"])
        {
            GlobalFieldNameMap newGFNM = new GlobalFieldNameMap();
            newGFNM.System.Value = Convert.ToInt32(v["ccseq_system"]);
            newGFNM.EntityType.Value = Convert.ToInt32(v["ccseq_entitytype"]);
            newGFNM.FieldType.Value = Convert.ToInt32(v["ccseq_fieldtype"]);
            newGFNM.FieldName.Value = Convert.ToString(v["ccseq_name"]);
            newGFNM.DataType.Value = Convert.ToInt32(v["ccseq_datatype"]);
            FieldNameMap.Add(newGFNM);
        }

    }
    catch (Exception e)
    {
        throw new Exception(e.Message + " - " + responseMessage.Content.ReadAsStringAsync().Result);
    }
}

网络流量

Network Traffic

我似乎无法理解为什么我在调试期间看到插件成功运行，但在动态中直接运行时却看到它失败。该插件似乎在同一用户下运行，无论它是在 Dynamics 中运行还是在我的本地计算机上运行。我正在传递管理员凭据，因此他们应该拥有在系统中执行任何操作的完全权限。有什么想法吗？

我问过this问题和this可能相关的问题，但没有完全涵盖这个问题。

更新

我在跟踪日志中注意到这条错误消息

最佳答案

我认为这里的答案是不要在插件中使用 Web API。

Use Dynamics 365 web services

Web API

Use the Web API for any projects that access Dynamics 365 data with code that doesn’t run on the server, including requests from web resources and form scripts that run in Dynamics 365 application clients. At this time you can’t easily use the Web API for code that runs on the server, such as in plug-ins or workflow assemblies.

Organization service

Business logic that runs in plug-ins or workflow assemblies on the server expect to use the Organization service.

至于为什么您的插件跟踪日志中出现 401 - Unauthorized。我怀疑这可能是因为您正在尝试让 CRM 自行调用，而它根本无法进行身份验证。无论如何插件Web Access在这方面非常有限。

The following web access restrictions apply to this sandbox capability.

  • Anonymous authentication is supported and recommended.

关于为什么插件在调试时起作用，我猜是因为 HTTP 请求现在是从您的本地计算机而不是服务器发送的。我假设 Fiddler 日志来自您的机器。

最后，调试的时候最开始的401后面跟着success；我相信 401 是一个凭证挑战，它是 common在许多身份验证方案中。
