从 Azure Functions 和 trouble-shooting 程序集绑定连接到 WCF 服务

Question

在哪里可以看到 Azure 函数试图加载的程序集？（喜欢 windows 上的 fuslogvw）

更新根据要求更新标题以更好地反映已接受的答案

更新

将我的代码更改为 'manually' 使用 WebClient 构造 SOAP 请求并且它有效......所以我认为 WCF 服务代理在 Azure Functions 沙箱中的某个地方不能正常运行......不过我仍然希望得到关于如何查看程序集绑定日志视图的答案。

我不断收到同样的错误：

目前不支持查看程序集绑定日志。 Enabling diagnostic logs will help debug most of the errors. Also take a look at logging tips and tricks.

这是一个从您的函数连接到 Azure 中托管的 WCF 服务的示例：

进入功能应用程序设置 --> 转到 Kudu --> 转到 D:\home\site\wwwroot\YourFunction
创建文件夹bin
上传System.ServiceModel.dll

上传 WCF 服务合同 IService1.csx。您可以从门户网站上的 Kudu 或查看文件执行此操作

 #r "System.ServiceModel.dll"

 using System.ServiceModel;

 [ServiceContract]
 public interface IService1
 {
     [OperationContract]
     string GetData(int value);

     [OperationContract]
     string WelComeMessage(String name);
 }

调用 WCF 端点的示例队列触发器：

#r "System.ServiceModel.dll"
#load "IService1.csx"

using System;
using System.ServiceModel;

public static void Run(string myQueueItem, TraceWriter log)
{
    log.Info($"C# Queue trigger function processed: {myQueueItem}");

    BasicHttpBinding b = new BasicHttpBinding();
    EndpointAddress ea = new  EndpointAddress("http://YourServiceAddress/service1.svc?wsdl");
    var myChannelFactory = new ChannelFactory<IService1>(b, ea);
    IService1 client = myChannelFactory.CreateChannel();
    var msg= client.WelComeMessage("HelloWorld");
    ((ICommunicationObject)client).Close();
    log.Info($"Hello from WCF: {msg}");
 }

希望对您有所帮助！
