从Azure Functions连接到WCF服务并对程序集绑定进行故障排除 [英] Connecting to WCF service from Azure Functions and trouble-shooting assembly bindings

问题描述

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

Where can I see the Assembly that Azure functions is trying to load ? (Like fuslogvw on windows)

更新根据要求更新标题，以更好地反映接受的答案

更新

将我的代码更改为使用WebClient'手动'构造SOAP请求，并且它可以正常工作...因此，我认为WCF服务代理在Azure功能的沙箱中无法正常运行...不过，我仍然希望关于如何查看程序集绑定日志视图的答案.

Changed my code to 'manually' construct the SOAP request using WebClient and it works ... so me thinks somewhere the WCF service proxy is not playing well within the sandbox that is Azure Functions ... Nevertheless I would still like an answer as to how we can see the Assembly binding log views.

我一直遇到相同的错误:

I keep getting the same error :

推荐答案

当前，不支持查看程序集绑定日志.启用诊断日志将有助于调试大多数错误.还可以查看记录提示和技巧.

Currently, there is no support to view assembly binding logs. Enabling diagnostic logs will help debug most of the errors. Also take a look at logging tips and tricks.

以下是从您的函数连接到Azure托管的WCF服务的示例:

Here is a sample for connecting to a WCF service hosted in Azure from your function:

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

4. 上载WCF服务合同IService1.csx.您可以从Kudu或在门户网站上查看文件来完成此操作

1. Got to Function App Settings --> Go to Kudu --> Go to D:\home\site\wwwroot\YourFunction
2. Create folder bin
3. Upload System.ServiceModel.dll

4. Upload WCF service contract IService1.csx. You can do this from either Kudu or View Files on the portal

 #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:

Sample queue trigger that invokes WCF endpoint:

#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}");
 }
