使用Kudu API将带有serviceBusTrigger的azure函数部署到现有的函数应用程序中，即使在手动同步触发器后也不会触发

Question

我有一个现有功能应用程序，在应用程序中的用户操作之后，我需要将serviceBusTrigger函数部署到该应用程序。为了做到这一点，我一直在使用下面的post Deploy Azure函数from code(C#)。

public void CreateAzureFunctionToMonitorQueue(string functionName, string serviceBusQueueName, string path)
    {
        // create zip of new function
        // ZipFile.CreateFromDirectory will create a zip with the directory's name containing the directory's contents
        // so CreateZipOfFunc creates a structure <functionName>/<functionName>/function.json
        // so that the zip contains <functionName>/function.json 
        // which is the required input for api/zip/ from kudu api
        var zipFile = CreateZipOfFunc(functionName, serviceBusQueueName, path);
        var file = File.ReadAllBytes(zipFile);

        MemoryStream stream = new MemoryStream(file);

        using (var client = new HttpClient())
        {
            // deploy zip using Kudu REST api
            client.DefaultRequestHeaders.Add("Authorization", "Basic " + _base64Auth);
            var baseUrl = new Uri($"https://{_webFunctionAppName}.scm.azurewebsites.net/");
            var requestURl = baseUrl + "api/zip/site/wwwroot";
            var httpContent = new StreamContent(stream);
            var response = client.PutAsync(requestURl, httpContent).Result;
        }
        // remove files
        Directory.Delete($"{path}{functionName}", true);
        File.Delete($"{path}{functionName}.zip");
        // deployment using Kudu REST api requires the function triggers to be manually synced
        SyncTriggers();
    }

public void SyncTriggers()
    {
        using (var client = new HttpClient())
        {
            var requestUrl = $"https://{_webFunctionAppName}.azurewebsites.net/admin/host/synctriggers?code={_MASTER_KEY}";
            var httpContent = new StringContent("");
            var response = client.PostAsync(requestUrl, httpContent).Result;
        }
    }

如果我启用已经存在的使用VS部署的函数，该函数将激发并处理消息。

现有函数的function.json文件如下所示

{
  "generatedBy": "Microsoft.NET.Sdk.Functions-1.0.26",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "serviceBusTrigger",
      "connection": "ServiceBusConnection",
      "queueName": "myqueue",
      "name": "queueItem"
    }
  ],
  "disabled": false,
  "scriptFile": "../bin/MyProject.MyLibrary.dll",
  "entryPoint": "MyProject.MyLibrary.MyClass.RunAsync"
}

使用上述方法部署的函数具有如下所示的function.json

{
  "generatedBy": "Microsoft.NET.Sdk.Functions - 1.0.26",
  "configurationSource": "attributes",
  "bindings": [
    {
      "type": "serviceBusTrigger",
      "connection": "ServiceBusConnection",
      "queueName": "myqueue",
      "name": "queueItem"
    }
  ],
  "disabled": false,
  "scriptFile": "../bin/MyProject.MyLibrary.dll",
  "entryPoint": "MyProject.MyLibrary.MyClass.RunAsync"
}

Your endpoint must trigger/bind to only one Azure Function

编辑2：这似乎只是与az fns绑定资源有关，似乎没有帮助

Edit3:经过大量研究，看来我生成的function.json的configurationSource不应该是“attributes”，而应该是“config”。现在要测试这个。

Edit4:通过删除generatedBy并将我正在生成的function.json文件中的configurationSource更改为“config”，解决了这个问题。

问题是使用VS部署的函数在function.json中具有这两个属性

"generatedBy": "Microsoft.NET.Sdk.Functions - 1.0.26",
"configurationSource": "attributes",

这实际上只是告诉azure函数是从哪里生成的,并使用函数入口点方法的属性作为配置源。删除generatedBy允许编辑azure portal中的函数，并将configurationSource更改为“config”，告诉azure函数运行时使用function.json文件进行绑定配置。

但是，在azure门户中，我收到了一条消息

Error:

Function (MyFunction) Error: Configuration error: all functions in D:\home\site\wwwroot\bin\MyProject.MyLibrary.dll must have the same value for 'configurationSource'.
Session Id: MY_SESSION_ID

Timestamp: 2019-06-30T21:04:22.709Z

因此将output function.json更改为

{
  "configurationSource": "config",
  "bindings": [
    {
      "type": "serviceBusTrigger",
      "connection": "ServiceBusConnection",
      "queueName": "myqueue",
      "name": "queueItem"
    }
  ],
  "disabled": false,
  "scriptFile": "../bin/MyProject.MyLibrary.dll",
  "entryPoint": "MyProject.MyLibrary.MyClass.RunAsync"
}

解决了我的问题
