Azure WebJobs SDK ServiceBus连接字符串'AzureWebJobsAzureSBConnection'丢失或为空 [英] Azure WebJobs SDK ServiceBus connection string 'AzureWebJobsAzureSBConnection' is missing or empty

问题描述

我在Visual Studio 2015中创建了一个Azure Function应用程序.该应用程序具有服务总线队列的触发器.当我在本地运行该应用程序时，它运行完美.它能够从Service Bus队列中读取数据(通过名为AzureSBConnection的变量配置)并将其记录在我的数据库中.

I created an Azure Function App in Visual Studio 2015. The App has a trigger for service bus queues. The app works perfectly when I run it locally. It is able to read the data from the Service Bus queue (configured via a variable named AzureSBConnection) and log it in my database.

但是在Azure中部署它会给我以下错误:

But it gives me the following error when deployed in Azure:

函数($ ServiceBusQueueTriggerFunction)错误:Microsoft.Azure.WebJobs.Host:错误索引方法"Functions.ServiceBusQueueTriggerFunction". Microsoft.Azure.WebJobs.ServiceBus:Microsoft Azure WebJobs SDK ServiceBus连接字符串'AzureWebJobsAzureSBConnection'丢失或为空.

Function ($ServiceBusQueueTriggerFunction) Error: Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.ServiceBusQueueTriggerFunction'. Microsoft.Azure.WebJobs.ServiceBus: Microsoft Azure WebJobs SDK ServiceBus connection string 'AzureWebJobsAzureSBConnection' is missing or empty.

请注意，我的连接称为AzureSBConnection，而不是AzureWebJobsAzureSBConnection.同样，该连接在本地工作.最后，部署的文件看起来与本地文件完全一样.

Note that my connection is called AzureSBConnection and not AzureWebJobsAzureSBConnection. Also, the connection works locally. And finally, the deployed file looks exactly like the local file.

Visual Studio结构如下:

The Visual Studio structure looks like the following:

function.json文件具有一系列设置，如下所示:

The function.json file has a bunch of settings as shown below:

然后在Appsettings.json文件中，我具有以下内容:

Then in the Appsettings.json file, I have the following:

为了进行部署，我将文件通过FTP传输到Azure中的功能应用程序的D:\ home \ site \ wwwroot位置. Kudu中的最终结构如下:

For deploying, I FTPed the files to the D:\home\site\wwwroot location for my Function App in Azure. The final structure in Kudu looks like:

如果我进入函数文件夹，

And if I go inside my function folder:

这是部署的function.json:

Here is the deployed function.json:

这是部署的应用程序设置:

And here is the deployed appsettings:

部署的json文件与本地文件完全相同.但是由于缺少AzureWebJobsAzureSBConnection，因此部署的版本出错了.我究竟做错了什么?

The deployed json files are exactly the same as the local files. But the deployed version is erroring out because of the missing AzureWebJobsAzureSBConnection. What am I doing wrong?

推荐答案

应用设置和连接字符串仅支持环境变量.

Only environment variables are supported for app settings and connection strings.

您需要确保在门户网站的功能"应用程序设置中设置了环境变量AzureWebJobsAzureSBConnection:

You need to make sure that the environment variable AzureWebJobsAzureSBConnection is set on your Function's app settings in the portal:

，然后在其中添加具有正确连接字符串的AzureWebJobsAzureSBConnection变量:

and then once there, you need to add the AzureWebJobsAzureSBConnection variable with the proper connection string:

，然后您可以通过以下方式通过代码进行访问:

and then you can access this via code by:

Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);

这将从appsettings.json或环境变量中获取值，具体取决于函数从何处执行(本地调试或在Azure上部署)

This will obtain the value from either the appsettings.json or the environment variable depending on where the function is being executed from, (local debugging or deployed on Azure)
