I am accessing my configuration stored in Azure Appconfiguration. I am using SDK (Azure.Data.AppConfiguration) from Azure function. Following the example from https://github.com/Azure/azure-sdk-for-net/blob/Azure.Data.AppConfiguration_1.0.2/sdk/appconfiguration/Azure.Data.AppConfiguration/samples/Sample2_HelloWorldExtended.md
I am keep getting 400 error.
Following is my code
var client = new ConfigurationClient(_azureAppConfigurationOptions.ConnectionString);
ConfigurationSetting setting = client.
GetConfigurationSetting(
"appid");
the only difference is i am calling from Azure functions.
Any help or insight is appreciated.
When try to get configuration(app settings) in azure function, you should use this method Environment.GetEnvironmentVariable(xxx).
Please refer to this article for details.

I was trying to get the connection string from the azure key vault for azure functions. These are the steps I did,
Created a managed identity(System assigned) in the azure functions
Create a secret in an azure key vault
Add access policies to give permission to the azure function app
Added an entry in the app settings for connection string where the value was #Microsoft.KeyVault(SecretUri=SECRETURLOFKEYVAULT)
But when I run the azure function I am getting below error,
"Keyword not supported: #microsoft.keyvault(secreturi....."
This is how I have enabled managed identity,
And my access policy looks like below,
Any help would be much appreciated
I ran into a similar problem by following the tutorial. My remedy was a restart of the function app. Saving of the app setting was not enough for the Function App to start using the Key Vault secret provider correctly.
According to the steps you provided, it have no problem to work well. Here is the tutorial about get key vault secrets in Azure Function you could refer to.
Note: Add access policies to the azure function app with the Get permission on secrets and that was enough.
Also, here is a similar issue that get same error like you which is due to IP Address restriction blocking it.
This issue occurred while testing on local. It was resolved after doing an az login.
In Azure Portal, you can get function URL directly from portal. there is also another way here that you can get Azure Function URL using Azure ARM API. But I want to know, Is there any way to get "Function URL" by code (Node.js, Python, ...) in Azure Function Apps directly?
For Node.js azure function, you can just use this line of code: req.originalUrl.
Detailed steps as below:
1.In Azure portal, create a Http Trigger function, select JavaScript as it's Programming Language.
2.In the index.js file, add this line of code: context.log(req.originalUrl);
3.Sample code like below:
module.exports = function (context, req) {
context.log(req.originalUrl);
//write you other logic below
};
Please refer to the screenshot below for test result:
I want to call a Azure function after PostDeployment. So I have a created a HttpTriggerCsharp Azure function.
I have done the following:-
Go to Kudu console
Tools
Web hooks
Add HttpTriggerCsharp Azure
function URL with PostDeployment option.
I am using Git-hub for
deployment. I am doing push now.
HttpTriggerCsharp Azure function is
called and executed. But I see Status and Reason of the Web hook as
Bad Request. Refer
Why I am Status and Reason as "Bad Request"? What is the issue here?
I have removed the code which relates to request body ( dynamic data = await req.Content.ReadAsAsync();).
Now my code is working now.
So I'm fairly new to working with Azure and there are some things I can't quite wrap my head around. One of them being the Azure Storage Account.
My web jobs keeps stopping with the following error "Unhandled Exception: System.InvalidOperationException: The account credentials for '[account_name]' are incorrect." Understanding the error however is not the problem, at least that's what I think. The problem lies in understanding why I need an Azure Storage Account to overcome it.
Please read on as I try to take you through the steps taken thus far. Hopefuly the real question will become more clear to you.
In my efforts to deploy a WebJob on Azure we have created the following resources so far:
App Service Plan
App Service
SQL server
SQL database
I'm using the following code snippet to prevent my web job from exiting:
JobHostConfiguration config = new JobHostConfiguration();
config.DashboardConnectionString = null;
new JobHost(config).RunAndBlock();
To my understanding from other sources the Dashboard connection string is optional but the AzureWebJobsStorage connection string is required.
I tried setting the required connection string in portal using the configuration found here.
DefaultEndpointsProtocol=[http|https];AccountName=myAccountName;AccountKey=myAccountKey
Looking further I found this answer that clearly states where I would get the values needed, namely an/my missing Azure Storage Account.
So now for the actualy question: Why do I need an Azure Storage Account when I seemingly have all the resources I need place for the WebJob to run? What does it do? Is it a billing thing, cause I thought we had that defined in the App Service Plan. I've tried reading up on Azure Storage Accounts over here but I need a bit more help understanding how it relates to everything.
From the docs:
An Azure storage account provides resources for storing queue and blob data in the cloud.
It's also used by the WebJobs SDK to store logging data for the dashboard.
Refer to the getting started guide and documentation for further information
The answer to your question is "No", it is not mandatory to use Azure Storage when you are trying to setup and run a Azure web job.
If you are using JobHost or JobHostConfiguration then there is indeed a dependency for Storage accounts.
Sample code snippet is give below.
class Program
{
static void Main()
{
Functions.ExecuteTask();
}
}
public class Functions
{
[NoAutomaticTrigger]
public static void ExecuteTask()
{
// Execute your task here
}
}
The answer is no, you don't. You can have a WebJob run without being tied to an Azure Storage Account. Like Murray mentioned, your WebJob dashboard does use a storage account to log data but that's completely independent.
I've been looking around and I can't find a concise example around getting this metric. I've installed WindowsAzure.Management.Compute and now I don't know where to begin. How can this be done?
I would recommend you to take a look at Azure Resource Explorer: https://resources.azure.com. You could find the instances request URL as following:
For the Authorization header please have a look at this article. We can use C# HttpRequest to write the code. Here is the result I tested in fildder.
the endpoint:
https://management.azure.com/subscriptions/<subscription id>/resourceGroups/jatestgroup/providers/Microsoft.Web/sites/testcore1/instances?api-version=2015-08-01
Result:
We can calculate the instance number from the response json. In addition, it will need a long time in this rest API to show all instances when scale the instance in azure portal.
[Update]
According with my comment, I tested with the article:http://blog.amitapple.com/post/2014/03/access-specific-instance/#.V9tLKyh95hF
The following is my result:
Please download the library at here. Refer to this article for more information about Windows Azure Management Certificates.
Here is the code snipped:
var cert = new X509Certificate2();
cert.Import(Convert.FromBase64String(""));
var _client = new Microsoft.WindowsAzure.Management.WebSites.WebSiteManagementClient(new Microsoft.WindowsAzure.CertificateCloudCredentials("****", cert));
var ids= await _client.WebSites.GetInstanceIdsAsync("EastAsiawebspace", "testcore1");
You cannot get the instance count from within one instance of the Web App. But you can get it from the portal, or from the Azure ARM API (it's the numberOfWorkers property on the Web Hosting Plan object).
Also, note that WindowsAzure.Management.Compute does not apply to Azure Web App.
