Update Application Settings: Azure Functions

问题

I am trying to update only one application setting using below request. My setting is getting updated properly, but my all other application settings are vanished. I see only one settings there with the correct updated value which I tried to update. I do not want to loose or change all other application settings.

What am I missing here or what is wrong I am doing?

I am following the below given article:

https://docs.microsoft.com/en-us/rest/api/appservice/webapps/updateapplicationsettings

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Web/sites/{name}/config/appsettings

I am using their online tool to send the request: https://docs.microsoft.com/en-us/rest/api/appservice/webapps/updateapplicationsettings

Since I am using the online tool it is generating the authorization token. But I want to do programmatically. It would be great if I can get the sample code to generate the token and to update application settings.

Authorization: Bearer

I reproduce your problem and if you want to update application setting, you need to write down all the application settings, otherwise it will be overridden by the one application setting.

Preparation:

1.Register an App registration in Azure Active Directory and get appid and appsecret. Please refer to this article.

2.Add the registered app into Role assignments under Access control.

Here is C# code sample you could refer to.

var appId = "xxxxxxxxxxxxxxxxxxxx";
var secretKey = "xxxxxxxxxxxxxxxxxxxx";
var tenantId = "xxxxxxxxxxxxxxxxxxx";
var context = new AuthenticationContext("https://login.windows.net/" + tenantId);
ClientCredential clientCredential = new ClientCredential(appId, secretKey);
var tokenResponse = context.AcquireTokenAsync("https://management.azure.com/", clientCredential).Result;
var accessToken = tokenResponse.AccessToken;
using (var client = new HttpClient())
{
    client.DefaultRequestHeaders.Add("Authorization", "Bearer " + accessToken);
    var baseUrl = new Uri($"https://management.azure.com/");
    var requestURl = baseUrl +
                    @"subscriptions/xxxxxxxxxxxxxxxxxxx/resourceGroups/xxxxxx/providers/Microsoft.Web/sites/xxxxxx/config/appsettings?api-version=2016-08-01";
    string body = "{\"kind\": \"webapp\",\"properties\": {\"WEBSITE_NODE_DEFAULT_VERSION\": \"6.9.1\",\"aaa\": \"bbb\"}}";
    var stringContent = new StringContent(body, Encoding.UTF8, "application/json");
    var response = client.PutAsync(requestURl, stringContent).Result;
}

The result is as below:
