Azure函数自定义ILogger

Question

希望一些比我更了解Azure功能的人能提供帮助。

开箱即用，您可以使用应用程序设置中的APPINSIGHTS_INSTRUMENTATIONKEY设置登录到应用程序Insights...这将在基本级别记录函数请求，然后允许您执行log.loginformation等操作。

这只是被跟踪器或ilogger所掩盖。

Answer 1

问题是，我不想将密钥存储在我的配置中，我想将它与应用程序的所有其他密钥一起存储在KeyVault中。

我们可以将APPINSIGHTS_INSTRUMENTATIONKEY存储在密钥库中。我推荐您可以使用Azure MSI函数。

我还为它做了一个演示。下面是我的详细步骤。

3.使用复制的INSTRUMENTATIONKEY vaule创建机密。

4.如果要从Azure应用程序中获取秘密，需要添加访问策略

5.用VS创建一个httptrigger函数，并添加下面的演示代码。

 public static async Task<TelemetryClient> GeTelemetryClient()
        {
            var azureServiceTokenProvider = new AzureServiceTokenProvider();

            var keyVaultClient =
                new KeyVaultClient(
                    new KeyVaultClient.AuthenticationCallback(azureServiceTokenProvider.KeyVaultTokenCallback));

            var secret = await keyVaultClient.GetSecretAsync("https://{keyvault}.vault.azure.net/secrets/{sceret}")
                .ConfigureAwait(false);
            return new TelemetryClient {InstrumentationKey = secret.Value};
        }

        // This correllates all telemetry with the current Function invocation
        private static void UpdateTelemetryContext(TelemetryContext context, ExecutionContext functionContext,
            string userName)
        {
            context.Operation.Id = functionContext.InvocationId.ToString();
            context.Operation.ParentId = functionContext.InvocationId.ToString();
            context.Operation.Name = functionContext.FunctionName;
            context.User.Id = userName;
        }

        [FunctionName("Function1")]

        public static async Task<HttpResponseMessage> Run(
            [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequestMessage req,
            ExecutionContext context, ILogger log)
        {
            log.LogInformation("C# HTTP trigger function processed a request.");
            DateTime start = DateTime.UtcNow;

            // parse query parameter
            string name = req.GetQueryNameValuePairs()
                .FirstOrDefault(q => string.Compare(q.Key, "name", true) == 0)
                .Value;

            // Get request body
            dynamic data = await req.Content.ReadAsAsync<object>();

            // Set name to query string or body data
            name = name ?? data?.name;

            // Track an Event
            var telemetryClient = await GeTelemetryClient().ConfigureAwait(false);
            var evt = new EventTelemetry("Function called");
            UpdateTelemetryContext(evt.Context, context, name);

            telemetryClient.TrackEvent(evt);

            // Track a Metric
            var metric = new MetricTelemetry("Test Metric", DateTime.Now.Millisecond);
            UpdateTelemetryContext(metric.Context, context, name);
            telemetryClient.TrackMetric(metric);

            // Track a Dependency
            var dependency = new DependencyTelemetry
            {
                Name = "GET api/planets/1/",
                Target = "swapi.co",
                Data = "https://swapi.co/api/planets/1/",
                Timestamp = start,
                Duration = DateTime.UtcNow - start,
                Success = true
            };
            UpdateTelemetryContext(dependency.Context, context, name);
            telemetryClient.TrackDependency(dependency);

            return name == null
                ? req.CreateResponse(HttpStatusCode.BadRequest,
                    "Please pass a name on the query string or in the request body")
                : req.CreateResponse(HttpStatusCode.OK, "Hello " + name);
        }
    }
}
