如何在Web api 2 / app见解中生成相关ID？

Question

我正在Web api 2项目中使用App Insights，该项目被称为React前端。

发生错误时，我想向用户显示一个常见错误，例如：请与管理员联系，并向他们显示Guid或错误号。

然后使用该错误号，我可以在App Insights中检查真正的异常是什么。

这可能吗？

我的网络api代码在下面

namespace LuloWebApi.Controllers
{
    [Authorize]
    public class ClientController : ApiController
    {

        [HttpGet]
        public async Task<List<Client>> GetClients()
        {
            //var telemetry = new TelemetryClient();
            //try
            //{
                var clientStore = CosmosStoreHolder.Instance.CosmosStoreClient;
                return await clientStore.Query().ToListAsync();
            //}
            //catch (System.Exception ex)
            //{
            //    telemetry.TrackException(ex);

           //}
        }

        [HttpGet]
        public async Task<IHttpActionResult> GetClient(string clientId)

如果我误会你，请纠正我。

我认为这就像手动创建一个guid一样简单，并且可以将异常遥测以及BadRequest（）添加到其中。

#!/bin/bash

set -xe

MASTER_USERNAME=$2
MASTER_PASSWORD=$3
NODE_NAME=$4
NUM_EXECUTORS=$5

# Download CLI jar from the master
curl ${MASTER_URL}/jnlpJars/jenkins-cli.jar -o ~/jenkins-cli.jar

# Create node according to parameters passed in
cat <<EOF | java -jar ~/jenkins-cli.jar -auth "${MASTER_USERNAME}:${MASTER_PASSWORD}" -s "${MASTER_URL}" create-node "${NODE_NAME}" |true

# Creating the node will fail if it already exists, so |true to suppress the

当您获得GUID时，可以在azure门户中搜索相关的错误：
