当我通过 C# 控制台运行 Azure CLI cmd 时，遇到错误：“错误：筛选器参数值必须是 JSON 转义字符串。”

Question

尝试通过 C# 控制台应用程序运行 Azure CLI 命令时，会遇到错误，指出：“错误：筛选器参数值必须是 JSON 转义字符串。” 下面是 C# 控制台代码：

using System;
using System.Diagnostics;
using System.IO;
using System.Text.Json;
using System.Collections.Generic;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

public class AzureCliCommandRunner
{
    public static string RunAzureCliCommand(string command)
    {
        var processStartInfo = new ProcessStartInfo
        {
            FileName = "C:\\Program Files\\Microsoft SDKs\\Azure\\CLI2\\wbin\\az.cmd",
            Arguments = command,
            RedirectStandardOutput = true,
            RedirectStandardError = true,
            UseShellExecute = false,
            CreateNoWindow = true
        };

        using (var process = new Process { StartInfo = processStartInfo })
        {
            process.Start();

            // Read the output and error streams
            string output = process.StandardOutput.ReadToEnd();
            string error = process.StandardError.ReadToEnd();

            process.WaitForExit();

            if (process.ExitCode == 0)
            {
                return output;
            }
            else
            {
                // Handle the error
                throw new InvalidOperationException($"Command execution failed. Error: {error}");
            }
        }
    }
    public static void UpdateAppConfigFilter(string endpoint, string featureName)
    {
        // Run Azure CLI commands to update AppConfig filter
        string command1 = $"appconfig feature filter show --connection-string {endpoint} --feature {featureName} --filter-name Microsoft.Targeting";
        string jsondata = RunAzureCliCommand(command1);
        JArray jsonArray = JArray.Parse(jsondata);

        JObject audience = (JObject)jsonArray[0]["parameters"]["Audience"];
        var name = "User5";
        // Add a new user to the "Users" array
        ((JArray)audience["Users"]).Add(name);

        // Convert the modified JArray back to a JSON string
        string modifiedJson = jsonArray.ToString();

        JArray jsonArray1 = JArray.Parse(modifiedJson);
        JObject firstObject = (JObject)jsonArray1.First;

        // Access the "Audience" part
        JObject audienceObject = (JObject)firstObject["parameters"]["Audience"];


        string audienceJsonString = JsonConvert.SerializeObject(audienceObject);

        //string command4 = $"appconfig feature filter update --connection-string '{endpoint}' --feature {featureName} --filter-name Microsoft.Targeting --filter-parameters 'Audience={audienceJsonString}' --yes";
        string command4 = $"appconfig feature filter update --connection-string '{endpoint}' --feature {featureName} --filter-name Microsoft.Targeting --filter-parameters 'Audience={audienceJsonString}' --yes";
        RunAzureCliCommand(command4);
    }
    public static void Main()
    {
        // Replace <<EndPoint>> and <<FeatureName>> with your actual values
        string endpoint = "<<ConnectionString here>>";
        string featureName = "featureA";

        UpdateAppConfigFilter(endpoint, featureName);
    }
}

我在上面的代码中遇到错误。

注意：从 QuickWatch 复制

Command4

字符串的输出并在 Azure 门户 Bash 环境中执行相同的命令会产生预期结果。但是，当在 C# 中使用相同的输入时，会导致上述错误。

Command4 输出：appconfig 功能过滤器更新 --connection-string <> --feature featureA --filter-name Microsoft.Targeting --filter-parameters 'Audience={"DefaultRolloutPercentage":50,"Groups":[],"用户”：[“用户1”，“用户2”，“用户3”，“用户4”，“用户5”]}'--是

我尝试找到适合此任务的 C# SDK，但不幸的是，我尚未成功确定要使用哪个 SDK。您能帮我找到正确的 SDK 来解决这个问题吗？

您可以使用 Azure.Data.AppConfiguration 包通过 .NET 代码更新 Azure 应用程序配置筛选器。

代码：

using Azure.Data.AppConfiguration;
using System;
using System.Collections.Generic;

var connectionString = "xxxx";
var featureFlag = "featureA";
var filterName = "Microsoft.Targeting";
KeyValuePair<string, object>[] keyValuePairs = new KeyValuePair<string, object>[]
{
    new KeyValuePair<string, object>("DefaultRolloutPercentage", 50),
    new KeyValuePair<string, object>("Users", new string[] { "user1", "user2" }),
    new KeyValuePair<string, object>("Groups", new object[] { })
};
IDictionary<string, object> dictionary = new Dictionary<string, object>();
dictionary.Add("Audience", new Dictionary<string, object>());
foreach (var kvp in keyValuePairs)
{
    ((Dictionary<string, object>)dictionary["Audience"]).Add(kvp.Key, kvp.Value);
}

var client = new ConfigurationClient(connectionString);
var featureFlagSetting = new FeatureFlagConfigurationSetting(featureFlag, isEnabled: true);
var featureflagfilter = new FeatureFlagFilter(filterName, dictionary);
featureFlagSetting.ClientFilters.Add(featureflagfilter);
client.SetConfigurationSetting(featureFlagSetting);

执行上述代码，并使用连接字符串在 Azure 应用程序配置中设置一个名为

featureA

的功能标志，并使用受众定位筛选器。它定义过滤条件，例如

DefaultRolloutPercentage

、

user lists

和

groups

，并更新应用程序配置存储中的配置。
