C#接入vault方法

在C#中接入Vault的方法有多种。以下是其中两种常用的方式：

1. 使用HashiCorp Vault .NET客户端库（VaultSharp）进行接入：

   using System;
   using VaultSharp;
   using VaultSharp.Core;
    
   class Program
   {
       static void Main(string[] args)
       {
           // 创建VaultClient对象并配置连接信息
           var vaultConfig = new VaultConfigurationBuilder()
               .WithAddress("http://localhost:8200") // Vault服务器地址
               .Build();
           
           using (var client = new VaultClient(new HttpClient(), vaultConfig))
           {
               try
               {
                   // 登录到Vault
                   var loginResponse = client.Auth().LoginAsync(new UserPassAuthenticationInfo
                   {
                       UserName = "your-username",
                       Password = "your-password"
                   }).Result;
               
                   if (!loginResponse.IsSuccessful())
                   {
                       Console.WriteLine($"Failed to authenticate with Vault: {loginResponse.ErrorMessage}");
                       return;
                   }
               
                   // 获取访问令牌
                   string token = loginResponse.Data["auth"]["client_token"];
               
                   // 设置访问令牌为默认身份验证标头
                   client.SetDefaultToken(token);
               
                   // 调用Vault API进行操作
                   var secretResponse = client.Secrets.KV.ReadSecretAsync("secret/myapp").Result;
               
                   if (!secretResponse.IsSuccessful())
                   {
                       Console.WriteLine($"Failed to read secret from Vault: {secretResponse.ErrorMessage}");
                       return;
                   }
               
                   // 处理返回结果
                   foreach (var kv in secretResponse.Data["data"])
                   {
                       Console.WriteLine($"Key: {kv.Key}, Value: {kv.Value}");
                   }
               }
               catch (Exception ex)
               {
                   Console.WriteLine($"An error occurred while interacting with Vault: {ex.Message}");
               }
           }
       }
   }

    

   2. 直接通过HTTP发送REST请求来与Vault交互：

      using System;
      using System.Net.Http;
      using Newtonsoft.Json;
       
      class Program
      {
          static async Task Main(string[] args)
          {
              const string url = "http://localhost:8200"; // Vault服务器地址
          
              // 构造API路由和参数
              var apiRoute = "/v1/auth/userpass/login";
              var requestBody = JsonConvert.SerializeObject(new { username = "your-username", password = "your-password" });
          
              // 创建HttpClient并添加必要的Header
              using (var httpClient = new HttpClient())
              {
                  httpClient.BaseAddress = new Uri(url);
                  httpClient.DefaultRequestHeaders.Add("X-Vault-Token", "your-access-token");
          
                  // 发送POST请求并等待响应
                  var response = await httpClient.PostAsJsonAsync(apiRoute, requestBody);
          
                  // 确保成功收到响应
                  if (response.StatusCode == System.Net.HttpStatusCode.OK)
                  {
                      // 从响应内容中提取所需信息
                      var content = await response.Content.ReadAsStringAsync();
                      dynamic result = JsonConvert.DeserializeObject<dynamic>(content);
          
                      // 处理返回结果
                      string accessToken = result["auth"]["client_token"].ToString();
                      Console.WriteLine($"Access Token: {accessToken}");
                  }
                  else
                  {
                      Console.WriteLine($"Failed to authenticate with Vault: Status Code - {response.StatusCode}");
                  }
              }
          }
      }
