Question

VaultSharp软件包似乎包含了我想要的所有内容，并且有据可查。我试图使用VaultSharp软件包从Vault服务器读取我们的机密。但是我生锈的C＃在下面的“ Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");”行中将我拦住，并显示错误消息：

“ await”运算符只能在异步方法中使用。考虑使用“异步”修饰符标记此方法并进行更改其返回类型为“任务”。

using VaultSharp.V1.AuthMethods.AppRole;
using VaultSharp.V1.AuthMethods;
using VaultSharp.V1.Commons;
using VaultSharp.V1.AuthMethods.Token;

namespace VaultConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            var vaultUrl = "https://vault-server.url.com:443";
            Program.by_token(vaultUrl);

        }

     
       static  void by_token(string vaultUrl)
        {
            // Initialize one of the several auth methods.
            IAuthMethodInfo authMethod = new TokenAuthMethodInfo("s.R2gFHDiup5wCeHHksfc2zKUN");

            // Initialize settings. You can also set proxies, custom delegates etc. here.
            var vaultClientSettings = new VaultClientSettings(vaultUrl, authMethod);

            IVaultClient vaultClient = new VaultClient(vaultClientSettings);

            // Use client to read a key-value secret.
           Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");
        }

    }
}

Answer 1

错误告诉您确切的信息。虽然让我们推断：

“ await”运算符只能在异步方法中使用。 考虑用“ async”修饰符标记此方法并更改其返回值键入“任务” 。

static async Task Main(string[] args)
{
    var vaultUrl = "https://vault-server.url.com:443";
    await Program.by_token(vaultUrl);
}

 
static async Task by_token(string vaultUrl)
{
    ...
    Secret<SecretData> kv2Secret = await vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");
}

这时，您应该对 async and await 模式进行一些研究：

Answer 2

除了使方法异步之外，您还可以删除“ await”，这将使其同步而不是异步。

var kv2Secret = vaultClient.V1.Secrets.KeyValue.V2.ReadSecretAsync("/secret/my_corp/my_app/dev/db_creds");

对您来说最好的选择取决于您的用例，因此我建议像其他答案中所建议的那样先对其进行阅读。
