Question

据我所知，我应该在我的SQL数据库Commits表的Payload列中显示JSON，但是我有一个很长的十六进制字符串。

我的电汇代码是根据样本进行以下编辑：

private static IStoreEvents WireupEventStore()
{
        return Wireup.Init()
        .LogToOutputWindow()
        .UsingInMemoryPersistence()
        .UsingSqlPersistence("EventStore") // Connection string is in app.config
            .WithDialect(new MsSqlDialect())
            .EnlistInAmbientTransaction() // two-phase commit
            .InitializeStorageEngine()
            .UsingJsonSerialization()
        .HookIntoPipelineUsing(new[] { new AuthorizationPipelineHook() })
        .UsingSynchronousDispatchScheduler()
            .DispatchTo(new DelegateMessageDispatcher(DispatchCommit))
        .Build();
}

知道如何获取JSON并使调试更容易吗？

只需创建以下视图：

CREATE VIEW [dbo].[DeserializedCommits]
    AS 
    SELECT 
         [StreamId]
        ,[StreamRevision]
        ,[Items]
        ,[CommitId]
        ,[CommitSequence]
        ,[CommitStamp]
        ,[Dispatched]
        ,CAST([Headers] AS VARCHAR(MAX)) AS [Headers]
        ,CAST([Payload] AS VARCHAR(MAX)) AS [Payload]
    FROM [dbo].[Commits]

您可以使用LIKE列上的Payload查询您的活动商店以查找特定活动。

与此类似的查询将获取Payload列的字符串内容：

Commits
.Select(c => System.Text.Encoding.UTF8.GetString(c.Payload.ToArray()))
.ToList();

EventStore仅在Payload列中显示十六进制字符串
