mongodb-.net-driver - MongoDB C# - 如何将任意 JSON 文档保存为动态类型？

Question

我正在尝试编写一个通用 Web Api Controller ，它允许我将 JSON 文档保存到集合中，而无需指定 C# 类型。我尝试将代码压缩为要点:

public class PassThroughController : ApiController
{
    [Route("api/mongodb/{collection}")]
    public void Post(string collection, dynamic document)
    {
        const string connectionString = "mongodb://localhost";

        var client = new MongoClient(connectionString);
        var db = client.GetServer().GetDatabase("SampleDb");
        var mongoCollection = db.GetCollection(collection);

        mongoCollection.Save(document,
            new MongoInsertOptions
            {
                WriteConcern = WriteConcern.Acknowledged
            });
        }
}

我正在尝试发布一个简单的文档:

{ id: "2112", name: "Rush" }

但是无论我向该方法发送什么内容，我都会收到类似于以下内容的错误:“Save can only be used with Documents that has an Id.”

我们尝试了许多不同的 Id 属性(Id、id、_id)，但它们都会导致类似的问题。

有什么想法吗？

谢谢

在同事的帮助下，我找到了一个解决方案:

public class PassThroughController : ApiController
{
    [Route("api/mongodb/{collection}")]
    public void Post(string collection, HttpRequestMessage message)
    {
        const string connectionString = "mongodb://localhost";

        var client = new MongoClient(connectionString);
        var db = client.GetServer().GetDatabase("SampleDb");
        var mongoCollection = db.GetCollection(collection);

        var json = message.Content.ReadAsStringAsync().Result;
        var document = BsonSerializer.Deserialize<BsonDocument>(json);

        mongoCollection.Save(document,
            new MongoInsertOptions
            {
                WriteConcern = WriteConcern.Acknowledged
            });
        }
}
