Mongodb Bson类型为Json

Question

我正在用Postman测试我的asp.net core 2.2 Web api。我像这样（httppatch）手动编写JSON：

{
    "query": "{\"name\": \"foo\"}",

    "update": [ "{\"$set\":{\"name\":\"foo2\"}}","{\"$set\":{\"path\": \"foo2 path\"}}" ]
}

现在，我正在考虑如何在客户端上构建补丁主体。我的问题是如何在json中获得等效的代码，使其看起来像我手动编写的代码？

var query = Builders<T>.Filter.Eq(e => e.name, "foo");
var updates = Builders<T>.Update.Set(e => e.name, "foo2").Set(e => e.Path, "foo2 path");

我想这全都与序列化有关，我知道该怎么做？

- 更新 -

我找到了这个：

var serializerRegistry = BsonSerializer.SerializerRegistry;
var documentSerializer = serializerRegistry.GetSerializer<T>();
var upList = updates.Render(documentSerializer, serializerRegistry);

但它仅获取将所有集合组合为一个的最后一个集合（我的糟糕，多亏@Simon Mourier指出了我的错误！）

Answer 1

这是解决方案：

在客户端

        // serializer
        var serializerRegistry = BsonSerializer.SerializerRegistry;
        var documentSerializer = serializerRegistry.GetSerializer<T>();

        // filter and update
        var filter = Builders<T>.Filter.Eq(e => e.Level, 2);
        var updates = Builders<T>.Update
                     .Set(e => e.Name, "foo2")
                     .Set(e => e.Path, "foo2 path")
                     .Inc(e => e.Level, 1);

        // get the string of the filter and the update
        var filterString = filter.Render(documentSerializer, serializerRegistry);
        var updateString = updates.Render(documentSerializer, serializerRegistry);

        // instantiate patch object with properties to json
        Patch patch = new Patch()
        {
            Query = filterString.ToJson(),
            Update = updateString.ToJson()
        };

        // patch object to json
        var patchJson = patch.ToJson();

在服务器端

    [HttpPatch]
    public async Task<IActionResult> PatchOne([FromBody]Patch patch)
    {
        // don't need to ModelState.isValid, it's done on binding
        
        try
        {
            var update = BsonDocument.Parse(patch.Update);
            var filter = BsonDocument.Parse(patch.Query);

            var result = await _serviceBase.UpdateOneAsync(filter, update);
            
            ...

        }
        catch (System.Exception ex)
        {

            return StatusCode(StatusCodes.Status500InternalServerError, ex.Message.ToJson());
        }
    }

全局模态（我的解决方案结构）

public class Patch
{
    [Required]
    public string Query { get; set; }
    [Required]
    public string Update { get; set; }
}
