AutoMapper和JsonPatchDocument的运行路径

Question

我们正在使用 .NET Core 3.1、Microsoft.AspNetCore.JsonPatch 3.1.27 和AutoMapper 12.0.1.

我们正在开发一个 REST API。它公开了一些用于使用 HTTP PATCH 动词更新实体的端点。这些控制器操作接受 DTO 类的 JSON 补丁文档，例如。

JsonPatchDocument<RestApiRequest>

.

[HttpPatch]
public IActionResult UpdateCustomer(JsonPatchDocument<RestApiRequest> req)
{
    return Ok();
}

public class RestApiRequest
{
    public string CustomerName { get; set; }
    public string CompanyAddress { get; set; }
}

我们的 2 个数据库模型看起来像这样（简化）：

public class Customer
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Company Company { get; set; }
}

public class Company
{
    public int Id { get; set; }
    public string Address { get; set; }
}

我们这样配置 AutoMapper：

// RestApiRequest.CompanyAddress is mapped to Address
CreateMap<RestApiRequest, Company>()
    .ForMember(x => x.Address, x => x.MapFrom(y => y.CompanyAddress));
// RestApiRequest.CustomerName is mapped to Name
CreateMap<RestApiRequest, Customer>()
    .ForMember(x => x.Name, x => x.MapFrom(y => y.CustomerName));
CreateMap<JsonPatchDocument<RestApiRequest>, JsonPatchDocument<Company>>();
CreateMap<JsonPatchDocument<RestApiRequest>, JsonPatchDocument<Customer>>();
CreateMap<Operation<RestApiRequest>, Operation<Company>>();
CreateMap<Operation<RestApiRequest>, Operation<Customer>>();

当客户端向其中一个控制器操作发送 HTTP 请求时，我们会得到一个类似于

patch

变量中的对象。然后，我们尝试将它从

JsonPatchDocument<RestApiRequest>

映射到

JsonPatchDocument<Customer>

并保存到

mappedPatch

变量：

var patch = new JsonPatchDocument<RestApiRequest>()
    .Replace(x => x.CustomerName, "New customer name")
    .Replace(x => x.CompanyAddress, "New company address");

var mappedPatch = _mapper.Map<JsonPatchDocument<RestApiRequest>, JsonPatchDocument<Customer>>(patch);

但是，

path

中的

JsonPatchDocument.Operations

没有被映射。

patch

和

mappedPatch

都有相同的路径，这是不正确的：

[
    {
        "value":"New customer name",
        "path":"/CustomerName",
        "op":"replace"
    },
    {
        "value":"New company address",
        "path":"/CompanyAddress",
        "op":"replace"
    }
]

我希望

mappedPatch

的路径是

/Name

和

/Company/Address

.
