Question

我正在尝试使用breeze将新添加的实体作为批处理请求发布到我的odata v3 web api，但应该传递给我的odata post方法的实体始终为null。

我的批量路线配置：

config.Routes.MapODataServiceRoute(
    routeName: "odata",
    routePrefix: "odata",
    model: builder.GetEdmModel(),
    batchHandler: new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer)
 );

我的控制器发布方法接收带有空权限的呼叫：

public IHttpActionResult Post([FromBody]ApiUserEntity apiUserEntity)
{
    if (apiUserEntity == null)
       return BadRequest(ModelState);
}

实体：

public class BaseEntity
{
    public int Id { get; set; }
    public DateTime CreatedAt { get; set; }
}

public class ApiUserEntity : BaseEntity
{
    public string Username { get; set; }
    public string Password { get; set; }
    public string Email { get; set; }
    public string Salt { get; set; }

    public ApiUserRole Role { get; set; }

    public ApiPermission Permission { get; set; }
}

enum ApiUserRole {
    Admin,
    Staff,
    User
}
enum ApiPermission {
    Read,
    Write,
    ReadWrite
}

我如何使用breeze调用savechanges的简化代码

manager.createEntity('ApiUserEntity',
                                   { 
                                       Id: 1,
                                       Username: "user",
                                       Password: "password",
                                       Email: "Email", 
                                       Salt: "Salt",
                                       Role: "1",
                                       Permission: "1"
                                    });
manager.saveChanges();

当我用fiddler检查请求时，我发现它正在发送我用breezejs添加的正确数据：

当我调试时，控制器上的post方法被击中，但实体始终为null。我正在使用实体框架，并使用conventionmodelbuilder在webapi上生成元数据。

我找到了解决方法。我的控制器来自Odata控制器。一旦我将其更改为Apicontroller，我的批处理请求就可以了！不知道为什么。也可能失去了odata控制器提供的大量功能。因此需要调试一些以找到实际原因。

批处理请求实体始终为null
