Question

使用JObject将数据传递给webapi，如何对从JObject返回的对象进行模型验证？我正在使用angurlarjs进行绑定，并使用DTO作为我的模型。

Dim db As DAO.Database
Set db = DBEngine.Workspaces(0).OpenDatabase("FullPathAndFileNameOfDb")
db.Execute "qry325_NMC_Final", dbFailOnError
Set db = Nothing

如果要验证输入数据，请考虑使用自定义ActionFilterAttributes进行装饰。

[RequiresJsonBody("SchoolBranch","SchoolPolicy")]
public HttpResponseMessage InsertSchoolBranch(JObject jsonData)
{
    // Stuff...
}

或者可能使用一些元组作为模型

public class RequiresJsonBody : ActionFilterAttribute
{
    private string paramName;

    public RequiresJsonBody (string paramName)
    {
        this.paramName = paramName;
    }

    public override void OnActionExecuting(HttpActionContext actionContext)
    {
        IDictionary<string, string> errors = new Dictionary<string, string>();

        // Validate incoming. Add key / error messages to dictionary...

        foreach (var err in errors)
        {
            actionContext.ModelState.AddModelError(err.Key, err.Value);
        }

        if (!actionContext.ModelState.IsValid
            && errors.Keys.Count > 0)
        {
            actionContext.Response
                = actionContext.Request.CreateErrorResponse(
                    HttpStatusCode.BadRequest,
                    String.Join(" ", errors.Values.ToArray()));
        }
    }
}
