在Web API中没有调用操作

Question

我在使用ASP.Net MVC 4 - Web API时遇到了一些问题。

我在API控制器的以下行为：

public void Post([FromBody] Integration integration) 
{ 
    _repository.Add(integration); 
} 

出于某种原因，我对_repository.Add(integration);断点永远不会到来通过。

这是我现在用的是WebClient

POST https://ef52667f-3a6e-4a58-b548-e82b72186b5f.o365apps.net/api/integration HTTP/1.1

在这里张贴在响应我得到：

{"Message":"An error has occurred."} 

有趣的是，我有工作完全正常另一个类似的方法：

public AuthResponse Post([FromBody] AuthRequest authRequest) 
{ 
    var authResponse = new AuthResponse(); 

    try 
    { 
     . . . 
    } 
    catch (Exception e) 
    { 
     authResponse.Success = false; 
     authResponse.Message = e.Message; 
    } 

    return authResponse; 
} 

我在这里错过了什么吗？

仅供参考，在这里我Integration型号：

[SharePointList("Integrations")] 
public class Integration : Entity 
{ 
    public Integration(int id) : base(id) { } 

    public Integration() { } 

    [Required] 
    public string ApiUrl { get; set; } 

    [Required] 
    public bool DeletionAllowed { get; set; } 

    [Required] 
    public bool IncomingAllowed { get; set; } 

    [IgnoreDataMember] 
    [Required] 
    public Guid IntegrationId { get; set; } 

    [IgnoreDataMember] 
    [Required] 
    public string Key { get; set; } 

    [Required] 
    public string ListName { get; set; } 

    [Required] 
    public bool OutgoingAllowed { get; set; } 

    [Required] 
    public string RemoteWeb { get; set; } 

    [Required] 
    public string Web { get; set; } 

    public override object this[string property] 
    { 
     get { return GetType().GetProperty(property).GetValue(this, null); } 
     set 
     { 
      if (property.Equals("Id")) throw new Exception("Cannot set Id through an indexer."); 

      if (property.Equals("IntegrationId")) 
      { 
       IntegrationId = new Guid((string) value); 
       return; 
      } 

      if (property.Equals("Title")) 
      { 
       Key = value as string; 
       return; 
      } 

      PropertyInfo propertyInfo = GetType().GetProperty(property); 
      if (propertyInfo == null) throw new Exception(property + " is not a valid property."); 

      propertyInfo.SetValue(this, value, null); 
     } 
    } 
} 

Entity.cs

public abstract class Entity : IEntity 
{ 
    protected Entity(int id) 
    { 
     Id = id; 
    } 

    protected Entity() { } 

    [IgnoreDataMember] 
    public int Id { get; private set; } 

    public abstract object this[string property] { get; set; } 
} 

IEntity.cs

public interface IEntity 
{ 
    int Id { get; } 

    object this[string property] { get; set; } 
}

涉及将d解决方案您的类/属性顶部的ataContract/DataMember属性不是问题的正确解决方案。

你需要做摆脱WCF残余的是什么：

添加到您的Global.asax：

 GlobalConfiguration.Configuration.Services.RemoveAll(typeof(ModelValidatorProvider), v => v is InvalidModelValidatorProvider); 
     GlobalConfiguration.Configuration.Formatters.JsonFormatter.RequiredMemberSelect‌or = new SuppressRequiredMemberSelector(); 

创建SupressRequiredMemberSelector类：

public class SuppressRequiredMemberSelector : IRequiredMemberSelector 
{ 
    public bool IsRequiredMember(MemberInfo member) 
    { 
     return false; 
    } 
} 

这将解决您的问题无需更改注释，并被广泛接受的Web API的“错误修复”，因为它使用它提供的可扩展性，没有别的。
