ModelBinding不反序列化JSON

我使用MVC 5，網頁API 2與實體框架6 VS 2012ModelBinding不反序列化JSON

我能夠成功調用正確的行動在我的web API控制器，但傳入的JSON是永遠反序列化，或者至少不正確。 modelBinding認識到請求中的json與Post動作的參數Type匹配，但每個屬性都爲null或缺省值。

爲什麼json沒有被反序列化？我在這裏看不到任何問題。

這不是一個有效的網址，只是在我的本地

     "title" : "Target: 40 million credit cards compromised", 
     "description" : "The Secret Service is investigating a reported credit card data breach at discount retailer Target.",

控制器：

public class ScabsController : ApiController { 

    private ScabStore _store; 

    private ScabStore store { 
     get { return _store = _store ?? new ScabStore(); } 
    } 

    // POST api/scabs 
    public void Post(Scab scab) { 
     store.scabRepository.save(scab); 
     store.commit(); 
    } 
}

赤黴病類型

public class Scab { 
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)] 
    public int id { get; set; } 

    [DataType(DataType.Url)] 
    public string url { get; set; } 
    public string title { get; set; } 
    public string description { get; set; } 
    public string site { get; set; } 
    public virtual Category category { get; set; } 
    public virtual Image image { get; set; } // Complex Type 
    public virtual User postedBy { get; set; } 
    public virtual ICollection<Score> scores { get; set; } 
    public virtual ICollection<Comment> comments { get; set; } 

    public Scab() { 
     scores = new List<Score>(); 
     comments = new List<Comment>(); 
    } 
}

我也應該注意到，Image屬性是一個ComplexType

在你的客戶端刪除''「scab」：{'屬性，這樣你的json數據應該是這樣的：'{ 「url」：... 「title」...}' – nemesv

就是這樣。你應該提交這個答案，以便我可以給你信用。謝謝 – bflemi3

您的JSON數據與您的C＃模型不匹配。

所以，你需要刪除不必要的"scab"財產，你的數據應該是這樣的：

{ 
    "url" : "http://money.cnn.com/2013/12/18/news/companies/target-credit-card/index.html?iid=Lead", 
    "title" : "Target: 40 million credit cards compromised", 
    "description" : "The Secret Service is investigating a reported credit card data breach at discount retailer Target.", 
    "image" : { 
     "height" : 367, 
     "width" : 620, 
     "url" : "http://i2.cdn.turner.com/money/dam/assets/131128213407-black-friday-target-pa-620xa.jpg" 
    }, 
    "category" : null 
}

或者，如果你不能改變客戶端修改你的C＃的行動代碼：

public void Post(SaveScabModel scabModel) { 
    store.scabRepository.save(scabModel); 
    store.commit(); 
}

其中SaveScabModel只是將Scab模型包含在c＃端還具有「額外」結疤：

public class SaveScabModel { 
    public Scab Scab { get; set; } 
}
