Ajax來.NET無法綁定多個參數誤差

當我嘗試使用Ajax傳遞值是這樣的：Ajax來.NET無法綁定多個參數誤差

$.ajax({ 
    type: "PUT", 
    dataType: 'json', 
    url: "http://localhost:52930/api/person/", 
    contentType: "application/json; charset=utf-8", 
    data: {persoon1, persoon2, file} 
}) 
    .done(function(msg) { 
     alert("Test") 
    });

在其中PERSON1和2是一個對象，和一個文件是一個字節數組（JSON ）。

在.NET

public IHttpActionResult Put(Person personFrom , Person personTo , byte[] file) 
    { 
     if (!ModelState.IsValid) 
     { 
      return BadRequest(); 
     } 
     _personRepository.EncrypFileAndSendToPerson(file, personFrom , personTo); 
     return CreatedAtRoute("DefaultApi", new { controller = "Person", id = personTo.Id }, personTo); 
    }

使用此功能，這是人類：

public class Person 
{ 
    private RSAWithRSAParameterKey _rsaParameters; 
    public Person() 
    { 
     _rsaParameters = new RSAWithRSAParameterKey(); 
     _rsaParameters.AssignNewKey(); 
     PrivateKey = _rsaParameters._privateKey; 
     PublicKey = _rsaParameters._publicKey; 
    } 
    public int Id { get; set; } 
    public string Name { get; set; } 
    public string Password { get; set; } 
    public string Salt { get; set; } 
    public byte[] File { get; set; } 
    public string PrivateKey { get; set; } 
    public string PublicKey { get; set; } 
    public EncryptedPacket Packet { get; set; }  
}

爲什麼我不斷收到這個錯誤，我該如何解決？

最有可能出現這種情況，因爲參數是不可選的，您不會將FromBody屬性應用於參數。試試這個：

public IHttpActionResult Put(
    [FromBody] Person personFrom, 
    [FromBody] Person personTo, 
    [FromBody] byte[] file) 
{ 
    ... 
}

如果沒有幫助嘗試創建新模型映射請求，將包含所有屬性：

public class PutModel 
{ 
    public Person PersonFrom {get; set;} 
    public Person PersonTo {get; set;} 
    public byte[] File {get; set;} 
}

而在你的動作定義一個參數：

public IHttpActionResult Put([FromBody] PutModel model) 
{ 
    ... 
}

並確保屬性名稱正確@Jay建議。

data: { 
    "personFrom": persoon1, 
    "personTo": persoon2, 
    "file": file 
}

此外，基於控制檯中的消息，文件是一個對象，而不是JS中的數組。儘量明確地使一個數組像Converting a JS object to an array：

var array = $.map(file, function(value, index) { 
    return value; 
});

它現在提供400個不好的請求。 –

[[123]，[34]，[49]，[34]，[58]，[49]，[49]，[53]，[44]，[34]，[50]，[34]， [58]，[49]，[48]，[48]，[44]，...]這就是數組現在看起來如此 –

@SinanSamet，數組看起來不對，應該沒有一個值的內部數組。只是簡單的數組。 400是因爲你'返回BadRequest（）;'我想。 –

我收到（該值的數據需要傳遞的價值像這種方式

$.ajax({ 
    type: "PUT", 
    dataType: 'json', 
    url: "http://localhost:52930/api/person/", 
    contentType: "application/json; charset=utf-8", 
    data: { 
     "personFrom": persoon1, 
     "personTo": persoon2, 
     "file": file 
    } 
}) 
     .done(function (msg) { 
      alert("Test") 
     });

仍然給了同樣的錯誤 –

是您的數據是有效的格式化或不？ – Jay

我編輯我的問題，包含我發送的確切數據 –

試試下面的代碼

$.ajax({ 
        type: 'PUT', 
        url: 'http://localhost:52930/api/person/', 
        dataType: 'application/json', 
        data: { 
         personFrom : persoon1, 
         personTo : persoon2, 
         file: file      
        }, 
        success: function (data) { 
         alert("Application Updated Successfully"); 
        }, 
        error: function (err) { 
        } 
       });

你想填充在JavaScript狀物體：

var persoon1 = { 
Id: $("#id").val(), 
Name: $("#Name").val(), 
}

你的方法是這樣的：
