如何使用Web Api 2接收对象json。我正确发送对象，但在后端我的对象为空。见下文。

我的对象JSON

这是我将在请求中发送的JSON对象。

 //Start APPIUM(CLI) server
        Runtime.getRuntime().exec("cmd.exe /c start cmd.exe /k \"appium -a  0.0.0.0 -p 4723 \"");
        Thread.sleep(10000);
        URL u = new URL("http://0.0.0.0:4723/wd/hub");
        //Give Details of ARD and App under Testing
        DesiredCapabilities dc = new DesiredCapabilities();
        dc.setCapability(CapabilityType.BROWSER_NAME,"chrome");
        dc.setCapability("deviceName","LC4C5Y648825");
        dc.setCapability("platformName","android");
        dc.setCapability("platformVersion", "4.4.2");
        Thread.sleep(8000);
        //Create Driver object for AndroidDriver
        AndroidDriver driver = new AndroidDriver(u,dc);
        Thread.sleep(3000);
        driver.get("https://www.gmail.com");
        Thread.sleep(5000);
        //driver.context("NATIVE_APP");
        Thread.sleep(5000);
        driver.findElement(By.xpath("//*[text()='More options']")).click();
        Thread.sleep(2500);
        driver.findElement(By.xpath("//*[text()='Create account']")).click();
        Thread.sleep(2500);
        driver.findElement(By.name("FirstName")).sendKeys("****");
        driver.findElement(By.name("LastName")).sendKeys("****");
        driver.findElement(By.name("GmailAddress")).sendKeys("*********");
        driver.findElement(By.name("Passwd")).sendKeys("******");
        Thread.sleep(3000);
        driver.findElement(By.name("PasswdAgain")).sendKeys("******");
        Thread.sleep(5000);
        WebElement we = driver.findElement(By.xpath("//*[@class='android.view.View'][@text='Month']"));
        we.isDisplayed();
        we.click();[enter image description here][1]

我的对象。

这是我的映射对象。需要使用请求中收到的JSON对象填充的类。

{
    "ItensRateio" : [
        {
            "TipoColetorCusto" : "1",
            "ColetorCusto" : "MRBHAD",
            "Valor": "R$ 25.22",
            "Descricao": "Rateio do Brasil"
        },
        {
            "TipoColetorCusto" : "1",
            "ColetorCusto" : "MRBHAD",
            "Valor": "R$ 25.22",
            "Descricao": "Rateio do Brasil"
        }
    ]
}

我在WebAPi 2中的方法

public class RateioSimplesRequestModel
{
    List<ItemRateio> ItensRateio { get; set; }
    List<ItemMaterial> ItensMaterial { get; set; }

    public RateioSimplesRequestModel()
    {
        ItensRateio = new List<ItemRateio>();
        ItensMaterial = new List<ItemMaterial>();
    }
}

public class ItemRateio
{
    public string TipoColetorCusto { get; set; }
    public string ColetorCusto { get; set; }
    public string Valor { get; set; }
    public string Descricao { get; set; }
}

public class ItemMaterial
{
    public string CNAE { get; set; }
    public string CodigoMaterial { get; set; }
    public string Descricao { get; set; }
}

我怎么能完美？

Answer 1

您的列表不是公共的，json.net默认只映射公共属性。此外，集合不应公开设置。

public class RateioSimplesRequestModel
{
    public List<ItemRateio> ItensRateio { get; private set; }
    public List<ItemMaterial> ItensMaterial { get; private set; }

    public RateioSimplesRequestModel()
    {
        ItensRateio = new List<ItemRateio>();
        ItensMaterial = new List<ItemMaterial>();
    }
}

Answer 2

请注意，您在list ... json对象的属性中拥有class因此需要正确格式化并且应发送parametro而不是ItensRateio }

 var parametro = {};
 parametro.ItensRateio = [
   {
     "TipoColetorCusto" : "1",
     "ColetorCusto" : "MRBHAD",
     "Valor": "R$ 25.22",
     "Descricao": "Rateio do Brasil"
   },
   {
     "TipoColetorCusto" : "1",
     "ColetorCusto" : "MRBHAD",
     "Valor": "R$ 25.22",
     "Descricao": "Rateio do Brasil"
   }
 ];

Answer 3

正如Oliver所提到的，公开列表应该允许将其转换为对象。

如果您正在使用C＃，验证对象是否可以序列化的一种方法是构造对象并使用 JsonConvert 将其转换为JSON等效对象。这应该突出显示任何成员保护级别问题，并生成预期的JSON。

根据上面的类，这将生成以下JSON：

{
  "ItensRateio": [
    {
      "TipoColetorCusto": "1",
      "ColetorCusto": "MRBHAD",
      "Valor": "R$ 25.22",
      "Descricao": "Rateio do Brasil"
    },
    {
      "TipoColetorCusto": "1",
      "ColetorCusto": "MRBHAD",
      "Valor": "R$ 25.22",
      "Descricao": "Rateio do Brasil"
    }
  ],
  "ItensMaterial": []
}

在WEB API 2中接收对象JSON
