Question

我从ASP.NET Web API返回JSON。 Json确实返回没有问题，但在Json数组的开头，我没有在android应用程序中使用的对象名称。

无论如何设置它？

这里是正在返回的Json

对象名称应该在开始。不仅仅是以ID开头

[{"ID":1197,"CustomerGuid":"ea0af124-ab88-45d8-88f7-3f122ef53c04","UserTrackingID":"2624","EmailAddress":"m.mashoodtariq@gmail.com","Password":"Pakistan99","IsBusiness":null,"FullName":"Mashood","DateRegistered":"2014-11-26T18:51:47.977","PostCode":"44000","BusinessName":null,"FactualID":null,"FacebookToken":null,"Country":null},{"ID":1202,"CustomerGuid":"30c3781e-506c-490a-a27d-03a29696bdcd","UserTrackingID":"2643","EmailAddress":"customer@hotmail.com","Password":"george69","IsBusiness":null,"FullName":"Pending Customer","DateRegistered":"2014-11-27T08:08:04.29","PostCode":"4220","BusinessName":null,"FactualID":null,"FacebookToken":null,"Country":null},{"ID":1203,"CustomerGuid":"cf7d09e4-2e84-4b16-b38c-d32579d1c6c4","UserTrackingID":"2646","EmailAddress":"tesr@hotmail.com","Password":"george69","IsBusiness":true,"FullName":"tester","DateRegistered":"2014-11-28T00:12:40.523","PostCode":"4102","BusinessName":"tester","FactualID":null,"FacebookToken":null,"Country":null}]


Public Class UsersController
    Inherits System.Web.Http.ApiController

    Private db As New PushStateNovember7Entities
    ' GET: api/Users
    Function GetUsers() As IQueryable(Of User)
        Return db.Users
    End Function

End Class

不确定为什么一开始就需要一个名字。如果你只需要解析Android中的Json数组，你可以这样做：

假设您有以下用户类：

public class User {
    private string _ID;
    private string _CustomerGuid;
    //and so on

    public string setID(string Id){ _ID = Id;} 
    public string getID(){ return _ID;}

    public string setCustomerGuid(string customerGuid){ _CustomerGuid = customerGuid;} 
    public string getCustomerGuid(){ return _CustomerGuid;}
}

要获取/解析Json数组，您可以执行以下操作：

JSONArray array = new JSONArray(yourApiReturnedJsonStringHere);
ArrayList<User> users = new ArrayList<User>();

for (int i=0; i < array.length(); i++) {
    User user = new User();

    JSONObject jObj = array.getJSONObject(i);

    user.setID(jObj.getString("ID"));
    user.setCustomerGuid(jObj.getString("CustomerGuid"));
    //.....

    users.add(user);
}

Answer 2

你可以试试这个

 var response = new ApiResponse<T>();
 response.Data = db.Users;
 return response;

这会将您的列表封装在数据名称

中

如果您不使用API控制器，则只需创建Response类和

public Response<T> : where T : class
{
  public T Data {get; set;}
}

return new Response<IList<Users>>() { Data = db.Users};
