可能重复:
Java中的序列化版本uid

我们知道Java序列化机制会忽略静态字段.如果是这样,那么解串器如何知道序列化器的serialVersionUID.serialVersionUID始终是要序列化的类的静态字段.谢谢您的帮助.

数据看起来像:

sport[]=1&music[]=0&web[]=2

我做了:

$data = unserialize($post["data"]);

但这是一个错误:

ErrorException [ 8 ]: unserialize() [function.unserialize]: Error at offset 0 of 27 bytes ~ APPPATH\classes\controller\ajax.php [ 14 ]

我有以下方法:

    [HttpPost]
    public ActionResult GetData()
    {
        var data= (dynamic)null;
        using (DBContext context = new DBContext())
        {
            data= context.MyObject.Where(i=> i.TypeId == 1).OrderBy(k => k.Name).Select(w => new
            {
                description = w.Description
            }).ToList();       
        }

        return Json(data, JsonRequestBehavior.AllowGet);
    }

所以我想将数据正确转换为json对象,但我不确定我是否正确.返回的数据应该在javascript中使用.

我有很多谷歌,我找到了如下的例子,也许我应该做类似的事情,但我不知道如何:

var keyValues = new Dictionary<string, string>
               {
                   { "emailSend", textBox1.Text },
                   { "toEmail", textBox2.Text }
               };

JavaScriptSerializer js = new JavaScriptSerializer();
string json = js.Serialize(keyValues);
MessageBox.Show(json);

I have written a desktop application which is JavaFX based, developed on NetBeans 7.4. I'm using Glassfish to pool jdbc connections and JMS traffic. Development is on a Win 7 64bit system, using 64bit java 1.7_51. One of my users has a 32bit win 7 machine, and the application refuses to run correctly on his machine. There are actually 2 glassfish servers, each providing data connectivity from a different logical company. All of the server code on the two glassfish …

无法在C#中序列化json

我在C#中的代码是 -

string json = "contains json";
YahooContactsData contacts1 = JsonConvert.DeserializeObject<YahooContactsData>(json)

我用过的课程 -

public class YahooContactsData
{
    public YContacts contacts; 
}
public class YContacts
{
    public YContact contact { get; set; }
}
public class YContact
{
    public List<YFields> fields { get; set; }
}
public class YFields
{
    public int id { get; set; }
    public string type { get; set; }
}

假设我有如下 Django 模型：

class Car(models.Model):
    name = models.CharField()
    model = models.CharField()
    type = models.CharField()

class Scooter(models.Model):
    name = models.CharField()
    model = models.CharField()
    type = models.CharField()

class User(models.Model):
    name = models.CharField()
    car = models.ForeignKeyField()
    scooter = models.ForeignKeyField()

和序列化程序如下：

class CarSerializer(serializer.ModelSerializer):
    class Meta:
    model = Car
    fields = (
        'name',
        'model',
        'type'

    )

class ScooterSerializer(serializer.ModelSerializer):
    class Meta:
    model = Scooter
    fields = (
        'name',
        'model',
        'type'

    )


class UservehicleCreateSerializer(serializer.ModelSerializer):
    car = serializers.PrimaryKeyRelatedField(read_only=True)
    scooter = serializers.PrimaryKeyRelatedField(read_only=True)
    class Meta:
    model = User
    fields = …

这是我制作查询集的 csv 文件的函数

我在一次采访中被要求序列化数据（因此它可以存储在缓冲区中并通过某个网络发送）。这就是我想出的-

struct AMG_ANGLES {
    float yaw;
    float pitch;
    float roll;
};

char b[sizeof(struct AMG_ANGLES)];

char* encode(struct AMG_ANGLES *a)
{

    std::memcpy(b, &a, sizeof(struct AMG_ANGLES));
    return b;
}

void decode(char* data)
{
 // check endianess   
    AMG_ANGLES *tmp; //Re-make the struct
    std::memcpy(&tmp, data, sizeof(tmp));
}

这样对吗？任何人都可以提供替代设计吗？我没有收到回电，所以我只是想了解我可以改进的地方。

请使用此序列化 Python 3.11，目标是

{"name": "One", "quantity": 2, "students":[{"first_name": "Geeky", "last_name": "Guy"},{"first_name": "GFG", "last_name": "ocks"}] }

class Student():
    def __init__(self):

class Team():

student1 = Student()
student1.first_name='Geeky'
student1.last_name='Guy'
student2 = Student()
student2.first_name='GFG'
student2.last_name='ocks'
team = Team()
team.name='One'
team.quantity=2
team.students=[]
team.students.append(student1)
team.students.append(student2)
