Asp.NETWebAPI中的Post JSON数组

大家好，我是

ASP.netwebapi

新手，我想发布

JSON

数组数据以获取任何响应

我的JSON POST数组格式是

{
    "User_Id":"admi12n@1234","Key_Code":"3F-47-AB-84-9F-EB-D6-6B-9C-62-CC-85-98-4D-28-6B",
    "ProductDetails": [
        {"Product_Id":"ELT-7035","Price":"999","Quantity":"5"},
        {"Product_Id":"ELT-1254","Price":"1024","Quantity":"3"}
    ]
}

我希望得到如下回应

{
    "User_Id":"admi12n@1234","Key_Code":"3F-47-AB-84-9F-EB-D6-6B-9C-62-CC-85-98-4D-28-6B",
    "OrderID":"Ord-021","Name":"Sabyasachi"
    "ProductDetails": [
        {"Product_Id":"ELT-7035","Price":"999","Quantity":"5"},
        {"Product_Id":"ELT-1254","Price":"1024","Quantity":"3"}
    ]
}

public class Order
    {
        [Key]
        public long ID { get; set; }
        public string Order_Id { get; set; }
        public string Product_Id { get; set; }
        public long Quantity { get; set; }
        public long Amount { get; set; }
        public string User_Id { get; set; }
        public string Key_Code { get; set; }
        public DateTime Order_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public class Product
    {
        [Key]
        public int Id { get; set; }
        public string Product_Code { get; set; }
        public string Product_Name { get; set; }
        public string Product_Category { get; set; }
        public string Product_Description { get; set; }
        public string Quantity { get; set; }
        public string Price { get; set; }
        public string Image { get; set; }
        public DateTime Created_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public HttpResponseMessage PostOrder([FromBody] Order_Listing orderData)
{
    orderData = repository.Add(orderData);
    var response = Request.CreateResponse<Order_Listing>(HttpStatusCode.Created, orderData);
    string uri = Url.Link("DefaultApi", new { customerID = orderData.ID });
    response.Headers.Location = new Uri(uri);
    return response;
}

我从发布的

用户Id

生成

OrderID

作为随机变量和

Name

。在这里，我想发布一个订单中的多个产品

我的订单如下

{
    "User_Id":"admi12n@1234","Key_Code":"3F-47-AB-84-9F-EB-D6-6B-9C-62-CC-85-98-4D-28-6B",
    "OrderID":"Ord-021","Name":"Sabyasachi"
    "ProductDetails": [
        {"Product_Id":"ELT-7035","Price":"999","Quantity":"5"},
        {"Product_Id":"ELT-1254","Price":"1024","Quantity":"3"}
    ]
}

public class Order
    {
        [Key]
        public long ID { get; set; }
        public string Order_Id { get; set; }
        public string Product_Id { get; set; }
        public long Quantity { get; set; }
        public long Amount { get; set; }
        public string User_Id { get; set; }
        public string Key_Code { get; set; }
        public DateTime Order_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public class Product
    {
        [Key]
        public int Id { get; set; }
        public string Product_Code { get; set; }
        public string Product_Name { get; set; }
        public string Product_Category { get; set; }
        public string Product_Description { get; set; }
        public string Quantity { get; set; }
        public string Price { get; set; }
        public string Image { get; set; }
        public DateTime Created_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public HttpResponseMessage PostOrder([FromBody] Order_Listing orderData)
{
    orderData = repository.Add(orderData);
    var response = Request.CreateResponse<Order_Listing>(HttpStatusCode.Created, orderData);
    string uri = Url.Link("DefaultApi", new { customerID = orderData.ID });
    response.Headers.Location = new Uri(uri);
    return response;
}

我的产品类别如下

{
    "User_Id":"admi12n@1234","Key_Code":"3F-47-AB-84-9F-EB-D6-6B-9C-62-CC-85-98-4D-28-6B",
    "OrderID":"Ord-021","Name":"Sabyasachi"
    "ProductDetails": [
        {"Product_Id":"ELT-7035","Price":"999","Quantity":"5"},
        {"Product_Id":"ELT-1254","Price":"1024","Quantity":"3"}
    ]
}

public class Order
    {
        [Key]
        public long ID { get; set; }
        public string Order_Id { get; set; }
        public string Product_Id { get; set; }
        public long Quantity { get; set; }
        public long Amount { get; set; }
        public string User_Id { get; set; }
        public string Key_Code { get; set; }
        public DateTime Order_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public class Product
    {
        [Key]
        public int Id { get; set; }
        public string Product_Code { get; set; }
        public string Product_Name { get; set; }
        public string Product_Category { get; set; }
        public string Product_Description { get; set; }
        public string Quantity { get; set; }
        public string Price { get; set; }
        public string Image { get; set; }
        public DateTime Created_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public HttpResponseMessage PostOrder([FromBody] Order_Listing orderData)
{
    orderData = repository.Add(orderData);
    var response = Request.CreateResponse<Order_Listing>(HttpStatusCode.Created, orderData);
    string uri = Url.Link("DefaultApi", new { customerID = orderData.ID });
    response.Headers.Location = new Uri(uri);
    return response;
}

我找不到邮寄订单的最佳方式

public Order Add(Order odrerDetails) //This will not give array of data for products
{
    using (var context = new EcommerceDBContext())
    {            
        odrerDetails.Order_Id = Helper.Random(7); //Generate random orderID from my class
        odrerDetails.Created_Date = DateTime.Now;
        odrerDetails.Modified_Date = DateTime.Now;
        //How to Save other details
        context.objOrderListing.Add(odrerDetails);
        context.SaveChanges();
        return odrerDetails;
    }
}

在API控制器中，我的代码如下

{
    "User_Id":"admi12n@1234","Key_Code":"3F-47-AB-84-9F-EB-D6-6B-9C-62-CC-85-98-4D-28-6B",
    "OrderID":"Ord-021","Name":"Sabyasachi"
    "ProductDetails": [
        {"Product_Id":"ELT-7035","Price":"999","Quantity":"5"},
        {"Product_Id":"ELT-1254","Price":"1024","Quantity":"3"}
    ]
}

public class Order
    {
        [Key]
        public long ID { get; set; }
        public string Order_Id { get; set; }
        public string Product_Id { get; set; }
        public long Quantity { get; set; }
        public long Amount { get; set; }
        public string User_Id { get; set; }
        public string Key_Code { get; set; }
        public DateTime Order_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public class Product
    {
        [Key]
        public int Id { get; set; }
        public string Product_Code { get; set; }
        public string Product_Name { get; set; }
        public string Product_Category { get; set; }
        public string Product_Description { get; set; }
        public string Quantity { get; set; }
        public string Price { get; set; }
        public string Image { get; set; }
        public DateTime Created_Date { get; set; }
        public DateTime Modified_Date { get; set; }
    }

public HttpResponseMessage PostOrder([FromBody] Order_Listing orderData)
{
    orderData = repository.Add(orderData);
    var response = Request.CreateResponse<Order_Listing>(HttpStatusCode.Created, orderData);
    string uri = Url.Link("DefaultApi", new { customerID = orderData.ID });
    response.Headers.Location = new Uri(uri);
    return response;
}

public HttpResponseMessage PostOrder（[FromBody]Order\u列出orderData）
{
orderData=repository.Add（orderData）；
var response=Request.CreateResponse（HttpStatusCode.Created，orderData）；
字符串uri=Url.Link（“DefaultApi”，新的{customerID=orderData.ID}）；
response.Headers.Location=新Uri（Uri）；
返回响应；
}

请帮助我如何实现这一点。

您的代码有几个问题：

您的

订单

和

产品

类不反映 你的JSON

Order

类以1:1的比例包含产品详细信息 关系基于JSON，我假设您想要1:n关系

JSON中的属性必须与 在类中，否则它们将不会被映射

将您的类更改为以下内容，它应该会起作用。 当然，您也可以更改JSON中的属性名称

如果您不能或不想更改您的属性名称，请考虑使用DTOS < /P>

public class Order
{
    public string User_Id { get; set; }
    public string Key_Code { get; set; }
    public string OrderID { get; set; }
    public string Name { get; set; }
    public List<Product> ProductDetails { get; set; }
    // add the rest of your properties
}

public class Product
{
    public string Product_Id { get; set; }
    public string Price { get; set; }
    public string Prd_Qty { get; set; }
    // add the rest of your properties
}

Api方法的签名看起来是错误的。什么是订单清单？这应该是

订单

，除非它是DTO，否则在这种情况下，您需要一种方法从

订单列表

获取

订单

public HttpResponseMessage PostOrder([FromBody] Order orderData)
{
    orderData = repository.Add(orderData);
    var response = Request.CreateResponse<Order_Listing>(HttpStatusCode.Created, orderData);
    string uri = Url.Link("DefaultApi", new { customerID = orderData.ID });
    response.Headers.Location = new Uri(uri);
    return response;
}

公共HttpResponseMessage PostOrder（[FromBody]Order orderData）
{
orderData=repository.Add（orderData）；
var response=Request.CreateResponse（HttpStatusCode.Created，orderData）；
字符串uri=Url.Link（“DefaultApi”，新的{customerID=orderData.ID}）；
response.Headers.Location=新Uri（Uri）；
返回响应；
}

还有几句话：

如果它确实是1:n关系，那么您可能需要一个属性

Product.OrderId

除列表外，

订单

类不应引用任何

产品

数量

和

价格

很可能不是

字符串

，而是数值，例如

十进制

如果

Order.ID

是您的主键，那么拥有

Order.ID

确实令人困惑。考虑将其重命名为<代码>订单。

我根据您的要求进行了更改，我的公共订单添加（订单详细信息）方法是什么？
