android Retrofit POST无法正常工作-Android Retrofit

Question

这是我的json，我需要发布所有这些

{
      "name": "name",
      "type": "cash",
      "PaymentStatus": true
      "CartItems": [
        {
          "ProductId": 1,
          "ProductName": "sample string 2",
          "Quantity": 3,
          "UnitPrice": 4.1,
          "Price": 5.1
        },{
          "ProductId": 1,
          "ProductName": "sample string 2",
          "Quantity": 3,
          "UnitPrice": 4.1,
          "Price": 5.1
        }
      ]
       }

这是我的Retrofit接口ApiService

@Multipart
    @POST("Addtocart")
    Call<AddtoCartRes> createOrder(@Body Order order,
                                   @HeaderMap HashMap<String,String> headerMap,
                                   @Path("name") String ShopUserName,
                                   @Path("type") String ShopName,
                                   @Path("PaymentStatus") String SalesLogin
                                  );

这是我的Order类@SerializedName（“ CartItems”）List orderDetailList;

    public List<Cart> getOrderDetailList() {
        return orderDetailList;
    }

    public void setOrderDetailList(List<Cart> orderDetailList) {
        this.orderDetailList = orderDetailList;
    }

Answer 1

您的请求模型类应该像这样

public class CartItem {

    private int ProductId;
    private String ProductName;
    private int Quantity;
    private int UnitPrice;
    private int Price;

    public void setProductId(int productId) {
        ProductId = productId;
    }

    public void setProductName(String productName) {
        ProductName = productName;
    }

    public void setQuantity(int quantity) {
        Quantity = quantity;
    }

    public void setUnitPrice(int unitPrice) {
        UnitPrice = unitPrice;
    }

    public void setPrice(int price) {
        Price = price;
    }
}

这是请求模型类

public class MyRequestModel {

    private String name;
    private String type;
    private int PaymentStatus;
    private List<CartItem >  CartItems;

    public void setName(String name) {
        this.name = name;
    }

    public void setType(String type) {
        this.type = type;
    }

    public void setPaymentStatus(int paymentStatus) {
        PaymentStatus = paymentStatus;
    }

    public void setCartItems(List<CartItem> cartItems) {
        CartItems = cartItems;
    }
}

你的Api看起来像这样

@POST("Addtocart")
Call<AddtoCartRes> createOrder(@HeaderMap HashMap<String,String> headerMap,
                                   @Body MyRequestModel order);
