1688按图搜索商品（拍立淘）API返回的数据通常是一个JSON格式的响应，其结构如下：

{
    "code": 200,
    "message": "success",
    "data": {
        "products": [
            {
                "id": "12345",
                "name": "商品名称",
                "price": "100.00",
                "description": "商品描述",
                "imageUrl": "https://example.com/image.jpg",
                "link": "https://1688.com/product/12345"
            },
            {
                "id": "67890",
                "name": "另一个商品名称",
                "price": "200.00",

    }
}

数据结构说明

1. code

   • 返回的状态码。200表示请求成功，其他值表示请求失败。

2. message

   • 请求结果的描述信息，例如"success"表示成功，失败时会返回具体的错误信息。

3. data

   • 包含实际返回的数据，通常是一个对象，内部包含商品列表。

     • id：商品的唯一标识符。

     • name：商品名称。

     • price：商品价格。

     • description：商品描述。

     • imageUrl：商品图片的URL。

     • link：商品详情页的链接。

示例解析

假设API返回上述JSON数据，可以使用Java的Jackson库进行解析，示例如下：

import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.IOException;
import java.util.List;

public class JsonParser {
    public static void main(String[] args) {
        String jsonResponse = "{"
                + "\"code\": 200,"
                + "\"message\": \"success\","
                + "\"data\": {"
                + "    \"products\": ["
                + "        {"
                + "            \"id\": \"12345\","
                + "            \"name\": \"商品名称\","
                + "            \"price\": \"100.00\","
                + "            \"description\": \"商品描述\","
                + "            \"imageUrl\": \"https://example.com/image.jpg\","
                + "            \"link\": \"https://1688.com/product/12345\""
                + "        },"
                + "        {"
                + "            \"id\": \"67890\","
                + "            \"name\": \"另一个商品名称\","
                + "            \"price\": \"200.00\","
                + "            \"description\": \"另一个商品描述\","
                + "            \"imageUrl\": \"https://example.com/image2.jpg\","
                + "            \"link\": \"https://1688.com/product/67890\""
                + "        }"
                + "    ]"
                + "}"
                + "}";

        ObjectMapper objectMapper = new ObjectMapper();
        try {
            ApiResponse response = objectMapper.readValue(jsonResponse, ApiResponse.class);
            if (response.getCode() == 200) {
                List<Product> products = response.getData().getProducts();
                for (Product product : products) {
                    System.out.println("商品ID: " + product.getId());
                    System.out.println("商品名称: " + product.getName());
                    System.out.println("商品价格: " + product.getPrice());
                    System.out.println("商品描述: " + product.getDescription());
                    System.out.println("商品图片URL: " + product.getImageUrl());
                    System.out.println("商品链接: " + product.getLink());
                    System.out.println("----------");
                }
            } else {
                System.out.println("API请求失败: " + response.getMessage());
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    static class ApiResponse {
        private int code;
        private String message;
        private Data data;

        // Getters and Setters
        public int getCode() { return code; }
        public void setCode(int code) { this.code = code; }
        public String getMessage() { return message; }
        public void setMessage(String message) { this.message = message; }
        public Data getData() { return data; }
        public void setData(Data data) { this.data = data; }

        static class Data {
            private List<Product> products;

            public List<Product> getProducts() { return products; }
            public void setProducts(List<Product> products) { this.products = products; }
        }

        static class Product {
            private String id;
            private String name;
            private String price;
            private String description;
            private String imageUrl;
            private String link;

            // Getters and Setters
            public String getId() { return id; }
            public void setId(String id) { this.id = id; }
            public String getName() { return name; }
            public void setName(String name) { this.name = name; }
            public String getPrice() { return price; }
            public void setPrice(String price) { this.price = price; }
            public String getDescription() { return description; }
            public void setDescription(String description) { this.description = description; }
            public String getImageUrl() { return imageUrl; }
            public void setImageUrl(String imageUrl) { this.imageUrl = imageUrl; }
            public String getLink() { return link; }
            public void setLink(String link) { this.link = link; }
        }
    }
}

通过上述代码，可以解析API返回的JSON数据，并提取商品的详细信息。
