Java 完整调用示例（HttpClient）

依赖 Maven

xml

<!-- httpclient --> <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.14</version> </dependency> <!-- commons-codec MD5 --> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.15</version> </dependency>

核心代码

java

运行

import org.apache.commons.codec.digest.DigestUtils; import org.apache.http.client.methods.CloseableHttpResponse; import org.apache.http.client.methods.HttpPost; import org.apache.http.entity.ContentType; import org.apache.http.entity.StringEntity; import org.apache.http.impl.client.CloseableHttpClient; import org.apache.http.impl.client.HttpClients; import org.apache.http.util.EntityUtils; import java.util.*; public class JdGoodsDetailApi { // 替换为自己的密钥 private static final String APP_KEY = "你的appKey"; private static final String APP_SECRET = "你的appSecret"; private static final String API_URL = "https://api.jd.com/routerjson"; // 商品详情接口方法 private static final String METHOD = "jd.union.open.goods.jingfen.query"; public static void main(String[] args) throws Exception { // 1.业务入参，skuId为京东商品SKU编号 Map<String, Object> bizParam = new HashMap<>(); bizParam.put("skuId", 100012345678); // 目标商品SKU bizParam.put("goodsType", 0); // 2.组装全部参数 Map<String, String> allParams = new TreeMap<>(); allParams.put("app_key", APP_KEY); allParams.put("timestamp", new Date().toLocaleString()); allParams.put("v", "1.0"); allParams.put("method", METHOD); allParams.put("format", "json"); // 业务参数转JSON字符串 allParams.put("param_json", new com.alibaba.fastjson.JSONObject(bizParam).toString()); // 3.生成MD5签名 String sign = getSign(allParams); allParams.put("sign", sign); // 4.POST请求 String result = doPost(allParams); System.out.println("接口返回结果：" + result); } // 生成签名 private static String getSign(Map<String, String> params) { StringBuilder sb = new StringBuilder(APP_SECRET); for (Map.Entry<String, String> entry : params.entrySet()) { sb.append(entry.getKey()).append(entry.getValue()); } sb.append(APP_SECRET); return DigestUtils.md5Hex(sb.toString()).toUpperCase(); } // 发送Post请求 private static String doPost(Map<String, String> params) throws Exception { CloseableHttpClient httpClient = HttpClients.createDefault(); HttpPost httpPost = new HttpPost(API_URL); httpPost.setEntity(new StringEntity(new com.alibaba.fastjson.JSONObject(params).toString(), ContentType.APPLICATION_JSON)); CloseableHttpResponse response = httpClient.execute(httpPost); String resp = EntityUtils.toString(response.getEntity(), "UTF-8"); response.close(); httpClient.close(); return resp; } }

三、PHP 调用实例

php

运行

<?php $appKey = '你的appKey'; $appSecret = '你的appSecret'; $method = 'jd.union.open.goods.jingfen.query'; $url = 'https://api.jd.com/routerjson'; // 业务参数 $bizData = [ 'skuId' => 100012345678, 'goodsType' => 0 ]; $paramJson = json_encode($bizData); // 公共参数 $params = [ 'app_key' => $appKey, 'timestamp' => date('Y-m-d H:i:s'), 'v' => '1.0', 'method' => $method, 'format' => 'json', 'param_json' => $paramJson ]; // 字典排序 ksort($params); $str = $appSecret; foreach ($params as $k => $v) { $str .= $k . $v; } $str .= $appSecret; $sign = strtoupper(md5($str)); $params['sign'] = $sign; // curl请求 $ch = curl_init($url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params)); curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $res = curl_exec($ch); curl_close($ch); echo $res; ?>

四、返回核心字段说明（联盟详情接口）

成功返回 JSON 核心节点：

1. jingfenGoodsInfo商品主体信息
   • skuId：商品 ID
   • skuName：商品标题
   • price：售价、originPrice：原价
   • mainImage：主图地址，galleryImages：图集
   • brandName：品牌，category：类目
2. couponInfo优惠券信息（面额、门槛、链接）
3. commissionInfo佣金比例（联盟推广佣金）
