JSON格式Python，Java,PHP等封装获取淘宝商品快递费用数据API方法

**淘宝商品快递费用数据API封装**

淘宝作为中国最大的电子商务平台之一，其商品信息包括价格、描述、图片等多个方面。其中，快递费用是用户关心的重要信息之一。为了方便获取淘宝商品快递费用数据，我们可以使用淘宝开放平台提供的API接口。

在本文中，我们将介绍如何使用Python、Java和PHP语言封装淘宝商品快递费用数据API方法。

### **1. 淘宝开放平台注册**

首先，需要在淘宝开放平台注册一个开发者账号。注册完成后，可以申请到AppKey和AppSecret等必要参数。

### **2. Python封装**

使用Python语言封装淘宝商品快递费用数据API方法，我们可以使用requests库来发送HTTP请求。

import requestsclass TaobaoApi:
 def __init__(self, app_key, app_secret):
 self.app_key = app_key self.app_secret = app_secret def get_express_fee(self, item_id):
 url = " /> params = {
 "item_id": item_id,
 "app_key": self.app_key,
 "timestamp": int(time.time())
 }
 headers = {
 "Authorization": f"Bearer {self.get_token()}"
 }
 response = requests.get(url, params=params, headers=headers)
 return response.json()

 def get_token(self):
 url = " /> data = {
 "grant_type": "client_credentials",
 "app_key": self.app_key,
 "timestamp": int(time.time())
 }
 headers = {
 "Content-Type": "application/x-www-form-urlencoded"
 }
 response = requests.post(url, data=data, headers=headers)
 return response.json()["access_token"]

# 使用示例taobao_api = TaobaoApi("your_app_key", "your_app_secret")
express_fee = taobao_api.get_express_fee("your_item_id")
print(express_fee)

javaimport ok />import ok />import ok />
public class TaobaoApi {
 private String appKey;
 private String appSecret;

 public TaobaoApi(String appKey, String appSecret) {
 this.appKey = appKey;
 this.appSecret = appSecret;
 }

 public String getExpressFee(String itemId) throws Exception {
 OkHttpClient client = new OkHttpClient();
 Request request = new Request.Builder()
 .url(" /> .post(new FormBody.Builder()
 .add("item_id", itemId)
 .add("app_key", appKey)
 .build())
 .header("Authorization", "Bearer " + getToken())
 .build();
 Response response = client.newCall(request).execute();
 return response.body().string();
 }

 private String getToken() throws Exception {
 OkHttpClient client = new OkHttpClient();
 Request request = new Request.Builder()
 .url(" /> .post(new FormBody.Builder()
 .add("grant_type", "client_credentials")
 .add("app_key", appKey)
 .build())
 .header("Content-Type", "application/x-www-form-urlencoded")
 .build();
 Response response = client.newCall(request).execute();
 return response.body().string();
 }

 public static void main(String[] args) throws Exception {
 TaobaoApi taobaoApi = new TaobaoApi("your_app_key", "your_app_secret");
 String expressFee = taobaoApi.getExpressFee("your_item_id");
 System.out.println(expressFee);
 }
}

phpclass TaobaoApi {
 private $appKey;
 private $appSecret;

 public function __construct($appKey, $appSecret) {
 $this->appKey = $appKey;
 $this->appSecret = $appSecret;
 }

 public function getExpressFee($itemId) {
 $url = " /> $params = array(
 "item_id" => $itemId,
 "app_key" => $this->appKey );
 $headers = array(
 "Authorization: Bearer " . $this->getToken()
 );
 $ch = curl_init($url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_POSTFIELDS,  /> curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
 $response = curl_exec($ch);
 return json_decode($response, true);
 }

 private function getToken() {
 $url = " /> $data = array(
 "grant_type" => "client_credentials",
 "app_key" => $this->appKey );
 $ch = curl_init($url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_POSTFIELDS,  /> $response = curl_exec($ch);
 return json_decode($response, true)["access_token"];
 }
}

// 使用示例$taobaoApi = new TaobaoApi("your_app_key", "your_app_secret");
$expressFee = $taobaoApi->getExpressFee("your_item_id");
print_r($expressFee);
