要使用API接口實(shí)現(xiàn)淘寶商品上下架監(jiān)控,需遵循以下技術(shù)方案:
一、核心API接口選擇
- 商品狀態(tài)查詢接口(推薦taobao.item.get) 接口功能:獲取單個(gè)商品詳細(xì)信息(含上下架狀態(tài)) 必選參數(shù):num_iid(商品ID)、fields(需包含approve_status字段) 響應(yīng)字段:item.approve_status(ENUM值:onsale/instock)
- 批量商品查詢接口(推薦taobao.items.inventory.get.tmall) 接口功能:獲取賣(mài)家倉(cāng)庫(kù)商品列表 過(guò)濾參數(shù):banner=for_shelved(查詢所有未上架商品) 響應(yīng)字段:items.item.approve_status
二、認(rèn)證授權(quán)流程
python
# 簽名生成示例(MD5算法)
def generate_sign(params, app_secret):
sorted_params = sorted(params.items())
sign_str = app_secret + ''.join([f"{k}{v}" for k, v in sorted_params]) + app_secret
return hashlib.md5(sign_str.encode('utf-8')).hexdigest().upper()
# OAuth2.0獲取AccessToken(簡(jiǎn)化版)
def get_access_token(app_key, app_secret):
url = "https://oauth.taobao.com/token"
params = {
"grant_type": "client_credentials",
"client_id": app_key,
"client_secret": app_secret
}
response = requests.post(url, data=params)
return response.json().get('access_token')
三、監(jiān)控邏輯實(shí)現(xiàn)
python
class ItemMonitor:
def __init__(self, app_key, app_secret):
self.app_key = app_key
self.app_secret = app_secret
self.access_token = get_access_token(app_key, app_secret)
self.last_states = {}
def check_item_status(self, item_id):
# 調(diào)用商品詳情接口
url = "https://eco.taobao.com/router/rest"
params = {
"method": "taobao.item.get",
"app_key": self.app_key,
"timestamp": datetime.now().strftime("%Y-%m-%d %H:%M:%S"),
"v": "2.0",
"format": "json",
"num_iid": item_id,
"fields": "num_iid,title,approve_status"
}
params['sign'] = generate_sign(params, self.app_secret)
response = requests.get(url, params=params)
# 解析響應(yīng)
if response.status_code == 200:
data = response.json()
current_status = data.get('taobao_item_get_response', {}).get('item', {}).get('approve_status')
return current_status
return None
def monitor_loop(self, item_id, interval=300):
while True:
current_status = self.check_item_status(item_id)
last_status = self.last_states.get(item_id)
if current_status != last_status:
self.last_states[item_id] = current_status
self.send_notification(item_id, current_status)
time.sleep(interval)
def send_notification(self, item_id, status):
# 實(shí)現(xiàn)通知邏輯(郵件/短信/企業(yè)微信等)
print(f"商品{item_id}狀態(tài)變更:{status}")
四、部署與運(yùn)維
- 服務(wù)器部署 css 體驗(yàn)AI代碼助手 代碼解讀復(fù)制代碼bash # 安裝依賴 pip install requests top # 啟動(dòng)監(jiān)控(示例) python monitor.py --app_key=your_key --app_secret=your_secret --item_id=123456
- 定時(shí)任務(wù)配置(Linux Cron) bash 體驗(yàn)AI代碼助手 代碼解讀復(fù)制代碼bash # 每5分鐘檢查一次 */5 * * * * /usr/bin/python3 /path/to/monitor.py >> /var/log/taobao_monitor.log 2>&1
五、高級(jí)功能擴(kuò)展
- 批量監(jiān)控實(shí)現(xiàn) ruby 體驗(yàn)AI代碼助手 代碼解讀復(fù)制代碼python def batch_monitor(self, item_ids): for item_id in item_ids: threading.Thread(target=self.monitor_loop, args=(item_id, 300)).start()
- 狀態(tài)持久化存儲(chǔ) python 體驗(yàn)AI代碼助手 代碼解讀復(fù)制代碼python def save_state(self): with open("status.json", "w") as f: json.dump(self.last_states, f) def load_state(self): if os.path.exists("status.json"): with open("status.json", "r") as f: self.last_states = json.load(f)
六、注意事項(xiàng)
- 調(diào)用頻率限制:淘寶API對(duì)未認(rèn)證應(yīng)用限制10次/秒,認(rèn)證后提升至50次/秒
- 錯(cuò)誤重試機(jī)制: python 體驗(yàn)AI代碼助手 代碼解讀復(fù)制代碼python def safe_request(func): def wrapper(*args, **kwargs): for _ in range(3): try: return func(*args, **kwargs) except (requests.ConnectionError, requests.Timeout): time.sleep(2) continue except Exception as e: logging.error(f"請(qǐng)求失敗: {str(e)}") break return None return wrapper
該方案通過(guò)定時(shí)調(diào)用商品狀態(tài)接口,結(jié)合狀態(tài)持久化存儲(chǔ)和差異檢測(cè),可實(shí)現(xiàn)高效的商品上下架監(jiān)控。實(shí)際部署時(shí)建議結(jié)合企業(yè)微信/釘釘機(jī)器人實(shí)現(xiàn)實(shí)時(shí)告警,并配置數(shù)據(jù)庫(kù)存儲(chǔ)狀態(tài)變更歷史。
