python 淘宝OPEN API 调用示例

官方的淘宝SDK是python2，而且调用经常出问题，于是根据算法，自行封装了个。
可以支持大部分API

import time
import urllib
import hashlib
import urllib.parse
import urllib.request

# 这里填写你申请到的APPkey
app_key = 'xxxxxx'
appSecret = 'xxxxxx'

#排序
def ksort(d):
    return [(k, d[k]) for k in sorted(d.keys())]

#MD5加密
def md5(s, raw_output=False):
    """Calculates the md5 hash of a given string"""
    res = hashlib.md5(s.encode())
    if raw_output:
        return res.digest()
    return res.hexdigest()

#计算sign
def createSign(paramArr):
    sign = appSecret
    paramArr = ksort(paramArr)
    paramArr = dict(paramArr)
    for k, v in paramArr.items():
        if k != '' and v != '':
            sign += k + v
    sign += appSecret
    sign = md5(sign).upper()
    return sign

#参数排序
def createStrParam(paramArr):
    strParam = ''
    for k, v in paramArr.items():
        if k != '' and v != '':
            strParam += k + '=' + urllib.parse.quote_plus(v) + '&'
    return strParam

#高效API调用示例
def gxapi(item_id, adzone_id, site_id, session):
    # 请求参数，根据API文档修改
    postparm = {'item_id': item_id,
                'adzone_id': adzone_id,
                'site_id': site_id,
                'session': session,
                'method': 'taobao.tbk.privilege.get'
                }
    # 公共参数，一般不需要修改
    paramArr = {'app_key': app_key,
                'v': '2.0',
                'sign_method': 'md5',
                'format': 'json',
                'timestamp': time.strftime('%Y-%m-%d %H:%M:%S')
                }

    paramArr = {**paramArr, **postparm}

    sign = createSign(paramArr)
    strParam = createStrParam(paramArr)
    strParam += 'sign=' + sign
    url = 'http://gw.api.taobao.com/router/rest?' + strParam
    res = urllib.request.urlopen(url).read()
    return res


# mm_17398164_8812194_29632544
if __name__ == '__main__':
    res = gxapi('570075443473', '29632544', '8812194',                '70000100c0744973c591154b784bb59595d15bc7706a104738d1f13c665d8348dae655b82248874')
    print(res)
