淘宝Python SDK优化支持Python3

淘宝开放平台的SDK,Python的 SDK 是在2012年,仅支持Python2.7 及以上,但不支持Python3;二现在是2102年了,像我这样的新手都是直接从Python3开始的

持续补充SDK能力

淘宝开放平台后台下载获取到的SDK文件,会根据应用的权限生产对应的SDK包,所以你可能获取到的是几十个或者上百个

NOTE: 如果你有其他的SDK没有在文档中找到,可以反馈给我或者提 Pull requests,大家一起扩充SDK

  • v1.0.6 fix 文档错误
  • v1.0.4 增加更多接口
  • v1.0.3 增加更多接口
  • v1.0.2 添加 Wdt QimenCloud-openapi
  • v1.0.1 适配 taobao-openapi

使用说明

import top.api
import json

app_key = 
app_secret = 
session_key = 

def trade_rates_get_request():
	req = top.api.TraderatesGetRequest()
	req.set_app_info(top.appinfo(app_key, app_secret))
	
	req.fields = "tid,oid,role,nick,result,created,rated_nick,item_title,item_price,content,reply,num_iid"
	req.rate_type = "get"
	req.role = "buyer"
	
	try:
		resp = req.getResponse(session_key)
	except Exception as e:
		print(e)


if __name__ == '__main__':
	result = trade_rates_get_request()
	print(result)

适配部分介绍

以下为了省时间,基本引用了 https://blog.csdn.net/starryhwj/article/details/103026402 补充了8 同时感谢 @ymj4023

1. Python3 int替代了long

FROM: str(long(time.time() * 1000))

TO: P_TIMESTAMP: str(int(time.time() * 1000))

2. 用items替代iteritems:

FROM: for key, value in application_parameter.iteritems():

TO: for key, value in application_parameter.items():

3. 查阅资料,发现有人说到dict methods dict.keys(), dict.items() and dict.values() return “views” instead of lists.这样就显而易见知道怎么改了:

FROM: keys = keys.sort()

TO: keys = sorted(keys)

4. 英文意思很明确,unicode对象在哈希之前必须进行编码转换,想起之前又看到过中文字符在python中是以unicode存在的,所以:

FROM: sign = hashlib.md5(parameters)).hexdigest().upper()

TO: sign = hashlib.md5(parameters.encode("utf-8")).hexdigest().upper()

5. 这是花费时间最长的一个错误。首先,直接看最后,错误在soket.py里,心凉了半截,难道这里的调用都不一样了,再网上看又是python 3.X的http模块,去百度了半天也没有发现类似的错误,只能自己硬着头皮去看模块,功夫不负有心人,其实也很简单,在类HTTPConnection的初始化函数是这样定义的:

FROM: connection = httplib.HTTPConnection(self.__domain, self.__port, False, timeout)

TO: connection = httplib.HTTPConnection(self.__domain, self.__port, timeout)

比较下参数发现,python 2比3多了一个参数,去掉即可,这个错误主要是是报错的地方和修改的地方不在一起,所以很难插出原因。

6. 官方文档是这样解释的:urllib has been split up in Python 3. The urllib.urlencode() function is now urllib.parse.urlencode(), and the urllib.urlopen() function is now urllib.request.urlopen()

FROM: url = N_REST + "?" + urllib.parse.urlencode(sys_parameters)

TO: url = N_REST + "?" + urllib.urlencode(sys_parameters)

7. 这个错误是在API调用出异常的时候暴露出来的。原因前面已经提到了,稍微查了下替代的方法:

if "error_response" in jsonobj:

if P_CODE in jsonobj["error_response"]:

8. 在if 需要使用反向时,应该是 != ,而不是使用 is not ;这个也是 PyCharm 给的建议,所以在使用时,所以简单调整下就好了

FROM: if respone.status is not 200:

TO: if response.status != 200:

以上调整之后,基本就可以正常跑起来了,基本是可以支持Python3的使用,我试过了Python3.6-3.9,都是OK的。

pypi Howto

把你的库上传到pypi 之前,主要依赖的是 setup.py,下方是对应的demo

  • 打包 python3 steup.py sdist
  • twine upload dist/*

注意: 需要先安装 setuptools twine

# /usr/bin/env python3
# -*- coding: utf-8 -*-

import setuptools
from distutils.core import setup
import codecs
import os
import sys

try:
	from setuptools import setup, find_packages
except:
	from distutils import setup

with open('README.md', 'r', encoding="utf-8") as fp:
	readme = fp.read()

VERSION = "1.0.0"
LICENSE = "MIT"

setup(
