概述

OSS的集成上传和下载提供了SDK可以直接使用，但实际使用中一些用户受限环境或者设备限制需要使用api方式来实现上传和下载，本文以PutObject接口为例，提供了python实现的demo。
注：建议优先使用OSS提供SDK，本文提供的只是签名实现上传demo，实际使用中需要结合业务来进行改动代码

PutObject实现Demo（测试环境python2.7）:

# -*- coding: utf-8 -*- import base64 import hmac import sha import urllib2 from datetime import datetime accesskey = '您的accesskey'; accesskeysecret = '您的AccesskeySecret' endpoint='oss-cn-hangzhou.aliyuncs.com' bucket='您的bucket名称' #您的上传文件路径 object='mytest/test.png' GMT_FORMAT = '%a, %d %b %Y %H:%M:%S GMT' time = datetime.utcnow().strftime(GMT_FORMAT) print(time) signature = hmac.new(accesskeysecret, "PUT\n\nimage/png\n"+time+"\n"+"/"+bucket+"/"+object,sha) Signature = base64.b64encode(signature.digest()) print("Signature: %s" % Signature) opener = urllib2.build_opener(urllib2.HTTPHandler) with open("/Users/wanghe/Documents/20190717101549.png") as f: data=f.read() request = urllib2.Request("http://"+bucket+"."+endpoint+"/"+object, data=data) request.add_header("Authorization", "OSS "+accesskey+":"+Signature) request.add_header("Content-Type", "image/png") request.add_header("Date", time) request.get_method = lambda:"PUT" url = opener.open(request)
