python oss上传图片

1.阿里云OSS

创建用于测试的Bucket
测试的Bucket名称：test–space
读写权限根据自己需求（这里我设置的如下）

 

 

 

 

 

 

2. 获取Access Key

可以在RAM访问控制中创建一个用户赋予只是对OSS管理的权限
RAM访问控制：https://ram.console.aliyun.com/overview

3.脚本

import pymysql, requests, time
import urllib.request
import oss
from io import BytesIO
from dateutil.parser import parse

    # 请求的地址
    url1 = 'https://www.tianqi.com/wxyt/'
    result = requests.get(url1, headers=headers)
    soup = BeautifulSoup(result.text, "html.parser")
    targetCode = soup.select("#weixing_img option")
    # 循环拿选择器的数据
    for i in targetCode:

        f = urllib.request.urlopen(urls)

            # 删除重复的数据

            print("delete ok!")
            # 执行sql语句
            cursor.execute(sql_insert)
            cursor.execute(sql_del)
            conn.commit()
            # 关闭数据库连接
            conn.close()


if __name__ == '__main__':
        get_img()

oss 配置

import oss2
def img(data_str, bytes_stream):
    # id与密钥
    auth = oss2.Auth('账号', '密钥')
    # 域名(根据自己选的地区修改域名）
    endpoint = 'http://oss-cn-域名.aliyuncs.com'
    endpoint = 'http://oss-cn-shanghai.aliyuncs.com'
    # 文件名
    bucket = oss2.Bucket(auth, endpoint, '文件名')
    bucket.put_object(data_str, bytes_stream)
