一、背景

客户反馈随机上传小文件至cos速度比较慢，用Python来进行测试上传速度。

二、代码

# _auth:kaliarch
# use cos-python-sdk-v5
# https://cloud.tencent.com/document/product/436/12269

region = 'ap-chengdu'     # 替换为用户的 Region                 # 使用临时密钥需要传入 Token，默认为空，可不填
scheme = 'https'            # 指定使用 http/https 协议来访问 COS，默认为 https，可不填
bucket_name = 'xuel-test-bucket-1253961596'        #制定bucket地址
config = CosConfig(Region=region, Secret_id=secret_id, Secret_key=secret_key,  Scheme=scheme)
# 2. 获取客户端对象

            Key=content,
        )

if __name__ == '__main__':
    upload_cos(1000)

三、测试

测试500个随机文件

测试1000个随机文件
