pip install qiniu

q= Auth(Access Key,Secret Key)
bukect_name= '存储空间的名字'
filename = filestoreage.filename
token = q.upload_token(bukect_name,filename,3600)

ret,info = put_data(token, filename, filestorage.read())

if info.status_code==200:
url =xxx

定义的方法.py

def upload_qiniu(filestorage):
    access_key = 'KXfx2ZiBP311HkZZ8l8JHCmqlqPTJCK2sraiheVU'
    secret_key = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

    # 构建鉴权对象
    q = Auth(access_key, secret_key)

    # 要上传的空间
    bucket_name = 'liu0330'

    # 设置 上传之后保存文件的名字
    filename = 'qiniu_' + filestorage.filename

    # 生成上传 Token，可以指定过期时间等
    token = q.upload_token(bucket_name, filename, 3600)

    # put_file()
    ret, info = put_data(token, filename, filestorage.read())
    print(ret, info)

    if info.status_code == 200:
        url = Config.QINIU_DOMAIN + filename
        return url
    return None
