从 v5.0.0 版本开始,我们对 SDK 的内容进行了精简。所有管理操作,比如:创建/删除 bucket、为 bucket 绑定域名、设置数据处理的样式分隔符、新增数据处理样式等都去除了,统一建议到七牛开发者平台来完成。另外,此前服务端还有自己独有的上传 API,现在也推荐统一成基于客户端上传的工作方式。

此 Python SDK 适用于 2.7 和 3.3及以上版本

安装

直接安装:

pip install qiniu

easy_install qiniu源码安装:

#从Python SDK 下载地址下载源码
tar xvzf python-sdk-$VERSION.tar.gz
cd python-sdk-$VERSION
python setup.py install

初始化

在使用SDK 前,您需要一对有效的 AccessKey 和 SecretKey 签名授权。

可以通过如下步骤获得:

点击注册开通七牛开发者帐号

如果已有账号,直接登录七牛开发者后台,点击这里查看 Access Key 和 Secret Key

获取Access Key 和 Secret Key 后,调用如下两行代码进行初始化对接:

from qiniu import Auth
q = Auth(access_key, secret_key)

上传流程

为了尽可能地改善终端用户的上传体验,七牛云存储首创了客户端直传功能。更多信息请参阅业务流程。

上传代码:

# -*- coding: utf-8 -*-
# flake8: noqa
from qiniu import Auth, put_file, etag
import qiniu.config
#需要填写你的 Access Key 和 Secret Key
access_key = 'Access_Key'
secret_key = 'Secret_Key'
#构建鉴权对象
q = Auth(access_key, secret_key)
#要上传的空间
bucket_name = 'Bucket_Name'
#上传后保存的文件名
key = 'my-python-logo.png'
#生成上传 Token,可以指定过期时间等
token = q.upload_token(bucket_name, key, 3600)
#要上传文件的本地路径
localfile = './sync/bbb.jpg'
ret, info = put_file(token, key, localfile)
print(info)
assert ret['key'] == key
assert ret['hash'] == etag(localfile)
上传&回调
# -*- coding: utf-8 -*-
# flake8: noqa
from qiniu import Auth, put_file, etag
import qiniu.config
access_key = 'Access_Key'
secret_key = 'Secret_Key'
q = Auth(access_key, secret_key)
bucket_name = 'Bucket_Name'
key = 'my-python-logo.png'
#上传文件到存储后, 存储服务将文件名和文件大小回调给业务服务器。
policy={
'callbackUrl':'http://your.domain.com/callback.php',
'callbackBody':'filename=$(fname)&filesize=$(fsize)'
}
token = q.upload_token(bucket_name, key, 3600, policy)
localfile = './sync/bbb.jpg'
ret, info = put_file(token, key, localfile)
print(info)
assert ret['key'] == key
assert ret['hash'] == etag(localfile)

上传&预转持续化

以视频转码为例:

# -*- coding: utf-8 -*-
# flake8: noqa
from qiniu import Auth, put_file, etag, urlsafe_base64_encode
import qiniu.config
access_key = 'Access_Key'
secret_key = 'Secret_Key'
q = Auth(access_key, secret_key)
bucket_name = 'Bucket_Name'
key = 'my-python-logo.png'
#设置转码参数
fops = 'avthumb/mp4/s/640x360/vb/1.25m'
#转码是使用的队列名称
pipeline = 'abc'
#可以对转码后的文件进行使用saveas参数自定义命名,当然也可以不指定文件会默认命名并保存在当前空间
saveas_key = urlsafe_base64_encode('目标Bucket_Name:自定义文件key')
fops = fops+'|saveas/'+saveas_key
#在上传策略中指定
policy={
'persistentOps':fops,
'persistentPipeline':pipeline
}
token = q.upload_token(bucket_name, key, 3600, policy)
localfile = './sync/bbb.jpg'
ret, info = put_file(token, key, localfile)
print(info)
assert ret['key'] == key
assert ret['hash'] == etag(localfile)

队列pipeline 请参阅创建私有队列;转码操作 具体参数请参阅音视频转码;saveas 请参阅处理结果另存。

Tips:上面的Demo只是针对视频转码功能,如果您需要使用比如音视频切片、视频截图、视频拼接等功能只需要修改上面 fops 后面的参数即可,如:fops = vframe/jpg/offset/1/w/480/h/360/rotate/90 就表示视频截图了。

可以看到上传成功后的行为主要是由上传凭证中的 上传策略 来指定。其中 上传策略 可以指定的行为不止这些,具体请参阅 上传策略 。

生成上传token

# -*- coding: utf-8 -*-
# flake8: noqa
from qiniu import Auth
#需要填写你的 Access Key 和 Secret Key
access_key = ''
secret_key = ''
#构建鉴权对象
q = Auth(access_key, secret_key)
#要上传的空间
bucket_name = ''
#上传后保存的文件名
key = ''
#生成上传 Token,可以指定过期时间等
# 上传策略示例
# https://developer.qiniu.com/kodo/manual/1206/put-policy
policy = {
# 'callbackUrl':'https://requestb.in/1c7q2d31',
# 'callbackBody':'filename=$(fname)&filesize=$(fsize)'
# 'persistentOps':'imageView2/1/w/200/h/200'
}
#3600为token过期时间,秒为单位。3600等于一小时
token = q.upload_token(bucket_name, key, 3600, policy)
print(token)
# 数据处理
- 触发持久化操作
## 触发持久化操作

以视频转码为例:

python
# -*- coding: utf-8 -*-
# flake8: noqa
from qiniu import Auth, PersistentFop, build_op, op_save, urlsafe_base64_encode
#对已经上传到存储的视频发起异步转码操作
access_key = 'Access_Key'
secret_key = 'Secret_Key'
q = Auth(access_key, secret_key)
#要转码的文件所在的空间和文件名。
bucket = 'Bucket_Name'
key = '1.mp4'
#转码是使用的队列名称。
pipeline = 'mpsdemo'
#要进行转码的转码操作。
fops = 'avthumb/mp4/s/640x360/vb/1.25m'
#可以对转码后的文件进行使用saveas参数自定义命名,当然也可以不指定文件会默认命名并保存在当前空间
saveas_key = urlsafe_base64_encode('目标Bucket_Name:自定义文件key')
fops = fops+'|saveas/'+saveas_key
pfop = PersistentFop(q, bucket, pipeline)
ops = []
ops.append(fops)
ret, info = pfop.execute(key, ops, 1)
print(info)
assert ret['persistentId'] is not None

Tips:上面的Demo只是针对视频转码功能,如果您需要使用比如音视频切片、视频截图、视频拼接等功能只需要修改上面 fops 后面的参数即可,如:fops = vframe/jpg/offset/1/w/480/h/360/rotate/90 就表示视频截图了。

但这个只是将转码这个耗时的操作提交到队列中,要想知道转码操作现在的状态, 需要根据返回的 persitentId 进行查询,查询接口。如果您不方便持续轮询每个异步处理的进度和状态,七牛可以异步处理完成后通知您们的业务服务器。这样就需要您在视频转码的例子中,初始化 PersistentFop 时添加上 notifyUrl , 来通知您们的业务服务器。
