django之使用七牛云、百度智能云、FastDFS上传文件（对象存储）

一、3个平台

1. 七牛云：https://www.qiniu.com/
2. 百度智能云：https://cloud.baidu.com/
3. FastDFS：https://www.cnblogs.com/loveprogramme/p/12901787.html（需要在自己的服务器上配置）

三、上传代码简要封装（函数）

　　 1、七牛云

from qiniu import Auth, put_data, etag
import qiniu.config


def upload(bucket_name="images-home", key=None, data=None):
    # 填写accecc_key和secret_key
    # 换成自己的AK、SK
    AK = "*"
    SK = "*"

    # 构建健全对象
    q = Auth(AK, SK)

    # 要上传的空间
    # 换成自己的bucket
    # bucket_name = "images-home"

    # 上传后保存到文件名
    # key = "*.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_data(token, key, data)
    print(ret, info)
    # ret : {'hash': 'FqoxknG28t8pQLIX4JfqDYP53Ffx', 'key': 'dj_2.jpg'}
    # info: _ResponseInfo__response:<Response [200]>, exception:None, status_code:200, text_body:{"hash":"FqoxknG28t8pQLIX4JfqDYP53Ffx","key":"dj_2.jpg"}, req_id:qhkAAAAZ9f4hwRAW, x_log:X-Log
    if info.status_code == 200:
　　　　　# 返回访问文件的地址
        return "http://qamsij369.bkt.clouddn.com/" + ret.get("key")
    else:
        raise Exception("文件上传失败")


if __name__ == '__main__':
    filename = "dj_2.jpg"
    try:
        with open(filename, "rb") as fp:
            data = fp.read()
            access_url = upload(key=filename, data=data)
    except Exception as e:
        print(e)
    else:
        print(access_url)

　　 2、百度智能云

from baidubce.bce_client_configuration import BceClientConfiguration
from baidubce.auth.bce_credentials import BceCredentials
from baidubce.services.bos.bos_client import BosClient


def upload(key, data, bucket_name="image-home"):
    #设置BosClient的Host，Access Key ID和Secret Access Key
    bos_host = "bj.bcebos.com"
    access_key_id = "*"
    secret_access_key = "*"

    #创建BceClientConfiguration
    config = BceClientConfiguration(credentials=BceCredentials(access_key_id, secret_access_key), endpoint=bos_host)

    # 创建上传客户端
    client = BosClient(config)

    response = client.put_object_from_string(bucket=bucket_name, key=key, data=data)

    access_url = "http://" + bucket_name + "." + bos_host + "/" + key

    return access_url


if __name__ == '__main__':
    filename = "dj_2.jpg"
    try:
        with open(filename, "rb") as fp:
            data = fp.read()
            access_url = upload(key=filename, data=data)
    except Exception as e:
        print(e)
    else:
        print(access_url)

　　 3、FastDFS

def upload(buffer, file_ext_name, conf="utils/fastdfs/client.conf")
    from fdfs_client.client import Fdfs_client
    from dj32_test.settings.dev import FDFS_DOMAIN
    try:
        client = Fdfs_client(conf)
    except Exception as e:
        print("配置文件错误：", e)

    response = client.upload_by_buffer(buffer, file_ext_name)
    if "successed" in response.get("Status"):
        # FDFS_DOMAIn:你的fdfs文件存储访问域名
        return FDFS_DOMAIN + response.get("Remote file_id")
    else:
        raise Exception("文件上传失败")


if __name__ == '__main__':
    filename = "dj_2.jpg"
    try:
        with open(filename, "rb") as fp:
            data = fp.read()
            ext = filename.split(".")[-1]
            access_url = upload(data, file_ext_name=ext)
    except Exception as e:
        print(e)
    else:
        print(access_url)
