flask与七牛云上传图片

1. 认识七牛云

七牛云相当是一个网上存储空间，可以直接在浏览器里访问存储的图片。
根据CDN分发给不同的网络节点，浏览器就近取材，拿到图片，渲染页面
当然，在七牛云存储的图片也需要存储到本地一份。

2. 安装七牛云

在终端输入

pip install qiniu

安装即可

3. 使用七牛云

为七牛云创建一个独有的文件，去使用它，对于自己在七牛云官网上拿到的ak，sk等信息，要进行封装加密处理

from flask import current_app
from qiniu import Auth,put_file


class  QiniuTool():
    def __init__(self):
        ak = current_app.config.get("QINIU_AK")
        sk = current_app.config.get("QINIU_SK")
        self.q = Auth(ak,sk)
        self.bucket_name = current_app.config.get("QINIU_BUCKET_NAME")
    def upload(self,loacfilepath,newfilename):
        token = self.q.upload_token(self.bucket_name,newfilename,3600)
        print(token)
        res = put_file(token,newfilename,loacfilepath,version="v2")
        print(res)
        if res[0]["key"] == newfilename:
            return newfilename
        else:
            return False
if __name__ == '__main__':
    from app import app
    with app.app_context():
        QiniuTool().upload("./../static/exo.jpg","static/img/exo.jpg")

封站内容,调用时直接根据自己的文件路径导入

class SecretConfig():
    QINIU_AK = "Ae95CnxjK5lryTj-Fb1Z_4sLWba_7XShIrvZBQoN"
    QINIU_SK = "j5smR9D8hrf5DC2PnXD1XamwYWLyUJ1OdvaOPH9m"
    QINIU_BUCKET_NAME = "p7uploadimg"
    QINIU_URL = "http://rfluoehnd.hn-bkt.clouddn.com/"

4.flask与七牛云上传图片

上传图片需要先上传到本地在根据本地上传到七牛云

class UploadView(Resource):
    @login
    def post(self):
        img = request.files.get("img")
        ext = img.filename.split(".")[-1]
        now_time = datetime.strftime(datetime.now(),"%Y%m%d%H%M%S")
        r = str(random.randint(100000,999999))
        new_name = "%s%s.%s"%(now_time,r,ext)
        save_path = "static/%s"%new_name
        print(new_name)
        img.save(save_path)

        res = QiniuTool().upload(save_path,save_path)
        if not res:
            return jsonify({
    
                "code": 400,
                "msg": "文件上传失败"
            })
        user_info = UserModel.query.get(g.uid)
        user_info.img = save_path
        db.session.commit()
        return jsonify({
    
            "code": 200,
            "msg": "上传成功",
            "data": {
    
                "key":res
            }
        })
