app = Flask(__name__)


@app.route('/upload', methods=['GET', 'POST'])

        file = request.files['file']
        print(file.filename)
        basepath = os.path.dirname(__file__)  # 当前文件所在路径

        # 加密文件名
        file_name = md5(file.filename) + ".jpg"

        upload_path = os.path.join(basepath, 'static/', secure_filename(file_name)) # 储存路径
        print(upload_path)
        file.save(upload_path) # 保存文件

        dict_data = {"message": "上传成功"}

        return jsonify(dict_data)



def md5(string):

    ctime = str(time.time())
    m = hashlib.md5(bytes(string, encoding="utf-8"))
    m.update(bytes(ctime, encoding="utf-8"))
    return m.hexdigest()
