烧瓶+；Pythonywhere上的Cloudinary上载错误 大家好

请帮帮我，我遇到了cloudinary上传错误。 问题是，在localhost上，这个函数工作得很好，但在pythonanywhere服务器上部署后就不行了。 使用：

• • 蟒蛇3.4
    • sqlite数据库
      • SQL炼金术1.1.4
    • 烧瓶0.11.1
    • cloudinary python模块
    • 谷歌地图模块
    • httplib2模块
    • 请求模块

我的代码：

from flask import Flask, render_template, request, redirect, url_for, \
    flash, jsonify, make_response
from flask import session as login_session  # to avoid confusion with DB session
import random
import string
import httplib2
import json

# Cloudinary API imports

import cloudinary
import cloudinary.uploader
from cloudinary.uploader import upload
import cloudinary.api
from cloudinary.utils import cloudinary_url


CLOUDINARY = {
  'cloud_name': 'ainsolence',
  'api_key': 'xxxxxxxxxxxxxxxxxxx',
  'api_secret': 'xxxxxxxxxxxxxxxxxxxxxxx',
}

cloudinary.config(cloud_name='ainsolence', api_key='xxxxxxxxxxxxxxxxxxxx',
                  api_secret='xxxxxxxxxxxxxxxxxxxxxxx')
