我正在尝试使用pymongo模块从URL中提取一个JSON文件并将其按原样发送到mongoDB。

我有以下代码

#!/usr/bin/env python
import sys, urllib2, json, pymongo
from pymongo import MongoClient
myurl = "https://gist.githubusercontent.com/border/775526/raw/b921df18ba00262ab5bba8cadb3c178e1f7748f7/config.json"
response = urllib2.urlopen(myurl)
data = response.read()
connection = MongoClient('mongodb://user:password@localhost.com:27017/database')
connection.database_names()
db = connection.database
posts = db.posts
post_id = posts.insert_many(data).inserted_id

执行此操作后，出现此错误，引发TypeError（“ documents must be a non-empty
list”）TypeError：文档必须为非空列表

理想情况下，我希望能够从url中提取json并更新mongoDB，因为此json文件每周都会更新。谢谢
