如何将字符串转换为BSON?

我有一个像这样的字符串:

document = '{ time : 14/09/19 16:00:00,
   global : { full:190 , defects: 7 , btp: 6 , total: 202 } ,
   domains : [ { domain : "A" , full:7 , defects: 2 , btp: 0 , total: 9 },
               { domain : "B" , full:0 , defects: 0 , btp: 0 , total: 0 },
               { domain : "C" , full:6 , defects: 0 , btp: 0 , total: 6 },
               { domain : "D" , full:26 , defects: 0 , btp: 2 , total: 28 },
               { domain : "E" , full:0 , defects: 0 , btp: 0 , total: 0 },
               { domain : "F" , full:4 , defects: 0 , btp: 2 , total: 6 },
               { domain : "G" , full:0 , defects: 0 , btp: 0 , total: 0 },
               { domain : "H" , full:21 , defects: 0 , btp: 1 , total: 22 },
               { domain : "I" , full:32 , defects: 0 , btp: 0 , total: 32 },
               ] }'

当我尝试将其插入mongoDB集合时,我收到以下错误:

TypeError: ‘str’ object does not support item assignment

我对如何将字符串转换为BSON无能为力,以便用它来执行插入.

我查看了bson_util模块,但没有运气.

这不重要的不是BSON部分. MongoDB驱动程序将负责这一点.您的工作是将JSON转换为有效的python数据结构:

import json

data = json.loads(document)

collection.insert(data);
