python数据类型转换

读取文件的数据默认为string，接口需要bytes

转换   

data=bytes(value,'utf8')

 定义对象

values='{"diastolic": "76", "pulse": "62", "measureWay": "2", "testTime": "2016-09-27 19:36:07", "town": "310116503000", "systolic": "103", "personCard": "4XX98XXX9010XXXXX8"}'

 查看类型

print(type(values))

 输出结果

<class 'str'>

定义对象

values={"diastolic": "76", "pulse": "62", "measureWay": "2", "testTime": "2016-09-27 19:36:07", "town": "310116503000", "systolic": "103", "personCard": "4XXXXXXXXXXXXXXXXXXXXXXX8"}

 

查看类型，输出结果

<class 'dict'>

dict转str

data=json.dumps(values)

 str转bytes

data=bytes(data,'utf8')
