Python json.loads 报错：ValueError: Invalid control character at:

# coding:utf-8
import json

# 't' (tab), 'n', 'r' and ''.
data = """{"a":"a","b":1,"c":"","e":"a"}"""
print "loads strict:{}".format(json.loads(data, strict=False))
print "loafs strict default:"
print json.loads(data)

字符串中存在控制字符 't' (tab), 'n', 'r' and ''.

loads 时需要加strict=Flase.
