原来每次遇到json loads/dumps始终搞不清方向,写段代码试下:
[python] view plain copy print?
import json
dict_ = {1:2, 3:4, "55":"66"}
# test json.dumps
print type(dict_), dict_
json_str = json.dumps(dict_)
print "json.dumps(dict) return:"
print type(json_str), json_str
# test json.loads
print "\njson.loads(str) return"
dict_2 = json.loads(json_str)
print type(dict_2), dict_2
程序结果:
<type 'dict'> {'55': '66', 1: 2, 3: 4}
json.dump(dict) return:
<type 'str'> {"55": "66", "1": 2, "3": 4}
json.loads(str) return
<type 'dict'> {u'55': u'66', u'1': 2, u'3': 4}
总结:
json.dumps : dict转成str
json.loads: str转成dict
如此简单。
