python 中json和字符串互相转换
string =" {
“status”: “error”,
“messages”: [“Could not find resource or operation ‘BZK1.MapServer’ on the system.”],
“code”: 404

}"

print ‘对象：’ string

string转json对象 loads()

print ‘取值：’ json.loads(string)[‘code’]

输出结果为：

对象：{u’status’: u’error’, u’code’: 404, u’messages’: [u"Could not find resource or operation ‘BZK1.MapServer’ on the system."]}

取值：404

将对象转成字符串：dumps()

resultJson = {“state”: 1}
print json.dumps(resultJson)
