# 处理响应数据
jsonContent = json.dumps(str(response.content, encoding = 'utf-8'))
rspResult = jsonContent.encode('utf-8').decode('unicode-escape')
py_json = demjson.decode(rspResult)

最后一句出错 demjson.JSONDecodeError: Unexpected text after end of JSON value
rspResult的值为：
"{"status":"200","message":"操作成功","sign":"2bdc69a2b64daab10a5b9b80a4425e7b","data":{"id":"0e585a17-5935-4646-9556-103861254465","name":"大唐呼伦贝尔化肥有限公司","format_name":"大唐呼伦贝尔化肥有限公司","econKind":"有限责任公司（非自然人投资或控股的法人独资）(1153)","econKindCode":"1153","registCapi":"54820 万人民币","currency_unit":"CNY","type_new":"01","historyNames":[],"address":"内蒙古自治区呼伦贝尔经济技术开发区（谢尔塔拉）和谐路29号","regNo":"152100000000033","scope":"许可经营项目：无 一般经营项目：生产、销售合成氨、尿素、工业氧、工业氮、工业硫磺","termStart":"2007-09-04","termEnd":"2027-09-03","belongOrg":"呼伦贝尔市市场监督管理局","operName":"邓永斌","title":"法定代表人","startDate":"2007-09-04","endDate":"-","checkDate":"2022-09-05","status":"存续","new_status":"存续","orgNo":"664092139","creditNo":"911507006640921395","districtCode":"150700","actualCapi":"54820 万人民币","categoryNew":"0115601","domain":"C2600","tags":[],"revoke_reason":"-","logout_reason":"-","revoke_date":"-","fenname":"-"}}"
rspResult值前后有两个双引号，手工去掉就可以了，请问各位大神是什么原因啊。

可能是dumps()把byte转化为了str, 所以无法decode.

收到，已验证成功，谢谢！
