TypeError: the JSON object must be str, not 'bytes'报错问题解决

def basic_information_new_customer(url,jobMonthlyIncome,occupation,applyTime,age,personalAddress,jobCompanyAddress):
    #规则集调用
    url = url+"/api/invokeRule"
    data = {
        "sysCode": "urule_india",
        "frontTransNo": "id00011",
        "frontTransTime": "2019-05-29 00:00:00",
        "rulePackage": "PERSONAL_INFO",
        "requestBody":{
            "PersonalInfoDTO": {
                "jobMonthlyIncome": jobMonthlyIncome,#个人信息-月工资
                "occupation": occupation,#个人信息-职业
                "applyTime": applyTime,#个人信息-申请时间
                "age": age,#基本信息-年龄
                "personalAddress": personalAddress,#个人信息-申请人居住省份/邦
                "jobCompanyAddress": jobCompanyAddress#个人信息-申请人工作省份/邦
            }
        }
    }
    headers = {"Content-Type": "application/json"}
    req = requests.post(url=url, data=json.dumps(data), headers=headers)
    res = json.loads(req.content.decode())  #.decode()
    #print(type(res)) #loads 输出的是 dict类型
    return res

解决方法：

直接添加decode（）解决

decode() 方法以 encoding 指定的编码格式解码字符串。该方法返回解码后即为字符串。

decode()方法语法：str.decode(encoding='UTF-8',errors='strict')
