问题描述：


# coding=utf-8
import requests

url = "https://xxx:443/v1/sec/policy"
data = {
                ('device', '1'), ('vpn_user', '0'), (
                'sign', 'xxx'), (
                  'mid', 'xxx'), ('timestamp', '2021-10-28T10:21:37+08:00'), (
                  'app_name', 'xxx'), ('timezone', 'Asia/Shanghai'), ('format', 'JSON'), (
                  'campaign', 'default'), ('sign_version', '2.0.0'), ('sign_method', 'SHA256'), (
                  'appver', '2.0.3.1020'), ('lang', 'zh-hans'), ('version', '20201105'), (

                  'lang_region', 'zh-CN'), ('region', 'CN')

}
response = requests.post(url=url, data=data)
print(response.text)

TypeError: memoryview: a bytes-like object is required, not 'str'

这该怎么改额

答

关键点：元组转字典

data = dict(data)

response = requests.post(url=url, data=data)
print(response.text)

或者

data = dict(data)

response = requests.post(url=url, json=data)
print(response.text)

答

data = {
'login_email': login_email,
'login_password': login_password
}

答

data = json.dumps(dict(data))
response = requests.post(url=url, data=data)
print(response.text)

或者

response = requests.post(url=url, data=json.dumps(dict(data)))
print(response.text)
