TypeError：“NoneType”对象不可调用（Python，请求）

Question

使用一个 tax_id 运行脚本时，输出没有任何问题。但是当我添加多个 tax_id 时，会出现“TypeError: 'NoneType' object is not callable”错误消息。

import requests
from bs4 import BeautifulSoup as bs
import re

url = 'https://www.e-taxes.gov.az/controller'

tax_ids = [
        '1306142621',
        '1403676911',
         ]

request_payloads = {"METHOD": "wsEbynGetDebetSum",
                    "voen": tax_ids,
                    }

with requests.Session() as s:
    for tax_id in tax_ids:
        request_payloads['voen'] = tax_id
        r = s.post(url, params=request_payloads)
        url_t = r.url
        response = requests.get(url_t)
        s = bs(response.content, 'lxml')
        output = s.text.strip()
        debt = re.search('"debet":"(.+?)"}}', output)
        if debt:
            m = debt.group(1)
            print([tax_id] + [m])

错误信息是

Traceback (most recent call last):
  File "taxDebt.py", line 19, in <module>
    r = s.post(url, params=request_payloads)
TypeError: 'NoneType' object is not callable

Answer 1

s = bs(response.content, 'lxml')

这一行正在覆盖您在此处声明的会话变量：

with requests.Session() as s

将s = bs(...) 变量名更改为其他名称：

with requests.Session() as s:
    for tax_id in tax_ids:
        request_payloads['voen'] = tax_id
        r = s.post(url, params=request_payloads)
        url_t = r.url
        response = requests.get(url_t)
        s1 = bs(response.content, 'lxml')
        output = s1.text.strip()
        debt = re.search('"debet":"(.+?)"}}', output)
        if debt:
            m = debt.group(1)
            print([tax_id] + [m])

结果：

['1306142621', '0.00']
['1403676911', '0.00']
