我已经使用POST请求在python中创建了一个脚本,以从网页中获取不同供应商的名称,但是不幸的是,我遇到了这个错误AttributeError: 'NoneType' object has no attribute 'text',但是我发现我以正确的方式做了事情

要填充内容,必须单击搜索按钮,就像在图像中看到的那样。

到目前为止,我已经尝试过:

import requests
from bs4 import BeautifulSoup

url = "https://www.gebiz.gov.sg/ptn/supplier/directory/index.xhtml"

r = requests.get(url)
soup = BeautifulSoup(r.text,"lxml")

payload = {
    'contentForm': 'contentForm',
    'contentForm:j_idt225_listButton2_HIDDEN-INPUT': '',
    'contentForm:j_idt161_inputText': '',
    'contentForm:j_idt164_SEARCH': '',
    'contentForm:j_idt167_selectManyMenu_SEARCH-INPUT': '',
    'contentForm:j_idt167_selectManyMenu-HIDDEN-INPUT': '',
    'contentForm:j_idt167_selectManyMenu-HIDDEN-ACTION-INPUT': '',
    'contentForm:search': 'Search',
    'contentForm:j_idt185_select': 'SUPPLIER_NAME',
    'javax.faces.ViewState': soup.select_one('[id="javax.faces.ViewState"]')['value']
}

res = requests.post(url,data=payload,headers={
    'Content-Type': 'application/x-www-form-urlencoded',
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36'
    })
sauce = BeautifulSoup(res.text,"lxml")
item = sauce.select_one(".form2_ROW").text
print(item)
  

仅此部分也可以: 8121 results found.

完整追溯:

Traceback (most recent call last):
  File "C:\Users\WCS\AppData\Local\Programs\Python\Python37-32\general_demo.py", line 27, in <module>
    item = sauce.select_one(".form2_ROW").text
AttributeError: 'NoneType' object has no attribute 'text'

您需要找到一种获取cookie的方法。当前,在多个请求中,以下内容对我有用。
