如何使用python将表单发布到aspx站点

Question

我试图在这个网站上用python做一个搜索查询https://www.ahpra.gov.au/Registration/Registers-of-Practitioners.aspx?m=Search

但我不知道如何更正我的代码，如下所示：

from bs4 import BeautifulSoup
import requests

s = requests.session()
url="https://www.ahpra.gov.au/Registration/Registers-of-Practitioners.aspx?m=Search"
r = s.get(url)
soup = BeautifulSoup(r.content, 'html5lib')

formdata = {
   '__VIEWSTATE': soup.find('input', attrs={'name': '__VIEWSTATE'})['value'],
    "__EVENTTARGET": "",
    "__EVENTARGUMENT": "",
    "__LASTFOCUS": "",
    "__VIEWSTATEFIELDCOUNT": "2",
    "ctl22$ctl00$ddBoards": "",
    "ctl22$ctl00$ucSearch$txtSearch": "",
    "ctl22$ucSearch$txtSearch": "",
    "ctl22$ddBoards": "",
    "content_0$contentcolumnmain_0$txtFamilyName": "Mccarthy",
    "content_0$contentcolumnmain_0$txtGivenName": "",
    "content_0$contentcolumnmain_0$txtRegistrationNumber": "",
    "content_0$contentcolumnmain_0$ddlProfession": "",
    "content_0$contentcolumnmain_0$txtSuburb": "",
    "content_0$contentcolumnmain_0$txtPostcode": "",
    "content_0$contentcolumnmain_0$ddlState": "",
    "content_0$contentcolumnmain_0$btnSearch": "Search"
}

        }
s.post(url, data=formdata,headers=headers)

我得到一个服务器错误，没有结果，所以我想我遗漏了一些东西。肯定有办法吗？你知道吗

Answer 1

我认为这个问题与你如何发送formdata有关。不要将其作为字符串发送，而要尝试将其作为JSON发送。你知道吗

尝试替换此行：

s.post(url, data=formdata,headers=headers)

用这个：

s.post(url, json=formdata,headers=headers)

希望这有帮助
