当我尝试进行一些报废时，我在python上遇到以下错误：
追踪（最近一次呼叫最后一次）：
文件“”，第26行，in signin2.fields [“ctl06 $ txtParam_1”]。value ='139210'
文件“C：\ Users \ Alvaro Pabon \ Anaconda3 \ lib \ site-packages \ werkzeug \ datastructures.py“，行 781，在 getitem 引发exceptions.BadRequestKeyError（key）
BadRequestKeyError：400错误请求：浏览器（或代理）发送了一个 请求此服务器无法理解。
我提供了html和python代码，我做错了什么？

使用python请求库
创建Json并将其传递给标题并记住＆lt; __ EVENTTARGET＆gt; ＆LT; __ EVENTARGUMENT＆GT;此前＆lt;＆gt;提示参数总是在几分钟后改变（基于网站）。
如果您使用POST方法并且在发送请求之前检查它在POSTMAN中一次会很容易。
header = {
"ctl00$ContentPlaceHolder1$txt_tradename": str(index),
"ctl00$ContentPlaceHolder1$txtSearchTin": "",
"ctl00$ContentPlaceHolder1$ddl_dist": 2,
"ctl00$ContentPlaceHolder1$btnDlrSearch": "Search",
"__EVENTVALIDATION": token.get("__EVENTVALIDATION", "")
, "__VIEWSTATEGENERATOR": token.get("__VIEWSTATEGENERATOR"),
"__VIEWSTATE": token.get("__VIEWSTATE")
}
try:
req = requests.post(url, header)
