python - 在网络爬虫中返回 302

Question

我模拟登录后，尝试发布原网站时返回302，在Chrome中打开原网站时返回415。

我尝试了几种方法：

session.post(url,headers = headers,data = data)

requests.post(url,headers = headers,data = data)

urllib.request.urlopen.read(url).decode()

import requets
import json
header = {'Host': 'sty.js118114.com:8080',
          'Connection': 'keep-alive',
          'Content-Length': '8188',
          'Accept': '*/*',
          'X-Requested-With': 'XMLHttpRequest',
          'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/76.0.3809.100 Safari/537.36',
          'Content-Type': 'text/plain;charset=UTF-8;application/xml',
          'Origin': 'http://sty.js118114.com:8080',
          'Referer':
'http://sty.js118114.com:8080/Report/report/movecar_list.html',
          'Accept-Encoding': 'gzip, deflate',
          'Accept-Language': 'zh-CN,zh;q=0.9',
          'Cookie': cookie_name + '=' + cookie_value
}
data = {"calling_no":"","begin_time":"","end_time":"","called_car_no":""}
res = requests.post(target,data = json.dumps(data),headers = header)
print(res.content.decode())

我希望内容必须是 json 版本或 html 版本，以便我可以使用 re model 或 xpath 来获取我想要的信息。（没有任何重定向

最后，我提供有关该问题的必要信息：
