之前只有requests发送过get请求，误以为post请求和get请求一摸一样，果不其然开始报错，一开始报错
请求https错误,加上参数：verify=False

res = requests.post(url=self.url, data=self.params['param'], verify=False, headers=headers)

请求头错误

{"timestamp":"2021-10-19T07:05:24.562+00:00","status":415,"error":"Unsupported Media Type","message":"","path":""}

后加上请求头信息

headers = {'Content-Type': 'application/json'}

又因为是请求https服务，所以会有报错提示，但是请求成功

InsecureRequestWarning: Unverified HTTPS request is being made to host '0.0.0.0'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings

后发现是一个警告，关闭该警告：

requests.packages.urllib3.disable_warnings()

然后就是持续的400错误，才发现传输的数据竟然是个字典，将列表从字典中拿出来，json序列化一下，发送成功。

		self.params = {'param': [1,2,3]}
		requests.packages.urllib3.disable_warnings()
        headers = {'Content-Type': 'application/json'}
        body = json.dumps(self.params['param'])
        res = requests.post(url=self.url, data=body, verify=False, headers=headers)
        return res
