我不知道我是否发送了正确的多部分请求。我使用requests_toolbelt，但是当我查看request.prepare()进行调试时，发现我的请求只是一团糟。
记录器的输出
DEBUG: <MultipartEncoder:
{('{"content-disposition": "form-data; name=\\"data\\"", "content-type": "text/plain;charset = \\"UTF-8\\"", "content-transfer-encoding": "8bit"}', '{"session_id": "000001", "device_id": 1, "event_datetime": "2019-06-07T13:41:32.980755", "card_num": "1030203", "lpr_num": ""}'),

我手动设置了标头，以防止端点方面出现任何问题。 我
self.headers = {"content-type": "multipart/form-data;"+self.boundary}
multipart_data = MultipartEncoder(boundary=self.boundary,fields={(self.do_header, self.do),(self.data_header, self.data),(self.apikey_header, sf_key),(self.crc_header, self.crc)})
response = requests.Request('POST',sf_endpoint,headers=self.headers,data = multipart_data)
prepared = response.prepare()
这是说明中所述的内容：
