使用POST请求发送XML

Question

I'm newer in python. I'm trying to send to send a xml file using HTTP POST request with a body and i received this error:

```    

b'\r\nxmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" >xmlns:xsd="http://www.w3.org/2001/XMLSchema">\r\n \r\n >1\r\n XMLSyntaxE ```

我使用了Python 3.7。
这是我的密码：

import http.client
import base64
import urllib.request
import urllib.response
import urllib.parse
import urllib.error
    file = 'sendInvoices.xml'
    headers = {
        # Request headers
        'aade-user-id': 'stergos73',
        'Ocp-Apim-Subscription-Key': 'c3d8fbf2eb984942a20f9b181139fc4c',
    }
    
    params = urllib.parse.urlencode({
    })
    
    try:
        conn = http.client.HTTPSConnection('mydata-dev.azure-api.net')
        conn.request("POST", "/SendIncomeClassification?%s" % params, file, headers)
        response = conn.getresponse()
        data = response.read()
        print(data)
        conn.close()
    except Exception as e:
        print("[Errno {0}] {1}".format(e.errno, e.strerror))`enter code here`

这里是我的xml文件：
