Question

我一直在尝试使用python和请求库进行soap调用，因为它在xml文件定义上非常灵活。我尝试过zeed和sud，不幸的是，在我创建实例之前，zeed不允许我定义portypes并且suds不允许我更改enconding文件，suds只是使用utf-8，然后我决定使用request library for raw soap呼叫。但是，响应始终为状态500。

我的问题是：

出了什么问题？
运行此肥皂呼叫的正确方法是什么？

响应

response.status_code 500
response.text <?xml version='1.0' ?>
<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/'>
<env:Body>
<env:Fault>
<faultcode>env:Client</faultcode>
<faultstring>Internal Error</faultstring>
</env:Fault>
</env:Body>
</env:Envelope>

import pystache
import requests
import base64
import urllib

from wsse.client.requests.auth import WSSEAuth


invoice_file_name = '10101010101-03-F004-00000001.zip'

invoice_file_path = 'path_to/10101010101-03-F004-00000001.zip'

with open(invoice_file_path, 'rb') as file:
    invoice_file_data = base64.b64encode(file.read())


xml_send_bill_path = os.path.join(
    os.path.dirname(os.path.abspath(__file__)),
    'templates',
    'send_bill.xml'
)
with open(xml_send_bill_path, 'r') as file:
    xml_send_bill = file.read()

xml_send_bill_string = pystache.render(xml_send_bill, {
    'SunatRUC': '20100066603',
    'SunatUser': 'MODDATOS',
    'SunatPass': 'moddatos',
    'InvoiceFileName': invoice_file_name,
    'InvoiceFileContent': invoice_file_data
})

WSDL_URL = 'https://e-factura.sunat.gob.pe/ol-ti-itcpfegem/billService?wsdl'
#WSDL_URL = 'https://e-beta.sunat.gob.pe/ol-ti-itcpfegem-beta/billService?wsdl';

encoded_request = xml_send_bill_string.encode('iso-8859-1')
headers = {
    'content-type': 'text/xml',
    'charset': 'iso-8859-1',
    "Content-Length": str(len(encoded_request))
}

response = requests.post(
    url=WSDL_URL,
    data=encoded_request,
    headers=headers,
    auth = WSSEAuth('20100066603MODDATOS', 'moddatos')
)

print ("response.status_code", response.status_code)
print ("response.text", response.text)

请求lib的Python SOAP调用没有按预期工作
