无法使用客户端的证书将请求从客户端发送到服务器，也无法使用 Python 进行 SOAP API 调用

问：

我正在尝试发送请求并尝试在客户端和服务器之间建立连接。我将证书转换为 .pem 文件，并将 .pem 文件中的私钥保存到另一个以 -----BEGIN PRIVATE KEY----- ... -----END PRIVATE KEY-----开头的文件中，并将其保存为.key文件。然后，我将证书文件的私钥添加到服务器证书.pem文件中。我以为通过在客户端和服务器之间建立这种连接。我得到了 200 个，但我没有得到任何回应。请帮忙

    import json
    import requests
    clientCrt = "path to client certificate\\ce.crt"
    certificate_secret = "path to client's private key\\pkey.key"
    url = "api_end_point_url"
    certServer = "path to server certificate\\serv.pem"
    headers = {'Content-Type': 'text/xml; charset=utf-8'}
    payload = """<?xml version="1.0" encoding="UTF-8" standalone="no"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:ns="...">
   <soap:Header/>
<soap:Body>
<ns:OrigXARequest>
<Request>
.....
</Request>
</ns:OrigXARequest>
</soap:Body>
</soap:Envelope>"""

    response = requests.get(url, data=payload, verify = certServer,
                        headers=headers, cert=(clientCrt,certificate_secret))
    print(response.status_code)
    print(response.content)
    print(response.text)`

输出

200
    b'<?xml version = "1.0" encoding = "UTF-8"?><soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soap:Body><soap:Fault xsi:type="soap:Fault"><faultcode>RTL-API-1002</faultcode><faultstring>Error occurred while invoking the ..
