我使用一个web服务从服务器检索数据。基本上，脚本发送一个xml来获得xml格式的响应。下面的Python脚本工作得很好。

import requests
    
    url="https://fakelink.com/myapp/WebServices/Public/ExportData.asmx"
    headers = {'content-type': 'text/xml', 'SOAPAction': 'http://mywebservice.com/ExportQueryData'} 
    body = """<?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
      <soap:Body>
        <ExportQueryData xmlns="http://mywebservice.com/">
          <company>mycompany</company>
          <user>myuser</user>
          <query>Test</query>
          <parameterList>
          </parameterList>     
        </ExportQueryData>
      </soap:Body>
    </soap:Envelope>"""
    
    response = requests.post(url,data=body,headers=headers)
    print(response.text)

Python脚本返回以下内容：

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </ExportQueryDataResponse>
    </soap:Body>
</soap:Envelope>

我需要同样的结果，但是通过js。但是我没有找到这种语言。到目前为止，我得到的是：

function soap() {

var xmlhttp = new XMLHttpRequest();
xmlhttp.open('POST', 'https://fakelink.com/myapp/WebServices/Public/ExportData.asmx', true);
var sr =
'<?xml version="1.0" encoding="utf-8"?>' +
'<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' +
'<soap:Body>' +
'<ExportQueryData xmlns="http://mywebservice.com/">' +
'<company>mycompany</company>' +
'<user>myuser</user>' +
'<query>Test</query>' +
'<parameterList>' +
'</parameterList>' +
'</ExportQueryData>' +
'</soap:Body>' +
'</soap:Envelope>';

xmlhttp.setRequestHeader('Content-Type', 'text/xml');
xmlhttp.send(sr);
alert(xmlhttp.readyState);
alert(xmlhttp.status);
alert(xmlhttp.responseText);
}

警报分别返回1、0和“"。
我可能遗漏了什么。有什么帮助吗？
