js 调用wsdl

// 创建一个新的XMLHttpRequest对象
var xhr = new XMLHttpRequest();
xhr.open('POST', 'http://example.com/service?wsdl', true);

// 设置请求头
xhr.setRequestHeader('Content-Type', 'text/xml; charset=utf-8');
xhr.setRequestHeader('SOAPAction', 'http://example.com/service/OperationName');

// 创建SOAP请求消息
var soapRequest = 
  '<?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>' +
      '<OperationName xmlns="http://example.com/service">' +
        '<param1>value1</param1>' +
        '<param2>value2</param2>' +
      '</OperationName>' +
    '</soap:Body>' +
  '</soap:Envelope>';

// 发送SOAP请求
xhr.send(soapRequest);

// 处理响应
xhr.onreadystatechange = function () {
  if (xhr.readyState === 4 && xhr.status === 200) {
    console.log(xhr.responseText);
  }
};
