javascript和Web服务WSDL

Question

我想使用javascript调用网络服务。 我有一个表格，其中我给出了一些参数（整数），并且想要获得结果，如何使用JavaScript做到这一点？

这是WSDL文件

Answer 1

1. 创建一个SOAP请求并调用调用者。 参考： 最简单的SOAP示例

2. 获取响应并解析XML。 参考： 使用JavaScript解析XML

Answer 2

这是一种可能的方法，假设您将wsdl放入文件request.wsdl并假定远程服务器是可访问的并且具有Access-Control-Allow-Origin: *标头

//wsdl request
var client = new XMLHttpRequest();
client.open('GET', 'request.wsdl');
client.onreadystatechange = function () {
  var request = client.responseText;//here the wsdl

        //SOAP request
        var client2 = new XMLHttpRequest();
        client2.open('POST', 'http://83.212.96.238:8080/DgesvSampleWs/DgesvSampleWsService', true);

        client2.onreadystatechange = function () {
          if (client2.readyState == 4) {
            if (client2.status == 200) {
              console.log(client.responseText);//here the response
            }
          }
        }
        client2.setRequestHeader('Content-Type', 'text/xml');
        client2.send(request);
}

client.send();

这个想法是执行和ajax调用wsdl定义，并在其回调中执行另一个要调用的ajax。 这个域名http://83.212.96.238:808它没有给我答复，但我认为该方法有效。
