Selenium Webdriver :验证httpResponse xml

Question

我想验证从httpResponse获得的XML响应。

我的代码

 HttpClient httpclient = new DefaultHttpClient();
 HttpPost httpPost = new HttpPost(decouplingURL);
 httpPost.setEntity(new StringEntity(soapRequest));
 System.out.println(soapRequest);
 HttpResponse httpResponse = httpclient.execute(httpPost);
 System.out.println(httpResponse);
 String resp = EntityUtils.toString(httpResponse.getEntity(),"UTF-8");
 System.out.println(resp);
 String payload = "";
 NodeList nl = doc.getElementsByTagName("payload");
 for (int i = 0; i < nl.getLength(); i++) {
     if (nl.item(i).getNodeType() == org.w3c.dom.Node.ELEMENT_NODE) {
         org.w3c.dom.Element nameElement = (org.w3c.dom.Element) nl.item(i);
         payload = nameElement.getFirstChild().getNodeValue().trim();
     }
 }

在上面的代码中，我得到了以下响应，我想要获取@status并验证它的值是否为1。类似地，我必须验证weaher 'charge-method‘是否为3

<?xml version='1.0' encoding='UTF-8'?>
<er-response>
  <payload>
      <subscription id="33517965" status="1">
        <pricepoint id="package:aceklpackage">
          <charge-method>3</charge-method>
          <rate resource="EUR" tax-rate="0.23">30.0</rate>
          <user-group>hover32</user-group>
        </pricepoint>
      </subscription>
  </payload>
</<er-response>

Answer 1

不确定这个问题与Apache有什么关系，您正在使用Apache HttpClient。您可以简单地使用XPath从xml中提取所需的元素：

DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();

Document doc = builder.parse(new ByteArrayInputStream(resp.getBytes("UTF-8")));

XPath xPath = XPathFactory.newInstance().newXPath();

System.out.printf("Status: %s\n", xPath.evaluate("//subscription/@status", doc));
System.out.printf("Charge Method: %s\n", xPath.evaluate("//charge-method//text()", doc));

结果：

Status: 1
Charge Method: 3
