接口测试中某个操作依赖session 如何处理???

首先, 要知道http协议中,references字段依赖关系;

比如说,做登录操作:抓取session结果如下:

此处首页Ctrl+F5强制刷新获取到响应实体中的userSession

以代码形式获取进行参数化传递, 拿到上一个page首页面的响应中的session作为登录的条件参数进行传入即可;

直接上代码:

public String doHomePage() throws ClientProtocolException, IOException, URISyntaxException {
		// 强制刷新 http://172.31.3.161:1080/WebTours/nav.pl?in=home
		// http://172.31.3.161:1080/WebTours/nav.pl?in=home
		client = HttpClients.createDefault();
		URI uri = new URIBuilder().setScheme("http").setHost("172.31.3.161").setPort(1080).setPath("/WebTours/nav.pl")
				.setParameter("in", "home").build();

		HttpGet get = new HttpGet(uri);
		response = client.execute(get);
		httpEntity = response.getEntity();

		String result = EntityUtils.toString(httpEntity);

		// JSONObject object = JSONObject.parseObject(result);
		// System.out.println(result);

		return result;
	}

此处要从 result String类型的字段中获取到HTML中的Session字段, 我们对Html 进行解析,jsoup ;

此处为Jsoup连接地址:http://www.oschina.net/p/jsoup/?fromerr=YuZhBZHi

jsoup 是一款 Java 的HTML 解析器，可直接解析某个URL地址、HTML文本内容。它提供了一套非常省力的API，可通过DOM，CSS以及类似于JQuery的操作方法来取出和操作数据。

jsoup的主要功能如下：

    从一个URL，文件或字符串中解析HTML；

    使用DOM或CSS选择器来查找、取出数据；

    可操作HTML元素、属性、文本；

jsoup是基于MIT协议发布的，可放心使用于商业项目。

示例代码：

File input = new File("/tmp/input.html");
Document doc = Jsoup.parse(input, "UTF-8", "http://example.com/");

Element content = doc.getElementById("content");
Elements links = content.getElementsByTag("a");
for (Element link : links) {
  String linkHref = link.attr("href");
  String linkText = link.text();
}

解析代码如下:

Document parse = Jsoup.parse(html);
		// 获取body元素内容
		Document bodyFragment = Jsoup.parse(html);
		// System.out.println(bodyFragment.data());
		Elements sessionElement = parse.getElementsByAttributeValue("name", "userSession");
		String attr = sessionElement.attr("value");
		// System.out.println(attr.toString());

对登录页面用fiddler进行抓取操作,查看请求对象以及响应实体:

图中红色标记处为 Page首页面传递过来的Session值:

我们以代码形式实现传递:

此处红色标记处发现打印出来的结果与fiddler 抓取到的结果不一致,经查询是进行了转义操作 ;

    post = new HttpPost("http://172.31.3.161:1080/WebTours/login.pl");
        // HttpPost post = new
        // HttpPost("http://172.31.3.183:1080/cgi-bin/nav.pl?in=home");

        ArrayList<BasicNameValuePair> list = new ArrayList<BasicNameValuePair>();
        list.add(new BasicNameValuePair("userSession", session));
        BasicNameValuePair valuePair = new BasicNameValuePair("userSession", session);
        String value = valuePair.getValue();
        System.out.println(valuePair.getName() + "111111111111111---->" + value);
        list.add(new BasicNameValuePair("username", "jojo"));
        list.add(new BasicNameValuePair("password", "bean"));
        list.add(new BasicNameValuePair("login.x", "0"));
        list.add(new BasicNameValuePair("login.y", "0"));
        list.add(new BasicNameValuePair("login", "Login"));
        list.add(new BasicNameValuePair("JSFormSubmit", "off"));

        formEntity = new UrlEncodedFormEntity(list, Consts.UTF_8);
        post.setEntity(formEntity);
        response = client.execute(post);
        httpEntity = response.getEntity();
        String result = EntityUtils.toString(httpEntity);
        System.out.println(result);

最后 :和fiddler 进行抓取到的结果进行对比: 结果保持一致:

<!--

information.  Set the user up to make reservations...
