java - 如何让 HttpClient 返回状态码？

问题描述

我正在开发我的第一个 java 软件作为项目，使用我从大学学到的东西:'(

我正在尝试将学生使用它来获得结果的这个网站转换为软件，

抱歉，网站是法语，请使用谷歌翻译页面

网址：https ://www2.inscription.tn/ORegMx/servlet/AuthentificationEtud?ident=cin

如果你注意到有 =cin，我还没有学过 php，但是，我认为它可以做一些我不知道如何使用 java 处理 http 请求的事情，所以我这样做了，但我需要知道如何获取状态代码知道它是否是 200 所以连接成功并且输入是正确的并且用户已经连接并且如果另一个代码那么有一个错误

WebDriver driver = new HtmlUnitDriver();
driver.get("https://www4.inscription.tn/ORegMx/servlet/AuthentificationEtud");

WebElement cin = driver.findElement(By.name("cin"));
WebElement date = driver.findElement(By.name("dn"));
WebElement captcha = driver.findElement(By.name("cincap"));

String cinValue=CIN.getText();
String dateValue=daten.getText();
String captchaValue=captcha.getText();

cin.sendKeys(cinValue);
date.sendKeys(dateValue);
captcha.sendKeys(captchaValue);

captcha.submit();

网站的登录表单中也有一个验证码，所以我正在考虑使用 jTextPane 作为小浏览器窗口（仍然不知道该怎么做）来显示验证码，以便用户知道要写什么

我正在将 Eclipse 与 windowbuilder pro 一起使用

有效的http请求

解决方案

WebDriver API 不提供对 HTTP 状态的访问。在How to get HTTP Response Code using Selenium WebDriver中有一篇关于获取此信息的原因和选项的冗长帖子

您可以在提交调用后使用 WebDriver API 检查结果。在此网站上查找错误页面特有的元标记和页面元素。通过 findElement 调用，您可以确保它们存在于结果页面中。

在这种特殊情况下，服务器似乎只是再次提供相同的表单。您可以从上面重复使用您的电话。

在有效登录的结果页面中，您可以通过其类名“logout”找到注销链接。如果 webdriver 找不到该元素，则您的登录尝试失败。

    try {
      WebElement logout = driver.findElement(By.className("logout"));
    } catch (NoSuchElementException e) {
      // you are not logged in
    }
