问题描述

我正在尝试使用jsoup登录" http://pawscas.usask之后获取信息.ca/cas-web/login ".我已经尝试了下面的内容，但似乎没有用，谢谢您的任何帮助.

I am trying to use jsoup to get information after logging into "http://pawscas.usask.ca/cas-web/login". I've tried what's below and it doesn't seem to work, any help would be appreciated, thanks.

Connection.Response res = null;
    try {
        res = Jsoup.connect("http://pawscas.usask.ca/cas-web/login")
            .data("username", "user") 
            .data("password", "pass")
            //.data("It", "some data")
            //.data("execution", "some data")
            //.data("_eventId", "submit")
            .method(Method.POST)
            .execute();
    } catch (IOException e) {
        e.printStackTrace();
    }

     //System.out.println(res.cookies());

    //This will get you cookies
    Map<String, String> loginCookies = res.cookies();

    Document doc = null;
    try {
        doc = Jsoup.connect("https://paws5.usask.ca/web/home-community#mycourses")
          .cookies(loginCookies)
          .get();
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.println(doc.toString());

推荐答案

尝试这个伙伴，基本上问题似乎是您提供的数据与请求不足够，您需要包括所有输入字段.

Try this buddy, basically the problem seems to be that the data you provided along with your request was not sufficient enough, you need to include ALL input fields.

其中两个输入是一个随机生成的数字，似乎与您的会话相关联(一个名为lt和execution的数字)，因此首先需要获取它们，然后将其与您的会话一起传递数据.

And two of the inputs are a randomly generated number which seems to be associated with your session (the one with the name lt and execution), so first you need to get them, then pass it along with your data.

Connection.Response initialResponse = null;
    try {
        // get "lt" and "execution" value
        initialResponse = = Jsoup.connect("http://pawscas.usask.ca/cas-web/login").method(Method.GET).execute();
        Document doc = initialResponse.parse();

        // get lt
        Element lt = doc.select("input[name=lt]").first();
        String ltVal = lt.attr("value");

        // get execution
        Element execution = doc.select("input[name=execution]").first();
        String executionVal = execution.attr("value");

        // get cookies
        Map<String, String> cookies = initialResponse.cookies();

        // now do the login
        res = Jsoup.connect("http://pawscas.usask.ca/cas-web/login")
            .data("username", "user") 
            .data("password", "pass")
            .data("lt", ltVal)
            .data("execution", executionVal)
            .data("_eventId", "submit")
            .cookies(cookies)
            .userAgent("Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.157 Safari/537.36")
            .method(Method.POST)
            .execute();
    } catch (IOException e) {
        e.printStackTrace();
    }

     //System.out.println(res.cookies());

    cookies.putAll(res.cookies());

    Document doc = null;
    try {
        doc = Jsoup.connect("https://paws5.usask.ca/web/home-community#mycourses")
          .cookies(cookies)
          .get();
    } catch (IOException e) {
        e.printStackTrace();
    }

    System.out.println(doc.toString());
