如何以编程方式登录到一个网站？ [英] How to programmatically log into a website?

问题描述

我已经看过计算器上的多个例子并不能得到它的工作。

I have looked at multiple examples on stackoverflow and cannot get it to work.

这是我需要登录到programmtically的网址： http://powerschool.fortschools.org/public/

This is the url I need to log into programmtically:http://powerschool.fortschools.org/public/

我已经尝试了很多不同的方式，但我没有成功。继承人是我目前有：

I have tried many different ways but am unsuccessfully. Heres what I have currently:

原始URL在登录前： http://powerschool.fortschools.org/public/

Original Url before logging in: http://powerschool.fortschools.org/public/

在登录后网址

Url after logging in: http://powerschool.fortschools.org/guardian/home.html

表我想在登录前提交：

<form action="/guardian/home.html" method="post" name="LoginForm" target="_top" id="LoginForm" onsubmit="doPCASLogin(this);">
<input type="hidden" name="pstoken" value="308732667SkW2oaVnhxqIqM5PzqdGWrXW4jdQoB8W">
<input type="hidden" name="contextData" value="2AA011214C3F506D76216C5B459574636E2269F51AC438EB11081A7C735345A8">
<input type="hidden" name="dbpw" value="">
<input type="hidden" name="translator_username" value="">
<input type="hidden" name="translator_password" value="">
<input type="hidden" name="translator_ldappassword" value="">

<input type="hidden" name="returnUrl" value="">
<input type="hidden" name="serviceName" value="PS Parent Portal">
<input type="hidden" name="serviceTicket" value="">
<input type="hidden" name="pcasServerUrl" value="/">
<input type="hidden" name="credentialType" value="User Id and Password Credential">

<h2>Parent Sign In</h2>
<!--box content-->

<fieldset id="login-inputs" class="group">

<div id="translatorInput" style="display: none;">

  <input type="password" name="translatorpw" value="" size="39">
</div>
<div class="button-row">
  <button type="submit" id="btn-enter" title="Sign In To PowerSchool Parent Access" value="Enter" border="0">Sign In</button>
</div>
</fieldset>       
<!-- box content-->
</form>

pssing提交按钮的形式更改此（只有dbpw变化，（这是使pstoken两个不同的实例和contextData的确发生了变化））$ P $后：

After pressing the submit button the form changes to this (only the dbpw changes, (this was two seperate examples so the pstoken and the contextData did change)):

这是你完全登录后，

This is after you "fully log in"

下面是我的code（不工作）：

Here is my code (not working):

public static final String POWERSCHOOLLOGINURL = "http://powerschool.fortschools.org/public/";
    public static final String POWERSCHOOLLOGIN = "http://powerschool.fortschools.org/guardian/home.html";

    public static void main(String[] args) throws IOException {
        Map<String, String> nameToVal = new HashMap<String, String>();
        nameToVal.put("pstoken", "308732667b2uBDHKHeNJc1XTXdgDSVwxzHfzldM9M");
        nameToVal.put("contextData", "e1c94866f2ed77f3ae37bc1a2a477631");
        nameToVal.put("dbpw", "29e3fdf45f7959a5e0c894ad01b34941");
        nameToVal.put("translator_username", "");
        nameToVal.put("translator_password", "");
        nameToVal.put("translator_ldappassword", "");
        nameToVal.put("returnUrl", "");
        nameToVal.put("serviceName", "PS Parent Portal");
        nameToVal.put("serviceTicket", "");
        nameToVal.put("pcasServerUrl", "/");
        nameToVal.put("credentialType", "User Id and Password Credential");
        nameToVal.put("account", "horvste");
        nameToVal.put("translatorpw", "");
        nameToVal.put("returnUrl", "");
        nameToVal.put("pcasServerUrl", "/");
        nameToVal.put("credentialType", "User Id and Password Credential");
        Map<String, String> cookies = new HashMap<String, String>();
        cookies.put("JSESSIONID", "2C108FB2394FFE097E366BC3C34827B8");
        cookies.put("lastHref",
                "http%3A%2F%2Fpowerschool.fortschools.org%2Fguardian%2Fhome.html");
        cookies.put("uiStateCont", "null");
        cookies.put("uiStateNav", "null");

        Document doc = Jsoup.connect(POWERSCHOOLLOGIN).cookies(cookies)
                .data(nameToVal).method(Method.POST).post();
        System.out.println(doc.toString());

    }

请注意：是的HtmlUnit不是一个可以接受的答案（这是缓慢和Android上不工作）

note: HtmlUnit is not an acceptable answer (it's to slow and doesn't work on android).

推荐答案

您将不得不模拟一下md5.js（可在开发工具的资源选项卡中找到）与上提交表单做的：

You'll have to simulate what md5.js (which can be found in the resources tab of dev tools) is doing with the form on submit:

    function doPCASLogin(form) {
   var originalpw = form.pw.value;
   var b64pw = b64_md5(originalpw);
   var hmac_md5pw = hex_hmac_md5(pskey, b64pw)
   form.pw.value = hmac_md5pw;
   form.dbpw.value = hex_hmac_md5(pskey, originalpw.toLowerCase())
   if (form.ldappassword!=null) {
     // LDAP is enabled, so send the clear-text password
     // Customers should have SSL enabled if they are using LDAP
     form.ldappassword.value = originalpw; // Send the unmangled password
   }

   // Translator Login
   var translatorpw = form.translatorpw.value;
   var i = translatorpw.indexOf(";");
    if (i < 0) {
        form.translator_username.value = translatorpw;
        form.translator_password.value = "";
    }
    else {
        form.translator_username.value = translatorpw.substring(0,i);
        translatorpw = translatorpw.substring(i+1); // Get the password
        translatorpw2 = translatorpw;
        translatorpw = b64_md5(translatorpw);                   // Added in move to pcas
        form.translator_password.value = hex_hmac_md5(pskey, translatorpw);
        if (form.translator_ldappassword!=null) {
            // LDAP is enabled, so send the clear-text password
            // Customers should have SSL enabled if they are using LDAP
            form.translator_ldappassword.value = translatorpw2; // Send the pw for LDAP
        }
    }

    return true;
}
