使用JSoup登录页面的困难 [英] Difficulties using JSoup logging into page

问题描述

使用JSoup，我在登录页面时遇到了严重困难.受到在论坛上发现的启发，我进行了各种尝试，开始认为存在一个我不知道的基本错误.

Making use of JSoup, I am experiencing severe difficulties logging into a page. I have undertaken various attempts, inspired by what I found on the forum, that I start to think that there is a fundamental mistake I am not aware of.

Connection.Response loginForm = Jsoup.connect("https://*****.*****.com/login")
    .method(Connection.Method.GET)
    .execute();

Document res = Jsoup.connect("https://*****.*****.com/login")
    //.data("appToken", "ef626867eae90b9f7bca8c861ef97abb370987da")
    .data("appToken", "RandomlyGeneratingToken, see comment above")
    .data("emailAddress", "*****@*****.***")
    .data("password", "*****")
    .userAgent("Mozilla")
    .post();

这是否与随机生成的输入.data("appToken", ???)有关，输入每次在请求站点时都会更改，因此我尤其不确定在此阶段要发布什么数据.执行.post();时发生错误"HTTP错误获取URL状态= 400".任何帮助将不胜感激-非常感谢您！

Does this have something to do with the randomly generating input .data("appToken", ???), which changes everytime the site is being requested, which makes me particularly unsure about what data to post at this stage. Error 'HTTP error fetching URL Status=400' occurs when .post(); is being executed. Any help will be highly appreciated - thank you very much, in advance!

推荐答案

几件事:

1. GET请求-像在POST请求中一样添加user agent字符串始终是一个好习惯:

1. The GET request - it's always a good practice to add the user agent string like you did at the POST request:

Connection.Response loginForm = Jsoup.connect("https://pro-labs.imdb.com/login")
        .method(Connection.Method.GET)
        .userAgent("Mozilla/5.0 (Windows NT 6.1; WOW64; rv:46.0) Gecko/20100101 Firefox/46.0")
        .execute();

随机的"appToken"-您必须从对上一个GET请求的响应中将其提取-您不能使用随机或旧值:

The random "appToken" - you must extract it from the response to the previous GET request - you cannot use random or old value:

Document doc = loginForm.parse();
Element e = doc.select("input[name=appToken]").first();
String appToken = e.attr("value");

POST请求-您必须添加服务器发送给您的会话cookie以及对GET请求的响应-

The POST request - you must add the session cookies that the server sends you with the response to the GET request -

Document res = Jsoup.connect("https://pro-labs.imdb.com/login")
    .data("appToken", appToken)
    .data("emailAddress", "*****@*****.***")
    .data("password", "*****")
    .userAgent("Mozilla")
    .cookies(loginForm.cookies())
    .post();
