post - 如何从学校主页获取经过身份验证的数据？

问题描述

我想从大学主页爬取经过身份验证的数据，并且没有 API 调用。

因此，我必须将 ID 和密码等 POST 数据发送到服务器，但如果不单击登录按钮，我将无法登录。

以下是我的大学主页代码。

<form action="./_login.php" method="post"  autocomplete = "off" onSubmit="return comp()" name="login"  >
                <!--<form action="https://hisnet.handong.edu/login/_login.php" method="post"  autocomplete = "off" onSubmit="return comp()" name="login"  >-->
                    <!-- E-mail¿¡ ÀÖ´Â ¸µÅ©¸¦ Ŭ¸¯ÇÏ¿© À̵¿ÇÏ´Â °æ¿ì, ÀúÀåµÇ´Â °ª 3°¡Áö -->

                            <td><img src="/2012_images/intro/logbox3.gif" /></td>
                        </tr>
                        <tr>

                        </tr>
                        <tr>
                            <td><img src="/2012_images/intro/line_txt1_1.gif" border=0/><a href="/registration/regist_step1.php"><img src="/2012_images/intro/line_txt1_2.gif" border=0/></a></td>

                        <tr>
                            <td><img src="/2012_images/intro/line_txt2_1.gif" border=0/><a href="javascript:findID();"><img src="/2012_images/intro/line_txt2_2.gif"  border=0/></a></td>
                        </tr>
                        <tr>
                            <td><img src="/2012_images/intro/line_txt3_1.gif" border=0/><a href="javascript:findPW();"><img src="/2012_images/intro/line_txt3_2.gif"  border=0/></a></td>
                        </tr>
                    </table>
                </form>

我是这样实现的。

main() async {

  http.post('http://hisnet.handong.edu/login/login.php',
  headers: {'Content-Type': 'application/x-www-form-urlencoded'},
  body: {'id':'myID','password':'myPassword'})
  .then((response){
    print('Response status: ${response.statusCode}');
    print('Response body: ${response.body}');
  });
}

但是，此实现仅填写表单而不单击登录按钮。在这种情况下，我想将我的数据发送到服务器。我怎样才能做到这一点？

解决方案

我相信这就是您获取信息的方式。

第一步，导航到登录页面。第二步，打开浏览器调试工具，选择网络

图 1

第三步，登录失败或成功获取帖子信息

在此处输入图像描述

URL: https://hisnet.handong.edu/login/_login.php
POST data:

part
f_name
agree
Language=Korean
id=sadasd
password=asdasd
x=25
y=26

curl 'https://hisnet.handong.edu/login/_login.php' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:65.0) Gecko/20100101 Firefox/65.0' -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8' -H 'Accept-Language: en-US,en;q=0.5' --compressed -H 'Referer: https://hisnet.handong.edu/login/login.php' -H 'Content-Type: application/x-www-form-urlencoded' -H 'DNT: 1' -H 'Connection: keep-alive' -H 'Cookie: PHPSESSID=vn4f2mksuv4lfo1i7co2c0e184; NSC_xfcqpsubm_WJQ=ffffffffc8f47f3e45525d5f4f58455e445a4a423660; NSC_ijtofu_ttm=ffffffffc8f47f2145525d5f4f58455e445a4a423660' -H 'Upgrade-Insecure-Requests: 1' --data 'part=&f_name=&agree=&Language=Korean&id=sadasd&password=asdasd&x=25&y=26'

使用所有这些信息，创建您的登录

http.post(https://hisnet.handong.edu/login/_login.php, body: { "part" : null, "f_name" : null, "agree" : null, "Language": "Korean", "id": "sadasd", "password":"asdasd", "x": "25", "y":"26"})

老实说，我不明白所有这些字段的含义或尝试是否成功，因此无论我应该发送 int 还是 string，我都无法验证。最坏的情况，您需要使用网络浏览器
