如何从学校主页获取经过身份验证的数据? [英] How can I fetch authenticated data from school homepage?
问题描述
我想从大学主页检索经过身份验证的数据，并且没有API调用.
I want to crawl my authenticated data from university homepage and there are no API calls.
因此，我必须将ID和密码之类的POST数据发送到服务器，但是如果不单击登录按钮就无法登录.
Therefore, I have to send POST data like id and password to server, but I cannot login without clicking login button.
下面是我的大学主页代码.
Below is my code of university homepage.
<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" >-->

</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，此实现仅填写表格，而不单击登录按钮.在这种情况下，我想将数据发送到服务器.我该怎么办?
However, this implementation only fills the form and not click the login button. In this situation, I wanna send my data to server. How can I do that?
推荐答案
我相信这是您查看信息的方式.
I believe here is how you grok the info.
步骤1，导航到登录页面. 第2步，打开浏览器调试工具，然后选择网络
Step 1, navigate to login page. Step 2, open your browser debugging tools and select network
第3步，登录失败或成功获取帖子信息
Step 3, fail or succeed the login to grab the post info
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，创建您的登录名
With all of that information, create your login
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，我不理解所有这些字段的含义或尝试成功，因此无论我是否应该发送int或字符串，我都无法进行验证.最坏的情况是，您需要使用网络浏览器
I honestly do no understand what all these fields mean or have a successful attempt, so I cannot verify regardless whether I am supposed to send an int or string. The worst case scenario, you need to use a webbrowser
