java - 登录http网站java

Question

我第一次尝试登录 http 网站，但我很难理解发送参数的正确格式。我看过其他例子，但它们似乎对我不起作用，所以我想看看是否有人可以向我解释这一点。此时我的代码似乎什么也没做，但它是......

HttpURLConnection url= (HttpURLConnection)new URL("http://www.myameego.com/index2.php?do=login").openConnection();
url.setDoOutput(true);
url.setRequestMethod("POST");
OutputStreamWriter writer = new OutputStreamWriter(url.getOutputStream());
writer.write("X-Mapping-fjhppofk=6A991610BA398B3A39F4B491D5382BB4;
PHPSESSID=kbo25e08t3qvu08l1shkq8kk94; userName=coled; pass=ed45d626b07112a8a501d9672f3b92796a6754b8d8d9cb4c617fec9774889220; clientID=129; X-Mapping-fjhppofk=DCE62FE972E1EF2F12D0060EC74C3681; PHPSESSID=ukeo21oldb5pqsntu7kl8j3b96");
writer.flush();

我下载了一个 http 嗅探器，认为我可以读取浏览器发送的内容。这就是我得到 write() 行的方式，它是由资源管理器发送的 cookie。我还查看了登录屏幕的源代码，发现靠近底部的一段代码看起来负责登录。

http://www.myameego.com/index2.php?do=login

有人可以告诉我如何连接到这个界面吗？我不明白它是如何工作的。如果有帮助的话，这是我通过浏览器手动登录的完整数据包。我从我的 http 嗅探器中得到它。

如何制作像上面那样的数据包？任何指导将不胜感激。

我查看了您发布的链接，http 嗅探器显示正在调用 POST 请求，但 cookie 行与手动浏览器请求的行不匹配。

HttpURLConnection httpConnection = (HttpURLConnection)new URL("http://www.myameego.com/index2.php?do=login").openConnection();
    httpConnection.setDoOutput(true);
    httpConnection.setRequestMethod("POST");
    httpConnection.setRequestProperty("Accept-Charset","UTF-8");
    httpConnection.setRequestProperty("User-Agent","Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0; NP06)");
    httpConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded;charset=UTF-8");
    String info = String.format("user=%s&coled=%s",URLEncoder.encode("user","UTF-8"),URLEncoder.encode("coled","UTF-8"));
    info += String.format("pass=%s&MYPASS=%s",URLEncoder.encode("pass","UTF-8"),URLEncoder.encode("MYPASS","UTF-8"));
    info += String.format("clientID=%s&129=%s",URLEncoder.encode("clientID","UTF-8"),URLEncoder.encode("129","UTF-8"));
    info += String.format("login=%s&Sign In=%s",URLEncoder.encode("login","UTF-8"),URLEncoder.encode("Sign In","UTF-8"));
    httpConnection.setRequestProperty("Cookie",info);
    OutputStream output = httpConnection.getOutputStream();
    output.write(info.getBytes("UTF-8"));
    int x;
    while((x = httpConnection.getInputStream().read()) != -1)System.out.print((char)x);

我的 cookies : user=user&coled=coledpass=pass&MYPASS=MYPASSclientID=clientID&129=129login=登录&Sign In=登录+登录

浏览器cookie:

有人知道我在这里可能缺少什么吗？

使用 Jsoup 应该像这样简单:

Connection.Response response = Jsoup.connect("http://www.myameego.com/index2.php?do=login")
        .method(Connection.Method.GET)
        .execute();

Document page = Jsoup.connect("http://www.myameego.com/index2.php?do=login")
        .data("user", "login")
        .data("pass", "password")
        .data("clientID", "123456")
        .cookies(response.cookies())
        .post();
