[英]How to do Website Authentication in Java Applet?
I have a wireless IP camera and I want to make my own web page to show its live stream. 我有一个无线IP摄像机,我想创建自己的网页以显示其实时流。 The address of the stream is "http://192.168.1.2:8082/index.cgi"
(supposed) and it requires User authentication. 流的地址是"http://192.168.1.2:8082/index.cgi"
(假定),它需要用户验证。 This means that when we enter the above URL in browser it asks for username and password. 这意味着,当我们在浏览器中输入上述URL时,它会要求输入用户名和密码。
All what I want is that to make a java applet, on loading the java applet, it should authenticate the URL and show the image/stream. 我想要的是制作一个Java小程序,在加载Java小程序时,它应该验证URL并显示图像/流。

Q: How to do Http authentication in Java applet? 问:如何在Java applet中进行Http身份验证?
I shall be thankful for every answer. 我会很感激每一个答案。
You can achieve it by making an HttpURLConnection and appending username and password with the URL. 您可以通过建立HttpURLConnection并将URL添加用户名和密码来实现。 As: 如:
URL myURL = new URL("http://192.168.1.2:8082/index.cgi?username=user&password=");
HttpURLConnection myConnection = (HttpURLConnection) myURL.openConnection();
myConnection.setDoOutput(false);
int status = ((HttpURLConnection) myConnection).getResponseCode();
Alternatively (instead of appending username/password to url), you can try( not sure if it is allowed in Applet) setting the default authenticator for http requests like this: 另外,您也可以尝试(不确定在Applet中是否允许)为HTTP请求设置默认的身份验证器(而不是在URL中附加用户名/密码):
Authenticator.setDefault (new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication ("username", "password".toCharArray());
}
});
You can also use Apache HttpComponents HttpClient which is very easy to use. 您还可以使用非常易于使用的Apache HttpComponents HttpClient 。 To know more about how HTTP requests work in Java, see this answer . 要了解有关HTTP请求在Java中如何工作的更多信息,请参见此答案 。
