我正在制作一个登录应用程序来从代码中出现的链接中检索一些信息。我的问题是我在日志文件中收到“400 错误请求。您的浏览器发送了此服务器无法理解的请求。[...] 服务器位于 idp.tut.fi 端口 443”。

此外，该链接处理带有 SHA1 的 RC4_128 用于身份验证和 RSA 用于密钥交换，但我真的不知道我可以在我的代码中在哪里应用这些协议。

谢谢你的帮助！

这是我的代码：

public class POPLogin extends Activity {

private EditText usr, pass;
private Button submitButton;
private CharSequence notify;
private String res, resp;
private final String link = "https://idp.tut.fi/idp/Authn/UserPassword";
private URL url;

public static boolean isNetworkAvailable(Context context) {
    return ((ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo() != null;
}

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_poplogin);
    usr = ((EditText) findViewById(R.id.usernameField));            
    pass = ((EditText) findViewById(R.id.passwordField));           
    submitButton = (Button) findViewById(R.id.submitButton);        
    submitButton.getBackground().setColorFilter(new LightingColorFilter(0x00FFB90F, 0xFFAA0000));   

    /*
     * This method controls the login button so that the correct
     * information is sent to the server.
     */
    submitButton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            if(isNetworkAvailable(getApplicationContext())) {   // If there is an Internet connection available

                /*
                * A new thread is created from the main one 
                * to separate the login process (AsyncTask, https operations).
                */
                new Thread(new Runnable() {
                    public void run() {
                        try {
                            url = new URL(link);
                            HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

                            // Create the SSL Connection
                            SSLContext sc;
                            sc = SSLContext.getInstance("TLS");
                            sc.init(null, null, new java.security.SecureRandom());
                            conn.setSSLSocketFactory(sc.getSocketFactory());

                            // SSL Authentication
                            String userpass = usr.getText().toString() + ":" + pass.getText().toString();
                            String basicAuth = "Basic " + Base64.encodeToString(userpass.getBytes(), Base64.DEFAULT);
                            conn.setRequestProperty("Authorization", basicAuth);

                            Log.i("NOTIFICATION", "All SSL parameters set");

                            // Set timeout and method
                            conn.setReadTimeout(7000);
                            conn.setConnectTimeout(7000);
                            conn.setRequestMethod("POST");
                            conn.setDoInput(true);          // Flag indicating this connection is used for output (POST)
                            conn.connect();

                            Log.i("NOTIFICATION", "Connection request sent");

                            // Check HTTP Response Code
                            int status = conn.getResponseCode();
                            InputStream is;
                            if (status >= 400 ) {
                                is = conn.getErrorStream();
                            } else {

                            Log.i("NOTIFICATION", "HTTP Code Checked");

                            // Receives the answer

                                resp += res;
                            }

                        } catch (Exception e) {
                            e.printStackTrace();
                        }

如果您收到 HTTP 错误代码，则证明您的 HTTPS 和 SSL 设置工作正常。

问题出在您发送的数据中。看起来您需要使用 java.net.Authenticator 而不是尝试手动操作。
