java - 我无法通过 Bitstamp 交换在 Java 上使用 Fix Protocol 创建 SSL 连接

Question

我遇到了与 Bitstamp 的安全连接问题。

我创建了新的 SSL 连接，但出现异常“无法找到请求目标的有效证书路径”。他们在白名单中设置了我的 ip 和密钥，我通过 http 连接成功地从这个交换中接收了数据。以另一种方式，我使用FixSimulator来获取和接收修复消息，因此它在他们这边正常工作。不幸的是，我无法显示 FixLibrary.getLogon 方法，因为它包含 Bitstamp Api 的密钥，但我确信它可以正常工作。我究竟做错了什么？

public static void main(String[] args) throws IOException {
        SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
        SSLSocket sslSocket = (SSLSocket) sslsocketfactory.createSocket("fix.bitstamp.net", 8905);
        sslSocket.startHandshake();

        PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(sslSocket.getOutputStream())));
        String logonText = FixLibrary.getLogon(1);
        System.out.println(logonText);
        out.print(logonText);
        out.flush();

        BufferedReader in = new BufferedReader(new InputStreamReader(sslSocket.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null) {
            System.out.println(inputLine);
        }
        in.close();
        out.close();
        sslSocket.close();
}
