Paypal 沙盒 API：javax.net.ssl.SSLHandshakeException：收到致命警报：handshake_failure

Question

在沙盒模式下使用 PayPal MassPay API 时遇到异常。

同样的代码之前工作过，现在它给了我一个SSLHandshakeException。我认为这是因为 PayPal 最新的 SSL 认证更新。有人可以帮我解决这个问题吗？

以下是我的异常日志：

http-bio-9090-exec-1，RECV TLSv1 ALERT：致命，handshake_failure

您使用的似乎是旧版本的 TLS。 PayPal 最近（几天前）对其沙箱进行了更改，要求所有连接都通过 HTTP 1.1 和 TLS 1.2 完成。尝试将您的代码设置为使用较新版本的 TLS (1.2)，看看是否有帮助。显然它对这里的很多人都有效。

Answer 2

问题是 PayPal 最近（1 月 19 日或 20 日）将沙箱切换到 TLS 1.2，不再支持 TLS 1。我猜你是在 Java SE 7 或更早版本上运行的。如果你在网上搜索一下，你会发现：

尽管 Java SE 7 版本中的 SunJSSE 支持 TLS 1.1 和 TLS 1.2，默认情况下，这两个版本都没有为客户端连接启用。一些服务器没有正确实现前向兼容性，并且 拒绝与 TLS 1.1 或 TLS 1.2 客户端通信。为了互操作性， SunJSSE 默认不为客户端启用 TLS 1.1 或 TLS 1.2 连接。

要启用 TLS 1.2，您可以使用 VM 的以下设置：-Dhttps.protocols=TLSv1.1,TLSv1.2 然后它将起作用。

如果您想查看有关握手的更多详细信息，可以使用此 VM 选项：-Djavax.net.debug=all

如果您看到以下内容，则可以确认 TLS 1.2 已禁用：

*** ClientHello, TLSv1

读取服务器响应后，将抛出异常。 Java 8 没有这个问题，因为默认启用了 TLS 1.2。

目前只有沙盒受到影响。您可以在 PayPal 的网站上阅读：

PayPal 正在更新其服务以要求所有 HTTPS 都使用 TLS v1.2 2016 年 6 月 17 日的连接。在该日期之后，所有 TLS v1.0 和 TLS v1.1 API 连接将被拒绝。

这很可能会被进一步推迟。

您可以重现问题并使用这个简单的一次性代码进行试验：

URL sandbox = new URL("https://api.sandbox.paypal.com/v1/oauth2/token");
URLConnection yc = sandbox.openConnection();

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

Answer 3

本周我一直在处理同样的问题（Paypal TLS 1.2 与 JRE 1.6）。经过疯狂的几个小时后，我设法使用 BouncyCastle 和一些我并不引以为豪的代码解决了这个问题（就像一个补丁一样。持久的解决方案将升级到 JRE 1.8）。

BouncyCastle 依赖：

<dependency>
    <groupId>org.bouncycastle</groupId>
    <artifactId>bcprov-jdk15on</artifactId>
    <version>1.54</version>
</dependency>

我的工作代码：

    StringBuilder data = new StringBuilder();
    Iterator<Entry<String, String>> paramIt = paramMap.entrySet().iterator();
    while (paramIt.hasNext()) {
        Entry<String, String> param = paramIt.next();
        data.append(param.getKey()).append("=").append(HttpUtils.encodeUTF8(param.getValue()));
        if (paramIt.hasNext()) {

        Socket socket = new Socket(java.net.InetAddress.getByName(url.getHost()), 443);
        TlsClientProtocol protocol = new TlsClientProtocol(socket.getInputStream(), socket.getOutputStream(), secureRandom);
        DefaultTlsClient client = new DefaultTlsClient() {

                TlsAuthentication auth = new TlsAuthentication() {

                    public void notifyServerCertificate(org.bouncycastle.crypto.tls.Certificate serverCertificate) throws IOException {

        protocol.connect(client);

        output2.write("Content-Type:text/plain; charset=UTF-8\r\n".getBytes("UTF-8")); // So the server will close socket immediately.
        output2.write("\r\n".getBytes("UTF-8")); // HTTP1.1 requirement: last line must be empty line.
        output2.write(data.toString().getBytes("UTF-8"));
        output2.flush();

        InputStream input2 = protocol.getInputStream();
        StringBuilder stringBuffer = new StringBuilder();
        try {
            InputStreamReader reader = new InputStreamReader(input2, "UTF-8");
            int ch;
            while ((ch = reader.read()) > -1) {
                stringBuffer.append((char) ch);
            }
            reader.close();
        } catch (Exception e) {
            // Log some messages...
        }

        Map<String, String> result = new HashMap<String, String>();
        String[] lines = stringBuffer.toString().split("\r\n");
        String paramsLine = "";
        for (int i = 0; i < lines.length; i++) {
            if (lines[i].equals("")) {
                paramsLine = lines[i + 1];
                i = lines.length;
            }
        }

        // El contenido de la respuesta vendrá después del salto de linea
        for (String param : paramsLine.split("&")) {
            String[] keyValue = param.split("=");
            result.put(keyValue[0], URLDecoder.decode(keyValue[1], "UTF-8"));
        }

        return result;
    } catch (Exception e) {
        // Log some messages....
        return null;
    }
}

}

Answer 4

如果您从 Web 服务或 JAVA 中的独立应用程序中调用 https 请求，请使用以下行使其工作：

System.setProperty(“https.protocols”, “TLSv1,TLSv1.1,TLSv1.2”);

Answer 5

我的问题是我安装了 java 7，所以我升级到 java 8，瞧，这个异常不再存在了 :)
