java - 尝试从 SSLSocket 读取时获取 EOFException

我正在开发一个 SSL 客户端,它将向 SSL 服务器发出一个简单的请求并等待响应。 SSL 握手和写入正常,但我无法从套接字读取数据。我打开了 java.net.ssl 的调试并得到以下信息:

[..] 
main, READ: TLSv1 Change Cipher Spec, length = 1
[Raw read]: length = 5 0000: 16 03 01 00 20 ....
[Raw read]: length = 32 [..]
main, READ: TLSv1 Handshake, length = 32 Padded plaintext after DECRYPTION: len = 32
[..]
*** Finished verify_data: { 29, 1, 139, 226, 25, 1, 96, 254, 176, 51, 206, 35 }
*** %% Didn't cache non-resumable client session: [Session-1, SSL_RSA_WITH_RC4_128_MD5] [read] MD5 and SHA1 hashes: len = 16 0000: 14 00 00 0C 1D 01 8B E2 19 01 60 FE B0 33 CE 23 ..........`..3.# Padded plaintext before ENCRYPTION: len = 70 [..] a.j.y.
main, WRITE: TLSv1 Application Data, length = 70
[Raw write]: length = 75
[..]
Padded plaintext before ENCRYPTION: len = 70
[..]
main, WRITE: TLSv1 Application Data, length = 70
[Raw write]: length = 75
[..]
main, received EOFException: ignored main, called closeInternal(false) main, SEND TLSv1 ALERT: warning, description = close_notify Padded plaintext before ENCRYPTION: len = 18 [..]
ain, WRITE: TLSv1 Alert, length = 18 [Raw write]: length = 23
[..] main, called close()
main, called closeInternal(true)
main, called close()
main, called closeInternal(true)

[..] 是证书链。

这是一个代码片段:

try {
System.setProperty("javax.net.debug","all");
/*
* Set up a key manager for client authentication
* if asked by the server. Use the implementation's
* default TrustStore and secureRandom routines.
*/
SSLSocketFactory factory = null;
try {
SSLContext ctx;
KeyManagerFactory kmf;
KeyStore ks;
char[] passphrase = "importkey".toCharArray();

ctx = SSLContext.getInstance("TLS");
kmf = KeyManagerFactory.getInstance("SunX509");
ks = KeyStore.getInstance("JKS");

ks.load(new FileInputStream("keystore.jks"), passphrase);

kmf.init(ks, passphrase);
ctx.init(kmf.getKeyManagers(), null, null);

factory = ctx.getSocketFactory();
} catch (Exception e) {
throw new IOException(e.getMessage());
}

SSLSocket socket = (SSLSocket)factory.createSocket("server ip", 9999);

/*
* send http request
*
* See SSLSocketClient.java for more information about why
* there is a forced handshake here when using PrintWriters.
*/
SSLSession session = socket.getSession();

[build query]

byte[] buff = query.toWire();

out.write(buff);
out.flush();

InputStream input = socket.getInputStream();

int readBytes = -1;
int randomLength = 1024;
byte[] buffer = new byte[randomLength];
while((readBytes = input.read(buffer, 0, randomLength)) != -1) {
LOG.debug("Read: " + new String(buffer));
}
input.close();
socket.close();
} catch (Exception e) {
e.printStackTrace();
}

我可以多次写入并且没有收到任何错误,但 EOFException 发生在第一次读取时。

我是不是在套接字或 SSL 身份验证方面做错了什么?

谢谢。

最佳答案

问题出在我发送的数据包上。服务器正在获取数据包,检查其格式是否错误并断开连接。修复数据包格式解决了问题。
