WebSocket客户端关闭连接
WebSocket客户端关闭连接
提问于 2019-10-10 16:42:21
我正试图在Java中构建一个独立的WebSocket客户机，该客户机连接到C#中的WebSocket服务器。我正在使用为WebSocket服务器生成的自签名证书。我能够连接到WebSocket服务器在我的Chrome浏览器使用WSS，没有任何问题。尝试使用TooTallNate/Java-WebSocket库时，它不起作用。在连接时立即调用OnClose方法。
生成的*.pfx文件中有一个自签名证书，用于C#服务器，并导入到受信任的根存储区。我使用keytool从这个文件中创建了一个*.jks (我认为我做的是正确的)。我正在使用keystore.jks，它是由我的代码中的keytool生成的。
以下是我的主要方法：
public static void main(String[] args) throws Exception {
ChatClient chatclient = new ChatClient("wss://thomas.localnetwork.com:65120/wsserver?userId=Thomas", "Thomas", "1", "1", "L");
// load up the key store
String STORETYPE = "JKS";
String KEYSTORE = "C:\\Users\\thomas\\Desktop\\keystore.jks";
String STOREPASSWORD = "test12345";
String KEYPASSWORD = "test";
KeyStore ks = KeyStore.getInstance( STORETYPE );
File kf = new File( KEYSTORE );
ks.load( new FileInputStream( kf ), STOREPASSWORD.toCharArray() );
KeyManagerFactory kmf = KeyManagerFactory.getInstance( "SunX509" );
kmf.init( ks, KEYPASSWORD.toCharArray() );
TrustManagerFactory tmf = TrustManagerFactory.getInstance( "SunX509" );
tmf.init( ks );
SSLContext sslContext = null;
sslContext = SSLContext.getInstance( "TLS" );
sslContext.init( kmf.getKeyManagers(), tmf.getTrustManagers(), null );
// sslContext.init( null, null, null ); // will use java's default key and trust store which is sufficient unless you deal with self-signed certificates
SSLSocketFactory factory = sslContext.getSocketFactory();// (SSLSocketFactory) SSLSocketFactory.getDefault();
chatclient.setSocketFactory( factory );
chatclient.connectBlocking();
BufferedReader reader = new BufferedReader( new InputStreamReader( System.in ) );
while ( true ) {
String line = reader.readLine();
if( line.equals( "close" ) ) {
chatclient.closeBlocking();
} else if ( line.equals( "open" ) ) {
chatclient.reconnect();
} else {
ucm.send( line );
}
}
}以下是我收到的例外情况：

... 3 more有没有办法让我了解更多关于握手的细节或者实际问题是什么？异常堆栈跟踪似乎毫无帮助。

我的问题是我的本地防火墙引起了问题。我还发现可以将证书安装到Java的可信根存储区。
请注意，每个Java版本(JDK和JRE)都有自己的“仙人掌”文件。确保为您的开发或运行时环境安装到正确的。我的头撞在墙上，因为它在IntelliJ工作，直到我意识到这一点。
- 将证书安装到JVM受信任的根存储区。
- 检查它是否已正确安装
- 删除代码的keystore部分
下面是在将证书安装到正确位置后对我的代码的更改。
public static void main(String[] args) throws Exception {
ChatClient chatclient = new ChatClient("wss://thomas.localnetwork.com:65120/wsserver?userId=Thomas", "Thomas", "1", "1", "L");
chatclient.connectBlocking();
BufferedReader reader = new BufferedReader( new InputStreamReader( System.in ) );
while ( true ) {
String line = reader.readLine();
if( line.equals( "close" ) ) {
chatclient.closeBlocking();
} else if ( line.equals( "open" ) ) {
chatclient.reconnect();
} else {
chatclient.send( line );
}
}
