我一直试图让客户端通过SSL安全地与服务器通信。我创建了自己的自签名证书，看起来客户端可以使用证书连接到服务器，但客户端似乎从未从服务器获得响应。我试着打印返回-1的内容长度，实际的内容似乎是一个空字符串，尽管预计会有一个简单的HTML'hello world'。Android：问题与SSL交换消息
我在做什么错？
服务器：
public class SSLServer {
public static void main(String[] args) {
String ksName = "key.jks";
char ksPass[] = "password".toCharArray();
char ctPass[] = "password".toCharArray();
try {
KeyStore ks = KeyStore.getInstance("JKS");
ks.load(new FileInputStream(ksName), ksPass);
KeyManagerFactory kmf =
KeyManagerFactory.getInstance("SunX509");
kmf.init(ks, ctPass);
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(kmf.getKeyManagers(), null, null);
SSLServerSocketFactory ssf = sc.getServerSocketFactory();
SSLServerSocket s
= (SSLServerSocket) ssf.createServerSocket(8888);
System.out.println("Server started:");
// Listening to the port
SSLSocket c = (SSLSocket) s.accept();
BufferedWriter w = new BufferedWriter(
new OutputStreamWriter(c.getOutputStream()));
w.write("HTTP/1.0 200 OK");
w.write("Content-Type: text/html");
w.write("<html><body>Hello world!</body></html>");
w.flush();
w.close();
c.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
客户：
public class TestSSLActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Instantiate the custom HttpClient
DefaultHttpClient client = new MyHttpClient(getApplicationContext());
HttpGet get = new HttpGet("https://192.168.15.195:8888");
// Execute the GET call and obtain the response
HttpResponse getResponse;
try {
getResponse = client.execute(get);
HttpEntity responseEntity = getResponse.getEntity();
Log.i("Connection",responseEntity.getContentLength()+"");
BufferedReader reader = new BufferedReader(new InputStreamReader(responseEntity.getContent(), "UTF-8"));
StringBuilder builder = new StringBuilder();
for (String line = null; (line = reader.readLine()) != null;) {
builder.append(line).append("\n");
}
Log.i("Connection","build: "+builder.toString());
} catch (Exception e) {
Log.i("Connection",e.getMessage());
}
}
定义HTTP客户端：
public class MyHttpClient extends DefaultHttpClient {
final Context context;
public MyHttpClient(Context context) {
this.context = context;
}
@Override
protected ClientConnectionManager createClientConnectionManager() {
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
// Register for port 443 our SSLSocketFactory with our keystore
// to the ConnectionManager
registry.register(new Scheme("https", newSslSocketFactory(), 443));
return new SingleClientConnManager(getParams(), registry);
}
private SSLSocketFactory newSslSocketFactory() {
try {
// Get an instance of the Bouncy Castle KeyStore format
KeyStore trusted = KeyStore.getInstance("BKS");
// Get the raw resource, which contains the keystore with
// your trusted certificates (root and any intermediate certs)
InputStream in = context.getResources().openRawResource(R.raw.key);
try {
// Initialize the keystore with the provided trusted certificates
// Also provide the password of the keystore
trusted.load(in, "password".toCharArray());
} finally {
in.close();
}
// Pass the keystore to the SSLSocketFactory. The factory is responsible
// for the verification of the server certificate.
SSLSocketFactory sf = new SSLSocketFactory(trusted);
// Hostname verification from certificate
// http://hc.apache.org/httpcomponents-client-ga/tutorial/html/connmgmt.html#d4e506
sf.setHostnameVerifier(SSLSocketFactory.STRICT_HOSTNAME_VERIFIER);
return sf;
} catch (Exception e) {
throw new AssertionError(e);
}
}
}
