我有这个方法：
public static String getReportMetadata (String reportId, String sessionId, String url) throws Exception{
Map<String, Object> jsonValues = new HashMap<String, Object>();
jsonValues.put("reportID", reportId);
jsonValues.put("sessionID", sessionId);
JSONObject json = new JSONObject(jsonValues);
DefaultHttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost(url + GET_REPORT_METADATA_ACTION);
AbstractHttpEntity entity = new ByteArrayEntity(json.toString().getBytes("UTF8"));
entity.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
post.setEntity(entity);
HttpResponse response = client.execute(post);
return getContent(response);
}
执行一个HTTP发布请求，当然我使用它运行AsyncTask从服务器获取数据。
我的问题：有人可以用一种简单的方式向我解释一下，我需要执行哪些步骤才能将此连接类型更改为安全连接（也称为使用HTTPS）。
仅从 android 的角度来看（即客户端应用程序）。
UPDATE:正如所建议的，我尝试仅更改链接并添加 https 而不是 http，但它没有返回答案。据我了解，我确实需要获取并存储自签名证书才能连接到服务器端
UPDATE2:对我有用的解决方案：
简单的 SSLSocketFactory：
public class EasySSLSocketFactory implements SocketFactory, LayeredSocketFactory {
private SSLContext sslcontext = null;
private static SSLContext createEasySSLContext() throws IOException {
try {
SSLContext context = SSLContext.getInstance("TLS");
context.init(null, new TrustManager[] { new EasyX509TrustManager(null) }, null);
return context;
} catch (Exception e) {
throw new IOException(e.getMessage());
}
}
private SSLContext getSSLContext() throws IOException {
if (this.sslcontext == null) {
this.sslcontext = createEasySSLContext();
}
return this.sslcontext;
}
/**
* @see org.apache.http.conn.scheme.SocketFactory#connectSocket(java.net.Socket, java.lang.String, int,
* java.net.InetAddress, int, org.apache.http.params.HttpParams)
*/
public Socket connectSocket(Socket sock, String host, int port, InetAddress localAddress, int localPort,
HttpParams params) throws IOException, UnknownHostException, ConnectTimeoutException {
int connTimeout = HttpConnectionParams.getConnectionTimeout(params);
int soTimeout = HttpConnectionParams.getSoTimeout(params);
InetSocketAddress remoteAddress = new InetSocketAddress(host, port);
SSLSocket sslsock = (SSLSocket) ((sock != null) ? sock : createSocket());
if ((localAddress != null) || (localPort > 0)) {
// we need to bind explicitly
if (localPort < 0) {
localPort = 0; // indicates "any"
}
InetSocketAddress isa = new InetSocketAddress(localAddress, localPort);
sslsock.bind(isa);
}
sslsock.connect(remoteAddress, connTimeout);
sslsock.setSoTimeout(soTimeout);
return sslsock;
}
/**
* @see org.apache.http.conn.scheme.SocketFactory#createSocket()
*/
public Socket createSocket() throws IOException {
return getSSLContext().getSocketFactory().createSocket();
}
/**
* @see org.apache.http.conn.scheme.SocketFactory#isSecure(java.net.Socket)
*/
public boolean isSecure(Socket socket) throws IllegalArgumentException {
return true;
}
/**
* @see org.apache.http.conn.scheme.LayeredSocketFactory#createSocket(java.net.Socket, java.lang.String, int,
* boolean)
*/
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException,
UnknownHostException {
return getSSLContext().getSocketFactory().createSocket(socket, host, port, autoClose);
}
// -------------------------------------------------------------------
// javadoc in org.apache.http.conn.scheme.SocketFactory says :
// Both Object.equals() and Object.hashCode() must be overridden
// for the correct operation of some connection managers
// -------------------------------------------------------------------
public boolean equals(Object obj) {
return ((obj != null) && obj.getClass().equals(EasySSLSocketFactory.class));
}
public int hashCode() {
return EasySSLSocketFactory.class.hashCode();
}
}
EasyX509TrustManager：
public class EasyX509TrustManager implements X509TrustManager {
private X509TrustManager standardTrustManager = null;
/**
* Constructor for EasyX509TrustManager.
*/
public EasyX509TrustManager(KeyStore keystore) throws NoSuchAlgorithmException, KeyStoreException {
super();
TrustManagerFactory factory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
factory.init(keystore);
TrustManager[] trustmanagers = factory.getTrustManagers();
if (trustmanagers.length == 0) {
throw new NoSuchAlgorithmException("no trust manager found");
}
this.standardTrustManager = (X509TrustManager) trustmanagers[0];
}
/**
* @see javax.net.ssl.X509TrustManager#checkClientTrusted(X509Certificate[],String authType)
*/
public void checkClientTrusted(X509Certificate[] certificates, String authType) throws CertificateException {
standardTrustManager.checkClientTrusted(certificates, authType);
}
/**
* @see javax.net.ssl.X509TrustManager#checkServerTrusted(X509Certificate[],String authType)
*/
public void checkServerTrusted(X509Certificate[] certificates, String authType) throws CertificateException {
if ((certificates != null) && (certificates.length == 1)) {
certificates[0].checkValidity();
} else {
standardTrustManager.checkServerTrusted(certificates, authType);
}
}
/**
* @see javax.net.ssl.X509TrustManager#getAcceptedIssuers()
*/
public X509Certificate[] getAcceptedIssuers() {
return this.standardTrustManager.getAcceptedIssuers();
}
}
我添加了这个方法：getNewHttpClient()
public static HttpClient getNewHttpClient() {
try {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
trustStore.load(null, null);
SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
HttpParams params = new BasicHttpParams();
HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
SchemeRegistry registry = new SchemeRegistry();
registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
registry.register(new Scheme("https", sf, 443));
ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);
return new DefaultHttpClient(ccm, params);
} catch (Exception e) {
return new DefaultHttpClient();
}
}
最后，对于我的代码中的每个位置：
DefaultHttpClient client = new DefaultHttpClient();
我将其替换为：
HttpClient client = getNewHttpClient();
我现在可以从服务器端接收数据，最后一个问题是：我所做的安全吗？或者它接受每个自签名证书？如果是这种情况应该采取什么措施来改变它？
任何帮助，将不胜感激。
