Https方法到Https？

Question

很抱歉问了我这个问题，但是我有以下代码可以从我的web服务中获取关于我的数据库的JSON信息：

public static JSONObject readJsonFromUrl(String url) throws IOException, JSONException {
    InputStream is = new URL(url).openStream();
    try  {
        BufferedReader rd = new BufferedReader(new InputStreamReader(is, Charset.forName("UTF-8")));
        String jsonText = readAll(rd);
        return new JSONObject(jsonText);
    } finally {
        is.close();
    }
}

private static String readAll(Reader rd) throws IOException {
    StringBuilder sb = new StringBuilder();
    int cp;
    while ((cp = rd.read()) != -1) {
        sb.append((char) cp);
    }
    return sb.toString();
}

我刚刚买了一个SSL证书，我必须把我的GET方法代码从HTTP传递到HTTPS，我怎么做呢？

这是我的TLSSocketFactory来启用TLS 1.1和1.2：

public class TLSSocketFactory extends SSLSocketFactory {

private SSLSocketFactory internalSSLSocketFactory;

public TLSSocketFactory() throws KeyManagementException, NoSuchAlgorithmException {
    SSLContext context = SSLContext.getInstance("TLS");
    context.init(null, null, null);
    internalSSLSocketFactory = context.getSocketFactory();
}

@Override
public String[] getDefaultCipherSuites() {
    return internalSSLSocketFactory.getDefaultCipherSuites();
}

@Override
public String[] getSupportedCipherSuites() {
    return internalSSLSocketFactory.getSupportedCipherSuites();
}

@Override
public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
    return enableTLSOnSocket(internalSSLSocketFactory.createSocket(s, host, port, autoClose));
}

@Override
public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}

@Override
public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException, UnknownHostException {
    return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port, localHost, localPort));
}

@Override
public Socket createSocket(InetAddress host, int port) throws IOException {
    return enableTLSOnSocket(internalSSLSocketFactory.createSocket(host, port));
}

@Override
public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort) throws IOException {
    return enableTLSOnSocket(internalSSLSocketFactory.createSocket(address, port, localAddress, localPort));
}

private Socket enableTLSOnSocket(Socket socket) {
    if(socket != null && (socket instanceof SSLSocket)) {
        ((SSLSocket)socket).setEnabledProtocols(new String[] {"TLSv1.1", "TLSv1.2"});
    }
    return socket;
}
}

使用POST方法，我创建了一个TLSSocket工厂的实例，并将其应用于POST方法，如下所示：

TLSSocketFactory tlsSocketFactory = new TLSSocketFactory();
        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
        conn.setSSLSocketFactory(tlsSocketFactory);

但是我的问题是..。我怎样才能为我的GET方法做同样的事情呢？

谢谢你帮我！

若要将TLSSocketFactory设置为给定url，假设它是HTTPS，则可以使用：

HttpsURLConnection conn = (HttpsURLConnection) new URL(url).openConnection();
conn.setSSLSocketFactory(tlsSocketFactory);

正如您对POST、PUT等所做的一样，要显式地声明希望此conn使用GET

conn.setRequestMethod("GET");

或者根据需要使用"POST"或"PUT"。然后：

conn.connect();
InputStream is = conn.getInputStream();

并从InputStream中读取JSON数据。

希望这能有所帮助！
