json - Http GET 方法到 Https？

Question

抱歉我的菜鸟问题，但我有这段代码可以从我的网络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();
}

我刚买了一个 SSL 证书，我必须将我的 GET 方法代码从 HTTP 传递到 HTTPS，我该怎么做？

这是我的 TLSSocketFactory，用于启用 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;
}
}

使用我的 POST 方法，我创建了一个 TLSSocket 工厂的实例，并像这样应用于我的 POST 方法:

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

但是，我的问题是.. 我怎样才能对我的 GET 方法做同样的事情？

谢谢你帮助我!

要设置您的 TLSSocketFactory 以便在给定您的 url 的情况下使用，假设它是一个 HTTPS URL，您可以使用:

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

就像您对 POST、PUT、等 所做的一样。要明确声明您希望此 conn 使用 GET:

conn.setRequestMethod("GET");

或 “POST” 或 “PUT” 根据需要。然后:

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

并从 InputStream 中读取您的 JSON 数据。

希望这对您有所帮助!
