当我想打开HTTPS连接时，我会收到SSL异常。如何以一种对这种异常不敏感的方式设置HttpURLConnection？

我的代码是:

private String getData() {
    String response = null;
    String connection = "https://www.kamalan.com/";

    try {
        URL url = new URL(connection);
        Log.i(TAG, "Try to open: " + connection);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();

        int responseCode = conn.getResponseCode();
        Log.i(TAG, "Response code is: " + responseCode);
        if (responseCode == HttpURLConnection.HTTP_OK) {
            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            if (in != null) {
                StringBuilder strBuilder = new StringBuilder();
                int ch = 0;
                while ((ch = in.read()) != -1)
                    strBuilder.append((char) ch);

                // get returned message and show it
                response = strBuilder.toString();
                Log.i("JSON returned by server:", response);
            }

            in.close();

        } else {
            Log.e(TAG, "Couldn't open connection in getResepiItems()");
        }
    } catch (SSLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return response;
}

最佳答案

请按照以下方法，它对我有用。

        URL url = new URL("Your URL");
        HttpsURLConnection urlConnection =(HttpsURLConnection) url.openConnection();    urlConnection.setSSLSocketFactory(SSLCertificateSocketFactory.getInsecure(0, null));
        urlConnection.setHostnameVerifier(getHostnameVerifier());
        InputStream is = urlConnection.getInputStream();
        OutputStream os = new FileOutputStream(downloadedFile);
        byte[] data = new byte[1024];
        int count;
        while ((count = is.read(data)) != -1) {
            os.write(data, 0, count);
        }
        os.flush();
        os.close();
        is.close();

下面的方法来设置主机名

private HostnameVerifier getHostnameVerifier() {
        HostnameVerifier hostnameVerifier = new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                HostnameVerifier hv =
                        HttpsURLConnection.getDefaultHostnameVerifier();
                return hv.verify("com.example.com", session);
            }
        };
        return hostnameVerifier;
    }
