https

根据URL获取图片资源

public void setUserImage(String urlPath) {
try {
            Log.i(TAG, "https协议准备获取网络头像资源...");

            Bitmap bitmap = httpsGetBitmap(urlPath);
            image = (ImageView)findViewById(R.id.image);
            image.setImageBitmap(bitmap);  
        } catch (Exception e) {
            String error = "网络连接失败，请重试！";
            // Toast.makeText(MainActivity.this, error, 1).show();
            Log.e(TAG, e.toString());
        }
    }


private Bitmap httpsGetBitmap(String URLPath) throws Exception {
        URL url = new URL(URLPath);

        SSLContext sslctxt = SSLContext.getInstance("TLS");

        sslctxt.init(null, new TrustManager[] { new MyX509TrustManager() },
                new java.security.SecureRandom());

        HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();

        conn.setSSLSocketFactory(sslctxt.getSocketFactory());
        conn.setHostnameVerifier(new MyHostnameVerifier());

        conn.connect();
        InputStream inputSream = conn.getInputStream();
        Bitmap bitmap = BitmapFactory.decodeStream(inputSream);
        inputSream.close();

        conn.disconnect();

        return bitmap;
    }

还有种http，忽略https证书获取字符串的

private String getInputJson(String urlString, String userName, String token) {
        try {
            urlString = urlString + userName + "&token=" + token;
            Log.i(TAG, "发送请求链接：" + urlString);
            HttpURLConnection conn = null;
            URL url = new URL(urlString);

            // 关键代码
            // ignore https certificate validation |忽略 https 证书验证
            if (url.getProtocol().toUpperCase().equals("HTTPS")) {
                trustAllHosts();
                HttpsURLConnection https = (HttpsURLConnection) url
                        .openConnection();
                https.setHostnameVerifier(DO_NOT_VERIFY);
                conn = https;
            } else {
                conn = (HttpURLConnection) url.openConnection();
            }

            // conn = (HttpURLConnection) url.openConnection();
            conn.setDoInput(true);

            conn.setConnectTimeout(8 * 1000);
            conn.setDoOutput(true);
            conn.setRequestMethod("GET");
            conn.setRequestProperty("accept", "*/*");

            // 发送用户名参数
            // String param = userNameAndTokenString;
            // byte[] out = param.getBytes();

            // conn.getOutputStream().write(out);
            // conn.getOutputStream().flush();

            String location = conn.getRequestProperty("location");
            int resCode = conn.getResponseCode();
            conn.connect();
            InputStream stream = conn.getInputStream();
            byte[] data = new byte[102400];
            int length = stream.read(data);
            httpStr = new String(data, 0, length);
            conn.disconnect();

            Log.i(TAG, httpStr);
            stream.close();
        } catch (Exception ee) {
            Log.i(TAG, "error:" + ee.getMessage());
            httpStr = "";
        }
        return httpStr;
    }
