HttpKit的get方法只返回String,沒有返回Bytes的方法,有些場景沒法使用,如今增長相關方法,但願下個版本能加入。java
直接貼源代碼:
ui
public static byte[] getBytes(String url, Map<String, String> queryParas, Map<String, String> headers) { HttpURLConnection conn = null; try { conn = getHttpConnection(buildUrlWithQueryString(url, queryParas), GET, headers); conn.connect(); return readResponseByte(conn); } catch (Exception e) { throw new RuntimeException(e); } finally { if (conn != null) { conn.disconnect(); } } } public static byte[] getBytes(String url, Map<String, String> queryParas) { return getBytes(url, queryParas, null); } public static byte[] getBytes(String url) { return getBytes(url, null, null); } private static byte[] readResponseByte(HttpURLConnection conn) { InputStream inputStream = null; ByteArrayOutputStream outStream = null; try { inputStream = conn.getInputStream(); outStream = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = 0; while ((len = inputStream.read(buffer)) != -1) { outStream.write(buffer, 0, len); outStream.flush(); } return outStream.toByteArray(); } catch (Exception e) { throw new RuntimeException(e); } finally { if (inputStream != null) { try { inputStream.close(); } catch (IOException e) { e.printStackTrace(); } } if (outStream != null) { try { outStream.close(); } catch (IOException e) { e.printStackTrace(); } } } }
