1.String to InputStream
String str = "String与InputStream相互转换";
InputStream in_nocode = new ByteArrayInputStream(str.getBytes()); InputStream in_withcode = new ByteArrayInputStream(str.getBytes("UTF-8"));
2.InputStream to String
这里提供几个方法。
方法1:
public String convertStreamToString(InputStream is) { BufferedReader reader = new BufferedReader(new InputStreamReader(is)); StringBuilder sb = new StringBuilder(); String line = null; try { while ((line = reader.readLine()) != null) { sb.append(line + "/n"); } } catch (IOException e) { e.printStackTrace(); } finally { try { is.close(); } catch (IOException e) { e.printStackTrace(); } } return sb.toString(); }
方法2:
public String inputStream2String (InputStream in) throws IOException { StringBuffer out = new StringBuffer(); byte[] b = new byte[4096]; for (int n; (n = in.read(b)) != -1;) { out.append(new String(b, 0, n)); } return out.toString(); }
方法3:
public static String inputStream2String(InputStream is) throws IOException{ ByteArrayOutputStream baos = new ByteArrayOutputStream(); int i=-1; while((i=is.read())!=-1){ baos.write(i); } return baos.toString(); }
