java 将InputStream中的内容读到字节数组

Posted 2021-05-08

    BufferedInputStream in = new BufferedInputStream(resource.getInputStream()); 
      ByteArrayOutputStream out = new ByteArrayOutputStream(1024); 
      byte[] temp = new byte[1024];          
      int size = 0;          
      while ((size = in.read(temp)) != -1) {          
          out.write(temp, 0, size);          
      }          
      byte[] content = out.toByteArray()
