返回的是gbk还是utf-8或者是其他编码？你应看response返回的头文件中charset到底是什么编码然后再转换
其他几个编码方式，我都试过，打印结果都是乱码。然后我又尝试：获取字符串网页的编码方式我看了是UTF-8，当时我将myeclipse的文件系统的编码方式都改成UTF-8，代码中的转化编码也改成utf-8,结果也是乱码。然后我又按照这个思路将其他几种编码方式全部试了一遍，结果都是乱码。能具体的跟我说一下怎么改，万分感谢~
@小调~: InputStreamReader isr=new InputStreamReader(is,"gbk"); 把gbk改成utf-8就正常。我测试是这样的，不是搞java的。
URL url=new URL("http://www.baidu.com"); URLConnection urlc=url.openConnection(); InputStream is1=urlc.getInputStream(); InputStreamReader inputStreamReader = new InputStreamReader(is1,"utf-8"); BufferedReader reader = new BufferedReader(inputStreamReader); String tempLine = null; StringBuffer resultBuffer = new StringBuffer(); while ((tempLine = reader.readLine()) != null) { resultBuffer.append(tempLine); } System.out.println(resultBuffer); OutputStream os=new FileOutputStream("E:\\io2.txt"); OutputStreamWriter osr=new OutputStreamWriter(os,"gb2312"); osr.write(resultBuffer.toString());
上面是测试的，所有资源没有close
@孤零落叶寒:
URL url=new URL("http://www.baidu.com"); URLConnection urlc=url.openConnection(); InputStream is1=urlc.getInputStream(); InputStreamReader isr1=new InputStreamReader(is1,"utf-8"); BufferedReader bfr1=new BufferedReader(isr1); String data1=bfr1.readLine(); StringBuffer buffer1=new StringBuffer(); buffer1.append(data1); System.out.println(buffer1); OutputStream os=new FileOutputStream("C:\\Users\\qinghuang\\Desktop\\io2.txt"); OutputStreamWriter osr=new OutputStreamWriter(os,"gb2312"); BufferedWriter bfw=new BufferedWriter(osr); bfw.write(data1);
按照你的思路我改了一下代码，试了还是不好使啊，还是乱码~，然后我把你给的代码我在我电脑上eclipse和myeclipse都试了，打印的也是乱码~好纠结啊，难受香菇。
