java inputstream 乱码

 

URL url=new URL(uri);

//URLConnection conn=url.openConnection();

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

//conn.setDefaultRequestProperty("Content-Type", "text/html;charset=utf-8");

 

InputStream ins=conn.getInputStream();

BufferedInputStream   bs=new   BufferedInputStream(ins); 

BufferedReader   ir=new   BufferedReader(   new   InputStreamReader(bs)); 

System.out.println(ir.readLine());

 

或者文件

File file=new File("F:\\information\\phus-goagent-084ab00\\local\\aa.txt");

InputStream ins;

try {

ins = new FileInputStream(file);

BufferedInputStream   bs=new   BufferedInputStream(ins); 

BufferedReader   ir=new   BufferedReader(   new   InputStreamReader(bs)); 

int temp=-1;

char []b=new char[1];

String str="";

while((temp=ir.read(b,0,b.length))!=-1){

str+=String.valueOf(b);

}

System.out.println(str);
