下面是本人的服务端：
@WebServlet("/user")
public class UserServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
req.setCharacterEncoding("utf-8");
Enumeration<String> e=req.getHeaderNames();
while(e.hasMoreElements()){
String key=e.nextElement();
System.out.println(key+"="+req.getHeader(key));
}
resp.setCharacterEncoding("utf-8");
resp.setContentType("text/html;charset=utf-8");
PrintWriter out=resp.getWriter();
String name=req.getParameter("name");
if("kaiqi".equals(name)){
System.out.println("通过验证");
out.println("<html><head><title></title></head><body>successed<body></html>");
}else{
System.out.println("验证未通过");
out.println("<html><head><title></title></head><body>failed<body></html>");
}
}
}
下面是本人的android客户端，只有一个按钮控件：
public class MainActivity extends AppCompatActivity {
private Button loginBtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loginBtn=(Button)findViewById(R.id.loginBtn);
loginBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new Thread(){
@Override
public void run() {
String urlStr="http://192.168.1.101:8080/AndroidNetTest/user?name=kaiqi";
//String urlStr="http://www.baidu.com";
try {
URL url=new URL(urlStr);
HttpURLConnection con= (HttpURLConnection) url.openConnection();
InputStream in=con.getInputStream();
byte[] buf=new byte[1024];
in.read(buf);
Log.i("wjq",new String(buf,"utf-8"));
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
}
});
}
}
发送get请求响应的是乱码，使用百度地址返回的响应能正确接收，是不是本人的配置有问题？

输出的时候再转一下utf-8的，sting.getbytes(“utf-8”)

问问你服务端的编码是什么，要和服务端使用的编码一样
