采用HttpURLConnection方式调用第三方接口，接口的返回值经过unicode编码处理

在接口的调用过程中，第三方接口的返回值使用unicode处理了，调用过程中一直报错

改成下面这样就可以了

public class TestStatic {
public static void main(String[] args) throws Exception {
getDatas();
}
public static void getDatas(){
HttpURLConnection conn = null;
try {
String INFORMATION_URL = "http://250.250.250:8080/datasnap/rest/TInterFace/getoverdayreaderinfor";
conn = getConnection(INFORMATION_URL, "GET");
conn.setConnectTimeout(30000);
conn.setReadTimeout(30000);
conn.connect();
String resp = "";
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream(), "utf-8"));
String next = null;
while ((next = reader.readLine()) != null) {
resp += next;
}
} catch (IOException e) {
e.printStackTrace();
}
conn.disconnect();
System.out.println(resp);

} catch (Exception e) {
e.printStackTrace();
}
}
private static HttpURLConnection getConnection(String urlString,String verb) {
HttpURLConnection conn = null;
try {
URL url = new URL(urlString);
conn = (HttpURLConnection)url.openConnection();
conn.setRequestMethod(verb);
conn.setDoInput(true);
conn.setDoOutput(true);
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
}
