java用qq號(hào)獲取頭像和昵稱

在Java中,獲取QQ號(hào)對(duì)應(yīng)的頭像和昵稱,需要借助QQ官方提供的API接口來實(shí)現(xiàn)。下面是一個(gè)簡單的示例代碼:

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
public class QQInfoUtil {
public static void main(String[] args) {
String qq = "123456"; //需要獲取的QQ號(hào)
try {
URL url = new URL("http://r.qzone.qq.com/fcg-bin/cgi_get_portrait.fcg?uins=" + qq);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream(), "GBK"));
String line;
StringBuilder sb = new StringBuilder();
while((line = br.readLine()) != null) {
sb.append(line);
}
br.close();
conn.disconnect();
String resultJson = sb.toString();
String nickname = resultJson.split("\"")[1];
String avatarUrl = "http://q.qlogo.cn/g?b=qq&nk=" + qq + "&s=640";
System.out.println("QQ號(hào):" + qq);
System.out.println("昵稱:" + nickname);
System.out.println("頭像URL:" + avatarUrl);
} catch (Exception e) {
e.printStackTrace();
}
}
}

上述代碼中,通過訪問QQ官方提供的API接口,獲取到了對(duì)應(yīng)QQ號(hào)的頭像和昵稱信息,并輸出到控制臺(tái)上。其中,頭像URL的生成方式為:http://q.qlogo.cn/g?b=qq&nk=QQ號(hào)&s=SIZE,其中SIZE為頭像尺寸,可以根據(jù)需要調(diào)整。例如:s=640代表640*640的頭像。
