JAVA实现微信授权登录
1.先写一个工具类 AuthUtil.java 来存放APPID等信息
public class AuthUtil {
public static final String APPID = "换成自己的APPID ";
public static final String APPSECRET = "换成自己的APPSECRET ";
public static JSONObject doGetJson(String url) throws ClientProtocolException, IOException {
JSONObject jsonObject = null;
DefaultHttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(url);
HttpResponse response = client.execute(httpGet);
HttpEntity entity = response.getEntity();
if (entity != null) {
String result = EntityUtils.toString(entity, "UTF-8");
jsonObject = JSONObject.fromObject(result);
}
httpGet.releaseConnection();
return jsonObject;
}
}
2.新建一个 LoginController.java 类来实现授权登录
3.写一个页面来访问授权功能
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1">
<title>Insert title here</title>
</head>
<body>
授权成功！！！
${info }
</body>
</html>
<%@ page language="java" contentType="text/html; charset=UTF-8"
