weixin4j封装好的SnsComponent组件中的方法可以执行该步骤
WeixinUserInfoController :
package com.baigehuidi.demo.controller;
import com.baigehuidi.demo.loader.WeixinInsLoader;
import com.baigehuidi.demo.weixin4j.WeixinException;
import com.baigehuidi.demo.weixin4j.model.sns.SnsUser;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.HashMap;
import java.util.Map;
@RestController
@RequestMapping("/user")
public class WeixinUserInfoController {
@RequestMapping("/getSnsUserInfoByCode")
public Map getSnsUserInfoByCode(@RequestBody String code) throws WeixinException {
Map map = new HashMap();
System.out.println("code:"+code);
SnsUser snsUser = WeixinInsLoader.getWeixinInstance().sns().getSnsUserByCode(code);
map.put("SnsUser",snsUser);
return map;
}
}
这个控制层通过传入code返回SnsUser的用户实例.
前端是Ajax请求:
index.jsp : (或是什么html 也可以执行ajax请求)
前端继而解析json将用户的头像昵称等展示在页面之上.
<%@ page import="com.baigehuidi.demo.weixin4j.model.sns.SnsUser" %>
<%@ page import="com.baigehuidi.demo.weixin4j.component.SnsComponent" %>
<%@ page import="com.baigehuidi.demo.weixin4j.Weixin" %><%--

<%--<%=snsUser.getNickname()%>--%>
<!-- <button id="btn">btn</button> -->
<!-- 通过ajax获取的用户信息封装在data中,可以根据需要获取不同的参数,如 -->
<script>
// $("#btn").click(getSnsUser);
// function getSnsUser(){
// alert("getSnsUser begin")
$.ajax({
url:"/user/getSnsUserInfoByCode",
data:"<%=request.getParameter("code")%>",
contentType:"application/json",
dataType:"json",
method:"POST",
success:function(data){
alert(JSON.stringify(data));
//将数据反填到html或jsp页面上
}
});
// }
</script>
</body>
</html>
每个code只能使用一次,一次后作废.
当用户退出网页,再次点击网页授权,会再获取code值,再次执行如上操作.
其它的操作可见下图:
