java微信企业号开发之通讯录

前端技术 2023/09/01 Java

上篇文章中介绍了聊天功能，这里介绍通讯录是如何实现的。首先要加载公司的所有部门，树形结构，然后点击进入部门的人员列表，点击人员能查看详细信息。 

一、界面

公司部门的树形结构：

部门成员列表： 

个人详细信息： 

二、代码实现
1.controller 

  /**
 * 加载部门列表
 */
 @RequestMapping(\"/addressListDepartmentjsp.do\")
 public void addressListDepartment(HttpServletRequest request, HttpServletResponse response) throws IOException{
 request.setCharacterEncoding(\"utf-8\");
 response.setCharacterEncoding(\"utf-8\");
 
  List<JsonTree> jsList = addressListService.getTree();
  JSONArray jsonArray = JSONArray.fromObject(jsList);
  PrintWriter out = response.getWriter();
  out.print(jsonArray);
 }
 
 
 /**
 * 加载部门成员列表
 */
 @RequestMapping(\"/addressListUserList.do\")
 public String addressListuserList(HttpServletRequest request,HttpServletResponse response) throws UnsupportedEncodingException{
 request.setCharacterEncoding(\"utf-8\");
 response.setCharacterEncoding(\"utf-8\");
 String deptId=request.getParameter(\"Departmentid\");
 String d=request.getParameter(\"departmentName\");
 String departmentName = new String(d.getBytes(\"ISO-8859-1\"),\"utf-8\");
 List<UserDetail> userDetail = addressListService.getUserDetail(deptId);
 
 request.setAttribute(\"userDetail\", userDetail);
 request.setAttribute(\"departmentName\", departmentName);
 return \"addressListUserList\";
 }
 
 
 /**
 * 查看员工详细信息
 */
 @RequestMapping(\"/addressListUserInfo.do\")
 public String addressListuserInfo(HttpServletRequest request,HttpServletResponse response) throws UnsupportedEncodingException{
 request.setCharacterEncoding(\"utf-8\");
 response.setCharacterEncoding(\"utf-8\");
 
 String n=request.getParameter(\"name\");
 String name = new String(n.getBytes(\"ISO-8859-1\"),\"utf-8\");
 String mobile=request.getParameter(\"mobile\");
 String email=request.getParameter(\"email\");
 String weixinid=request.getParameter(\"weixinid\");
 String avatar=request.getParameter(\"avatar\");
 String d=request.getParameter(\"departmentName\");
 String departmentName = new String(d.getBytes(\"ISO-8859-1\"),\"utf-8\");
 request.setAttribute(\"name\", name);
 request.setAttribute(\"mobile\", mobile);
 request.setAttribute(\"email\",email);
 request.setAttribute(\"weixinid\", weixinid);
 request.setAttribute(\"avatar\", avatar);
 request.setAttribute(\"departmentName\", departmentName);
 
 return \"addressListUserInfo\";
 }

2.serviceImpl

 /**
 * 加载部门列表
 */
 public List<JsonTree> getTree(){
 //1.先获取token
 String accessToken = CommonUtil.getAccessToken(\"wxe510946434680dab\", \"eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0\").getAccessToken();
 //2.获取部门列表
 List<Department> departmentList = AdvancedUtil.getDepartment(accessToken);
 //根据部门列表转换为页面需要的格式
 List<JsonTree> jsList = this.convertList(departmentList);
 return jsList;
 }
 
 /**
 * 转为ZTree的格式
 */
 public List<JsonTree> convertList( List<Department> departmentList)
 {
  List<JsonTree> rootNode = new ArrayList<JsonTree>();
  
  for (int i = 0; i < departmentList.size(); i++) {
   for (int j = i+1; j <departmentList.size(); j++) {
   if (departmentList.get(i).getId()==departmentList.get(j).getParentid()) {
  JsonTree jt = new JsonTree();
  jt.setId(departmentList.get(i).getId());
  jt.setName(departmentList.get(i).getName());
  jt.setpId(departmentList.get(i).getParentid());
  jt.setOpen(false);
  jt.setUrl(\"\");
  rootNode.add(jt);
  break;
 }else {
  JsonTree jt = new JsonTree();
  jt.setId(departmentList.get(i).getId());
  jt.setName(departmentList.get(i).getName());
  jt.setpId(departmentList.get(i).getParentid());
  jt.setOpen(false);
  jt.setUrl(\"addressListUserList.do?Departmentid=\"+departmentList.get(i).getId()+\"&departmentName=\"+departmentList.get(i).getName());
  
  rootNode.add(jt);
  break;
 }
 }

 }
  return rootNode;
 }
 
 /**
 * 加载部门成员列表
 */
 public List<UserDetail> getUserDetail(String deptId){
 //1.先获取token
 String accessToken = CommonUtil.getAccessToken(\"wxe510946434680dab\", \"eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0\").getAccessToken();
 
 //2.根据部门id和token的值获取部门成员列表
 List<UserDetail> userDetail = AdvancedUtil.getUserDetail(accessToken, deptId);
 
 return userDetail;
 }

3.工具类

//获取部门列表
public static List<Department> getDepartment(String accessToken) {
 List<Department> departmentList = null;
 // https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=ACCESS_TOKEN
 String requestUrl = \"https://qyapi.weixin.qq.com/cgi-bin/department/list?access_token=ACCESS_TOKEN\";
 requestUrl = requestUrl.replace(\"ACCESS_TOKEN\", accessToken);
 
 JSONObject jsonObject = CommonUtil.httpsRequest(requestUrl, \"GET\", null);

 if (null != jsonObject) {
 try {
 departmentList = JSONArray.toList(jsonObject.getJSONArray(\"department\"), Department.class);
 } catch (JSONException e) {
 departmentList = null;
 int errorCode = jsonObject.getInt(\"errcode\");
 String errorMsg = jsonObject.getString(\"errmsg\");
 
 }
 }
 return departmentList;
 }//获取部门成员详情
public static List<UserDetail> getUserDetail(String accessToken,String departmentId){
 List<UserDetail> userDetail = null;
 String requestUrl = \"https://qyapi.weixin.qq.com/cgi-bin/user/list?access_token=ACCESS_TOKEN&department_id=DEPARTMENT_ID&fetch_child=1&status=0\";
 requestUrl = requestUrl.replace(\"ACCESS_TOKEN\", accessToken).replace(\"DEPARTMENT_ID\", departmentId);
 
 JSONObject jsonObject = CommonUtil.httpsRequest(requestUrl, \"GET\", null);

 if (null != jsonObject) {
 try {
 userDetail = JSONArray.toList(jsonObject.getJSONArray(\"userlist\"),UserDetail.class);
 } catch (JSONException e) {
 userDetail = null;
 int errorCode = jsonObject.getInt(\"errcode\");
 String errorMsg = jsonObject.getString(\"errmsg\");
 
 }
 }
 return userDetail;
 }

4.js 

<script type=\"text/javascript\">
 var curMenu = null, zTree_Menu = null;
 var setting = {
 view: {
 showLine: false,
 showIcon: false,
 selectedMulti: false,
 dblClickExpand: false,
  addDiyDom: addDiyDom
 },
 data: {
 simpleData: {

 var zNodes = null;
 $.ajax({
 type : \"post\",
  async: false,
 url :\"addressListDepartmentjsp.do\",
 success : function(data) {
 zNodes = eval(\'(\' + data + \')\');
 },
 error : function(data) { 
  
 }
 });
 
 function addDiyDom(treeId, treeNode) {
 var spaceWidth = 5;
 var switchObj = $(\"#\" + treeNode.tId + \"_switch\"),
 icoObj = $(\"#\" + treeNode.tId + \"_ico\");
 switchObj.remove();
 icoObj.before(switchObj);

 if (treeNode.level > 1) {
 var spaceStr = \"<span style=\'display: inline-block;width:\" + (spaceWidth * treeNode.level)+ \"px\'></span>\";

 if(str!=\"\"){
 treeNode.url=\"\";
 var zTree = $.fn.zTree.getZTreeObj(\"treeDemo\");
 zTree.expandNode(treeNode);
 return false;
 }
 if(str==\"\"){
 
 }
 return true;
 }
 
// 张晓 朱丹
 function getAllChildrenNodes(treeNode,result){
 //var strResult=result;
 if (treeNode.isParent) {
 var childrenNodes = treeNode.children;
 if (childrenNodes) {
  for (var i = 0; i < childrenNodes.length; i++) {
  result += \',\' + childrenNodes[i].id;
  }
 }
 }
 return result;
 }
 $(document).ready(function(){
 var treeObj = $(\"#treeDemo\");
 $.fn.zTree.init(treeObj, setting, zNodes);
 zTree_Menu = $.fn.zTree.getZTreeObj(\"treeDemo\");
 curMenu = zTree_Menu.getNodes()[0].children[0].children[0];
 zTree_Menu.selectNode(curMenu);

 treeObj.hover(function () {
 if (!treeObj.hasClass(\"showIcon\")) {
  treeObj.addClass(\"showIcon\");
 }
 }, function() {
 treeObj.removeClass(\"showIcon\");
 });
 });

 <style type=\"text/css\">

 </style>
 </head>

 <body>
 <div data-role=\"page\" id=\"UserMain\">
 <div class=\"content_wrap\" style=\"width:96%;height:98%;margin-left: auto;margin-right: auto;\" >
 <div class=\"zTreeDemoBackground left\" style=\"width:100%;height:98%;\" >
 <ul id=\"treeDemo\" class=\"ztree\" style=\"width:98%;height:98%;\" ></ul>
 </div>
 </div>
 <span id=\"zNodes\"></span>
 </div>
 </body>

三、总结
通讯录功能并没有想象中的难，树结构采用ztree框架，后台查到的数据必须转换为ztree定义的名称，然后部门成员列表的显示和查询用到jquery mobile，在以后的文章中再介绍这种js的使用，从名字上就知道它是专门为手机页面开发的。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持phpstudy。
