微信企業號開發—通訊錄

          上篇博客介紹了聊天功能，這裏介紹通訊錄是如何實現的。首先要加載公司的所有部門，樹形結構，然後點擊進入部門的人員列表，點擊人員能查看詳細信息。

一、界面

         公司部門的樹形結構：

    部門成員列表：

        個人詳細信息：

二、代碼實現

1.controller

        /**
	 * 加載部門列表
	 */
	@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);
	}
	
	
	/**
	 * 加載部門成員列表
	 */
	@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";
	}
	
	
	/**
	 * 查看員工詳細信息
	 */
	@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

	/**
	 * 加載部門列表
	 */
	public List<JsonTree> getTree(){
		//1.先獲取token
		String accessToken = CommonUtil.getAccessToken("wxe510946434680dab", "eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0").getAccessToken();
		//2.獲取部門列表
		List<Department> departmentList = AdvancedUtil.getDepartment(accessToken);
		//根據部門列表轉換爲頁面需要的格式
		List<JsonTree> jsList = this.convertList(departmentList);
		return jsList;
	}
	
	/**
	 * 轉爲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;
    }
	
	/**
	 * 加載部門成員列表
	 */
	public List<UserDetail> getUserDetail(String deptId){
		//1.先獲取token
		String accessToken = CommonUtil.getAccessToken("wxe510946434680dab", "eWTaho766INvp4e1MCsz1mHYuT2DAleb62REQ3vsFizhY4vtmwZpKweuxUVh33G0").getAccessToken();
		
		//2.根據部門id和token的值獲取部門成員列表
		List<UserDetail> userDetail = AdvancedUtil.getUserDetail(accessToken, deptId);
		
		return userDetail;
	}

3.工具類

//獲取部門列表
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;
	}

//獲取部門成員詳情
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;
	}

	 		if (treeNode.isParent) {
				var childrenNodes = treeNode.children;
				if (childrenNodes) {
					for (var i = 0; i < childrenNodes.length; i++) {
						result += ',' + childrenNodes[i].id;

 		 $(document).ready(function(){

三、總結

            通訊錄功能並沒有想象中的難，樹結構採用ztree框架，後臺查到的數據必須轉換爲ztree定義的名稱，然後部門成員列表的顯示和查詢用到jquery mobile，在以後的博客中再介紹這種js的使用，從名字上就知道它是專門爲手機頁面開發的。
