Java钉钉开发_02_免登授权（身份验证）-阿里云开发者社区

源码已上传GitHub: https://github.com/shirayner/DingTalk_Demo

一、本节要点

1.免登授权的流程

（1）签名校验

（2）获取code,并传到后台

（3）根据code获取userid

（4）根据userid获取用户信息，（此处可进行相应业务处理）

（5）将用户信息传到前端，前端拿到用户信息，并做相应处理

2.计算签名信息（signature）

2.1 待签名参数

ticket	jsapi_ticket
nonceStr	随机字符串，随机生成
timeStamp	时间戳
url	当前网页的URL，不包含#及其后面部分

2.2签名流程

（1）字典序

将所有待签名参数按照字段名的ASCII 码从小到大排序（字典序）后，使用URL键值对的格式（即 key1=value1&key2=value2…）拼接成字符串string1

如：String string1= "jsapi_ticket=" + jsTicket + "&noncestr=" + nonceStr + "&timestamp=" + timeStamp + "&url=" + url;

（2）SHA-1签名，得到 signature

/**
     * @desc ： 3.生成签名的函数 
     *  
     * @param ticket jsticket
     * @param nonceStr 随机串，自己定义
     * @param timeStamp 生成签名用的时间戳 
     * @param url 需要进行免登鉴权的页面地址，也就是执行dd.config的页面地址 
     * @return
     * @throws Exception String
     */
    
    public static String getSign(String jsTicket, String nonceStr, Long timeStamp, String url) throws Exception {  
        String plainTex = "jsapi_ticket=" + jsTicket + "&noncestr=" + nonceStr + "&timestamp=" + timeStamp + "&url=" + url;
        System.out.println(plainTex);
        try {  
            MessageDigest crypt = MessageDigest.getInstance("SHA-1");
            crypt.reset();
            crypt.update(plainTex.getBytes("UTF-8"));
            return byteToHex(crypt.digest());
        } catch (NoSuchAlgorithmException e) {  
            throw new Exception(e.getMessage());  
        } catch (UnsupportedEncodingException e) {  
            throw new Exception(e.getMessage());  
        }  
    }  

    //将bytes类型的数据转化为16进制类型  
    private static String byteToHex(byte[] hash) {
        Formatter formatter = new Formatter();
        for (byte b : hash) {
            formatter.format("%02x", new Object[] { Byte.valueOf(b) });
        }
        String result = formatter.toString();
        formatter.close();
        return result;
    }

3.签名校验的流程

3.1 后端准备好前端校验参数

后台方法：getConfig(HttpServletRequest)

    public static String getConfig(HttpServletRequest request){  

        //1.准备好参与签名的字段
        /* 
         *以http://localhost/test.do?a=b&c=d为例 
         *request.getRequestURL的结果是http://localhost/test.do 
         *request.getQueryString的返回值是a=b&c=d 
         */  
        String urlString = request.getRequestURL().toString();
        String queryString = request.getQueryString();

        String queryStringEncode = null;
        String url;
        if (queryString != null) {
            queryStringEncode = URLDecoder.decode(queryString);
            url = urlString + "?" + queryStringEncode;
        } else {
            url = urlString;
        }


        String nonceStr=UUID.randomUUID().toString();      //随机数
        long timeStamp = System.currentTimeMillis() / 1000;     //时间戳参数  

        String signedUrl = url;
        String accessToken = null;
        String ticket = null;
        String signature = null;       //签名

        //2.进行签名，获取signature
        try {  
            accessToken=AuthHelper.getAccessToken(Env.CORP_ID, Env.CORP_SECRET);  

            ticket=AuthHelper.getJsapiTicket(accessToken);  
            signature=getSign(ticket,nonceStr,timeStamp,signedUrl);  


        } catch (Exception e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }  

        System.out.println("accessToken:"+accessToken);
        System.out.println("ticket:"+ticket);
        System.out.println("nonceStr:"+nonceStr);
        System.out.println("timeStamp:"+timeStamp);
        System.out.println("signedUrl:"+signedUrl);
        System.out.println("signature:"+signature);
        System.out.println("agentId:"+Env.AGENTID);
        System.out.println("corpId:"+Env.CORP_ID);
        
        
        
           String configValue = "{jsticket:'" + ticket + "',signature:'" + signature + "',nonceStr:'" + nonceStr + "',timeStamp:'"
                    + timeStamp + "',corpId:'" + Env.CORP_ID + "',agentId:'" + Env.AGENTID + "'}";
            System.out.println(configValue);

        return configValue;  
    }

3.2 前端接收后台参数

在前端调用后端方法，获取dd.config所需的校验参数：‘url’，‘nonceStr’，‘agentId’，‘timeStamp’，‘corpId’，‘signature’。

<script type="text/javascript">
    var _config =<%=com.ray.dingtalk.auth.AuthHelper.getConfig(request)%>;
</script>

View Code

3.3 执行前端 dd.config ，进行签名校验

dd.config 用接收到的 nonceStr、agentId、timeStamp、corpId这四个参数去钉钉官方后端计算出一个签名（signature ），并将这个签名与我们后端所计算的signature来进行比对，若一致，则校验通过。若不一致，则是我们后端计算签名的时候出错了。此时可根据错误消息提示去进行调试。

dd.config({
    agentId : _config.agentId,
    corpId : _config.corpId,
    timeStamp : _config.timeStamp,
    nonceStr : _config.nonceStr,
    signature : _config.signature,
    jsApiList : [                           //需要调用的借口列表 
        'runtime.info',
        'biz.contact.choose',            //选择用户接口  
        'device.notification.confirm', 
        'device.notification.alert',   //confirm,alert,prompt都是弹出小窗口的接口     
        'device.notification.prompt', 
        'biz.ding.post',
        'biz.util.openLink' ]
});

3.4 异常：js加载顺序有误所引起的前端什么信息都不提示

出现这个原因，可能是自己js出错了。我的原因是js加载顺序有误。

请注意这几个js的加载顺序： _config，jquery-3.2.1.min.js 必须在auth.js之前加载

<script src="js/jquery-3.2.1.min.js"></script>
<script type="text/javascript" src="http://g.alicdn.com/dingding/open-develop/1.6.9/dingtalk.js"></script>

<script type="text/javascript">
    var _config =<%=com.ray.dingtalk.auth.AuthHelper.getConfig(request)%>;
</script>
<script type="text/javascript" src="js/auth.js"></script>

View Code

4. 将code送往后端：ajax

签名校验成功之后，即dd.config校验成功之后，会执行dd.ready函数，这时我们就可以使用钉钉的jsapi了。

签名校验成功后，我们就可以调用获取免登授权码(CODE)的jsapi，来获取code，然后通过ajax方式将这个code传到后台userInfoServlet

 /**获取免登授权码 CODE
     * 
     */
    dd.runtime.permission.requestAuthCode({  
        corpId : _config.corpId,  
        onSuccess : function(info) {                                                   //成功获得code值,code值在info中  
            alert('authcode: ' + info.code);  
            /* 
             *$.ajax的是用来使得当前js页面和后台服务器交互的方法 
             *参数url:是需要交互的后台服务器处理代码，userInfoServlet
             *参数type:指定和后台交互的方法，因为后台servlet代码中处理Get和post的doGet和doPost 
             *data:负责传递请求参数
             *其中success方法和error方法是回调函数，分别表示成功交互后和交互失败情况下处理的方法 
             */  
            $.ajax({  
                type : "POST",
                url : "http://p65s3p.natappfree.cc/DingTalk_Demo/userInfoServlet",
                data : {
                    code : info.code
                },
                success : function(data, status, xhr) {
                    alert(data);
                    var userInfo = JSON.parse(data);

                    document.getElementById("userName").innerHTML = userInfo.name;
                    document.getElementById("userId").innerHTML = userInfo.userid;

                    // 图片
                    if(info.avatar.length != 0){
                        var img = document.getElementById("userImg");
                        img.src = info.avatar;
                        img.height = '200';
                        img.width = '200';
                    }

                },
                error : function(xhr, errorType, error) {  
                    logger.e("yinyien:" + _config.corpId);  
                    alert(errorType + ', ' + error);  
                }  
            });  

        },  
        onFail : function(err) {                                                       //获得code值失败  
            alert('fail: ' + JSON.stringify(err));  
        }  
    });

5.根据code获取userid

    private static final String GET_USERINFO_BYCODE_URL="https://oapi.dingtalk.com/user/getuserinfo?access_token=ACCESSTOKEN&code=CODE";

/** 5.根据免登授权码Code查询免登用户userId
     * @desc ：钉钉服务器返回的用户信息为：
     * userid    员工在企业内的UserID
     * deviceId    手机设备号,由钉钉在安装时随机产生
     * is_sys    是否是管理员
     * sys_level    级别，0：非管理员 1：超级管理员（主管理员） 2：普通管理员（子管理员） 100：老板
     *  
     * @param accessToken
     * @param code
     * @throws Exception void
     */
    public JSONObject getUserInfo(String accessToken,String code) throws Exception {

        //1.获取请求url
        String url=GET_USERINFO_BYCODE_URL.replace("ACCESSTOKEN", accessToken).replace("CODE", code);

        //2.发起GET请求，获取返回结果
        JSONObject jsonObject=HttpHelper.httpGet(url);
        System.out.println("jsonObject:"+jsonObject.toString());

        //3.解析结果，获取User
        if (null != jsonObject) {  
            //4.请求成功,则返回jsonObject
            if (0==jsonObject.getInteger("errcode")) {
                return jsonObject;
            }
            //5.错误消息处理
            if (0 != jsonObject.getInteger("errcode")) {  
                int errCode = jsonObject.getInteger("errcode");
                String errMsg = jsonObject.getString("errmsg");
                throw new Exception("error code:"+errCode+", error message:"+errMsg); 
            }  
        }   

        return null;
    }

6.根据userid获取用户信息

    private static final String GET_USER_URL="https://oapi.dingtalk.com/user/get?access_token=ACCESSTOKEN&userid=USERID";


    /** 2.根据userid获取成员详情
     * @desc ：获取成员详情
     *   参考文档： https://open-doc.dingtalk.com/docs/doc.htm?spm=0.0.0.0.jjSfQQ&treeId=371&articleId=106816&docType=1#s0
     * @param accessToken
     * @param userId void
     * @throws Exception 
     */
    public JSONObject getUser(String accessToken, String userId) throws Exception {

        //1.获取请求url
        String url=GET_USER_URL.replace("ACCESSTOKEN", accessToken).replace("USERID", userId);

        //2.发起GET请求，获取返回结果
        JSONObject jsonObject=HttpHelper.httpGet(url);
        System.out.println("jsonObject:"+jsonObject.toString());
        //3.解析结果，获取User
        if (null != jsonObject) {  
            //4.请求成功,则返回jsonObject
            if (0==jsonObject.getInteger("errcode")) {
                return jsonObject;
            }
            //5.错误消息处理
            if (0 != jsonObject.getInteger("errcode")) {  
                int errCode = jsonObject.getInteger("errcode");
                String errMsg = jsonObject.getString("errmsg");
                throw new Exception("error code:"+errCode+", error message:"+errMsg); 
            }  
        }   

        return null;
    }

7.将用户信息传到前端

注意：传输格式为json

//3.通过userid换取用户信息
            JSONObject jsonObject=us.getUser(accessToken, userId);
            result=JSON.toJSON(jsonObject);


PrintWriter out = response.getWriter(); 
        out.print(result);  
        out.close();  
        out = null;

View Code

8.前端接收用户信息后做相应处理

jsp中代码：

<div align="center">
        <img id="userImg" alt="头像" src="">
    </div>

    <div align="center">
        <span>UserName:</span>
        <div id="userName" style="display: inline-block"></div>
    </div>

    <div align="center">
        <span>UserId:</span>
        <div id="userId" style="display: inline-block"></div>
    </div>

View Code

js中代码：发送code的ajax调用成功后

success : function(data, status, xhr) {
                    alert(data);
                    //接收后端发送过来的用户信息
                    var userInfo = JSON.parse(data);

                    //收到用户信息后所做的处理
                    document.getElementById("userName").innerHTML = userInfo.name;
                    document.getElementById("userId").innerHTML = userInfo.userid;

                    // 图片
                    if(info.avatar.length != 0){
                        var img = document.getElementById("userImg");
                        img.src = info.avatar;
                        img.height = '200';
                        img.width = '200';
                    }

                },

二、代码实现

1.钉钉参数配置——Env.java

将Env.java中的配置修改成你自己的

package com.ray.dingtalk.config;

/**@desc  : 企业应用接入时的常量定义
 * 
 * @author: shirayner
 * @date  : 2017年9月27日 下午4:57:36
 */

public class Env {

    /**
     * 企业应用接入秘钥相关
     */
    public static final String CORP_ID = "ding6d4828968696691535c2f4657eb6378f";
    public static final String CORP_SECRET = "ZigmkCY4VcsGUhLIzmfxOmP0ElJbGI5uBhn-2mPelovnjPcA6e4LrjpYXQQw89Q4";
    public static final String SSO_Secret = "YgIGtCHmcwAmOuKsAo_lgqJJiOwyez2G6vBvhCf1zwR6kZ5DGMJsxOcUgK5p1C";
    public static final String AGENTID = "128838526";
    
    
    /**
     * DING API地址
     */
    public static final String OAPI_HOST = "https://oapi.dingtalk.com";
    /**
     * 企业应用后台地址，用户管理后台免登使用
     */
    public static final String OA_BACKGROUND_URL = "";


    /**
     * 企业通讯回调加密Token，注册事件回调接口时需要传递给钉钉服务器
     */
    public static final String TOKEN = "";
    public static final String ENCODING_AES_KEY = "";
