对接飞书，根据userid获取用户信息

飞书的开发文档里面有一个api是根据userid获取单个用户信息的接口
后台实现：
1：首先需要获取token,因为飞书提供的获取单个用户信息的接口中，token是必传参数，所以需要先获取token。
按照飞书官网里面提供的获取token的方式去获取，我目前项目中的是企业自建应用，那么就调用获取 app_access_token（企业自建应用）的接口就行，如下：

https://open.feishu.cn/document/ukTMukTMukTM/ukDNz4SO0MjL5QzM/auth-v3/auth/app_access_token_internal

该接口中详细说明了已什么方式请求，请求头需要设置什么，请求体需要传递什么，然后我们就可以通过postman去测试下：


调用成功后 会返回如下格式：

{
    "app_access_token": "",//这里就不贴出来了，隐藏了哈~
    "code": 0,
    "expire": 2318,
    "msg": "ok",
    "tenant_access_token": ""//这里就不贴出来了，隐藏了哈~
}

后台实现：
1：获取token

/**
 * 获取飞书token
 */
public class GetToken {


    /**
     * 获取飞书token
     * @return
     */
    public static String fsToke(){
        String token = null;
        Map<String,String> param = new HashMap<>();
        param.put("app_id", FsConstants.App_ID);
        param.put("app_secret",FsConstants.App_Secret);
        // 设置请求头信息
        Map<String,String> headParam = new HashMap<>();
        String result = HttpClientUtil.connectPost(FsConstants.Access_Token_Url,headParam,param);
        JSONObject jsonObject = JSONObject.parseObject(result);
        if(jsonObject.get("msg").equals("ok")){
            token = (String) jsonObject.get("tenant_access_token");
        }
        return token;
    }
}

2：根据userId获取单个用户信息，我这里的业务需求是获取名字，我只需要从返回的data中获取名字就行，这里单独写了一个方法，因为其他地方也用得到。
先用postman调用接口：

成功后响应的数据格式，data里面就是我们需要的信息：

{
    "code": 0,
    "msg": "success",
    "data": {
        "user": {
            "union_id": "on_94a1ee5551019f18cd73d9f111898cf2",
            "user_id": "3e3cf96b",

                "avatar_640": "https://foo.icon.com/xxxx",

            },

                    "user_order": 100,
                    "department_order": 100
                }
            ],
            "custom_attrs": [
                {
                    "type": "TEXT",
                    "id": "DemoId",
                    "value": {
                        "text": "DemoText",
                        "url": "http://www.feishu.cn",
                        "pc_url": "http://www.feishu.cn",
                        "option_value": "option",
                        "name": "name",
                        "picture_url": "https://xxxxxxxxxxxxxxxxxx",
                        "generic_user": {

                        }
                    }
                }
            ],
            "enterprise_email": "[email protected]",
            "job_title": "xxxxx"
        }
    }
}

代码实现：
// 我需要的是这个人的姓名，所以只返回了name,其他的信息都可以在data中拿到

   //根据用户id获取名字
    public String getNameByUserId(String userId){
        String name = "";
        String token = commonFS.getToken();
        String url = FsConstants.alone_User_Info_Url+userId;
//        String url1 = url + "userId";
        Map<String, String> param = new HashMap<>();
        param.put("user_id_type", "user_id");
        // 设置请求头信息
        Map<String, String> headParam = new HashMap<>();
        headParam.put("Authorization", token);
        if(StringUtils.isNotEmpty(userId)){
            String result = HttpClientUtil.doGet(url, headParam,param);
            Map<String, Object> jsonObject = (Map) JSONObject.parseObject(result);
            if (!StringUtils.isEmpty(jsonObject) && jsonObject.get("msg").equals("success")) {
                JSONObject data = (JSONObject) jsonObject.get("data");
                name = JSONObject.parseObject(data.getString("user")).getString("name");
            }
        }
        return name;
    }

commonFS类，用来获取token

public class CommonFS {

    public JSONObject getInfoFromFS(JSONObject event) {

        //设置头部信息
        Map<String, String> headerParam = new HashMap<>();
        String token = getToken();
        headerParam.put("Authorization", token);
        String url = FsConstants.Approval_Detail_Url;
        //构造参数
        Map<String, String> paramMap = new HashMap<>();
        String code = event.getString("instance_code");
        String userId = event.getString("user_id");
        paramMap.put("instance_code", code);
        paramMap.put("locale", "zh-CN");
        paramMap.put("user_id", userId);
        log.info("请求飞书接口参数为：" + paramMap.toString());
        //调用飞书接口
        String result = HttpClientUtil.doPost(url, headerParam, paramMap);
        JSONObject jsonObject = JSONObject.parseObject(result);
        if (StringUtils.isNotEmpty(jsonObject)) {
            //调用失败
            if (!"0".equals(jsonObject.getString("code"))) {
                log.info("飞书返回码:" + jsonObject.getString("code"));
                throw new BaseException("调用飞书接口失败");
            } else {
                //调用成功
                return jsonObject;
            }
        }
        return new JSONObject();
    }

    /**
     * 获取token
     *
     * @return
     */
    public String getToken() {
        String tenant_access_token = GetToken.fsToke();
        return "Bearer" + " " + tenant_access_token;
    }
}

GetToken类：

/**
 * 获取飞书token
 */
public class GetToken {


    /**
     * 获取飞书token
     * @return
     */
    public static String fsToke(){
        String token = null;
        Map<String,String> param = new HashMap<>();
        param.put("app_id", FsConstants.App_ID);
        param.put("app_secret",FsConstants.App_Secret);
        // 设置请求头信息
        Map<String,String> headParam = new HashMap<>();
        String result = HttpClientUtil.connectPost(FsConstants.Access_Token_Url,headParam,param);
        JSONObject jsonObject = JSONObject.parseObject(result);
        if(jsonObject.get("msg").equals("ok")){
            token = (String) jsonObject.get("tenant_access_token");
        }
        return token;
    }
}

FsConstants类：定义了一些请求的路径

/**
 * 飞书参数定义配置类
 */
public class FsConstants {
    public static final String User_Info_Url = "https://open.feishu.cn/open-apis/contact/v3/users";
    //获取单个用户
    public static final String alone_User_Info_Url = "https://open.feishu.cn/open-apis/contact/v3/users/";
    //查询日或者月统计的统计数据
    public static final String AttendanceDaysOrMonth_Url = "https://open.feishu.cn/open-apis/attendance/v1/user_stats_datas/query?employee_type=";
    //获取token
    public static final String Access_Token_Url = "https://open.feishu.cn/open-apis/auth/v3/app_access_token/internal"; 
    //获取部门信息列表
    public static final String DepartMents_Url = "https://open.feishu.cn/open-apis/contact/v3/departments"; 
    // 根部门返回数据可能没有名称
    public static final String DEFAULT_NAME = "123";
    //获取父部门信息列表
    public static final String Parent_DepartMents_Url = "https://open.feishu.cn/open-apis/contact/v3/departments/parent"; 
    //正式服务上的，这里就不贴了~
    public static final String App_ID = "";
    //正式服务上的，这里就不贴了~
    public static final String App_Secret = "";
    //测试appid
    //public static final String App_ID = "";
    //测试密钥
    //public static final String App_Secret = "";
   
    //获取单个审批实例详情
    public static final String Approval_Detail_Url = "https://www.feishu.cn/approval/openapi/v2/instance/get"; 
}
