钉钉里如何创建服务群？_问答-阿里云开发者社区

首先你要创建一个普通群
请求示例（HTTP）

POST https://oapi.dingtalk.com/topapi/im/chat/scenegroup/create?access_token=ACCESS_TOKEN

请求正文

{
        "title":"测试群",
        "template_id":"c354***-***-***-b4ea-6f1ab***65",
        "owner_user_id":"022*****",
        "user_ids":"072*****,013*****",
        "subadmin_ids":"072*****,013*****",
        "uuid":"axcf*-*****-*****-23da*",
        "icon":"@lADOADma*****QKA",
        "mention_all_authority":0,
        "show_history_type":0,
        "validation_type":0,
        "searchable":0,
        "chat_banned_type":0,
        "management_type":0,    
        "only_admin_can_ding":0,
        "all_members_can_create_mcs_conf":1,
        "all_members_can_create_calendar":0,
        "group_email_disabled":0,
        "only_admin_can_set_msg_top":0, 
        "add_friend_forbidden":0,
        "group_live_switch":1,
        "members_to_admin_chat":0
}

请求示例（JAVA SDK，接口使用旧版服务端SDK）

DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/topapi/im/chat/scenegroup/create");
OapiImChatScenegroupCreateRequest req = new OapiImChatScenegroupCreateRequest();
req.setTitle("测试群");
req.setTemplateId("c354***-***-***-b4ea-6f1ab***65");
req.setOwnerUserId("022*****");
req.setUserIds("072*****,013*****");
req.setSubadminIds("072*****,013*****");
req.setUuid("axcf*-*****-*****-23da*");
req.setIcon("@lADOADma*****QKA");
req.setMentionAllAuthority(0L);
req.setShowHistoryType(0L);
req.setValidationType(0L);
req.setSearchable(0L);
req.setChatBannedType(0L);
req.setManagementType(0L);
req.setOnlyAdminCanDing(0L);
req.setAllMembersCanCreateMcsConf(1L);
req.setAllMembersCanCreateCalendar(0L);
req.setGroupEmailDisabled(0L);
req.setOnlyAdminCanSetMsgTop(0L);
req.setAddFriendForbidden(0L);
req.setGroupLiveSwitch(1L);
req.setMembersToAdminChat(0L);
OapiImChatScenegroupCreateResponse rsp = client.execute(req, access_token);
System.out.println(rsp.getBody());

接着把普通群升级为服务群
java代码如下

public class Sample {

    public static com.aliyun.dingtalkservice_group_1_0.Client createClient() throws Exception {
        Config config = new Config();
        config.protocol = "https";
        config.regionId = "central";
        return new com.aliyun.dingtalkservice_group_1_0.Client(config);
    }

    public static void main(String[] args_) throws Exception {
        java.util.List<String> args = java.util.Arrays.asList(args_);
        com.aliyun.dingtalkservice_group_1_0.Client client = Sample.createClient();
        UpgradeNormalGroupHeaders upgradeNormalGroupHeaders = new UpgradeNormalGroupHeaders();
        upgradeNormalGroupHeaders.xAcsDingtalkAccessToken = "<your access token>";
        UpgradeNormalGroupRequest upgradeNormalGroupRequest = new UpgradeNormalGroupRequest()
                .setOpenGroupSetId("Jciwxxx")
                .setTemplateId("6b7ae69d-0f9f-4xxx")
                .setOpenConversationId("cidxxxxxx==")
                .setOpenTeamId("Jciwnfw");
        try {
            client.upgradeNormalGroupWithOptions(upgradeNormalGroupRequest, upgradeNormalGroupHeaders, new RuntimeOptions());
        } catch (TeaException err) {
            if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
                // err 中含有 code 和 message 属性，可帮助开发定位问题
            }

        } catch (Exception _err) {
            TeaException err = new TeaException(_err.getMessage(), _err);
            if (!com.aliyun.teautil.Common.empty(err.code) && !com.aliyun.teautil.Common.empty(err.message)) {
                // err 中含有 code 和 message 属性，可帮助开发定位问题
            }

        }        
    }
}
