标题: dataobject分布式接口出现SOFTBUS_PERMISSION_DENIED错误如何解决
[md]### 【问题描述】

1. 调用出现 createsession函数出现 SOFTBUS\_PERMISSION\_DENIED,也就是-268369911错误
2. 相关代码
//申请权限
const char **perms = new const char *[3];
perms[0] = "ohos.permission.DISTRIBUTED_DATASYNC";
perms[1] = "ohos.permission.DISTRIBUTED_SOFTBUS_CENTER";
perms[2] = "ohos.permission.ACCESS_SERVICE_DM";
TokenInfoParams infoInstance = {
.dcapsNum = 0,
.permsNum = 3,
.aclsNum = 0,
.dcaps = nullptr,
.perms = perms,
.acls = nullptr,
.processName = "dataObject",
.aplStr = "system_core",
};
uint64_t tokenId = GetAccessTokenId(&infoInstance);
SetSelfTokenID(tokenId);
OHOS::Security::AccessToken::AccessTokenKit::AccessTokenKit::ReloadNativeTokenInfo();
//检查权限
int res;
res = OHOS::Security::AccessToken::AccessTokenKit::VerifyAccessToken(tokenId, "ohos.permission.DISTRIBUTED_DATASYNC");
std::cout<<"res:"<<res<<std::endl;
res = OHOS::Security::AccessToken::AccessTokenKit::VerifyAccessToken(tokenId, "ohos.permission.DISTRIBUTED_SOFTBUS_CENTER");
std::cout<<"res:"<<res<<std::endl;
res = OHOS::Security::AccessToken::AccessTokenKit::VerifyAccessToken(tokenId, "ohos.permission.ACCESS_SERVICE_DM");
std::cout<<"res:"<<res<<std::endl;

//数据变化
bool RegisterObserver()
{
bool result = true;
std::shared_ptr<MockObjectWatcher> watcher = std::make_shared<MockObjectWatcher>();
uint32_t status = objectStore_->Watch(object_, watcher);
std::cout<<"objectStore->Watch status:"<<status<<std::endl;
return result;
}

//监听设备上下线

bool NotifyStatusAndNotifyChange()
{
// std::shared_ptr<FlatObjectStorageEngine> storageEngine = std::make_shared<FlatObjectStorageEngine>();
// storageEngine->Open("com.example.myapplication");
// uint32_t ret = storageEngine->CreateTable(TABLESESSIONID);
// if (ret != SUCCESS) {
//    return false;
// }
//    std::map<std::string, std::vector<uint8_t>> filteredData;
// storageEngine->NotifyChange(sessionId, filteredData);
// storageEngine->NotifyStatus(sessionId, deviceId, status);
auto notifierPtr = std::shared_ptr<StatusNotifier>();
uint32_t ret = objectStore_->SetStatusNotifier(notifierPtr);
std::cout<<"objectStore->SetStatusNotifier ret:"[ret<std::endl;notifycachedstatus(sessionid);"<deviceid<<"<"<status<<std::endl;DeleteTable(TABLESESSIONID);
return true;
}](%3Cret%3C%3Cstd::endl;%0AobjectStore_-)

3、总结

目测无问题，相关接口返回值也正常，本地可以进行正常的增删改查，但分布式无法使用，无法获取对端设备数据变动，请问这个问题是权限问题还是什么？我觉得是callinguid（）获取失败导致，但是不知道是什么原因

### 【运行环境】

硬件：rk3588
ROM版本：OpenHarmony4.0

更新新版本，打印uio是0，获取的权限失败
