PHP登入session的擷取

這篇文章主要介紹了關於PHP登入session的擷取，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下

登入時記錄session

/** *執行登入 */public function doLogin(){$condition['name'] = $username = trim($_POST['username']);$condition['password'] = $password = md5(trim($_POST['password']));//稍後在加驗證碼驗證邏輯//$imgCode = $_POST['imgCode'];if (empty($username) || empty($password)) {$this->ajaxReturn(null,C("ERR_MSG_70"),"success:false");}$user = D("User")->relation(true)->where($condition)->find();if(empty($user)){$this->ajaxReturn(null,"使用者名稱或者密碼錯誤","success:false");}if(empty($user['apps']) && $user['role'] != UserModel::ADMIN){$this->ajaxReturn(null,'該使用者不屬於任何一條產品線，不允許登入,請聯絡管理員！','success:false');}if (empty($user)) {$this->ajaxReturn(null,C("ERR_MSG_70"),"success:false");}$defaultAppId = $user['defaultApp'] >= 0 ? $user['defaultApp'] :  $user['apps'][0]['id'];foreach ($user['apps'] as $app){if ($app['id'] == $defaultAppId){$appName = $app['appName'];break;}}$session = array('uid'=>$user['id'],'username'=>$username,'role'=> $user['role'],'appId' => $defaultAppId,'appName'=>$appName);setSession($session);$this->ajaxReturn($data,"恭喜，登入成功！","success:true");}

具體頁面使用時，action中session的擷取

 public function deploy()    {        $username = session('username');        $conditions = explode(",", $_POST['environment']);        $envarr = array();        foreach ($conditions as $condition) {            $envIds = D('Env')->field('name,IP')                ->where("name like'" . $condition . "%'")                ->select();                        foreach ($envIds as $key => $envId) {                $envIds[$key]['mem'] = $this->getCPUMEM($envId['IP']);            }                        $envIdsSort = $this->my_sort($envIds, 'mem', SORT_ASC, SORT_STRING);            // $envIds=array_remove($envIds,'mem');            $envarray['env'] = $condition;            $envarray['smallIP'] = $envIdsSort[0]['IP'];            $envarr[] = $envarray;        }        $_POST['environment'] = json_encode($envarr);        $_POST['username']=$username;                $resultnew = $this->request("localhost:8080/execute/isbuildingNew.html", $_POST, "POST");        // var_dump($resulenew);        if ($resultnew == "building:true") {            $this->ajaxReturn(1, '前一次構建進行中中，請稍候重試！', 'success:false');        } else {            $result = $this->request("localhost:8080/execute/onlineDeployNew.html", $_POST, "POST");            if ($result) {                $this->ajaxReturn(1, $result, 'success:true');            } else {                $this->ajaxReturn(0, "提交構建失敗", 'success:false');            }        }    }

然後後端就能擷取到這個username了，soeasy！
