管理员批量给参赛者发邮件、单独发邮件

功能详情
管理员登录到后台，点击批量发送账号密码，就给所有报名的选手发送账号密码。
单独给某人发邮件需要填写手动填写账号密码。

批量发送账号密码

注册路由

//管理员批量发送邮件
$api->post('sendpass','GamesController@sendpass')
    ->name('api.sendpass.pass');
//管理员单独给某人发邮件
$api->post('sendpassone','GamesController@sendpassone')
    ->name('api.sendpassone.sendpassone');

写逻辑

取一个表出来，单独分配模型

$baomingusers = Peoplebaoming::where('gameid',$gameid)->get(['schoolid','email']);
foreach ($baomingusers as $baominguser){
   if($i==$cnt){
       $flag=1;
       $news = $news.','."'$baominguser->schoolid'".','."'$baominguser->email'";
       break;
   }
   $i++;
}
//循环获取某个自己需要的东西

修改了上传账号密码时生成的数据表，加上了schoolid和email，所以取的时候直接取就可以了

public function sendpass(Request $request){
    $this->validate($request,[
       'key' => 'required',
       'gameid' => 'required',
    ]);
    $key = $request->key;
    if($request->session()->has($key)){
        //生成分配的账号密码数据表
        $gameid = $request->gameid;
        $dbpass = 'game_'.$gameid.'_pass';
        $sql = 'select * from '.$dbpass;
        $pass = DB::select($sql);
        $i = 0 ;
        foreach ($pass as $onepass){
            //发送邮件
            $email = $onepass->email;
            Mail::send('sendpass',['schoolid' => $onepass->schoolid,'username' => $onepass->login_id,'password' => $onepass->password],function($message) use ($email){
                $to = $email;
                $message ->to($to)->subject('比赛账号密码');
            });
        }
        return $this->response->array([
            'info' => '发送成功',
            'status_code' => 200,
        ])->setStatusCode(200);
    }else{
        return $this->response->array([
            'info' => '请登录后重试',
            'status_code' => 400,
        ])->setStatusCode(200);
    }

}

修改后的创建上传的数据表

public function create_table($table_name,$arr_field,$chu_zai,$gameid)
{

    $tmp = $table_name;
    $va = $arr_field;
    if($chu_zai==1) Schema::drop($tmp);
    Schema::create("$tmp", function(Blueprint $table) use ($tmp,$va)
    {
        $fields = $va[0];  //列字段
        //$fileds_count =  0; //列数
        $table->increments('id');//主键
        foreach($fields as $key => $value){
            if($key == 0){
                $table->string($fields[$key])->nullable();//->unique(); 唯一
            }else{
                $table->string($fields[$key])->nullable();
            }
            //$fileds_count = $fileds_count + 1;
        }
        $table->bigInteger('schoolid')->nullable();
        $table->string('email')->nullable();
    });

    $value_str= array();
    $id = 1;
    //获取报名表的所有学号和邮箱
    $baomingusers = Peoplebaoming::where('gameid',$gameid)->get(['schoolid','email']);
    $cnt=0;
    foreach($va as $key => $value){
        if($key != 0){

            $content = implode(",",$value);
            $content2 = explode(",",$content);
            foreach ( $content2 as $key => $val ) {
                $value_str[] = "'$val'";
            }
            $news = implode(",",$value_str);
            $news = "$id,".$news;
            //从报名数据库拿出每个数据放进到这个数据库中
            $i=0;
            $flag=0;
            foreach ($baomingusers as $baominguser){
                if($i==$cnt){
                    $flag=1;
                    $news = $news.','."'$baominguser->schoolid'".','."'$baominguser->email'";
                    break;
                }
                $i++;
            }
            if($flag==0)continue;
            DB::insert("insert into $tmp values ($news)");
            //$value_str = '';
            $value_str= array();
            $id = $id + 1;
            $cnt++;
        }
    }
    return 1;
}

模板

学号为 {{$schoolid}} 同学您好，本次比赛您的账号为 {{$username}}，密码为 {{$password}} ，请妥善保管您的账号密码，祝您生活愉快。

发送个人账号密码

//如果这个用户有账号密码，就直接发，如果这个用户没有账号密码，就接收前端传来的账号密码

注意，用 $pass = DB::select($sql); 取出来的东西是一个对象数组，要使用的话必须用循环或者用 $pass[$i] 的形式

使用 DB::insert(“insert into $dbpass values ($news)”); 的时候，自增的id没有自增，非常奇怪。只有从数据库中拿出当前最大的id为多少，然后 insert 进去了。

public function sendpassone(Request $request){
   $this->validate($request,[
      'key' => 'required',
      'gameid' => 'required',
      'schoolid' => 'required',
   ]);
   //如果这个用户有账号密码，就直接发，如果这个用户没有账号密码，就接收前端传来的账号密码
   $key = $request->key;
   if($request->session()->has($key)){
       $gameid = $request->gameid;
       $dbpass = 'game_'.$gameid.'_pass';
       $schoolid = $request->schoolid;
       $where = 'where `schoolid`='.$schoolid;
       $sql = 'select * from '.$dbpass.' '.$where;
       $pass = DB::select($sql);
       if($pass==null){
           $login_id =$request->loginid;
           $password = $request->password;
           $email = $request->email;
           $sql2 = 'select count(*) as total from '.$dbpass;
           $numberpass = DB::select($sql2);
           $number = $numberpass[0]->total+1;
           $news = "$number,'your_own_nick','$login_id','$password',$schoolid,'$email'";
           DB::insert("insert into $dbpass values ($news)");
           $game = Game::where('id',$gameid)->first();
           Mail::send('sendpass',['schoolid' => $schoolid,'username' => $login_id,'password' => $password,'gamename' => $game->gamename,'gametime' => $game->gametime,'address'=>$game->address],function($message) use ($email){
               $to = $email;
               $message ->to($to)->subject('比赛账号密码');
           });
       }else{
           $email = $pass[0]->email;
           $game = Game::where('id',$gameid)->first();
           Mail::send('sendpass',['schoolid' => $schoolid,'username' => $pass[0]->login_id,'password' => $pass[0]->password,'gamename' => $game->gamename,'gametime' => $game->gametime,'address'=>$game->address],function($message) use ($email){
               $to = $email;
               $message ->to($to)->subject('比赛账号密码');
           });
       }
       return $this->response->array([
           'info' => '发送成功',
           'status_code' => 200,
       ])->setStatusCode(200);
   }else{
       return $this->response->array([
           'info' => '请登录后重试',
           'status_code' => 400,
       ])->setStatusCode(200);
   }
}

导出账号密码对照表

路由

//账号密码对照表下载
$api->post('downloaduserpass','GamesController@downloaduserpass')
    ->name('api.downloaduserpass.downloaduserpass');

逻辑，可以仿照报名表的下载

public function downloaduserpass(Request $request){
    $this->validate($request,[
        'key' => 'required',
        'gameid' => 'required',
    ]);
    $key = $request->key;
    if($request->session()->has($key)){
        $gameid = $request->gameid;
        $dbpass = 'game_'.$gameid.'_pass';
        $sql = 'select * from '.$dbpass;
        $pass = DB::select($sql);
        $i = 0;
        $pass2 = array();
        foreach ($pass as $passone){
            $pass2[$i]['id'] = $passone->id;
            $pass2[$i]['team_name'] = $passone->team_name;
            $pass2[$i]['login_id'] = $passone->login_id;
            $pass2[$i]['password'] = $passone->password;
            $pass2[$i]['schoolid'] = $passone->schoolid;
            $pass2[$i]['email'] = $passone->email;
            $i++;
        }//只能接收二维数组，所以手动转换成二维数组
        Excel::create('比赛账号密码对照表',function($excel) use ($pass2){
            $excel->sheet('详细信息', function($sheet) use ($pass2){
                $sheet->rows($pass2);
            });
        })->export('xls');
    }else{
        return $this->response->array([
            'info' => '请登录后重试',
            'status_code' => 400,
        ])->setStatusCode(200);
    }
}

至此，用laravel开发网站博客就结束了，同学们可以把其他的接口补上，共勉。
