表设计原则

要考虑到以后单表体积

要把主要大字段分割出去

使用搜索引擎

记录多的话,要用第三方搜索引擎,分词器,elastic seacrch

后台登录

指定controller路径

用artisan创建控制器, php artisan make:controller admins/Account

<a name="KoKUE"></a>

创建路由

添加路由 Route::get('/admins/account/login','admins\Account@login'); ,注意命名空间反斜杠

  1. Route::get('/admins/account/login','admins\Account@login');

指定view路径

  1. return view('admins.account.login');

验证码

注意给验证码写路由

  1. /**
  2. * 验证码类
  3. */
  4. class VeriCode{
  5. // 获取验证码配置
  6. private static function _getCodeConfig(){
  7. return [
  8. // 验证码字符集
  9. 'codeStr' => 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789',
  10. // 验证码个数
  11. 'codeCount' => 4,
  12. // 字体大小
  13. 'fontsize' =>16,
  14. // 验证码的宽度
  15. 'width' => 100,
  16. // 验证码高度
  17. 'height' => 36,
  18. // 是否有干扰点?true有,false没有
  19. 'disturbPoint' => true,
  20. // 干扰点个数,disturbPoint开启后生效
  21. 'pointCount' => 200,
  22. // 是否有干扰条?true有,false没有
  23. 'disturbLine' => true,
  24. // 干扰条个数,disturbLine开启后生效
  25. 'lineCount' => 3
  26. ];
  27. }
  28. // 创建图片验证码
  29. public static function create(){
  30. // 配置
  31. $config = self::_getCodeConfig();
  32. //创建画布
  33. $image = imagecreatetruecolor($config['width'],$config['height']);
  34. //背景颜色
  35. $bgcolor=imagecolorallocate($image,255,255,255);
  36. imagefill($image,0,0,$bgcolor);
  37. $captch_code = '';//存储验证码
  38. $captchCodeArr = str_split($config['codeStr']);
  39. //随机选取4个候选字符
  40. for($i=0;$i<$config['codeCount'];$i++){
  41. $fontsize = $config['fontsize'];
  42. $fontcolor=imagecolorallocate($image,rand(0,120),rand(0,120),rand(0,120));//随机颜色
  43. $fontcontent = $captchCodeArr[rand(0,strlen($config['codeStr'])-1)];
  44. $captch_code.=$fontcontent;
  45. $_x = $config['width']/$config['codeCount'];
  46. $x=($i*(int)$_x)+rand(5,10); //随机坐标
  47. $y=rand(5,10);
  48. imagestring($image,$fontsize,$x,$y,$fontcontent,$fontcolor); // 水平地画一行字符串
  49. }
  50. session_start();
  51. $_SESSION['code']=$captch_code;
  52. //增加干扰点
  53. if($config['disturbPoint']){
  54. for($i=0;$i<$config['pointCount'];$i++){
  55. $pointcolor=imagecolorallocate($image,rand(50,200),rand(50,200),rand(50,200));
  56. imagesetpixel($image,rand(1,99),rand(1,29),$pointcolor);
  57. }
  58. }
  59. //增加干扰线
  60. if($config['disturbLine']){
  61. for($i=0;$i<$config['lineCount'];$i++){
  62. $linecolor=imagecolorallocate($image,rand(80,280),rand(80,220),rand(80,220));
  63. imageline($image,rand(1,99),rand(1,29),rand(1,99),rand(1,29),$linecolor);
  64. }
  65. }
  66. //输出格式
  67. header('content-type:image/png');
  68. imagepng($image);
  69. //销毁图片
  70. imagedestroy($image);
  71. }
  72. }

登录提交

定义post提交路由,用ajax的post提交登录数据
使用post提交注意添加@csrf

  1. function dologin(){
  2. var username = $.trim($('#username').val());
  3. var pwd = $.trim($('#password').val());
  4. var verifycode = $.trim($('#verifycode').val());
  5. if(username==''){
  6. layer.alert('请输入用户名',{icon:2});
  7. return;
  8. }
  9. if(pwd==''){
  10. layer.alert('请输入密码',{icon:2});
  11. return;
  12. }
  13. if(verifycode==''){
  14. layer.alert('请输入验证码',{icon:2});
  15. return;
  16. }
  17. var _token = $('input[name="_token"]').val();
  18. $.post('/admins/account/dologin',{username:username,pwd:pwd,verifycode:verifycode,_token:_token},function(res){
  19. if(res.code>0){
  20. reload_captcha();
  21. return layer.alert(res.msg,{icon:2});
  22. }
  23. layer.alert(res.msg,{icon:1});
  24. setTimeout(function(){
  25. window.location.href='/admins/home/index';
  26. },1000);
  27. },'json');
  28. }

控制器中用Request接收

  1. public function dologin(Request $req){
  2. $username = trim($req->username);
  3. $pwd = trim($req->pwd);
  4. $VeriCode = trim($req->verifycode);
  5. if ($username==''){
  6. return json_encode(array('code'=>1,'msg'=>'用户不能为空'));
  7. }
  8. if ($pwd==''){
  9. return json_encode(array('code'=>1,'msg'=>'密码不能为空'));
  10. }
  11. session_start();
  12. if (strtolower($VeriCode)!=strtolower($_SESSION['code'])){
  13. return json_encode(array('code'=>1,'msg'=>'验证码不正确'));
  14. }
  15. return json_encode(array('code'=>0,'msg'=>'登录成功'));
  16. }
