laravel网站开发实例-----7
报名
实际上就是填写一个表单，然后存储到数据库中，然后管理员可以下载此数据库的内容，也就是说要生成excel。同时也要支持上传excel，用于存储账号密码。
完成对excel的支持
composer require “maatwebsite/excel:~2.1.0”
在config/app.php中加入
Maatwebsite\Excel\ExcelServiceProvider::class,
'Excel' => Maatwebsite\Excel\Facades\Excel::class,php artisan vendor:publish –provider=”Maatwebsite\Excel\ExcelServiceProvider”
用户报名
所有的报名信息放在同一张表，通过比赛id和schoolid来做限制，不过到后面有可能数据表里面的内容会很大，可以考虑分表。
报名表需要填写的字段
分为单人比赛和多人比赛
单人比赛：
学号、电话、邮箱、学院、专业、报名id、比赛id
多人比赛：
学号、电话、邮箱、学院、专业、队名、报名id(三个人有相同的报名id)、比赛id
1、创建数据库迁移
php artisan make:migration create_peoplebaomings_table –create=peoplebaomings
public function up()
{
Schema::create('peoplebaomings', function (Blueprint $table) {
$table->increments('id');
$table->integer('baomingid');
$table->bigInteger('schoolid');
$table->bigInteger('phone');
$table->string('email');
$table->string('xueyuan');
$table->string('zhuanye');
$table->string('duiming');
$table->timestamps();
});
}php artisan migrate
如果发现刚刚迁移的数据库差字段，可以回滚之后重新迁移，也可以追加字段，第一种比较简单，这里说说第二种方式
php artisan make:migration add_gameid_to_peoplebaomings
class AddGameidToPeoplebaomings extends Migration
{
public function up()
{
Schema::table('peoplebaomings',function(Blueprint $table){
$table->integer('gameid');
});
}
public function down()
{
Schema::table('peoplebaomings',function(Blueprint $table){
$table->integer('gameid');
});
}
}然后执行 php artisan migrate 即可
2、创建模型
php artisan make:model Api\Models\Peoplebaoming
class Peoplebaoming extends Model
{
use Notifiable;
protected $table = "peoplebaomings";
protected $fillable = [
'baomingid','schoolid','phone','email','xueyuan','zhuanye','duiming','gameid',
];
protected $hidden = [
'schoolid','gameid',
];
}准备工作就绪
3、定制路由
//用户报名比赛
//单人报名
$api->post('danrenbaominggame','UsersController@baoming')
->name('api.danrenbaominggame.baoming');4、编写逻辑
public function baoming(Request $request){
$this->validate($request,[
'schoolid'=>'required|max:10',
'phone'=>'required|max:11',
'email'=>'required',
'gameid'=>'required',
]);
$game = Game::where('id',$request->gameid)->first();
if($game->gamestatus==0){
$gameidnumber = Gameidnumber::where('gameid',$request->gameid)->first();//
Peoplebaoming::create([
'baomingid' => $gameidnumber->number,
'schoolid' => $request->schoolid,
'phone' => $request->phone,
'email' => $request->email,
'xueyuan' => $request->xueyuan,
'zhuanye' => $request->zhuanye,
'gameid' => $request->gameid,
]);
$gameidnumber->number = $gameidnumber->number+1;
$gameidnumber->save();
$game->number = $gameidnumber->number;
$game->save();
return $this->response->array([
'info' => '报名成功',
'status_code' => 200,
])->setStatusCode(200);
}else{
$this->response->array([
'info' => '该竞赛暂时无法报名',
'status_code'=>400,
])->setStatusCode(200);
}
}5、测试
{
"info": "报名成功",
"status_code": 200
}管理员下载报名信息(.xls)
1、定制路由
//管理员下载报名表
$api->post('downloadbaoming','GamesController@downloadbmb')
->name('api.downloadbaoming.downloadbmb');2、逻辑
$peoplebaomings=Peoplebaoming::where('gameid',$gameid)->get();
//使用这个方法从数据库中取出数据，然后需要转换成excel并支持下载
$arraypeoplebaomings = $peoplebaomings->toArray();
//使用这个方法将模型转化为数组
Excel::create('报名信息',function($excel) use ($arraypeoplebaomings){
$excel->sheet('详细信息', function($sheet) use ($arraypeoplebaomings){
$sheet->rows($arraypeoplebaomings);
});
})->export('xls');
//生成excel整个获取报名表的逻辑为
public function downloadbmb(Request $request){
$this->validate($request,[
'key' => 'required',
'gameid' => 'required',
]);
$key = $request->key;
if($request->session()->has($key)){
$gameid = $request->gameid;
$peoplebaomings=Peoplebaoming::where('gameid',$gameid)->get();
$arraypeoplebaomings = $peoplebaomings->toArray();
Excel::create('报名信息',function($excel) use ($arraypeoplebaomings){
$excel->sheet('详细信息', function($sheet) use ($arraypeoplebaomings){
$sheet->rows($arraypeoplebaomings);
});
})->export('xls');
}else{
return $this->response->array([
'info' => '请登录后重试',
'status_code' => 400,
])->setStatusCode(200);
}
}3、测试
使用postman测试下载的功能，在点击send的时候，有个选项是 send and download 。执行即可
注意：在模型文件中(App/Models/中定义的 hidden 字段，在生成的excel中是不存在的)

分两步走，第一步，上传excel文件；第二步，解析excel文件存储到数据库中。
1、接收前端发来的excel文件，并进行存储
a、设置路由
//管理员上传账号密码的excel
$api->post('uploadpass','GamesController@uploadpass')
->name('api.uploadpass.uploadpass');b、逻辑
config/excel.php中，修改
‘to_ascii’ => false,
use Storage;
...
$file = $request->file('userpass');
if ($file->isValid()){
$realPath = $file->getRealPath();
$gameid = $request->gameid;
$filename = $gameid.'.xls';
Storage::disk('uploads')->put($filename, file_get_contents($realPath));
}
//获取并存储到本地然后需要从磁盘中拿出数据
$filename1 = Storage::disk('uploads')->get($filename);
//这是从excel表中拿出所有数据,而不是拿出路径
//现在我需要做的是拿出路径，可以用下面的硬编码的方法
$filename1 = 'storage\app\uploads\\'.$filename;报错如下：
message”: “iconv(): Detected an illegal character in input string”,
这个是编码的问题，修改编码就可以了。
整个逻辑的代码
public function uploadpass(Request $request){
$this->validate($request,[
'key' => 'required',
'gameid' => 'required',
]);
$key = $request->key;
if($request->session()->has($key)){
$file = $request->file('userpass');
if ($file->isValid()){
$realPath = $file->getRealPath();
$gameid = $request->gameid;
$filename = $gameid.'.xls';
Storage::disk('uploads')->put($filename, file_get_contents($realPath));
$filename1 = 'storage\app\uploads\\'.$filename;
Excel::load($filename1, function($reader) {
$data = $reader->get();
dd($data);
});
}else{
return $this->response->array([
'info' => '文件上传失败',
'status_code' => 400,
])->setStatusCode(200);
}
}else{
return $this->response->array([
'info' => '请登录后重试',
'status_code' => 400,
])->setStatusCode(200);
}
}我上传的数据

} 关键信息中包含了所有上传的东西，现在得取出来放到数据库中去
最后完成的代码
public function uploadpass(Request $request){
$this->validate($request,[
'key' => 'required',
'gameid' => 'required',
]);
$key = $request->key;
if($request->session()->has($key)){

if ($file->isValid()){
$realPath = $file->getRealPath();
$gameid = $request->gameid;
$filename = $gameid.'.xls';
$content = Storage::disk('uploads')->get($filename);
if($content!=null){
$cunzai = 1;
}else{
$cunzai = 0;
}
Storage::disk('uploads')->put($filename, file_get_contents($realPath));
$filename1 = 'storage\app\uploads\\'.$filename;
$tablename = 'game_'.$gameid.'_pass';
Excel::load($filename1, function($reader) use ($tablename,$cunzai){
$reader = $reader->getSheet(0);
//获取表中的数据
$data = $reader->toArray();
$result = $this->create_table($tablename,$data,$cunzai);
});
return $this->response->array([
'info' => '上传成功',
'status_code' => 200,
])->setStatusCode(200);
}else{
return $this->response->array([
'info' => '文件上传失败',
'status_code' => 400,
])->setStatusCode(200);
}
}else{
return $this->response->array([
'info' => '请登录后重试',
'status_code' => 400,
])->setStatusCode(200);
}
}
//create_table代码
public function create_table($table_name,$arr_field,$chu_zai)
{
$tmp = $table_name;
$va = $arr_field;
if($chu_zai==1) Schema::drop($tmp);//加了一个判断用于避免重复生成数据表
Schema::create("$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;
}
});
$value_str= array();
$id = 1;
foreach($va as $key => $value){
if($key != 0){
$content = implode(",",$value);
$content2 = explode(",",$content);

$news = "$id,".$news;
DB::insert("insert into $tmp values ($news)");
//$value_str = '';
$value_str= array();
$id = $id + 1;
}
}
return 1;
}c、测试
{
"info": "上传成功",
"status_code": 200
}至此，用户报名、管理员下载报名信息、管理员上传账号密码的部分就写完了
下一讲 实现管理员批量给参赛者发邮件、单独发邮件
