# Http 常用返回状态码

200 : (OK) 服务器已成功处理了请求。 通常,这表示服务器提供了请求的网页。 201 : (Created) 请求成功并且服务器创建了新的资源。 301 : (Moved Permanently) 请求的网页已永久移动到新位置。 服务器返回此响应(对 GET 或 HEAD 请求的响应)时,会自动将请求者转到新位置。 300 : (多种选择) 针对请求,服务器可执行多种操作。 服务器可根据请求者 (user agent) 选择一项操作,或提供操作列表供请求者选择。 303 : (查看其他位置) 请求者应当对不同的位置使用单独的 GET 请求来检索响应时,服务器返回此代码。 304 : (Not Modified) 自从上次请求后,请求的网页未修改过。 服务器返回此响应时,不会返回网页内容。 400 : (Bad Request) 服务器不理解请求的语法。 401 : (Unauthorized) 请求要求身份验证。 对于需要登录的网页,服务器可能返回此响应。 403 : (Forbidden) 服务器拒绝请求。 404 : (Not Found ) 服务器找不到请求的网页。 500 : (Internal Server Error) 服务器遇到错误,无法完成请求。

# 数据返回

laravel, 在thinkphp中吧json 改为 data

/**
 * 成功返回消息
 * @param string $msg
 * @param array $data
 * @param int $code
 * @return \Illuminate\Http\JsonResponse
 */
public function success($msg="ok",$data=[],$code=0){
    if (!empty($data)) return response()->json(["code"=>$code,"data"=>$data,"msg"=>$msg]);
    return response()->json(["code"=>$code,"msg"=>$msg]);
}

/**
 * 失败返回消息
 * @param string $msg
 * @param int $code
 * @return \Illuminate\Http\JsonResponse
 */
public function error($msg="请求错误",$code=202){
    return response()->json(["code"=>$code,"msg"=>$msg]);
}

/**
 * 数据返回
 * @param array $data
 * @param string $count
 * @param string $msg
 * @param int $code
 * @return \Illuminate\Http\JsonResponse
 */
public function resData($data=[],$count = '',$msg="ok",$code=0){
    if (empty($count)) return response()->json(["code"=>$code,"msg"=>$msg,"data"=>$data]);
    return response()->json(["code"=>$code,"data"=>$data,"count"=>$count,"msg"=>$msg]);
}

# 查询技巧

# join

$data = Score::alias('s')
    ->join("gift g",'s.sid=g.id')
    ->field("g.id,g.title,g.pic,s.stime") //需要那个表的字段就假如对应表的字段
    ->where("uid",$request->uid)
    ->limit(($page * $limit) - $limit, (int)$limit)
    ->select()->toArray();

# 别名查询

$data = Articles::where("del",0)
            ->alias('a')
            ->join('wy_comment c','a.id=c.aid')
            ->field("a.id,a.title,,COUNT(c.aid) as comCount")
            ->limit(($page * $limit) - $limit, (int)$limit)
            ->order("id","desc")->select()->toArray();
            
$data = Articles::where("del",0)
            ->field("id,title,keyword,pic,createtime,click")
            ->limit(($page * $limit) - $limit, (int)$limit)
            ->withCount('ArcToCom')
            ->order("id","desc")->select()->toArray();
            
//关联查询
 ->with(['user','parent'])
 ->visible(['user'=>['realname'],'parent'=>['realname']])
 
//关联统计


http://localhost:8082/ArticleDetail?eid=26&puid=100

# 关联查询

 ->with(['user','parent']) //模型关联方法,不是模型的名字
 ->visible(['user'=>['realname'],'parent'=>['realname']])

# 分页查询

// contoller
public function list(){
    $limit = $request->param("limit", 15);
    $data = User::order("id","desc")->paginate($limit);
    //获取查询数据
    $list = $data->items();
    // 获取总条数
    $count = $data->total();
    // json 返回
    return json(["code"=>201,"data"=>$list,"count"=>$count]);
}

# 时间段查询

/**
 * 时间段查询:2020-10-01 - 2020-11-30
 * @param string $datebt
 * @return array
 */
protected function getBetweenTime(string $datebt){
    $datearr=explode(" - ",$datebt);

    $dateend=strtotime($datearr['1']);
    return ['create_time','between',[$datebegin,$dateend]];

# A表关联B表,统计B表统计排名

用户可根据分享文章获得的收益sum之后进行排名

UserModel

// 关联浏览记录
    public function visit()
    {
        return $this->hasMany(Visit::class,"muid","id");
    }

controller

$top = User::withSum("visit","mprize")->order("visit_sum","desc")->select()->toArray();

# A表关联B表统计B表信息

关联模型

//cate->school

/**
     * 分类关联资源
     */
public function school()
{
    return $this->hasMany(School::class,'cate_id','id');
}

分类关联资源统计资源的状态为1和2的总数

$data = SchoolCate::withCount([
    "school"=>function($query,&$alias){ //这里有一个&符号
        $query->where("status",2)->where("check_user_id",session("admin_id"));
        $alias='valid';
    }

    ->withCount([
        "school"=>function($query,&$alias){
            $query->where("status",4)->where("check_user_id",session("admin_id"));
            $alias='unvalid';
        }
    ],false)->where("id","in",$school->getMySchoolIds())->select();

# 获取器

获取器的作用是在获取数据的字段值后自动进行处理,例如,我们需要对状态值进行转换,1 代表:正常

在model下定义: 语法:get + 字段名+Attr

class User extends Model
{
      public function getStatusAttr($value)
      {
	    $status = [-1=>'删除',0=>'禁用',1=>'正常',2=>'待审核'];
            return $status[$value];
      }
}
// 查询输出
$user = User::find()->status; //例如输出“正常”

class User extends Model 
{
    public function getStatusAttr($value)
    {
       $status = [-1=>'删除',0=>'禁用',1=>'正常',2=>'待审核'];
       return ['val'=>$value,'text'=>$status[$value]];
  }
}

$user = User::find()->status; //例如输出“正常”
$user = User::find()->status.text; //例如输出“1”

$user = User::find();
$user->getData("status"); //例如输出“1”

# 远程一对一查询

/**
     * 【座位表】通过【班级表】去查【教室】
     * 座位关联班级,班级关联教室: 通过【座位】关联【班级】去查【教室】
     * 参数:教室模型(目标表),班级模型(中间表),座位表id(目标表),班级表id(中间表),座位表关联班级的关联id(起始表),班级表关联教室的id(中间表)

# 一次性插入大量数据处理

    }

简单粗暴方法

// $list 是一个1W 条二维数组数据,每次插入 1000条
Model::limit(1000)->insertAll($list);

# 动态查询

// 根据邮箱(email)查询用户信息
User::whereEmail('[email protected]')
    ->find();

// 根据昵称(nick_name)查询用户
User::whereNickName('like', '%流年%')
    ->select();
    
// 根据邮箱查询用户信息
User::getByEmail('[email protected]');
    
// 根据昵称(nick_name)查询用户信息
User::getByNickName('流年');
    
// 根据邮箱查询用户的昵称
User::getFieldByEmail('[email protected]', 'nick_name');
    
// 根据昵称(nick_name)查询用户邮箱
User::getFieldByNickName('流年', 'email');

# 字段比较

可以直接比较两个字段的大小进行查询

User::whereColumn('update_time', '>', 'create_time')
    ->select();
User::whereColumn('score1', '>', 'score2')
    ->select();

如果需要比较两个字段相同,可以使用

User::whereColumn('score1', 'score2')
    ->select();

# 时间表达式查询

对于一些非具体的时间查询,比较适合使用时间表达式进行查询,例如:

// 获取今天的博客
Blog::whereTime('create_time', 'today')
    ->select();
    
// 获取昨天的博客
Blog::whereTime('create_time', 'yesterday')
    ->select();
    
// 获取本周的博客
Blog::whereTime('create_time', 'week')
    ->select();   
    
// 获取上周的博客
Blog::whereTime('create_time', 'last week')
    ->select();    
    
// 获取本月的博客
Blog::whereTime('create_time', 'month')
    ->select();   
    
// 获取上月的博客
Blog::whereTime('create_time', 'last month')
    ->select();      
    
// 获取今年的博客
Blog::whereTime('create_time', 'year')
    ->select();    
    
// 获取去年的博客
Blog::whereTime('create_time', 'last year')
    ->select();     

# 关联删除

/**
     * 删除
     */
    public function delete(Request $request)
    {
        $id = $request->param("id/d");
        $delData = Dks::with(["dkUser","theme","bm","prize","prize"])->find($id);
        try {
            $delData->together(["dkUser","theme","bm","prize"])->delete();
        }catch (\ErrorException $e){
            return error($e->getMessage());
        }
        return success("删除成功!");
    }

    public function batchDel(Request $request)
    {
        $ids = $request->param("ids"); //[1,2,3]
        try {
            foreach ($ids as $item){
                Dks::with(["dkUser","theme","bm","prize","prize"])->find($item)->together(["dkUser","theme","bm","prize","prize"])->delete();
            }
        }catch (\ErrorException $e){
            return error($e->getMessage());
        }
        return success("删除成功!");
    }

# 排名统计

假设一个用户去玩一款游戏,每次结束后会产生一个分数,那么一个用户就有多条记录分值的记录,如何在同一张表中统计 每个玩家最高分在总玩家的排名

条件:一张用户表(user),一个记录玩家成绩的记录表(score)(一个玩家有多条记录,我们要取最高分进行排名)

1、去重查询所有用户的id (score)

$allUserIds = Score::distinct(true)->field("uid")->column("uid");

2、通过关联统计的方式查询所有用户的最高分

$data = User::whereIn("id",$allUserIds)->field("id")->withMax("boy","score")->field("id")->select()->toArray(); // boy为关联方法,score为score表的分数字段
// user模型关联方法
public function boy()
{
    return $this->hasMany(Score::class,"uid","id");//用 用户表的id,关联积分表的uid
}

3、使用一个foreach 循环

$myTop = 0;
foreach ($data as $item){
    if ($item['boy_max'] > $score){
        $myTop +=1;
    }
}
echo $myTop = $myTop+1;

# JWT-AUTH使用方发

https://gitee.com/thans/jwt-auth

中间件形式:

// app/config/middleware

'alias'    => [
        "Auth" => thans\jwt\middleware\JWTAuth::class,
    ],
// controller
protected $middleware = ['Auth'];
$user = [
	"name" => "orangbus"
];
// thans/tp-jwt-auth/src/claim/Expiration 15行修改
return ["code" => 1,"msg" => "token已失效!"];
  • 获取toke

    $token = JWTAuth::builder($user);
    echo $token['name']; // orangbus
    
  • 验证token

    //登录验证
    JWTAuth::auth();
    
    // token验证
    JWTAuth::validate()
    
  • 刷新token

    JWTAuth::refresh(); //返回 token信息,之前的数据依旧存在
