这大概也许可能就是我写的第一个php接口，之前在学校有写过jsp、php的增删改查，但不是接口的。是那种前后端不分离，一起写的。

# 代码 #

## 1.School.php ##

<?php
    namespace app\api\controller;
    use think\Request;
    use app\api\model\CoachInfo;
    use app\api\common\ApiResultUtils;
    /**

    class School
    {
    	/**
    	 * *
    	 * 查询驾校相关教练
    	 */
    	public function queryCoachList()
    	{
    		$request = Request::instance();
    		
    		if ($request->isGet()) {
    			if (!$request->has('schoolId')) {
    				return ApiResultUtils::offFail('schoolId is empty');
    			}
    			$schoolId = $request->get('schoolId');
    
    			$coachDAO = new CoachInfo();
    			$coachList = $coachDAO->queryCoachListBySchoolId($schoolId);
    			if (empty($coachList)) {
    				return ApiResultUtils::offFail('没有数据');
    			}
    			return ApiResultUtils::ofSuccess($coachList);
    
    		}else{
    			return ApiResultUtils::offFail('http method error,need GET');
    		}
    	}

## 2.Coachinfo.php ##
