后端代码：

//上传文件处理
    public function uploadExcelAction()
    {   
        $targetFolder = '/public/uploadFile/';     // Relative to the root
　　　　 $salt = 'test';
        $verifyToken = md5($test . $_POST['guid']);
        if (!empty($_FILES) && $_POST['token'] == $verifyToken) {
            $tempFile = $_FILES['Filedata']['tmp_name'];
            $targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
            $targetFile = rtrim($targetPath,'/') . '/' . $verifyToken.'.xlsx';
            
            $fileTypes = array('xlsx'); 
            $fileParts = pathinfo($_FILES['Filedata']['name']);
            
            if (in_array($fileParts['extension'],$fileTypes)) {
                move_uploaded_file($tempFile,$targetFile);
                echo '1';
            } else {
                echo 'Invalid file type.';
            }
        }else{
            echo 'Invalid params.';
        }
        die;
    }

处理excel数据，就说两个关键点：取单元格的值和背景色

　　　　$objReader    = \PHPExcel_IOFactory::createReader('Excel2007');
       $objPHPExcel  = $objReader->load($targetFile);
       $sheet        = $objPHPExcel->getSheet();
       $sheetRows    = $sheet->getHighestDataRow();                                           // 取得总行数
       $sheetColumns = PHPExcel_Cell::columnIndexFromString($sheet->getHighestDataColumn());  //列数



//读取单元格
       $value     = $objPHPExcel->getActiveSheet()->getCell($columns[$k] . $j)->getValue();  //获取每个单元格的值
       $fillColor = $objPHPExcel->getActiveSheet()->getStyle($columns[$k] . $j)->getFill()->getStartColor()->getARGB();  //背景色
