导入在线/生成的csv的PHPExcel问题

Question

我对 PHPExcel 有一些问题，它一直抛出无法读取（生成）文件，这里是代码：

include 'PHPExcel/PHPExcel.php';

$rtype = $_REQUEST['rtype'];    
// set headers to redirect output to client browser as a file download
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="report_'.$rtype.'.xls"');
header('Cache-Control: no-cache');
header('Pragma: no-cache');
header('Expires: 0');

//-----Create a reader, set some parameters and read in the file-----
$objReader = PHPExcel_IOFactory::createReader('CSV');
$objReader->setDelimiter(','); 
$objReader->setEnclosure('');
$objReader->setLineEnding("\r\n");
$objReader->setSheetIndex(0);
$objPHPExcel = $objReader->load('db_report.php?rtype='.$rtype.'&type=csv');

//-----Create a Writer and output the file to the browser-----
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');

已经检查了 db_report.php 并且它输出了一个 csv 文件，所以这个文件没有错

Answer 1

您尝试加载字符串值 'db_report.php?rtype='.$rtype.'&type=csv' 是不是 url。

加载第一个数据，例如：

$data = file_get_contents('http://domen.com/db_report.php?rtype='.$rtype.'&type=csv');
$objPHPExcel = $objReader->load($data);
