我有一个脚本,该脚本应该(按顺序):
sys_get_temp_dir()
中创建一个文件夹,并在其中放置一些文件(在exec()
行中完成)我分别成功地尝试了步骤1和3,但努力使步骤2起作用。
我的脚本就是这个脚本(在我得到的错误下面):
<?php
$tmpdir = sys_get_temp_dir();
$outdir = "download";
$format = "ESRI Shapefile";
$folderToZip = $tmpdir . DIRECTORY_SEPARATOR . $outdir;
$command = "ogr2ogr -f $format $folderToZip WFS:\"https://www.wondermap.it/cgi-bin/qgis_mapserv.fcgi?&map=/home/ubuntu/qgis/projects/Demo_sci_WMS/demo_sci.qgs&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&typename=domini_sciabili&bbox=544138,5098446,564138,5108446\" --config GDAL_HTTP_UNSAFESSL YES";
exec($command);
// Initialize archive object
$zip = new ZipArchive();
$zipFile = "download.zip";
$zip->open($zipFile, ZipArchive::CREATE | ZipArchive::OVERWRITE);
// Create recursive directory iterator
/** @var SplFileInfo[] $files */
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($folderToZip),
RecursiveIteratorIterator::LEAVES_ONLY
);
foreach ($files as $name => $file)
{
// Skip directories (they would be added automatically)
if (!$file->isDir())
{
// Get real and relative path for current file
$filePath = $file->getRealPath();
$relativePath = substr($filePath, strlen($folderToZip) + 1);
// Add current file to archive
$zip->addFile($filePath, $relativePath);
}
}
// Zip archive will be created only after closing object
$zip->close();
header("Content-Description: File Transfer");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=" . $zipFile);
readfile ($zip);
exit();
?>
我得到的错误:
Fatal error: Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(C:\Users\MINORA~1.ONE\AppData\Local\Temp\download,C:\Users\MINORA~1.ONE\AppData\Local\Temp\download): Impossibile trovare il percorso specificato.
Warning: Unknown: Cannot destroy the zip context in Unknown on line 0
答案 0 :(得分:0)
不知道上面的代码是否正确/正确,但结果发现错误中缺少$format
中$command
周围的双引号,从而导致没有输出,因此{{1 }}未创建。
我忘了放它们了,因为我认为一个字符串变量会包含这些变量,但是当然,这只是构造一个字符串变量的方式。我要么必须做$folderToZip
(而不是$format = "'ESRI Shapefile'";
),要么(这就是我所做的),我需要像在$format = "ESRI Shapefile";
中明确地在其周围加上双引号,例如
$command
,写$command = "ogr2ogr -f \"$format\" $folderToZip WFS:\"https://www.wondermap.it/cgi-bin/qgis_mapserv.fcgi?&map=/home/ubuntu/qgis/projects/Demo_sci_WMS/demo_sci.qgs&SERVICE=WFS&VERSION=1.1.0&REQUEST=GetFeature&typename=domini_sciabili&bbox=544138,5098446,564138,5108446\" --config GDAL_HTTP_UNSAFESSL YES";
而不是\"$format\"
。
