我有一个getPass.php，它创建一个Pass实例。下面是代码：如何在iOS中调用一个函数用于iOS存折文件下载
//create new pass instance
$coupon = new Pass("pass/source");
//fill in dynamic data
$coupon->content['serialNumber'] = (string)uniqid();
$coupon->content['coupon']['secondaryFields'][0]['value'] =
(string)$_POST['name'];
$coupon->content['locations'][0] =
$locations[(int)$_POST['location']];
$coupon->writePassJSONFile();
$coupon->writeRecursiveManifest();
$coupon->writeSignatureWithKeysPathAndPassword("pass", '12345');
$fileName = $coupon->writePassBundle();
echo "File saved to - $fileName";
**/* THIS IS WHERE IM TRYING TO PRESENT IT */**
$this->outputPassBundleAsWebDownload($fileName);
然后Pass.php做了很多的东西，它的作品，因为香港专业教育学院用它收发邮件的工作通行证，但林与演示/下载功能取代了电子邮件功能。所以这里是Pass.php的代码：
<?php
class Pass {
private $workFolder = null;
private $ID = null;
var $content = null;
var $passBundleFile = null;
private function copySourceFolderFilesToWorkFolder($path) {
//recurse over contents and copy files
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path),
RecursiveIteratorIterator::SELF_FIRST);
foreach($files as $name => $fileObject){
if (is_file($name) &&
substr($fileObject->getFileName(), 0, 1)!=".") {
copy($name,
$this->workFolder."/".str_replace($path."/", "",$name));
} else if (is_dir($name)) {
mkdir($this->workFolder."/".
str_replace($path."/", "",$name));
}
}
}
//import a json file into the object
function readPassFromJSONFile($filePath) {
//read the json file and decode to an object
$this->content =
json_decode(file_get_contents($filePath),true);
}
//export a json file from the object
function writePassJSONFile() {
file_put_contents($this->workFolder."/pass.json",
json_encode($this->content));
}
//generate the manifest file
function writeRecursiveManifest() {
//create empty manifest
$manifest = new ArrayObject();
//recurse over contents and build the manifest
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($this->workFolder),
RecursiveIteratorIterator::SELF_FIRST);
foreach($files as $name => $fileObject){
if (is_file($name) &&
substr($fileObject->getFileName(), 0, 1)!=".") {
$relativeName = str_replace($this->workFolder.
"/","",$name);
$sha1 = sha1(file_get_contents(
$fileObject->getRealPath()
));
$manifest[$relativeName] = $sha1;
}
}
//printf debug
// print_r($manifest);
//write the manifest file
file_put_contents($this->workFolder."/manifest.json",
json_encode($manifest));
}
//generate the bundle signature
function writeSignatureWithKeysPathAndPassword($keyPath, $pass) {
$keyPath = realpath($keyPath);
if (!file_exists($keyPath.'/WWDR.pem'))
die("Save the WWDR certificate as
$keyPath/WWDR.pem");
if (!file_exists($keyPath.'/passcertificate.pem'))
die("Save the pass certificate as

die("Save the pass certificate key as

$output = shell_exec("openssl smime -binary -sign". " -certfile '".$keyPath."/WWDR.pem'".

}
//signature debugging
//print(file_get_contents($this->workFolder."/signature"));
//create the zip bundle from the pass files
function writePassBundle() {
//1 generate the name for the .pkpass file
$passFile = $this->workFolder."/".$this->ID.".pkpass";
//2 create Zip class instance
$zip = new ZipArchive();
$success = $zip->open($passFile, ZIPARCHIVE::OVERWRITE);
if ($success!==TRUE) die("Can't create file $passFile");
//3 recurse over contents and build the list
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($this->workFolder),
RecursiveIteratorIterator::SELF_FIRST);
//4 add files to the archive
foreach($files as $name => $fileObject){
if (is_file($name) &&
substr($fileObject->getFileName(), 0, 1)!=".") {
$relativeName = str_replace($this->workFolder."/",
"",$name);
$zip->addFile($fileObject->getRealPath(), $relativeName);
}
}
//5 close the zip file
$zip->close();
//6 save the .pkpass file path and return it too
$this->passBundleFile = $passFile;
return $passFile;
}
//make new instance from a source folder
function __construct($path) {
assert(file_exists($path."/pass.json"));
$this->ID = uniqid();
$this->workFolder = sys_get_temp_dir()."/".$this->ID;
mkdir($this->workFolder);
assert(file_exists($this->workFolder));
$this->copySourceFolderFilesToWorkFolder($path);
$this->readPassFromJSONFile($this->workFolder."/pass.json");
}
//delete all auto-generated files in the temp folder
function cleanup()
{
//recurse over contents and delete files
$files = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($this->workFolder),
RecursiveIteratorIterator::CHILD_FIRST);
foreach($files as $name => $fileObject){
if (is_file($name)) {
unlink($name);
} else if (is_dir($name)) {
rmdir($name);
}
}
rmdir($this->workFolder);
}
//cleanup the temp folder on object destruction
function __destruct() {
$this->cleanup();
}
**/* THIS I ADDED AS A NEW FUNCTION TO PRESENT/DOWNLOAD */
function outputPassBundleAsWebDownload($fileName) {
//dump the generated pass to the browser

事情是通过不被呈现。它正在被正确创建，因为我使用fileName获得了屏幕上的回显。我在想什么？我从getPass.php调用输出函数并传入$ fileName。为什么它不工作？
