问题描述
我有一个具有这样功能的网络服务
I have a webservice with a function like this
$app->get('/downloadPdf', function () use($app)
{
$log = 'example.pdf';
$res = $app->response();
$res['Content-Description'] = 'File Transfer';
$res['Content-Type'] = 'application/octet-stream';
$res['Content-Disposition'] ='attachment; filename=' . basename($log);
$res['Content-Transfer-Encoding'] = 'binary';
$res['Expires'] = '0';
$res['Cache-Control'] = 'must-revalidate';
$res['Pragma'] = 'public';
$res['Content-Length'] = filesize($log);
readfile($log);
});
使用Advanced Rest Client进行测试可以正常工作.
Testing it with Advanced Rest Client works fine..
问题是..我该如何从我的客户端调用所有标头等.
Question is .. how do i call it from my client with all the headers etc.
指定更多.我知道有很多关于如何通过将特定URL的完整地址插入curlopt_url中来下载特定文件的示例.我想要的是让网络服务决定要返回哪个文件...
To specify more. I know there are a lot of examples on how to download a specific file by inserting its url into the curlopt_url with the complete address to the file. What i want is to let the webservice decide which file to return...
谢谢
推荐答案
从来没有得到答案..所以!!!
Never got an answer .. so !!!
这就是我的工作方式....
This is how i made it work....
服务功能如下所示
$app->post('/downloadReport', 'authenticate', function() use ($app)
{
verifyRequiredParams(array('reportId'));
$body = $app->request()->getBody();
$params_str = urldecode($body);
$input = json_decode($params_str,true);
$report_id = $input['reportId'];
$db = new DbHandler();
$db->getReport($report_id);
$path = $db->getReportPdfPath($report_id);
$res = $app->response();
$res['Content-Description'] = 'File Transfer';
$res['Content-Type'] = 'application/octet-stream';
$res['Content-Disposition'] ='attachment; filename=' . basename($path);
$res['Content-Transfer-Encoding'] = 'binary';
$res['Expires'] = '0';
$res['Cache-Control'] = 'must-revalidate';
$res['Pragma'] = 'public';
$res['Content-Length'] = filesize($path);
readfile($path);
});
这样调用函数:
public function downloadReport($api_key,$id)
{
$curl_post_data = array('reportId' => $id);
$headers = array('Content-type: application/json','Authorization: '.$api_key,);
$fp = fopen (dirname(__FILE__) . '/localfile.tmp', 'w+');//This is the file where we save the information
$curl = curl_init(DONWLOAD_REPORT);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($curl_post_data));
curl_setopt($curl, CURLOPT_USERPWD, $api_key);
$file = curl_exec($curl);
if ($file === false)
{
$info = curl_getinfo($curl);
curl_close($curl);
die('error occured during curl exec. Additioanl info: ' . var_export($info));
}
curl_close($curl);
header('Content-type: ' . 'application/octet-stream');
header('Content-Disposition: ' . 'attachment; filename=report.pdf');
echo $file;
}
