存储在服务器上生成的PDF文件 [英] Storing generated PDF files on the server
问题描述
使用 jsPDF
插件,我创建一个的.pdf
文件基础上产生一个按钮点击下载。我想将文件保存到启动下载我的服务器来代替。因此,当单击该按钮,我想将文件保存在:
Using the jsPDF
plugin, I am creating a .pdf
file and generating a download based on a button click. I would like to save the file onto my server instead of initiating the download. So when the button is clicked I would like the file to be saved in :
/tmp/uploads/pdf/example.pdf
我知道我需要必须使用 Jquery.Ajax
发布文件到服务器。然而,看着文件,我没有看到的.pdf
作为一种数据类型的支持。
I am aware I need have to use Jquery.Ajax
to post the file to the server. However, looking at the documentation and I didn't see any support for .pdf
as a datatype.
我的code:
$(document).on("click", "#PDF", function () {
var table = document.getElementById("result");
var tbl = window.sessionStorage.getItem("tbl");
var cols = [],
data = [];
function html() {
var doc = new jsPDF('p', 'pt');
var res = doc.autoTableHtmlToJson(table, true);
doc.autoTable(res.columns, res.data);
doc.save( tbl+".pdf");
}
html();
});
在此基础上 XML文档,节省例如
我尝试以下
Based on this xml document saving example I tried the following:
var pdfDocument = doc.save( tbl+".pdf");
var pdfRequest = $.ajax({
url: "/tmp/uploads/pdf",
processData: false,
data: pdfDocument
});
该下载的,而不是将其保存的文件。我如何保存文件?
This downloaded the file instead of saving it. How can I save the file?
推荐答案
我管理这个用修复 FORMDATA()
,这里是我如何做的:
I managed to fix this using FormData()
, here's how I did it:
$(document).on("click", "#PDF", function () {
var table = document.getElementById("result");
var cols = [],
data = [];
function html() {
var doc = new jsPDF('p', 'pt');
var res = doc.autoTableHtmlToJson(table, true);
doc.autoTable(res.columns, res.data);
var pdf =doc.output(); //returns raw body of resulting PDF returned as a string as per the plugin documentation.
var data = new FormData();
data.append("data" , pdf);
var xhr = new XMLHttpRequest();
xhr.open( 'post', 'upload.php', true ); //Post to php Script to save to server
xhr.send(data);
}
html();
});
upload.php的
if(!empty($_POST['data'])){
$data = $_POST['data'];
$fname = "test.pdf"; // name the file
$file = fopen("testa/pdf/" .$fname, 'w'); // open the file path
fwrite($file, $data); //save data
fclose($file);
} else {
echo "No Data Sent";
}
关键的部分是 VAR PDF = doc.output();
要获取原始PDF数据。
The key part being var pdf =doc.output();
where you want to get the raw pdf data.
