I may be asking the basics just now, sorry.
I want to convert Uint8Array back to a file and save it in db.
Is there anyone who can help me?
document.getElementById('upload_0').onchange = function(event) {
var ext = $('[name=upload_0]').val().split('.').pop().toLowerCase();
var file = event.target.files[0];
var fileReader = new FileReader();
fileReader.onload = async function() {
var typedarray = new Uint8Array(this.result);
const pdfSrcDoc = await PDFLib.PDFDocument.load(typedarray);
const pdfNewDoc = await PDFLib.PDFDocument.create();
const pages = await pdfNewDoc.copyPages(pdfSrcDoc, [0,1,2]);
pages.forEach((page) => pdfNewDoc.addPage(page));
const newpdf = await pdfNewDoc.save();
download(newpdf, "sample.pdf", "application/pdf");
}
-> download(newpdf, "sample.pdf", "application/pdf");
I want to convert this part into a file, not download it, and save it in db.
Also, I want to save the file name as the original name.
Can you tell me what I want to know?
Thank you.
In this method, the output is as follows:
I/flutter ( 2928): 200
I/flutter ( 2928): null
I/flutter ( 2928): [Instance of 'Images']
This is causing snapshot.data to be null in my FutureBuilder as well.Any Idea why is this happening?
Future<List<Images>> getData( File f ) async {
List<Images> list;
// String link = "https://clothest.herokuapp.com/";
String link ="https://us-central1-velvety-rookery-274308.cloudfunctions.net/function-1";
var stream = new http.ByteStream(DelegatingStream.typed(f.openRead()));
var length = await f.length();
var postUri = Uri.parse(link);
var request = new http.MultipartRequest("POST", postUri);
var multipartFileSign = new http.MultipartFile('File', stream, length,
filename: basename(f.path));
request.files.add(multipartFileSign);
request.headers.addAll({"content-type": "application/json"});
var response = await request.send();
print(response.statusCode); //200 OK
if (response.statusCode == 200){
response.stream.transform(utf8.decoder).listen((value) {
var data = json.decode(value);
var rest = data["Items"] as List;
list = rest.map<Images>((json) => Images.fromJson(json)).toList();
print(list.toString());
});
}
print(list.toString());
return list;
}
So I managed to solve this problem by using another package instead of the HTTP package. Dios package is the best regarding HTTP requests. Updated code:
Future<List<Images>> getData( File f ) async {
List<Images> lst=[];
String link ="https://us-central1-velvety-rookery-274308.cloudfunctions.net/function-1";
Dio dio = new Dio();
FormData formdata = new FormData(); // just like JS
formdata.add('File', new UploadFileInfo(f, basename(f.path)));
await dio.post(link, data: formdata, options: Options(
method: 'POST',
responseType: ResponseType.JSON // or ResponseType.JSON
)).then((response) {
print(response);
if(response.statusCode==200){ //OK
var responseBody = response.data; //Map
var rest = responseBody["Items"] as List;
//print(rest);
lst = rest.map<Images>((json) => Images.fromJson(json)).toList(); //instances of 'Images' object
//print(lst);
}
}
).catchError((error) => print(error));
return lst;
Since I am sending lots of data with the request, I have to use renderAsync to use POST. When the stream came back, I use the following JS code to open it
jsreport.renderAsync(request).then(function(arrayBuffer) {
window.open("data:application/pdf;base64," + arrayBuffer
)};);
But then the error showed. Is there alternative way to do it?
This seems to work
<script>
jsreport.renderAsync(request).then(function(response) {
var uInt8Array = new Uint8Array(response);
var i = uInt8Array.length;
var binaryString = new Array(i);
while (i--)
{
binaryString[i] = String.fromCharCode(uInt8Array[i]);
}
var data = binaryString.join('');
var base64 = window.btoa(data);
window.open("data:application/pdf;base64, " + base64);
})
</script>
How to send file in QML. I tried something like:
var pathImage = "file:assets-library:/asset/asset.JPG%3Fid=0EEAFD08-5878-45D1-9045-025FD5CAB907&ext=JPG"
var request = new XMLHttpRequest();
var request_url = API_URL + '?method=postImage';
request.open('POST', request_url);
var params = "image=" + pathImage;
request.send(params);
But it doesn't send file.
How to send file in QML without C-code?
I'm able to create the JSZip object in my code, but I'm having trouble saving that to local storage in my windows 8 app. The examples I'm able to find set the browser's location.href to trigger a download, which isn't really an option for me.
I've included my code below. The zip file I end up with is invalid and can't be opened. Any help would be appreciated.
For reference: JSZip
function _zipTest() {
var dbFile = null;
var zipData = null;
Windows.Storage.StorageFile.getFileFromPathAsync(config.db.path)
.then(function (file) {
dbFile = file;
return Windows.Storage.FileIO.readBufferAsync(file);
})
.then(function (buffer) {
//Read the database file into a byte array and create a new zip file
zipData = new Uint8Array(buffer.length);
var dataReader = Windows.Storage.Streams.DataReader.fromBuffer(buffer);
dataReader.readBytes(zipData);
dataReader.close();
var localFolder = Windows.Storage.ApplicationData.current.localFolder;
return localFolder.createFileAsync(dbFile.displayName.concat('.zip'), Windows.Storage.CreationCollisionOption.replaceExisting)
})
.then(function (file) {
//Write the zip data to the new zip file
var zip = new JSZip();
zip.file(dbFile.displayName, zipData);
var content = zip.generate();
return Windows.Storage.FileIO.writeTextAsync(file, content);
});
}
you can do something on these lines. This code seem to generate valid .zip file in the temp folder.
var zip = new JSZip();
var storage = Windows.Storage;
storage.StorageFile.getFileFromApplicationUriAsync(new Windows.Foundation.Uri('ms-appx:///images/logo.png')).then(function ongetfile(file)
{
var blob = MSApp.createFileFromStorageFile(file);
var url = URL.createObjectURL(blob, { oneTimeOnly: true });
return WinJS.xhr({ url: url, responseType: 'arraybuffer' });
}).then(function onreadbuffer(req)
{
var b = req.response;
zip.file('logo.png', b);
return storage.ApplicationData.current.temporaryFolder.createFileAsync('a.zip', storage.CreationCollisionOption.replaceExisting);
}).then(function onnewfile(out)
{
var content = zip.generate({ type: 'uint8array' });
return storage.FileIO.writeBytesAsync(out, content);
}).then(null, function onerror(error)
{
// TODO: error handling
});
