I'm able to upload a single using Webdriverio. But there are no options to upload multiple files from a single folder. Also I did tried searching for help on internet. There seems to be no discussions or topics to help. Please suggest how to upload multiple files from single folder using WebdriverIo.
Thanks!
The question here is: how multiple files are stored into input file tag in a HTML page?
HTML example:
<input type="file" id="test-file" name="input-file" multiple>
This function should be useful for single or multiple file, even for hidden or not displayed input:
const uploadFiles = async (filesPath, selector) => {
const files = Array.isArray(filesPath) ? filesPath : [filesPath];
const el = await $(selector);
await browser.execute((el) => el.style.display = 'block', el);
await el.waitForDisplayed();
await el.addValue(files.join('\n'));
}
await uploadFiles(['Users/username/etc.jpg', 'Users/username/etc.jpg'], '#test-file')
That's it.

I am trying to serve a static HTML file using the res.sendFile() method from my express.js server that is hosted on AWS Lambda using the Serverless framework. Assuming that I am trying to serve an HTML file from the directory src/views/users/index.html.
In deployment, this is the file path that I have tried to serve my HTML file from /var/task/src/views/users/vindex.html, but I keep getting the error Error: ENOENT: no such file or directory, stat '/var/task/src/views/users/index.html' when viewing the AWS Cloudwatch log.
app.use(express.static(__dirname));
path.resolve(__dirname, "./src/views/users/index.html");
This is the results I get when I run tree src locally:
Have anyone experienced this issue before, and have solved it? Thank you so much!
Well, after many grueling hours and trying many solutions, I have found a workaround to render the html content without actually needing to render a .html file.
I ended up making a helper method that returns a string of the html content and send the html content string using the res.send() method instead.
html helper function
export const htmlHelper = () => {
return `<html content goes here>`;
}
route method
app.get('/html', (_, res) => {
const htmlString = htmlHelper();
return res.send(htmlString);
})
I'm having troubles uploading doc and docx files, because I can't get the right type of file when converting it to base64. This is my input:
<input
accept=".pdf,.txt,.doc,.docx"
type="file"
(change)="onNativeInputFileSelect($event)"
#inputFile
hidden
/>
In my method I do this:
onNativeInputFileSelect(event) {
if (event.target.value) {
const file: File = event.target.files[0];
this.changeFile(file).then((base64: string): any => {
this.attachment.content= base64;
this.uploadFile(this.attachment);
});
}
}
then in "uploadFile" I send the file to server as base 64 string.
The changeFile methods is this:
changeFile(file) {
return new Promise((resolve, reject) => {
const reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = () => resolve(reader.result);
reader.onerror = (error) => reject(error);
});
}
This works fine for pdf or txt files, but when I upload .doc or .docx files I get this base64 string:
data:application/octet-stream;base64,0M8R4KGxGuEAA[...]
while for pdf I correctly have:
data:application/pdf;base64,JVBERi0xLjQKJeLjz9MKMS
This means that when I try to download the file I don't get the correct type, because I have application/octet-stream, and so I can't put the right extension to the file.
I've tried by passing to the accept property of input component this:
application/msword,application/pdf,text/plain,application/vnd.openxmlformats-officedocument.wordprocessingml.document
But nothing changed and the Window's file chooser suggested me only .pdf and .txt files
EDIT
This is a working stackblitz
I get "data:application/vnd.openxmlformats-officedocument.wordprocessingml.document;base64,UEsDBB[...]" for docx and "data:application/msword;base64,0M8R4KGxGuv[...]" for doc file.
I have a pdf URL and I want to open it using DocumentViewer. When I run code:
this._document.viewDocument(pdfUrl, 'application/pdf', options);
It is not opening PDF. I tried downloading PDF to my mobile and then open it. Please find code below:
transfer.download(downloadUrl, filename).then(entry => {
const url = entry.toURL();
if (this._plt.is('ios')) {
this._document.viewDocument(pdfUrl, 'application/pdf', options);
} else {
this._fileOpener.open(pdfUrl, 'application/pdf')
.then(() => console.log('File is opened'))
.catch(e => this.presentAlert('Error opening file', e));
}
});
I have tables and images in my PDF. When I ran above code I am not able to see HTML5 tables in the PDF.
I need help on how to open up PDF URL directly using DocumentViewer.
NOTE: I have seen a couple of post on StackOverflow suggesting to use InAppBrowser. I have a requirement where I need to display it as PDF.
I have read in https://github.com/sitewaerts/cordova-plugin-document-viewer,
that in android : Due to license restrictions in muPDF, the plugin dispatches to a separate (free) viewer app based on muPDF. If the viewer app is not yet installed, the user may be redirected to the google play app store.
https://play.google.com/store/apps/details?id=de.sitewaerts.cleverdox.viewer.
you may use other pdf plugins like

hope this helps
Following code works in Chrome (22.0) but not in Safari (6.0)
<!DOCTYPE html>
<html>
<head>
<script>
function onGo(e) {
var fr = new FileReader();
var file = document.getElementById("file").files[0];
fr.onload = function(e) {
var data = new Uint8Array(e.target.result);
var blob = new Blob([data], {type: 'audio/mpeg'});
var audio = document.createElement('audio');
audio.addEventListener('loadeddata', function(e) {
audio.play();
}, false);
audio.addEventListener('error', function(e) {
console.log('error!', e);
}, false);
audio.src = webkitURL.createObjectURL(blob);
};
fr.readAsArrayBuffer(file);
}
</script>
</head>
<body>
<input type="file" id="file" name="file" />
<input type="submit" id="go" onclick="onGo()" value="Go" />
</body>
</html>
In Safari, neither callback (loadeddata nor error) is called.
The content used is an mp3 file, which is normally played back with audio tag.
Is there any special care needed for Safari?
Many years later, I believe the example in the OP should work just fine. As long as you somehow set the mime type when creating the blob, like the OP does above with the type property of the options passed in:
new Blob([data], {type: 'audio/mpeg'});
You could also use a <source> element inside of an audio element and set the type attribute of the <source> element. I have an example of this here:
https://lastmjs.github.io/safari-object-url-test
And here is the code:
const response = await window.fetch('https://upload.wikimedia.org/wikipedia/commons/transcoded/a/ab/Alexander_Graham_Bell%27s_Voice.ogg/Alexander_Graham_Bell%27s_Voice.ogg.mp3');
const audioArrayBuffer = await response.arrayBuffer();
const audioBlob = new Blob([audioArrayBuffer]);
const audioObjectURL = window.URL.createObjectURL(audioBlob);
const audioElement = document.createElement('audio');
audioElement.setAttribute('controls', true);
document.body.appendChild(audioElement);
const sourceElement = document.createElement('source');
audioElement.appendChild(sourceElement);
sourceElement.src = audioObjectURL;
sourceElement.type = 'audio/mp3';
I prefer just setting the mime type of the blob when creating it. The <source> element src attribute/property cannot be updated dynamically.
I have the same problem, and I spend a couple days troubleshooting this already.
As pwray mentioned in this other post, Safari requires file extensions for media requests:
HTML5 Audio files fail to load in Safari
I tried to save my blob to a file, named it file.mp3 and Safari was able to load the audio that way, but after I renamed the file to have no extension (just "file"), it didn't load.
When I tried the url created from the blob in another tab in Safari:
url = webkitURL.createObjectURL(blob);
it download a file right away called "unknown", but when I tried the same thing in Chrome (also on Mac), it showed the content of the file in the browser (mp3 files start with ID3, then a bunch of non-readable characters).
I couldn't figure out yet how I could force the url made of blob to have an extension, because usually it looks like this:
blob:https://example.com/a7e38943-559c-43ea-b6dd-6820b70ca1e2
so the end of it looks like a session variable.
This is where I got stuck and I would really like to see a solution from some smart people here.
Thanks,
Steven
Sometimes, HTML5 audio can just stop loading without any apparent reason.
If you take a look to the Media Events (http://www.w3schools.com/tags/ref_eventattributes.asp) you´ll see an event called: "onStalled", the definition is "Script to be run when the browser is unable to fetch the media data for whatever reason" and it seems that it should be helpful for you.
Try listening for that event and reloading the file if necessary, with something like this:
audio.addEventListener('onstalled', function(e) {
audio.load();
}, false);
I hope it helps!
Just use source tag in audio.
<audio controls>
<source src="blob" type="blobType">
</audio>
I am unable to get images loaded on a webpage when in the LocalState directory.
Specifically, there appears to be a security issue when attempting to launch the webpage when the file path is referencing the LocalState directory.
The webpage DOES load with images when I right-click the html file and view it in the browser within Visual Studio.
I have changed the path of the src tag to: src="ms-appdata:///Local/Logo.jpeg"
It doesn't work.
Help me...
Example code
public static async Task Update(WebView webview, IStorageFile file) {
var html = await Windows.Storage.PathIO.ReadTextAsync(file.Path);
webview.NavigateToString(html);
}
The NavigateToString method doesn't work with tags that point to images in the LocalData folder. (as far as I recall anyway). In fact NavigateToString also breaks JavaScript and CSS links.
Images on Server
One solution, is to change your source to point to a network server instead of localdata. I'm not sure it that works for your app scenario though.
Images and HTML as content
The second choice is to add your html and image files as content to your app and use
WebView1.Navigate(new Uri("ms-appx-web:///assets/SampleHtmlPage.html"));
to load the HTML.
In Process HTTP Server
Here is a solution that uses a custom HTTP server in the app to handle the issues.
Loading Local HTML Content in Metro WebView (Windows 8)
Base 64 encoded image
Finally, there is another solution using Base64 encoding of your images in the LocalData folder.
internal async void MakeHtmlString()
{
StorageFile imageFile; // get image file here.
var html =
string.Format("<div><img src='data:image/png;base64,{0}'",
await GetImageBase64(imageFile));
}
internal async Task<string> GetImageBase64(StorageFile imageFile)
{
var imageStream = await imageFile.OpenAsync(FileAccessMode.Read);
var inputStream = imageStream.GetInputStreamAt(0);
var dataReader = new DataReader(inputStream);
var dataResults = await dataReader.LoadAsync((uint)imageStream.Size);
var bytes = new byte[dataResults];
dataReader.ReadBytes(bytes);
return Convert.ToBase64String(bytes);
}
This last approach works for images, but not for CSS files.
