I'm running pupeteer in a container on Azure and trying to download a file.
The file saves correctly in the container, even in the correct folder defined in the pupeteer sharp setup. However, the same folder is created on my local machine, but the file is never downloaded to it.
I'm using the latest version of pupeteer sharp and a pretty recent docker image for pupeteer and chrome.
I've tried, setting the downloadpath of the pupeteer setup
`
await page.Client.SendAsync("Page.setDownloadBehavior", new
{
behavior = "allow",
downloadPath = _downloadDirectory,
});
`
I've also tried intercepting the response after clicking on the download button, but I keep getting a "unable to read response body" error when reading the buffer to write to disk.
`
var responseData = await GetResponseWithFile(page);
var contentDisposition = responseData.Headers["content-disposition"];
var fileName = contentDisposition.Split(";")[1].Split("=")[1];
var buff = await responseData.BufferAsync();
File.WriteAllBytes(_downloadDirectory + $"\\{fileName}", buff);

i want to upload Image to Dropbox. This code is worked but i want fileToUpload to be is a web URL because images is a Web Server. i know i can download every Images step by step. But this is a loss of performance. If i write a WebUrl in the fileToUpload. i see the exception. For Example:
fileToUpload = "https:\upload.wikimedia.org\wikipedia\commons\5\51\Small_Red_Rose.JPG"
The Exception:
C:\Users\LENOVO****\bin\Debug\net6.0\https:\upload.wikimedia.org\wikipedia\commons\5\51\Small_Red_Rose.JPG
*** - is a local folder name
i want to upload image to dropbox from Web
The UploadAsync method requires that you supply the data of the file to upload directly, as you are doing in your example by retrieving the file data from the local filesystem using File.ReadAllBytes.
If you want to upload a file to Dropbox directly from a URL without downloading it to your local filesystem first, you should instead use the SaveUrlAsync method.
I have a simple web app which allows downloading files.
The file gets downloaded correctly, however the browser never indicates the amount of data received (i.e. the progress).
It just keeps showing 0.1 MB until suddenly the file is downloaded.
Download action is implemented as follows - for now, simply open-read the local file and return the stream as File result.
public async Task<IActionResult> Download(string id)
{
var project = await this.service.GetById(id).ConfigureAwait(false);
if (project == null)
{
return this.NotFound($"Project [{id}] does not exist");
}
var file = new FileInfo(project.DownloadLocation);
this.Response.ContentLength = file.Length;
return this.File(file.OpenRead(), "application/octet-stream", file.Name);
}
The download is triggered by a simple action link:
<dd class="project-path">#Html.ActionLink("Here", "Download", "Download", new { id = Model.Id})</dd>
Any idea why Chrome/Firefox never shows the download progress?
Your code should do the trick. You should try it with a larger file (eg:200mb)? It might be the reason time to calculate ETA taking more than downloading it in a local development environment.
Ultimately I'm trying to upload a document from the user's file system via MVC .NET web site to Google Drive, which utilizes a service account.
I'm not sure if I'm implementing the appropriate design to accomplish the upload but I am getting hung up on the path of the file to be uploaded.
Web
#Html.TextBox("file", "file", new { type = "file", id = "fileUpload" })
Controller
public ActionResult GoogleDriveList(GoogleDrivePageVM vm, HttpPostedFileBase file)
File _file = new File();
var _uploadFile = System.IO.Path.GetFileName(file.FileName);
byte[] byteArray = System.IO.File.ReadAllBytes(_uploadFile);
Error occurs on the ReadAllBytes statement. It could not find file 'C:\Program Files (x86)\IIS Express\Map of Universe.txt'. The file name is correct but the path is not.
byte[] byteArray = System.IO.File.ReadAllBytes(_uploadFile);
System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
... Google Drive file stuff goes here
Then upload the file from the stream.
FilesResource.InsertMediaUpload request = _service.Files.Insert(body, stream, body.MimeType);
request.Upload();
So, am I going down the right path using the HTML file helper? And if so, what's the trick to get the path to work correctly? Also, I want to be able to support file sizes up to 500 MB (if that makes a difference).
If your getting the filename from a user selected windows file explorer dialog, then you shouldn't be using the below as will just strip out the filename without the path into your upload file variable and I am assuming that bogus path is where your're running the code from, so ReadAllBytes is trying to read from that path with the filename
var _uploadFile = System.IO.Path.GetFileName(file.FileName)
just change so it has that full path and filename you need to use in ReadAllBytes
var _uploadFile = file.FileName
I'm quite new to using RestSharp and I've got a question that I can't find an answer to here on SO.
I've have this situation where I must download a csv-file and output the file directly in the browser. The following code illustrates how to download a file and save it to a certain path on disc.
string tempFile = Path.GetTempFileName();
using (var writer = File.OpenWrite(tempFile))
{
var client = new RestClient(baseUrl);
var request = new RestRequest("Assets/LargeFile.7z");
request.ResponseWriter = (responseStream) => responseStream.CopyTo(writer);
var response = client.DownloadData(request);
}
I want to download the csv-file and directly output the result as a download file in the browser. You know, like in Chrome the file you download will be displayed in the left bottom corner of your browser.
Can this be done using RestSharp? And if so, how? Got an example? Please share it. ;-)
Thanx!
I'm using a webview to display certain data in my windows 8 app. I would like to user an include to a local js file as well as use locally stored images.
Is this possible?
I haven't had any luck by putting the local path where the files are located.
According to WebView documentation you can only reference other files using the ms-appx-web protocol, i.e. to load the files stored in Windows.ApplicationModel.Package.Current.InstalledLocation, meaning that they need to be distributed as content along with your application. The control doesn't support ms-appdata protocol for security reasons, i.e. you can't open files stored Windows.Storage.ApplicationData.Current.LocalFolder Windows.Storage.ApplicationData.Current.RemoteFolder or Windows.Storage.ApplicationData.Current.TempFolder where you'd need to put them if you were generating or downloading them at runtime.
In JavaScript apps WebView is a bit more flexible: it does support ms-appdata protocol as well, but only for media files such as images. It cannot open any potentially executable code, such as script or CSS.
If you want to open some local .html file or atc. you should download it in InstalledLocation folder. If you haven't option to create a new file you can just use file.CopyAsync(htmlFolder, fname + ".html");
For example I create some .html file:
StorageFolder htmlFolder = await Windows.ApplicationModel.Package.Current.InstalledLocation.CreateFolderAsync(#"HtmlFiles", CreationCollisionOption.GenerateUniqueName);
IStorageFile file = await htmlFolder .CreateFileAsync(fname + ".html", CreationCollisionOption.GenerateUniqueName);
and than I can easily open this .html file with or without FileOpenPicker:
var fop = new FileOpenPicker();
fop.FileTypeFilter.Add(".html");
var file = await fop.PickSingleFileAsync();
if (file != null)
{
string myPath = file.Path.Substring(file.Path.IndexOf("HtmlFiles"));
myWebview.Navigate(new Uri("ms-appx-web:///" + myPath));
}
And don't forget - just only from InstalledLocation you can open it with ms-appx-web:///
If the WebView is IE10 based, FIleReader may be what you are looking for. Here is a snippet of code that I use on an image ipload page to show images in a page when they are selected via a File Open dialog:
$('input:file').each(function(index, evt){
if(index===0)
{
var files = evt.files;
for(var i=0;i<files.length;i++)
{
if(files[i].name===filename)
{
var reader = new FileReader();
reader.onload=(function(theFile){
return function(e){
var line= uploader.fineUploader('getItemByFileId',id);
if(line!=undefined)
$(line).append('<img class="fileimage" id="fileImage-' + id + '" src="'+e.target.result+'" />');
};
})(files[i]);
reader.readAsDataURL(files[i]);
break;
}
}
}
I hope this points you in the right direction!
