How to perform file Upload and download in Selendroid with Java? I'm testing the mobile version of a site.. I did upload and download using Selenium webdriver, and it was working perfectly. Please give me a solution for upload/download in Selendroid.
public void startDriver() throws InvalidFileFormatException, IOException{
FirefoxProfile profile = new FirefoxProfile();
String path1 = "C:\\Downloads_sel";
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", path1);
System.out.println(path1);
profile.setPreference("browser.download.alertOnEXEOpen", false);
// profile.setPreference("browser.helperApps.neverAsksaveToDisk",
// "application/x-msexcel,application/excel,application/x-excel,application/excel,application/x-excel,application/excel,application/vnd.ms-excel,application/x-excel,application/x-msexcel,application/pdf,application/xml");
profile.setPreference(
"browser.helperApps.neverAsk.saveToDisk",
"application/msword, application/csv, application/ris, text/csv, image/png, application/pdf, text/html, text/plain, application/zip, application/x-zip, application/x-zip-compressed, application/download, application/octet-stream");
profile.setPreference("browser.download.manager.showWhenStarting",
false);
profile.setPreference("browser.download.manager.focusWhenStarting",
false);
profile.setPreference("browser.helperApps.alwaysAsk.force", false);
profile.setPreference("browser.download.manager.alertOnEXEOpen", false);
profile.setPreference("browser.download.manager.closeWhenDone", false);
profile.setPreference("browser.download.manager.showAlertOnComplete",
false);
profile.setPreference("browser.download.manager.useWindow", false);
profile.setPreference("browser.download.manager.showWhenStarting",
false);
profile.setPreference(
"services.sync.prefs.sync.browser.download.manager.showWhenStarting",
false);
// ..i commented this line..but it didnt work
profile.setPreference("pdfjs.disabled", true);
driver = new FirefoxDriver(profile);
driver.manage().window().maximize();
driver.get(URL1);
System.out.println("gotURL");
}
This was my code to perform a download in selenium webdriver..and how to do the same in selendroid

i can't really find a way to download a 100mb zip file from the server to the client and also show the progress while downloading. So how will this look for a normal api controller i can add to my server-side project? if lets say i have 3 files i want to download at 50mb each.
i have tried using JSInterop like this, but this is not showing the progress of the file download, and how will i do if i want to download 3 seperate files at the same time?
try
{
//converting file into bytes array
var dataBytes = System.IO.File.ReadAllBytes(file);
await JSRuntime.InvokeVoidAsync(
"downloadFromByteArray",
new
{
ByteArray = dataBytes,
FileName = "download.zip",
ContentType = "application/force-download"
});
}
catch (Exception)
{
//throw;
}
JS:
function downloadFromByteArray(options: {
byteArray: string,
fileName: string,
contentType: string
}): void {
// Convert base64 string to numbers array.
const numArray = atob(options.byteArray).split('').map(c => c.charCodeAt(0));
// Convert numbers array to Uint8Array object.
const uint8Array = new Uint8Array(numArray);
// Wrap it by Blob object.
const blob = new Blob([uint8Array], { type: options.contentType });
// Create "object URL" that is linked to the Blob object.
const url = URL.createObjectURL(blob);
// Invoke download helper function that implemented in
// the earlier section of this article.
downloadFromUrl({ url: url, fileName: options.fileName });
// At last, release unused resources.
URL.revokeObjectURL(url);
}
UPDATE:
if im using this code, it will show me the progress of the file. But how can i trigger it from my code? This way does not do it. But typing the url does.
await Http.GetAsync($"Download/Model/{JobId}");
Controller
[HttpGet("download/model/{JobId}")]
public IActionResult DownloadFile([FromRoute] string JobId)
{
if (JobId == null)
{
return BadRequest();
}
var FolderPath = $"xxxx";
var FileName = $"Model_{JobId}.zip";
var filePath = Path.Combine(environment.WebRootPath, FolderPath, FileName);
byte[] fileBytes = System.IO.File.ReadAllBytes(filePath);
return File(fileBytes, "application/force-download", FileName);
}
UPDATE 2!
i have got it download with progress and click with using JSInterop.
public async void DownloadFiles()
{
//download all selectedFiles
foreach (var file in selectedFiles)
{
//download these files
await JSRuntime.InvokeAsync<object>("open", $"Download/Model/{JobId}/{file.Name}", "_blank");
}
}
Now the only problem left is.. it only downloads the first file out of 3.
When I open big files(document) in third party app above 30 mb file app gets stuck - can anyone help me out of this?
I use dependency service from Xamarin.Forms for opening the file and in Android I have implemented this code:
public void OpenFile(File fileToOpen)
{
var uri = Android.Net.Uri.FromFile(fileToOpen);
var intent = new Intent();
var mime = IOUtil.GetMimeType(uri.ToString());
intent.SetAction(Intent.ActionView);
intent.SetDataAndType(uri, mime);
intent.SetFlags(ActivityFlags.NewTask);
_context.StartActivity(intent);
}
If your android phone's system version is android 7.0.
You need to notice that,in 7.0, Android has enhanced access to files. File access must be fileProvider.
fileType = fileType.toLowerCase();
Uri uri = null;
Intent intent = new Intent("android.intent.action.VIEW");
intent.addCategory("android.intent.category.DEFAULT");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", new File(filePath));
}else {
uri = Uri.fromFile(new File(filePath));
}
intent.setDataAndType(uri, getMap(fileType));
context.startActivity(intent);
However,if your three party app does not support the way file permissions are turned on 7.0, it still will error.
So,you can try this rogue method(^-^).Skip its verification and continue using the 6.0 method
public static void openFileEx(String filePath, String fileType, Context context) {
Intent intent = new Intent(Intent.ACTION_VIEW);
// Judging the version is greater than or equal to 7.0
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
StrictMode.setVmPolicy(builder.build());
}
Uri data = Uri.fromFile(new File(filePath));
intent.setDataAndType(data, getMap(fileType));
Toast.makeText(context, "uri:" + data.toString(), Toast.LENGTH_SHORT).show();
context.startActivity(intent);
}
More info about code's getMap method
public static String getMap(String key) {
Map<String, String> map = new HashMap<String, String>();
map.put("rar", "application/x-rar-compressed");
map.put("jpg", "image/jpeg");
map.put("zip", "application/zip");
map.put("pdf", "application/pdf");
map.put("doc", "application/msword");
map.put("docx", "application/msword");
map.put("wps", "application/msword");
map.put("xls", "application/vnd.ms-excel");

map.put("", "*/*");
return map.get(key.toLowerCase());
}
What should I do to be able read several consecutive pages from a web site? I am working with CefSharp WinForms and my problem is: In the loop I can get the source from the first page, but any other page gives only part of the source.
I use settings:
CefSettings settings = new CefSettings();
settings.CefCommandLineArgs.Add("enable-media-stream", "1");
settings.CefCommandLineArgs.Add("no-proxy-server", "1");
settings.CefCommandLineArgs.Add("disable-web-security", "1");
settings.CefCommandLineArgs.Add("allow-file-access-from-files", "1");
Cef.Initialize(settings);
And use
public static Task LoadPageAsync(this IWebBrowser browser, string address = null)
{
var tcs = new TaskCompletionSource<bool>();
EventHandler<LoadingStateChangedEventArgs> handler = null;
handler = (sender, args) =>
{
//Wait for while page to finish loading not just the first frame
if (!args.IsLoading)
{
browser.LoadingStateChanged -= handler;
tcs.TrySetResult(true);
}
};
browser.LoadingStateChanged += handler;
if (!string.IsNullOrEmpty(address))
{
browser.Load(address);
}
return tcs.Task;
}
I made a feedback project. I made it on ASP.NET MVC 5 it also has crystal reports. reports were working fine, but suddenly they stopped to work. I don't what happened with them. but since last week I tried hard to find solution but unfortunately could not get the right one who solved the solution. I downloaded different run times but all went vain. this is the bottom line of error.
"Method not found: 'CrystalDecisions.ReportAppServer.DataDefModel.PropertyBag CrystalDecisions.ReportAppServer.ReportDefModel.ISCRExportOptions.get_ExportOptionsEx()'"
this is the code:
public CrystalReportFeedback UserFeedbackDateWise(FeedbackReport be){
if (Session["CurrentUser"] != null && Convert.ToInt32(Session["User_Id"]) != 0)
{
string reportPath = Path.Combine(Server.MapPath("~/Reports"), "UserFeedbackReport.rpt");
if (ModelState.IsValid)
{
be.FromDate = Convert.ToDateTime(TempData["UserFromDate"]);
be.ToDate = Convert.ToDateTime(TempData["UserToDate"]);
be.User_Id = Convert.ToInt32(Session["User_Id"]);
}
return new CrystalReportFeedback(reportPath, be);
}
else
{
return null;
//new CrystalReportFeedback(reportPath, be);
}
}
Init of the report :
public CrystalReportFeedback(string reportPath, FeedbackReport be)//, object dataSet)
{
//int[] array;
string strConnect = Convert.ToString(System.Configuration.ConfigurationManager.ConnectionStrings["TSC"]);
SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(strConnect);
string _username = builder.UserID;
string _pass = builder.Password;
string _server = builder.DataSource;
string _database = builder.InitialCatalog;
ReportDocument reportDocument = new ReportDocument();
//
reportDocument.Load(reportPath);
reportDocument.SetDatabaseLogon(_username, _pass, _server, _database);
if (be.Region_Id != 0)
{
reportDocument.SetParameterValue("#Region_Id", be.Region_Id);
}
if (be.User_Id != 0)
{
reportDocument.SetParameterValue("#User_Id", be.User_Id);
}
reportDocument.SetParameterValue("#FromDate", be.FromDate);
reportDocument.SetParameterValue("#ToDate", be.ToDate);
//reportDocument.ExportToDisk(ExportFormatType.PortableDocFormat, "C:\report.pdf");
_contentBytes = StreamToBytes(reportDocument.ExportToStream(ExportFormatType.PortableDocFormat));
}
Export method :
public override void ExecuteResult(ControllerContext context)
{
var response = context.HttpContext.ApplicationInstance.Response;
response.Clear();
response.Buffer = false;
response.ClearContent();
response.ClearHeaders();
response.Cache.SetCacheability(HttpCacheability.Public);
response.ContentType = "application/pdf";
using (var stream = new MemoryStream(_contentBytes))
{
stream.WriteTo(response.OutputStream);
stream.Flush();
}
}
private static byte[] StreamToBytes(Stream input)
{
byte[] buffer = new byte[16 * 1024];
using (MemoryStream ms = new MemoryStream())
{
int read;
while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
{
ms.Write(buffer, 0, read);
}
return ms.ToArray();
}
}
Hope that I will get my solution at earliest.
this is modified code:
[HttpGet]
public FileResult UserFeedbackDateWise(FeedbackReport be)
{
if (Session["CurrentUser"] != null && Convert.ToInt32(Session["User_Id"]) != 0)
{
string reportPath = Path.Combine(Server.MapPath("~/Reports"), "UserFeedbackReport.rpt");
if (ModelState.IsValid)
{
be.FromDate = Convert.ToDateTime(TempData["UserFromDate"]);
be.ToDate = Convert.ToDateTime(TempData["UserToDate"]);
be.User_Id = Convert.ToInt32(Session["User_Id"]);
}
string strConnect = Convert.ToString(System.Configuration.ConfigurationManager.ConnectionStrings["TSC"]);
SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(strConnect);
string _username = builder.UserID;
string _pass = builder.Password;
string _server = builder.DataSource;
string _database = builder.InitialCatalog;
ReportDocument reportDocument = new ReportDocument();
//
reportDocument.Load(reportPath);
reportDocument.SetDatabaseLogon(_username, _pass, _server, _database);
if (be.Region_Id != 0)
{
reportDocument.SetParameterValue("#Region_Id", be.Region_Id);
}
if (be.User_Id != 0)
{
reportDocument.SetParameterValue("#User_Id", be.User_Id);
}
reportDocument.SetParameterValue("#FromDate", be.FromDate);
reportDocument.SetParameterValue("#ToDate", be.ToDate);
Stream stream = reportDocument.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
//Here i have my stream with my pdf report, i just create a new FileStreamResult and return it to my client like that :
FileStreamResult myfile = new FileStreamResult(stream, "application/pdf");
return myfile;
//new CrystalReportFeedback(reportPath, be);
}
else
{
return null;
//new CrystalReportFeedback(reportPath, be);
}
}
This isn't a coding issue, it's a runtime issue. The version of the crystal runtime or the bitness of your application.
One thing to try first is to upgrade both your development version and ensure you're running the same version in production. See https://apps.support.sap.com/sap/support/knowledge/public/en/2148492 for more details
It says:
Compile your application either to 'X86 mode' or 'X64 mode'
Install the particular versions of runtimes on deployment machine.
i.e. If the application is compiled as 32 bit, then install the 32bit runtimes.
I'll try my best to help you exporting your report, but your post is not very clear. For your next post try to be very specific and provide as much information as you can.
I currently made a MVC project and export a crystalreport report from my controller to my client.
I think that your ExecuteResult method can work, but working with the httpcontext is useless, Crystalreport and .NET provide some useful methods to do the same.
So i'll show you how i create and export my report so you can copy / paste and modify your code.
Here is my controller method, called from a button :
[HttpGet]
public FileResult InitReport()
{
//I create my report here
FileImportReport rptH = new FileImportReport();
// Some configuration on the report, datasource, databaselogon .. etc
...
//
//Then I export my report to a pdf stream like that :
Stream stream = rptH.ExportToStream(CrystalDecisions.Shared.ExportFormatType.PortableDocFormat);
//Here i have my stream with my pdf report, i just create a new FileStreamResult and return it to my client like that :
FileStreamResult myfile = new FileStreamResult(stream, "application/pdf");
return myfile;
}
My method is called from a button but it can work like you want, or the file can be saved in any known path.
You can test to reproduce my code, in your CrystalReportFeedback method use my code with your reportDocument object, you don't need to use your StreamToBytes method.

I have been looking into phantomJS and looks like it could be a great tool to use generating PDFs. I wonder if anyone have successfully used it for their .NET applications.
My specific question is: how would you use modules like rasterize.js on the server, receive requests and send back generated pdfs as a response.
My general question is: is there any best practice for using phantomJS with .NET Applications. What would be the best way to achieve it?
I am fairly new in .NET World and I would appreciate the more detailed answers. Thanks everyone. :)
I don't know about best practices, but, I'm using phantomJS with no problems with the following code.
public ActionResult DownloadStatement(int id)
{
string serverPath = HttpContext.Server.MapPath("~/Phantomjs/");
string filename = DateTime.Now.ToString("ddMMyyyy_hhmmss") + ".pdf";
new Thread(new ParameterizedThreadStart(x =>
{
ExecuteCommand("cd " + serverPath + #" & phantomjs rasterize.js http://localhost:8080/filetopdf/" + id.ToString() + " " + filename + #" ""A4""");
})).Start();
var filePath = Path.Combine(HttpContext.Server.MapPath("~/Phantomjs/"), filename);
var stream = new MemoryStream();
byte[] bytes = DoWhile(filePath);
return File(bytes, "application/pdf", filename);
}
private void ExecuteCommand(string Command)
{
try
{
ProcessStartInfo ProcessInfo;
Process Process;
ProcessInfo = new ProcessStartInfo("cmd.exe", "/K " + Command);
ProcessInfo.CreateNoWindow = true;
ProcessInfo.UseShellExecute = false;
Process = Process.Start(ProcessInfo);
}
catch { }
}
public ViewResult FileToPDF(int id)
{
var viewModel = file.Get(id);
return View(viewModel);
}
private byte[] DoWhile(string filePath)
{
byte[] bytes = new byte[0];
bool fail = true;
while (fail)
{
try
{
using (FileStream file = new FileStream(filePath, FileMode.Open, FileAccess.Read))
{
bytes = new byte[file.Length];
file.Read(bytes, 0, (int)file.Length);
}
fail = false;
}
catch
{
Thread.Sleep(1000);
}
}
System.IO.File.Delete(filePath);
return bytes;
}
Here is the action flow:
The user clicks on a link to DownloadStatement Action. Inside there, a new Thread is created to call the ExecuteCommand method.
The ExecuteCommand method is responsible to call phantomJS. The string passed as an argument do the following.
Go to the location where the phantomJS app is and, after that, call rasterize.js with an URL, the filename to be created and a print format. (More about rasterize here).
In my case, what I really want to print is the content delivered by the action filetoupload. It's a simple action that returns a simple view. PhantomJS will call the URL passed as parameter and do all the magic.
While phantomJS is still creating the file, (I guess) I can not return the request made by the client. And that is why I used the DoWhile method. It will hold the request until the file is created by phantomJS and loaded by the app to the request.
If you're open to using NReco.PhantomJS, which provides a .NET wrapper for PhantomJS, you can do this very succinctly.
public async Task<ActionResult> DownloadPdf() {
var phantomJS = new PhantomJS();
try {
var temp = Path.Combine(Path.GetTempPath(),
Path.ChangeExtension(Path.GetRandomFileName(), "pdf")); //must end in .pdf
try {
await phantomJS.RunAsync(HttpContext.Server.MapPath("~/Scripts/rasterize.js"),
new[] { "https://www.google.com", temp });
return File(System.IO.File.ReadAllBytes(temp), "application/pdf");
}
finally {
System.IO.File.Delete(temp);
}
}
finally {
phantomJS.Abort();
}
}
Here's some very basic code to generate a PDF using Phantom.JS but you can find more information here: https://buttercms.com/blog/generating-pdfs-with-node
var webPage = require('webpage');
var page = webPage.create();
page.viewportSize = { width: 1920, height: 1080 };
page.open("http://www.google.com", function start(status) {
page.render('google_home.pdf, {format: 'pdf', quality: '100'});
phantom.exit();
});
