I got access to .txt file located on OneDrive by changing it's path end from =***** to =download. Then I'm trying to download this file using the following code:
string fileName = Android.OS.Environment.DirectoryDownloads + "/textfile.txt";
WebClient web = new WebClient();
web.UseDefaultCredentials = true;
web.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;
web.DownloadFile(uslugiPath, fileName);
As a result I get this Unauthorized.Access exception (access to Downloads is denied).
I checked [This] (Xamarin : Android : System.UnauthorizedAccessException: Access to the path is denied) topic and many others but I didn't find solution.
Permissins.CheckStatusAsync<Permissions.StorageREad> as a result gives "Granted".
API 29
in my case the solution was use the path defined
var fileName = global::Android.OS.Environment.ExternalStorageDirectory.AbsolutePath

I trying to save a PDF file, previously obtained from a REST WS as byte[] array.
byte[] response = await caller.DownloadFile(url);
string documentPath = FileSystem.CacheDirectory;
string fileName = "downloadfile.pdf";
string path = Path.Combine(documentPath, fileName);
File.WriteAllBytes(path, response);
My actual implementation don't shows any errors but when I looking for the file on cache folder, nothing are there, just a empty folder. Also try put the file in FileSystem.AppDataDirectory and Environment.GetFolderPath(Environment.SpecialFolder.Personal) but there are no files in any folder
What I'm missing?
Thank's in advance.
string documentPath = FileSystem.CacheDirectory;
string fileName = "downloadfile.pdf";
string path = Path.Combine(documentPath, fileName);
the path will like
"/data/user/0/packagename/cache/downloadfile.pdf"
As you save it to Internal Storage,you couldn't see the files without root permission,if you want to view it,you could use adb tool (application signed by Android Debug)
adb shell
run-as packagename
cd /data/data/packagename
cd cache
ls
then you could see the downloadfile.pdf
or you could save it to External storage,then you could find it in your device File Manager:
//"/storage/emulated/0/Android/data/packagename/files/downloadfile.pdf"
string path = Android.App.Application.Context.GetExternalFilesDir(null).ToString();
When using Google Drive API, I'm having this downloadMetadataFile() here to handle file:
public void downloadMetadataFile(String fileId, String folderStorePath, String fileName) throws IOException, GeneralSecurityException, GoogleException {
String path = folderStorePath + "/" + fileName
java.io.File file = new java.io.File(path);
try (FileOutputStream fileOutputStream = new FileOutputStream(file)) {
Drive drive = createDrive();
drive.files().get(fileId)
.executeMediaAndDownloadTo(fileOutputStream);
}
}
When using above method with folder exists (izakayaTemplate + 居酒屋):
When path=/reports/template/izakayaTemplate/template3.png, the method working file and download template3.png successful from Google Drive
When path=/reports/template/居酒屋/template3.png, the method throw a FileNotFoundException at line try (FileOutputStream fileOutputStream = new FileOutputStream(file))
Can somebody please explain for me about this behavior?
Note:
I'm using SpringBoot 2.5, Java 8, Drive API v3
I'm running this project on Amazon linux 1 as a service by DaemonTool.
In the run config file, I have set
-Dfile.encoding=UTF-8
-Dsun.jnu.encoding=UTF-8 -Dfile.encoding=UTF-8 \
Update 1:
After debug for a while, I found out that the CanonicalPath is wrong for the new file I create but I don't know why it happen.
getPath: /reports/template/居酒屋/template3.png
getAbsolutePath: /reports/template/居酒屋/template3.png
getCanonicalPath: /reports/template/???/template3.png
After searching, I have found the solution for this problem:
Solution: Add export LANG=ja_JP.UTF-8 to the file run
Explanation: canonicalPath is the path file system considers the canonical means to reference the file system object to which it points. So in order for the system to get the canonicalPath to be correct, the environment must have set up correct language environment like in this document: https://docs.oracle.com/cd/E23824_01/html/E26033/glset.html. In my question, the correct language environment is ja_JP.UTF-8
I'm trying to extract attachments from integrity PTC items that are on a linux server from my Windows PC but it keeps giving me errors. The exact same command worked in command line
IntegrationPoint integrationPoint =
IntegrationPointFactory.getInstance().createIntegrationPoint(
hostName,
port,
APIVersion.API_4_16);
System.out.println("Start download Attachment");
// Start the Integrity client.
integrationPoint.setAutoStartIntegrityClient(true);
// Connect to the Integrity server.
Session session = integrationPoint.createSession(username, password);
Command command = new Command(Command.IM, "extractattachments");
command.addOption(new Option("issue", itemID));
command.addOption(new Option("field", "Text Attachments"));
command.addSelection(attachment);
Response response = session.createCmdRunner().execute(command);
I'm getting an error that says
Error encountered trying to get the next name: File paths must be rooted in /export/home/ptc/Integrity/ILMServer11.0/data/tmp: Current file is /export/home/ptc/Integrity/ILMServer11.0/bin/C:\Workspace\document/bear.jpg
Anytime I add cwd to the command it just appends whatever I put after the /bin/ It says it's a InvalidCommandSelectionException and a CommandException
You're missing the outputFile option on the extractattachments command.
This code worked the way I expected it to ...
IntegrationPointFactory ipfact = IntegrationPointFactory.getInstance();
IntegrationPoint ip = ipfact.createIntegrationPoint(hostname, port, APIVersion.API_4_16);
Session session = ip.createNamedSession("test", APIVersion.API_4_16, user, passwd);
CmdRunner cr = session.createCmdRunner();
Command cmd = new Command(Command.IM, "extractattachments");
cmd.addSelection(attachmentName);
cmd.addOption(new Option("issue", issueid));
cmd.addOption(new FileOption("outputFile", "d:/data/" + attachmentName));
cr.execute(cmd);
cr.release();
ip.release();
I am trying to open a file from URL.
Object of URL is created with getResource() method of ClassLoader.
Output URL returned from getResource() method is =
file:/C:/users/
After using URL.getFile() method which returns String as " /C:/users/ " it removes "file:" only not the "/ "
This / gives me a error in opening a file using new FileInputStream.
Error : FileNotFoundException
" / " in the starting of the filename causes the same problem in getting the path object.
Here , value of directory is retrieved from the URL.getResource().getFile()
Path Dest = Paths.get(Directory);
Error received is :
java.nio.file.InvalidPathException: Illegal char <:> at index 2: /C:/Users/
is anyone face such issue ?
Don't use URL.getFile(), it returns the "file" part of the URL, which is not the same as a file or path name of a file on disk. (It looks like it, but there are many ways in which there is a mismatch, as you have discovered.) Instead, call URL.toURI() and pass the resulting URI object to Paths.get()
That should work, as long as your URL points to a real file and not to a resource inside a jar file.
Example:
URL url = getClass().getResource("/some/resource/path");
Path dest = Paths.get(url.toURI());
The problem is that your result path contains leading /.
Try:
ClassLoader loader = Thread.currentThread().getContextClassLoader();
Path path = Paths.get(loader.getResource(filename).toURI());
I have been trying to write a simple ftp client using c# in .NET 2.0 for 3 days now and am
missing something. I I create an ftpWebRequest object and set all its properies.
string uri = host + remoteFile;
System.Net.FtpWebRequest ftp = (FtpWebRequest)(FtpWebRequest.Create(uri));
ftp.Credentials = new System.Net.NetworkCredential(username, password);
ftp.KeepAlive = false;
ftp.UseBinary = true;
ftp.Method = System.Net.WebRequestMethods.Ftp.UploadFile;
But when I go to get the stream, it fails...
System.IO.Stream strm = ftp.GetRequestStream();
Here is the error: "System.Net.WebException: The remote server returned an error: (501) Syntax error in parameters or arguments."
This method SHOULD return the stream I need to write to and many examples do exactly this. I'm not sure what I'm missing. My host looks like this: "ftp://myhostname/" and I've triple checked my credentials.
Please help!
may be ftp.UseBinary = true; is not supported by server?
You are missing the "/" after the host:
string uri = host + "/" + remoteFile;
and the remote file string should look like this: file.txt without any path.
