You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.
Error reading file async
I had a problem to download a file ( an Image ) and someone recommended to me to do asynchronously. I changed my code so : Async Function _take_file(ByVal _file As String) As Task .... Dim client As HttpClient = New HttpClient() Dim _Request As HttpRequestMessage = New HttpRequestMessage(HttpMethod.Post, "https://content.dropboxapi.com/2/files/download") _Request.Headers.Add("Authorization", "Bearer " + _token) _Request.Headers.Add("Dropbox-API-Arg", _parametro) Dim _response As HttpResponseMessage = Await client.SendAsync(_Request) Dim _responseStream As Stream = Await _response.Content.ReadAsStreamAsync() Dim myStreamReader As New StreamReader(_responseStream) I have an error on the last line : System.NullReferenceException was unhandled Message: An unhandled exception of type 'System.NullReferenceException' occurred in mscorlib.dllDownload file by Api ( Files/download ) , no error no file
I try to dowload a file by a Api . I have no error and a response with "OK" but i don't see the file. Have i donwloaded it ? where ? can i set up the local directory where save it ? This is my code : ( a big doubt is in content-Type ) Dim _command As String _command = "https://content.dropboxapi.com/2/files/download" Dim Request As HttpWebRequest Request = HttpWebRequest.Create(_command) Request.Method = "POST" Request.KeepAlive = True ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 Or SecurityProtocolType.Tls12 Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls Request.ContentType = "application/octet-stream" Request.UserAgent = "Mozilla/5.0 (Windows NT 6.3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36" ServicePointManager.SecurityProtocol = CType(48, SecurityProtocolType) Or CType(192, SecurityProtocolType) Or CType(768, SecurityProtocolType) Or CType(3072, SecurityProtocolType) Request.AllowAutoRedirect = True Request.Headers.Add("Authorization", "Bearer " & _token) Request.Headers.Add("Dropbox-API-Arg", _parameter) Try Dim Response As HttpWebResponse = Request.GetResponse() Catch ex As WebException Using response = CType(ex.Response, HttpWebResponse) Using reader = New IO.StreamReader(response.GetResponseStream()) _error = reader.ReadToEnd() End Using End Using Catch ex As Exception Throw End Try
I can't download files by command
Download files with wget Hello gentlemen of the community. I have a problem. I've been using "wget" since June 2021 to download a file and since then everything has been fine. But this morning the command does not respond and gives clues as to what may be happening. Below is the command I use and it was working: wget -q --no-check-certificate https://www.dropbox.com/s/4mf0awazg0z0ols/TESTE.7z -O TESTE.7z It simply skips a line without any message. I thank you in advance for your support. Marcos
