Content-Type setting for downloading using dropbox api v2
Good-day,
im busy trying to write a simple app to download files from dropbox.
im a newbie to mobile dev and asistance would be appricated.
im am receiving this error when downloading.
Dropbox.Api.BadInputException: Error in call to API function "files/download": Bad HTTP "Content-Type" header: "application/x-www-form-urlencoded".
Expecting one of "text/plain", "text/plain; charset=utf-8", "application/octet-stream", "application/octet-stream; charset=utf-8".
var aHttpClient = new HttpClient(); aHttpClient.DefaultRequestHeaders.Add("Content-Type", "application/octet-stream; charset=utf-8"); var aDorpboxConfig = new DropboxClientConfig("ApplicationName") { HttpClient = aHttpClient }; using (var dbx = new DropboxClient("Key_Here", aDorpboxConfig)) { Dropbox.Api.Files.DownloadArg dargs = new Dropbox.Api.Files.DownloadArg(content.Path + "/" + content.Name) ; using (var response = await dbx.Files.DownloadAsync(dargs)) { var file = await response.GetContentAsStringAsync(); } }

There does not appear to be a need for a custom HTTP client in the sample code you have provided. Is the custom HTTP client necessary, or can your code function without one?
The .NET SDK does not require a custom HTTP client in order to function, nor do you need to explicitly set the Content-Type header. Our .NET SDK will automatically create an HTTP client and set the appropriate headers for each API.
- Anoop_BrijmohunHelpful | Level 6Hi Robert, the reason I'm trying to add in the HTTP header is due to the "Bad HTTP content-type" message I am receiving... hence I thought I needed to specify one...
Any ideas or even a sample code extract I could try of one that works
Thanks- DBX_RobertDropbox Staff
I am able to run the following C# sample from our .NET tutorials page. It assumes a file named "file.txt" in the root folder of your Dropbox account.
using System; using System.Threading.Tasks; using Dropbox.Api; namespace sampleApp { class Program { static void Main(string[] args) { var task = Task.Run((Func<Task>)Program.Run); task.Wait(); } static async Task Run() { using (var dbx = new DropboxClient("<OAuth Token>")) { using (var response = await dbx.Files.DownloadAsync("/file.txt")) { Console.WriteLine(await response.GetContentAsStringAsync()); } } } } }
If you are doing this on mobile, are you using a framework like Xamarin?
