I'm completely confused. I do it according to the documentation,
if I make a link with my hands in my browser and insert the AppiKey, then everything works,
if I try to do it through the code, I get this Invalid redirect_uri message.
It must exactly match one of the redirect URIs you've pre-configured for your app (including the path). In console I added redirect url just like in code private const string LoopbackHost = "http://127.0.0.1:4200/"; what is my problem
// Add an ApiKey (from https://www.dropbox.com/developers/apps) here
private const string ApiKey = "XXX";
// This loopback host is for demo purpose. If this port is not
// available on your machine you need to update this URL with an unused port.
private const string LoopbackHost = "http://127.0.0.1:4200/";
// URL to receive OAuth 2 redirect from Dropbox server.
// You also need to register this redirect URL on https://www.dropbox.com/developers/apps.
private readonly Uri RedirectUri = new Uri(LoopbackHost + "authorize");
// URL to receive access token from JS.
private readonly Uri JSRedirectUri = new Uri(LoopbackHost + "token");
public async void MainRun()
{
var accessToken = await this.GetAccessToken();
}
private async Task<string> GetAccessToken()
{
var accessToken = string.Empty;
if (string.IsNullOrEmpty(accessToken))
{
try
{
Console.WriteLine("Waiting for credentials.");
var state = Guid.NewGuid().ToString("N");
var authorizeUri = DropboxOAuth2Helper.GetAuthorizeUri(OAuthResponseType.Token, ApiKey, RedirectUri, state: state);
var http = new HttpListener();
http.Prefixes.Add(LoopbackHost);
http.Start();
Console.WriteLine(1);
//Process.Start("C:\\Program Files\\Internet Explorer\\IExplore.exe", authorizeUri.ToString());
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
string url = authorizeUri.ToString().Replace("&", "^&");

//Console.WriteLine(url);
}
