(C# UWP/WinRT) REST Upload Bandwidth Throttle

Demonstrates how to use upload bandwidth throttling with the REST API. This example will upload a file to Drobox using a file stream, with a limit on the bandwidth that can be used for the transfer.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// A Dropbox access token should have been previously obtained.
// Dropbox access tokens do not expire.
// See Dropbox Access Token.

// To use bandwidth throttling, the connection should be made using the socket API.
// This provides numerous properties to customize the connection, such as
// BandwidthThrottleDown, BandwidthThrottleUp, ClientIpAddress, ClintPort, Http Proxy,
// KeepAlive, PreferIpv6, RequireSslCertVerify, SoRcvBuf, SoSndBuf, SoReuseAddr,
// SOCKS proxy, TcpNoSDelay, TlsPinSet, TlsCipherSuite, SslAllowedCiphers, etc.

Chilkat.Socket socket = new Chilkat.Socket();
int maxWaitMs = 5000;
bool success = await socket.ConnectAsync("content.dropboxapi.com",443,true,maxWaitMs);
if (success != true) {
    Debug.WriteLine(socket.LastErrorText);
    Debug.WriteLine("Connect Fail Reason: " + Convert.ToString(socket.ConnectFailReason));
    return;
}

// Set the upload bandwidth throttle rate to 50000 bytes per second.
socket.BandwidthThrottleUp = 50000;

Chilkat.Rest rest = new Chilkat.Rest();

// Tell the REST object to use the connected socket.
rest.UseConnection(socket,true);

// The remainder of this example is identical to the example at:
// Dropbox File Stream Upload.

// Add request headers.
rest.AddHeader("Content-Type","application/octet-stream");
rest.AddHeader("Authorization","Bearer DROPBOX_ACCESS_TOKEN");

// The upload "parameters" contained in JSON passed in an HTTP request header.
// This is the JSON to be added in this example:
// { 
//    "path": "/Homework/lit/hamlet.xml",
//    "mode": "add",
//    "autorename": true,
//    "mute": false
// }

Chilkat.JsonObject json = new Chilkat.JsonObject();
json.AppendString("path","/Homework/lit/hamlet.xml");
json.AppendString("mode","add");
json.AppendBool("autorename",true);
json.AppendBool("mute",false);
rest.AddHeader("Dropbox-API-Arg",json.Emit());

// Almost ready to go...
// Let's setup a file stream to point to a file.
Chilkat.Stream fileStream = new Chilkat.Stream();
fileStream.SourceFile = "qa_data/xml/hamlet.xml";

// Do the upload.  The URL is https://content.dropboxapi.com/2/files/upload.
// We already connected to content.dropboxapi.com using TLS (i.e. HTTPS),
// so now we only need to specify the path "/2/files/upload".

// Note: The file is streamed directly from disk.  (The entire
// file will not be loaded into memory.)
string responseStr = await rest.FullRequestStreamAsync("POST","/2/files/upload",fileStream);
if (rest.LastMethodSuccess != true) {
    Debug.WriteLine(rest.LastErrorText);
    return;
}

// When successful, Dropbox responds with a 200 response code.
if (rest.ResponseStatusCode != 200) {
    // Examine the request/response to see what happened.
    Debug.WriteLine("response status code = " + Convert.ToString(rest.ResponseStatusCode));
    Debug.WriteLine("response status text = " + rest.ResponseStatusText);
    Debug.WriteLine("response header: " + rest.ResponseHeader);
    Debug.WriteLine("response body (if any): " + responseStr);
    Debug.WriteLine("---");
    Debug.WriteLine("LastRequestStartLine: " + rest.LastRequestStartLine);
    Debug.WriteLine("LastRequestHeader: " + rest.LastRequestHeader);
    return;
}

// The response is JSON.
Chilkat.JsonObject jsonResp = new Chilkat.JsonObject();
jsonResp.EmitCompact = false;
jsonResp.Load(responseStr);

// Show the JSON response.
Debug.WriteLine(jsonResp.Emit());

// Returns JSON that looks like this:
// { 
//   "name": "hamlet.xml",
//   "path_lower": "/homework/lit/hamlet.xml",
//   "path_display": "/Homework/lit/hamlet.xml",
//   "id": "id:74FkdeNuyKAAAAAAAAAAAQ",
//   "client_modified": "2016-06-02T23:19:00Z",
//   "server_modified": "2016-06-02T23:19:00Z",
//   "rev": "9482db15f",
//   "size": 279658
// }

// Sample code to get data from the JSON response:
int size = jsonResp.IntOf("size");
Debug.WriteLine("size = " + Convert.ToString(size));

string rev = jsonResp.StringOf("rev");
Debug.WriteLine("rev = " + rev);

string clientModified = jsonResp.StringOf("client_modified");
Chilkat.CkDateTime ckdt = new Chilkat.CkDateTime();
ckdt.SetFromTimestamp(clientModified);
bool bLocalTime = true;
Chilkat.DtObj dt = ckdt.GetDtObj(bLocalTime);
Debug.WriteLine(Convert.ToString(dt.Day) + "/" + Convert.ToString(dt.Month) + "/" + Convert.ToString(dt.Year) + " " + Convert.ToString(dt.Hour)
     + ":" + Convert.ToString(dt.Minute));
