Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

// Note: Requires Chilkat v9.5.0.64 or greater.

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

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

// Before sending REST API calls, the REST object needs to be
// initialized for OAuth1.
// See Xero 2-Legged OAuth1 Setup for sample code.

// Assuming the REST object's OAuth1 authenticator is setup, and the initial
// connection was made, we may now send REST HTTP requests..

// --------------------------------------------------------------
// This example will upload an image attachment to a receipt.

string endPoint = "Receipts";
string receiptID = "c4f40e59-c390-0001-caff-ce731c707d00";
// This JPG image can be downloaded from https://www.chilkatsoft.com/syncedImages/penguins.jpg
string filename = "penguins.jpg";

rest.AddHeader("Content-Type","image/jpeg");

// Load the JPG image from a file.
Chilkat.BinData jpgData = new Chilkat.BinData();

// We could alternatively get it from a URL like this:
Chilkat.BinData jpgDataFromWeb = new Chilkat.BinData();
Chilkat.Http http = new Chilkat.Http();
success = await http.QuickGetBdAsync("https://www.chilkatsoft.com/syncedImages/penguins.jpg",jpgDataFromWeb);

// Upload with a POST

if (success != true) {

}

// A 200 response is expected for actual success.
if (rest.ResponseStatusCode != 200) {
    Debug.WriteLine(sbResponseBody.GetAsString());
    return;
}

// Examine the XML response
Debug.WriteLine(sbResponseBody.GetAsString());

// A successful response looks like this:
