GetCDNUrl

tip

This method was added to support clients (like very old versions of Unity - i.e. circa 2016) that cannot handle HTTP Redirects. This method allows clients to pre-resolve the CDN endpoint for the file to download.

This call is not required in the great majority of cases. Just use the regular file download URL and the platform will automatically re-direct the client to the appropriate CDN URL.

Returns the CDN url for a file object.

C#

string cloudPath = "dir1/dir2";
string cloudFilename = "filename";
SuccessCallback successCallback = (response, cbObject) =>
{
    Debug.Log(string.Format("Success | {0}", response));
};
FailureCallback failureCallback = (status, code, error, cbObject) =>
{
    Debug.Log(string.Format("Failed | {0}  {1}  {2}", status, code, error));
};

_bc.FileService.GetCDNUrl(cloudPath, cloudFilename, successCallback, failureCallback);

C++

const char *cloudPath = "dir1/dir2";
const char *cloudFilename = "filename";
_bc->getFileService()->getCDNUrl(cloudPath, cloudFilename, this);

Objective-C

NSString *cloudPath = @"dir1/dir2";
NSString *cloudFilename = @"filename";
BCCompletionBlock successBlock;      // define callback
BCErrorCompletionBlock failureBlock; // define callback

[[_bc fileService] getCDNUrl:cloudPath
              cloudFilename:cloudFilename
            completionBlock:successBlock
       errorCompletionBlock:failureBlock
                   cbObject:nil];

Java

String cloudPath = "dir1/dir2";
String cloudFilename = "filename";
this; // implements IServerCallback

_bc.getFileService().getCDNUrl(cloudPath, cloudFilename, this);

public void serverCallback(ServiceName serviceName, ServiceOperation serviceOperation, JSONObject jsonData)
{
    System.out.print(String.format("Success | %s", jsonData.toString()));
}
public void serverError(ServiceName serviceName, ServiceOperation serviceOperation, int statusCode, int reasonCode, String jsonError)
{
    System.out.print(String.format("Failed | %d %d %s", statusCode,  reasonCode, jsonError.toString()));
}

JavaScript

var cloudPath = "dir1/dir2";
var cloudFilename = "filename";

_bc.file.getCDNUrl(cloudPath, cloudFilename, result =>
{
    var status = result.status;
    console.log(status + " : " + JSON.stringify(result, null, 2));
});

Dart

var  cloudPath = "dir1/dir2";
var  cloudFilename = "filename";

ServerResponse result = await _bc.fileService.getCDNUrl(cloudPath:cloudPath, cloudFilename:cloudFilename);

if (result.statusCode == 200) {
    print("Success");
} else {
    print("Failed ${result.error['status_message'] ?? result.error}");
}

Cloud Code

var cloudPath = "dir1/dir2";
var cloudFilename = "filename";
var fileProxy = bridge.getFileServiceProxy();

var postResult = fileProxy.getCDNUrl(cloudPath, cloudFilename);
if (postResult.status == 200) {
    // Success!
}
