By default, TosClient includes a signature in the request header when initiating a request to the server. The SDK also supports constructing signed URLs. These URLs can be used directly to initiate HTTP requests or shared with third parties to enable access authorization.

Sample Code

The following code demonstrates how to generate a signed URL.

TOSCredential *credential = [[TOSCredential alloc] initWithAccessKey:@"accesskey" secretKey:@"secretkey"];​
TOSEndpoint *tosEndpoint = [[TOSEndpoint alloc] initWithURLString:@"endpoint" withRegion:@"region"];​
TOSClientConfiguration *config = [[TOSClientConfiguration alloc] initWithEndpoint:tosEndpoint credential:credential];​
TOSClient *client = [[TOSClient alloc] initWithConfiguration:config];​
​
TOSPreSignedURLInput *input = [TOSPreSignedURLInput new];​
input.tosBucket = @"bucket-name";​
input.tosKey = @"object-name";​
input.tosHttpMethod = TOSHTTPMethodTypeGet;​
TOSTask *task = [client preSignedURL:input];​
[task continueWithBlock:^id _Nullable(TOSTask * _Nonnull task) {​
    if (!task.error) {​
        NSLog(@"Presigned success.");​
        TOSPreSignedURLOutput *output = task.result;​
        NSString *url = output.tosSignedUrl;​
    } else {​
        NSLog(@"Presigned failed, error: %@.", task.error);​
    }​
    return nil;​
}];​
