The following code shows how to create QUIC requests with the iOS client. For details of the API description, see iOS APIs.

Creating GET Requests

// Session configuration
TQUICURLSessionConfiguration *quicSessionConfiguration = [TQUICURLSessionConfiguration defaultConfiguration];
// Congestion control algorithm
quicSessionConfiguration.congestionType = TQUICCongestionTypeBBR;
// Connection timeout
quicSessionConfiguration.connectTimeoutMillis = 6 * 1000;
// Create SessionManager. See %!s(<nil>) for instructions.
TQUICHTTPSessionManager *quicSessionManager = [[TQUICHTTPSessionManager alloc] initWithSessionConfiguration:quicSessionConfiguration];
       
// (Optional) Serialize via TQUICHTTPRequestSerializer/TQUICHTTPResponseSerializer. See %!s(<nil>) for instructions.

// Initiate a GET request.
[quicSessionManager GET:@"url"
             parameters:nil
                headers:nil
        timeoutInterval:0
       downloadProgress:nil
                success:^(TQUICURLSessionTask * _Nonnull task, id  _Nullable responseObject) {
        // When the request is executed successfully, it returns the response data.
        // Get the response headers. Since this is an HTTP response, it can be converted into NSHTTPURLResponse.
        NSDictionary *headers = [(NSHTTPURLResponse *)task.response allHeaderFields];
        // Get the response body.
        id body = responseObject;
        
        }      failure:^(TQUICURLSessionTask * _Nullable task, NSError * _Nonnull error) {
        // When the request fails to be executed, it returns the error message.
        NSInteger errorCode = error.code;
}];

Creating POST Requests

// Session configuration
TQUICURLSessionConfiguration *quicSessionConfiguration = [TQUICURLSessionConfiguration defaultConfiguration];
// Congestion control algorithm
quicSessionConfiguration.congestionType = TQUICCongestionTypeBBR;
// Connection timeout
quicSessionConfiguration.connectTimeoutMillis = 6 * 1000;
// Create SessionManager. See %!s(<nil>) for instructions.
TQUICHTTPSessionManager *quicSessionManager = [[TQUICHTTPSessionManager alloc] initWithSessionConfiguration:quicSessionConfiguration];
       
// (Optional) Serialize via TQUICHTTPRequestSerializer/TQUICHTTPResponseSerializer. See %!s(<nil>) for instructions.

// Construct body data.
NSData *bodyData;
// Initiate a POST request.
[quicSessionManager POST:@"url"
                    body:bodyData 
                    headers:nil
                    timeoutInterval:timeInterval
                    uploadProgress:^(NSProgress * _Nonnull uploadProgress) {
        
                    } success:^(TQUICURLSessionTask * _Nonnull task, id  _Nullable responseObject) {
                    // When the request is executed successfully, it returns the response data.
                    // Get the response body.
                    id body = responseObject;

                    } failure:^(TQUICURLSessionTask * _Nullable task, NSError * _Nonnull error) {
                    // When the request fails to be executed, it returns the error message.
                    NSInteger errorCode = error.code;
}];

Canceling Requests

// Create SessionManager.

...
// Initiate a request via SessionDataTask. See %!s(<nil>) for instructions.
TQUICURLSessionDataTask *dataTask = 
[quicSessionManager dataTaskWithRequest:request
                         uploadProgress:nil
                       downloadProgress:nil
                       completionHandler:^(NSURLResponse * _Nonnull response, id  _Nullable responseObject, NSError * _Nullable error) {

        // Run callback after the request has finished.

}];

//Send the request.
[dataTask resume];

//Cancel the request.
[dataTask cancel];
