(Swift) HTTP HEAD RequestSends an HTTP HEAD request and gets the response. Note: The response to an HTTP HEAD request is always just the response header. The reponse body is always 0 length (thus the reason it's called a "HEAD" request..)
func chilkatTest() { // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. let http = CkoHttp()! // If the URL uses "https://", then the connection will be TLS. // Otherwise it will be TCP. var resp: CkoHttpResponse? = http.getHead("https://example-code.com/") if http.lastMethodSuccess != true { // A failure is when we don't get any response. It could be a timeout, an inability to connect, etc. // For example, a "404 Not Found" response is still a response, and thus deemed success in terms of the API.. print("\(http.lastErrorText!)") return } // Examine the response. print("Status Code = \(resp!.statusCode.intValue)") print("Status Line = \(resp!.statusLine!)") print("Status Text = \(resp!.statusText!)") print("Full Response Header:") print("\(resp!.header!)") print("----") var numHeaderFields: Int = resp!.numHeaderFields.intValue print("Num Header Fields: \(numHeaderFields)") var i: Int for i = 0; i <= numHeaderFields - 1; i++ { print("\(resp!.getHeaderName(i)!): \(resp!.getHeaderValue(i)!)") } resp = nil } |
