See more HTTP Examples

Demonstrates how to initialize an HTTP request object from a URL. Swift

func chilkatTest() {
    let req = CkoHttpRequest()!

    // Loads the HTTP request object from a URL
    req.set(fromUrl: "https://www.youtube.com/watch?v=fAZdTchQePc&t=45s")

    // The verb will be "GET"
    print("verb = \(req.httpVerb!)")
    // The path will be "/watch"
    print("path = \(req.path!)")

    // The output of this loop will be
    // 0) v: fAZdTchQePc
    // 1) t: 45s
    var i: Int
    var numParams: Int = req.numParams.intValue
    for i = 0; i <= numParams - 1; i++ {
        print("\(i)) \(req.getParamName(index: i)!): \(req.getParamValue(index: i)!)")
    }

    // View the request that would be sent if HttpSReq is called.
    // The HTTP request will be a GET that looks like this:
    // 
    //     GET /watch?v=fAZdTchQePc&t=45s HTTP/1.1
    //     Host: domain
    // 
    // Note: The HOST header will automatically get filled in with the actual domain when HttpSReq is called.

    print("\(req.generateRequestText()!)")

    // We can add additional params
    req.addParam(name: "artist", value: "Richard Bona")
    req.addParam(name: "musicType", value: "Jazz")
    req.addParam(name: "festival", value: "Estival Jazz Lugano")
    req.addParam(name: "year", value: "2008")

    // Now examine the request that would be sent
    // 
    //     GET /watch?v=fAZdTchQePc&t=45s&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008 HTTP/1.1
    //     Host: domain
    // 
    print("\(req.generateRequestText()!)")

    // We can remove a parameter:
    req.removeParam(name: "t")
    print("\(req.generateRequestText()!)")

    // What happens if we change the request from a GET to a POST?
    req.httpVerb = "POST"
    // The request will now look like this:
    // 
    //    POST /watch HTTP/1.1
    //    Host: domain
    //    Content-Length: 93
    //    
    //    v=fAZdTchQePc&artist=Richard%20Bona&musicType=Jazz&festival=Estival%20Jazz%20Lugano&year=2008
    // 
    print("\(req.generateRequestText()!)")

    // What happens if we make it a multipart/form-data?
    req.contentType = "multipart/form-data"
    // Now the POST looks like this:
    //    
    //    POST /watch HTTP/1.1
    //    Content-Type: multipart/form-data; boundary=------------020906020106050705030807
