(Swift 2) Load JSON Object from HTTP Response Body

Demonstrates how to load the HTTP response body directly into a JSON object.

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJson method. Prior to v9.5.0.89, and application would need to first copy the HTTP response body to a Chilkat StringBuilder object by calling GetBodySb, and then load the JSON object by calling LoadSb.

func chilkatTest() {
    let http = CkoHttp()
    var success: Bool

    var resp: CkoHttpResponse? = http.PText("GET", url: "https://www.chilkatsoft.com/exampledata/sample.json", textData: "", charset: "", contentType: "", md5: false, gzip: false)
    if http.LastMethodSuccess == false {
        print("\(http.LastErrorText)")
        return
    }

    // A JSON object is JSON that begins with "{" and ends with "}"
    let json = CkoJsonObject()

    // If we wish to transfer (instead of copy) the JSON from the HttpResponse to the JsonObject, then add the keyword "TakeResponseBody" to UncommonOptions
    // This could save memory for extremely large JSON responses.
    resp.UncommonOptions = "TakeResponseBody"

    resp!.GetBodyJson(json)

    json.EmitCompact = false
    print("\(json.Emit())")

    // Note: If UncommonOptions contained "TakeResponseBody", then the response BodyStr will now be empty:
    print("----")
    print("\(resp!.BodyStr)")

    resp = nil
