(Swift 3,4,5...) Load JSON Array from HTTP Response Body

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

Note: This example requires Chilkat v9.5.0.89 or greater because it uses the GetBodyJarr 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 JsonArray by calling JsonArray.LoadSb.

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

    var resp: CkoHttpResponse? = http.pText("GET", url: "https://www.chilkatsoft.com/exampledata/sampleArray.json", textData: "", charset: "", contentType: "", md5: false, gzip: false)
    if http.lastMethodSuccess == false {
        print("\(http.lastErrorText!)")
        return
    }

    // A JSON array is JSON that begins with "[" and ends with "]"
    let jarr = CkoJsonArray()!

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

    resp!.getBodyJarr(jarr)

    print("\(jarr.emit()!)")

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

    resp = nil
