HTTP Response Inspection

See more HTTP Examples

Demonstrates how to inspect the HTTP response, including the status code, status text, and response headers, for Chilkat methods that don't use an HttpResponse object. Swift

func chilkatTest() {
    let http = CkoHttp()!

    // Returns the contents of the response body.
    var jsonText: String? = http.quickGetStr(url: "https://chilkatsoft.com/helloWorld.json")

    // Examine the response status code.
    print("response status code: \(http.lastStatus.intValue)")

    // Examine the response status text
    print("response status text: \(http.lastStatusText!)")

    // Examine the full response header.
    print("response header:")
    print("\(http.lastResponseHeader!)")
    print("----")

    // Examine the response content-type
    print("LastContentType = \(http.lastContentType!)")

    // Examine the response last-mod date
    print("LastModDate = \(http.lastModDate!)")

    // Load the response header into a Chilkat MIME object to access its fields individually.
    let mime = CkoMime()!
    mime.load(mimeText: http.lastResponseHeader)

    var numHeaders: Int = mime.numHeaderFields.intValue
    var i: Int = 0
    print("---- MIME Headers ----")
    while i < numHeaders {
        print("name:  \(mime.getHeaderFieldName(index: i)!)")
        print("value: \(mime.getHeaderFieldValue(index: i)!)")
        i = i + 1
    }

    print("----")

    // Get a header field value by name:
    print("ETag: \(mime.getHeaderField(name: "ETag")!)")

    // Output:

    // response status code: 200
    // response status text: OK
    // response header:
