HTTP Methods - GET and DELETE

Demonstrate a method for sending HTTP requests that don't have a request body, such as for GET or DELETE requests. Swift

func chilkatTest() {
    var success: Bool = false

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    let http = CkoHttp()!

    // Specifiy a session log file so we can see the exact request/response
    http.sessionLogFilename = "c:/aaworkarea/sessionLog.txt"

    // Perhaps add a custom header or two..
    http.setRequestHeader(name: "x-exz-date", value: "20201012T235046Z")
    http.setRequestHeader(name: "x-exz-id", value: "1234")

    // Send a GET request to https://www.example.com/someting?param1=123&param2=abc
    var url: String? = "https://www.example.com/someting?param1=123&param2=abc"
    let resp = CkoHttpResponse()!
    success = http.httpNoBody(verb: "GET", url: url, response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // The GET request that is sent looks like this.
    // The Accept and Accept-Encoding headers are automatically added by default.

    // 	GET /someting?param1=123&param2=abc HTTP/1.1
    // 	Host: www.example.com
    // 	Accept: */*
    // 	Accept-Encoding: gzip
    // 	x-exz-date: 20201012T235046Z
    // 	x-exz-id: 1234

    // Get the response status
    var statusCode: Int = resp.statusCode.intValue
    print("Response status: \(statusCode)")

    // Get the response body
    print("\(resp.bodyStr!)")

    // -------------------------------------------------------------
    // Let's say we want to send a DELETE request, and we only want to accept an application/json response,
    // and we don't want gzipped responses...

    // First remove the previously specified custom headers.
    http.clearHeaders()

    // Indicate we only accept application/json non-gzipped responses.
    http.accept = "application/json"
    http.allowGzip = false

    // Send a DELETE request to https://www.example.com/deleteSomething
    url = "https://www.example.com/deleteSomething"
    success = http.httpNoBody(verb: "DELETE", url: url, response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    // The DELETE request that is sent looks like this.
    // The empty Accept-Encoding header value means we only want non-compressed responses.

    // 	DELETE /deleteSomething HTTP/1.1
    // 	Host: www.example.com
    // 	Accept: application/json
    // 	Accept-Encoding: 

    // Get the response status
    statusCode = resp.statusCode.intValue
    print("Response status: \(statusCode)")

    // Get the response body
    print("\(resp.bodyStr!)")
