Swift

Example: Http.HttpSb method

Shows how to use the HttpSb method to send an HTTP POST request with a StringBuilder as the request body. The example sends the following request:

POST /echo_request_body.asp HTTP/1.1
Host: chilkatsoft.com
Accept: */*
Accept-Encoding: gzip
Content-Type: application/json
Content-Length: 26

{"greeting":"Hello World"}

Swift

func chilkatTest() {
    var success: Bool = false

    let http = CkoHttp()!
    success = false

    let sb = CkoStringBuilder()!
    sb.append(value: "{\"greeting\":\"Hello World\"}")

    // This URL echoes the contents of the request body, letting us view it.
    var url: String? = "https://chilkatsoft.com/echo_request_body.asp"

    // Send a POST with the contents of the StringBuilder in the HTTP request body.
    let resp = CkoHttpResponse()!
    success = http.httpSb(verb: "POST", url: url, sb: sb, charset: "utf-8", contentType: "application/json", response: resp)
    if success == false {
        print("\(http.lastErrorText!)")
        return
    }

    print("Response Status Code: \(resp.statusCode.intValue)")

    // Examine the request we sent.
    // The LastHeader property stores the HTTP request header of the most recent request sent,
    // and in this instance, the response body mirrors the request body.
    print("\(http.lastHeader!)")
    print("\(resp.bodyStr!)")

    // Output:

    // POST /echo_request_body.asp HTTP/1.1
    // Host: chilkatsoft.com
    // Accept: */*
    // Accept-Encoding: gzip
    // Content-Type: application/json
    // Content-Length: 26
    // 
    // {"greeting":"Hello World"}
