See more HTTP Examples

Creates a URL with URL encoded query params, and sends an HTTPS GET to the URL. Java

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

    // Create a URL with URL-encoded query params.
    CkStringBuilder sbUrl = new CkStringBuilder();
    sbUrl.Append("https://www.example.com/something?");

    // If we know a query param value does not have any special chars requiring URL encoding,
    // just add it.  In this case, there is no need to URL encode "123" because "123" url encoded is still just "123".
    sbUrl.Append("abc=123&xyz=");

    CkStringBuilder sbValue = new CkStringBuilder();
    sbValue.Append("this is a test");

    sbUrl.Append("msg=");
    sbUrl.Append(sbValue.getEncoded("url","utf-8"));

    // sbUrl contains:  https://www.example.com/something?abc=123&xyz=msg=this%20is%20a%20test
    System.out.println(sbUrl.getAsString());

    // Send the GET request and get the response body, which is assumed to be text of some sort (HTML, XML, JSON, etc.)
    // (Chilkat automatically decompresses gzipped responses)
