(Visual FoxPro) Add, Remove, Update MIME Header FieldsDemonstrates how to add, remove, or update the content of MIME header fields. Note: This example requires Chilkat v11.0.0 or greater.
LOCAL lnSuccess LOCAL loMime LOCAL lnBAllOccurrences LOCAL loMpRelated LOCAL loPJpg lnSuccess = 0 * This example requires the Chilkat API to have been previously unlocked. * See Global Unlock Sample for sample code. loMime = CreateObject('Chilkat.Mime') * The contents of this MIME file are shown below, * and is also available at https://www.chilkatsoft.com/sampleMime.txt lnSuccess = loMime.LoadMimeFile("qa_data/mime/sampleMime.txt") IF (lnSuccess = 0) THEN ? loMime.LastErrorText RELEASE loMime CANCEL ENDIF * The MIME used in this example has the following nested structure * * multipart/alternative * text/plain * multipart/related * text/html * image/jpeg * * Adding a top-level MIME header is easy. loMime.AddHeaderField("hello-world","Hello World!") * If a header field of the same name already exists, the AddHeaderField * method adds a duplicate. loMime.AddHeaderField("Subject","This is the 2nd Subject header.") ? loMime.GetEntireHead() ? "-" * The top-level header now looks like this: * * Subject: Test email. * Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0" * MIME-Version: 1.0 * hello-world: Hello World! * Subject: This is the 2nd Subject header. * * The RemoveHeaderField method can remove the 1st occurrance, or all occurrences. lnBAllOccurrences = 1 * Remove all occurrences of the Subject header; loMime.RemoveHeaderField("Subject",lnBAllOccurrences) ? loMime.GetEntireHead() ? "-" * After removing all Subject header fields, the top-level header now looks like this: * * Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0" * MIME-Version: 1.0 * hello-world: Hello World! * * The content of a header field can be updated by calling SetHeaderField. * If the header field does not already exist, it is added. Otherwise it is updated. * Note: The order of header fields SHOULD never matter. loMime.SetHeaderField("hello-world","Goodbye World.") ? loMime.GetEntireHead() ? "-" * Now we have: * * Content-Type: multipart/alternative; boundary="------------DB171738719FB06D67DEBAA0" * MIME-Version: 1.0 * hello-world: Goodbye World. * * To add/update/delete header fields in sub-parts, navigate to * the sub-part and do the same.. loMpRelated = CreateObject('Chilkat.Mime') loMime.PartAt(1,loMpRelated) loPJpg = CreateObject('Chilkat.Mime') loMpRelated.PartAt(1,loPJpg) * Add a header to the image/jpeg sub-header. loPJpg.SetHeaderField("CustomHeader","This is the custom header value.") * View the entire MIME.. ? loMime.GetMime() * -------------------------------------------------------------- * -------------------------------------------------------------- * The MIME sample file loaded at the beginning of this example * contains the following MIME: * Subject: Test email. * Content-Type: multipart/alternative; * boundary="------------DB171738719FB06D67DEBAA0" * MIME-Version: 1.0 * * --------------DB171738719FB06D67DEBAA0 * Content-Type: text/plain; charset="utf-8"; format=flowed * Content-Transfer-Encoding: 7bit * * This is a test. * * --------------DB171738719FB06D67DEBAA0 * Content-Type: multipart/related; * boundary="------------A940F1230E6F0105F03DB2CB" * * --------------A940F1230E6F0105F03DB2CB * Content-Type: text/html; charset="utf-8" * Content-Transfer-Encoding: 8bit * * <html><head> * <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> * </head> * <body bgcolor="#FFFFFF" text="#000000"> * <p>This is a test. <img src="cid:part1.E16AE3B4.1505C436@chilkatsoft.com" height="20" width="20"></p> * </body> * </html> * * --------------A940F1230E6F0105F03DB2CB * Content-Type: image/jpeg; name="starfish20.jpg" * Content-Transfer-Encoding: base64 * Content-ID: <part1.E16AE3B4.1505C436@chilkatsoft.com> * Content-Disposition: inline; filename="starfish20.jpg" * * /9j/4AAQSkZJRgABAQEASABIAAD//gAmRmlsZSB3cml0dGVuIGJ5IEFkb2JlIFBob3Rvc2hvcD8g * NC4w/9sAQwAQCwwODAoQDg0OEhEQExgoGhgWFhgxIyUdKDozPTw5Mzg3QEhcTkBEV0U3OFBtUVdf * YmdoZz5NcXlwZHhcZWdj/9sAQwEREhIYFRgvGhovY0I4QmNjY2NjY2NjY2NjY2NjY2NjY2NjY2Nj * Y2NjY2NjY2NjY2NjY2NjY2NjY2NjY2NjY2Nj/8IAEQgAFAAUAwERAAIRAQMRAf/EABcAAAMBAAAA * AAAAAAAAAAAAAAIDBAX/xAAYAQADAQEAAAAAAAAAAAAAAAABAgMEAP/aAAwDAQACEAMQAAAB2kZY * NNEijWKddfTmLgALWH//xAAbEAACAgMBAAAAAAAAAAAAAAABAgMRAAQSE//aAAgBAQABBQL0XqN+ * pM2aqJGMiqFFCyg7z//EABwRAAICAgMAAAAAAAAAAAAAAAERAAIQIQMSUf/aAAgBAwEBPwHqU5aq * Axx+y1tMQl4elj//xAAcEQEAAQUBAQAAAAAAAAAAAAABEQACEBIhA1H/2gAIAQIBAT8B3Bhqy7Zc * enyiwmGgDhiOzj//xAAdEAABAwUBAAAAAAAAAAAAAAABAAIREBIhIkFR/9oACAEBAAY/ArZyn+Cg * xtxWuJaoCnqDuin/xAAcEAABBAMBAAAAAAAAAAAAAAABABEhYRAxQVH/2gAIAQEAAT8hkEwPUUR9 * DYfE4nxtRpIkBTsayuALIiuY/9oADAMBAAIAAwAAABDWPTsf/8QAGhEAAwADAQAAAAAAAAAAAAAA * AAEREDFBIf/aAAgBAwEBPxC0DVPcWm+Ce4OesrkE6bjH/8QAGBEBAQEBAQAAAAAAAAAAAAAAAREA * QRD/2gAIAQIBAT8QahMiOc8YgSrnTY3ELclHXn//xAAcEAEBAAIDAQEAAAAAAAAAAAABEQAhMUFx * EFH/2gAIAQEAAT8Qn3igmSZSj+c4N4zapMy9IjFV98wncN2iuLFsCEbDGxQkI6RO/n//2Q== * * --------------A940F1230E6F0105F03DB2CB-- * * --------------DB171738719FB06D67DEBAA0-- * RELEASE loMime RELEASE loMpRelated RELEASE loPJpg |
