(Mono C#) Get Response Header for Method that does not Return HttpResponse ObjectDemonstrates how to get the response header and individual response header fields for a method that does not return an HTTP response object. (If a method returns an HHTTP response object, then the response header information should be obtained from the response object.)
// This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. Chilkat.Http http = new Chilkat.Http(); string strHtml = http.QuickGetStr("https://www.duckduckgo.com/"); if (http.LastMethodSuccess == false) { Debug.WriteLine(http.LastErrorText); return; } Debug.WriteLine(http.LastResponseHeader); // Here's a sample HTTP response header: // Server: nginx // Date: Wed, 30 Sep 2020 13:13:02 GMT // Content-Type: text/html; charset=UTF-8 // Transfer-Encoding: chunked // Connection: keep-alive // Vary: Accept-Encoding // ETag: W/"5f7371f4-1683" // Strict-Transport-Security: max-age=31536000 // X-Frame-Options: SAMEORIGIN // Content-Security-Policy: default-src https: blob: data: 'unsafe-inline' 'unsafe-eval'; frame-ancestors 'self' // X-XSS-Protection: 1;mode=block // X-Content-Type-Options: nosniff // Referrer-Policy: origin // Expect-CT: max-age=0 // Expires: Wed, 30 Sep 2020 13:13:01 GMT // Cache-Control: no-cache // Content-Encoding: gzip // We can load it into a Chilkat MIME object to get header field values: Chilkat.Mime mime = new Chilkat.Mime(); bool success = mime.LoadMime(http.LastResponseHeader); if (success == false) { Debug.WriteLine(mime.LastErrorText); return; } // Get MIME header field values using Chilkat MIME... Debug.WriteLine("----"); Debug.WriteLine("ETag: " + mime.GetHeaderField("ETag")); |
