' See Global Unlock Sample for sample code. ' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http") set http = Server.CreateObject("Chilkat.Http") ' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.HttpRequest") set req = Server.CreateObject("Chilkat.HttpRequest") req.HttpVerb = "POST" req.ContentType = "multipart/form-data" req.Path = "rcvFormDataUpload.aspx" ' Send an "Expect: 100-continue" header in the request. ' This causes the HTTP server to end a 100-continue response ' immediately after receiving the HTTP header. The client ' (Chilkat) will receive this intermediate response, and if ' it's not an error response, it knows that the HTTP server will ' accept the data that is forthcoming. ' The alternative is to get an error response after trying to upload ' the entire contents of the files. req.AddHeader "Expect","100-continue" ' Call AddFileForUpload2 for each file to be uploaded in the HTTP multipart/form-data POST ' To allow Chilkat to determine the content-type automatically based on file-extension, ' call AddFileForUpload instead. ' The 1st arg is the filename passed in the HTTP request. ' The 2nd arg is the path in the local filesytem. ' The file is not loaded into memory. It is streamed directly from the file ' when the HTTP POST is sent. success = req.AddFileForUpload2("starfish.jpg","c:/qa_data/starfish.jpg","image/jpg") If (success <> 1) Then Response.Write "<pre>" & Server.HTMLEncode( req.LastErrorText) & "</pre>" Response.End End If success = req.AddFileForUpload("something.pdf","c:/qa_data/something.pdf") If (success <> 1) Then Response.Write "<pre>" & Server.HTMLEncode( req.LastErrorText) & "</pre>" Response.End End If ' Its also possible to add a file from a string: success = req.AddStringForUpload("test.xml","test.xml","<abc>This is the test.xml content</abc>","utf-8") ' We'll assume success since no files are involved.. ' This sends the HTTP request (with 3 files being uploaded) to ' http://www.mywebserver123abc.com/rcvFormDataUpload.aspx ' resp is a Chilkat.HttpResponse Set resp = http.SynchronousRequest("www.mywebserver123abc.com",80,0,req) If (http.LastMethodSuccess <> 1) Then Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>" Else Response.Write "<pre>" & Server.HTMLEncode( "HTTP response status: " & resp.StatusCode) & "</pre>" ' See the online reference documentation for ' other information that can be obtained from the response object.
