Sending Parameters with a HTTP POST Request


Sending Parameters with a HTTP POST Request

By default, when a page is converted to PDF, SelectPdf performs a GET request for that page to obtain its content. SelectPdf Library for .NET can be used to send additional parameters to the web page that is converted using a HTTP POST request.

This can be done using the HttpPostParameters property of the HtmlToPdfOptions object.

Sample Code

This sample shows how to send parameters using a HTTP POST request to the page that will be converted using the html to pdf converter from SelectPdf Pdf Library for .NET.

Copy

// instantiate a html to pdf converter object
HtmlToPdf converter = new HtmlToPdf();

// set the HTTP POST parameters
converter.Options.HttpPostParameters.Add(name1, value1);
converter.Options.HttpPostParameters.Add(name2, value2);
converter.Options.HttpPostParameters.Add(name3, value3);
converter.Options.HttpPostParameters.Add(name4, value4);

// create a new pdf document converting an url
PdfDocument doc = converter.ConvertUrl(url);

// save pdf document
doc.Save("Sample.pdf");

// close pdf document
doc.Close();

' instantiate a html to pdf converter object
Dim converter As New HtmlToPdf()

' set the HTTP POST parameters
converter.Options.HttpPostParameters.Add(name1, value1)
converter.Options.HttpPostParameters.Add(name2, value2)
converter.Options.HttpPostParameters.Add(name3, value3)
converter.Options.HttpPostParameters.Add(name4, value4)
