If you don't have Acumatica 2017R2, then you have to create your own extension project and then you can call it from your Acumatica code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Net;
namespace MyApp
{
public static class Utility
{
private static WebRequest CreateRequest(string url, Dictionary headers)
{
if (Uri.IsWellFormedUriString(url, UriKind.Absolute))
{
WebRequest req = WebRequest.Create(url);
if (headers != null)
{
foreach (var header in headers)
{
if (!WebHeaderCollection.IsRestricted(header.Key))
{
req.Headers.Add(header.Key, header.Value);
}
}
}
return req;
}
else
{
throw(new ArgumentException("Invalid URL provided.", "url"));
}
}
public static string MakeRequest(string url, Dictionary headers = null)
{
WebResponse resp = CreateRequest(url, headers).GetResponse();
StreamReader reader = new StreamReader(resp.GetResponseStream());
string response = reader.ReadToEnd();
reader.Close();
resp.Close();
return response;
}
public static byte[] MakeRequestInBytes(string url, Dictionary headers = null)
{
byte[] rb = null;
WebResponse resp = CreateRequest(url, headers).GetResponse();
using (BinaryReader br = new BinaryReader(resp.GetResponseStream()))
{
rb = br.ReadBytes((int)resp.ContentLength);
br.Close();
}
resp.Close();
return rb;
}
}
}
You can then call it like this:
try
{
Utility.MakeRequest(theUrl, anyHeadersYouNeed);
}
catch(System.Net.WebException ex)
{
throw(new PXException("There was an error.", ex));
}
