Introduction: In this blog, we will see how to get response from Rest Api through GET call Solution:  Consisting of basic authentication, we will pass username and password in byteStr and for the endpoint we will put it in url in below code. class CFSJSTestRestAPI { public static void main(Args _args) { int find; str url,aosUri,activeDirectoryTenant; str activeDirectoryClientAppId; str activeDirectoryClientAppSecret; str postData,activeDirectoryResource; str aadClientAppSecret,oAuthHeader; str returnValue,jsonString,jsondszstr; System.Net.HttpWebRequest request; System.Net.HttpWebResponse response; System.Byte[] byteArray; System.IO.Stream dataStream; System.IO.StreamReader streamRead; System.IO.StreamWriter streamWrite; System.Net.ServicePoint servicePoint; System.Net.ServicePointManager servicePointmgr; System.Net.HttpVersion version; CLRObject clrObj; Newtonsoft.Json.JsonReader reader; System.Text.Encoding utf8; Counter countCounter; Object obj; Map data; System.Byte[] byteArraynew; System.Net.WebHeaderCollection headers = new System.Net.WebHeaderCollection(); new InteropPermission(InteropKind::ClrInterop).assert(); str byteStr = strfmt(‘%1:%2’, “USERNAME”, “PASSWORD”); headers = new System.Net.WebHeaderCollection(); url = “http://dummy.restapiexample.com/api/v1/employees”; clrObj = System.Net.WebRequest::Create(url); request = clrObj; request.set_Method(“GET”); request.set_KeepAlive(true); request.set_ContentType(“application/json”); utf8 = System.Text.Encoding::get_UTF8(); byteArraynew = utf8.GetBytes(byteStr); byteStr = System.Convert::ToBase64String(byteArraynew); headers.Add(“Authorization”, ‘Basic ‘ + byteStr); request.set_Headers(headers); servicePoint = request.get_ServicePoint(); System.Net.ServicePointManager::set_Expect100Continue(false); System.Net.ServicePointManager::set_SecurityProtocol(System.Net.SecurityProtocolType::Tls12); response = request.GetResponse(); dataStream = response.GetResponseStream(); streamRead = new System.IO.StreamReader(dataStream); jsonString = streamRead.ReadToEnd(); info(strFmt(“RESPONSE: %1”,jsonString)); dataStream.Close(); response.Close(); } } Thanks for reading !!!
