How do you include a port number when using Embarcadero C++ TRESTRequest - rest

Question

Here's the compulsory code snippet:
UnicodeString SeizonshaRest::doStuff(UnicodeString strEmail, UnicodeString strPassword)
{
restclient->BaseURL = "http://localhost";
restrequest->Resource = ":60800/home/login";
restrequest->Params->AddItem("email", strEmail);
restrequest->Params->AddItem("password", strPassword);
UnicodeString strId;
restrequest->Execute();
strId = respMain->Content;
return strId;
}
I know this is the wrong way to do it.
What's the correct way to add a port number please?

Answer 1

The port number is attached to the server hostname that the client connects to, not to the resource that the client requests once connected.
Try this:
restclient->BaseURL = "http://localhost:60800";
restrequest->Resource = "home/login";
If you read the documentation, it says:
TCustomRESTClient.BaseURL
Specifies the base URL for all API calls.
All resources and parameters of your requests will be appended to this URL. Please, be aware that a trailing forward slash ("/") is added to the value of the BaseURL property.
TCustomRESTRequest.Resource
This property is added to the base URL to establish a complete URL for the HTTP request.
Important: The Resource value should meet the following limitations:
Does not include the scheme or domain mame.
Does not include the leading slash.
So, your original code would have produced the request URL as http://localhost/:60800/home/login, but the correct URL is http://localhost:60800/home/login instead.

I really wanted to post my code as I can find NO examples of this ANYWHERE
contact.h:
#ifndef contactH
#define contactH
#include <System.Classes.hpp>
#include <IPPeerClient.hpp>
#include <REST.Client.hpp>
//---------------------------------------------------------------------------
class contact;
class contact
{
public:
contact();
~contact() {};
String connect(String query);
TRESTClient *clientContact;
TRESTRequest *reqContact;
TRESTResponse *respContact;
private:
};
contact.cpp:
String contact::connect(String query)
{
clientContact = new TRESTClient(NULL);
reqContact = new TRESTRequest(NULL);
respContact = new TRESTResponse(NULL);
reqContact->Client = clientContact;
reqContact->Response = respContact;
UnicodeString strUrl = "http://myawesomeurl:5150";
reqContact.Resource = query;
clientContact->BaseURL = strUrl;
UnicodeString strInspect;
reqContact->Execute();
strInspect = respContact->Content;
return strInspect;
}
I hope this helps someone as stuck for examples as I was.
