Intraweb for Rest API POST - ShaneStump - 11-25-2019
Howdy All!
I am exposing my web reservation system to Viator and I need to implement a REST api around my internal classes.
I have written content handlers for each REST api call with the appropriate path.
I am using Advanced REST Client to test my application running as a service.
I put my URL and method to POST. I copy my XML for processing into the Body of the request and issue it.
From within the C++ Builder IDE, I set and get a breakpoint on handler's Execute().
I can't see anywhere in the THttpRequest object where the content passed in is.
How do I read / fetch it from within my event?
Thanks in advance,
Shane

Content Handlers.... are you using them already?
function xxx.Execute(aRequest: THttpRequest; aReply: THttpReply;
const aPathname: string; aSession: TIWApplication; aParams: TStrings): Boolean;
if aRequest.CommandType = hcPost then begin
with TStreamReader.Create(aRequest.PostStream) do try
xJSON := ReadToEnd;
finally Free; end;

Thanks for answering.
I have using a TContentBase based handler and when my REST api handler's Execute() is called, I am trying to figure out how to extract the content from the body of the request.
The aRequest parameter does NOT have a PostStream parameter. I can't see how to retrieve the XML data I sent in the body of the initial request.
What am I missing?
Thanks,
Shane

Hi Shane, look this demo: https://github.com/Atozed/IntraWeb/blob/master/XIV/Delphi/PostDataDemo/IW.Content.XML.pas
RE: Intraweb for Rest API POST - ShaneStump - 11-25-2019
Howdy Jose!
I am NOT attaching an XML file. I am putting it into the body of the request.
The Request->Files->Count is zero any how (I had already checked that).
I have tried several things with Advanced Rest Client and when I look at the RawHeaders property of THttpRequest, the last one lists as "content-length: 2500".
I can't figure out how to get the content. The content is an XML stream like below:
<?xml version="1.0" encoding="UTF-8"?>

The stream is 2500 bytes.
How do I get it?
Thanks in advance,

RE: Intraweb for Rest API POST - ShaneStump - 11-26-2019
Good morning,
I sure hope I get an answer before long as I have a conference call with my board in 4 hours and I have to give a timeframe on this.
I just need to know if I can do this in IW or if I need to look for a different solution.
Thanks,
Shane

Hi Shane, this picture [https://github.com/Atozed/IntraWeb/blob/master/XIV/Delphi/PostDataDemo/How%20to%20simulate%20a%20request%20using%20Firefox%20Poster%20addon.png] show how you can test the demo. The demo is not attached, is sent in body, IW get the body.
RE: Intraweb for Rest API POST - ShaneStump - 11-26-2019
Thanks.
I will have a further look after my board gives me a colonoscopy this morning?.
All the best,
Shane
RE: Intraweb for Rest API POST - ShaneStump - 11-26-2019
Jose,
It is working in Delphi example but not in my C++ application. The handler gets executed, but the content isn't there.
I will need to see if there is anything else changed or if the is a compatibility with C++ Builder.
Thanks,
Shane
Howdy All!
I figured out the DIFFERENCE in the example / my code!
In the ServerController, need to add the following line to my ConfigBase event:
RegisterContentType(L"application/xml");
Now it works!
Thanks for the help,
Shane

Sorry that section of code I pulled was from Indy directly although inside of IntraWeb code.
For IntraWeb it does add it to the file list as you were already looking at. I will ask Alexandre to take a look and respond though as I know in some cases you have to take additional steps for certain types of contents.
