Hi, after yesterdays improvement most topic are clear for me.
We habe an AppServer for internal interfaces using TCP, which is working well now. Furthermore the same AppServer is using another WebService (using ROIndyHTTPServer). In the interface is a “Monitor”-function, which gets a HTML-page. Unfortunatly this interface is not usable in my WebBrowser (e.g. Firefox);instead the WSDL is shown instead (I’ve unchecked the “ServeRodl” already).
Any ideas?
Thanks,
Peter

what message you are using? TROSOAPMessage?
how are you trying to call monitor function?

I’ve used in old version ROPostMessage, and I did not change it.
I call the Monitor-function in my Browser.

can you check that another WebService (using ROIndyHTTPServer) has TROPostMessage as dispatcher? if WSDL is shown it indicates that SOAP message is used…

I’ve created the ROIndyHTTPServer again and set the Dispatcher to ROPostMessage. In the project there is no TROSOAPMessage.
If I set ROIndyHTTPServer:ServeRodl, I get the WSDL; if I unset it, I get a “Invalid Path” in the Browser.

I can’t reproduce problem with TROPostMessage in MegaDemo sample.
steps:
- update server-side as:
```auto
TMegaDemoServerMainForm.ROPostMessage.MultiLine := false
```
- test TROPostMessage with this file: [test.htm](https://talk.remobjects.com/uploads/default/original/2X/7/7dadbbccabe563235589bdb72a9b9790c84434c1.txt) (1.6 KB)

I’ve tried the MegaDemo, and it’s the same --\>
when I open the Browser (Firefox) without function, I get the WDSL. If I try a function (e.g. GetServerTime), I get “Invalid Path” like in my project

have you tried to use my .htm?
it sends
```auto
__MessageType=Message&__ InterfaceName=MegaDemoService& __MessageName=GetServerTime&__ ClientID=B51199FE-9E86-4AA1-8CB1-54B4E05AB130&Submit=Submit
```
to [http://localhost:8099/post](http://localhost:8099/post) and recieves response like
```auto
__MessageType=Message&__ InterfaceName=MegaDemoService& __MessageName=GetServerTimeResponse&__ ClientID=B51199FE-9E86-4AA1-8CB1-54B4E05AB130&"Result=2015-07-17

I don’t know, what I should try …
How to use the .htm-file?
In the sample or my project?

you wanted to receive results in browser so launch MegaDemo sample and open attached .htm in Firefox

Ok, it’s working now …
This means, that I must change all interfaces to envlop in all detailled stuff (like \_\_MessageType, \_\_InterfaceName, …)?

you can
- change all interfaces to envlop in all detailled stuff (like \_\_MessageType, \_\_InterfaceName, …)
or
- use [OnCustomResponseEvent](http://wiki.remobjects.com/wiki/TROIndyHTTPServer_Class#OnCustomResponseEvent), something like
```auto
TMegaDemoServerMainForm = class(TForm)
..
procedure ROServerCustomResponseEvent(
const aTransport: IROHTTPTransport; const aRequestStream,
aResponseStream: TStream; const aResponse: IROHTTPResponse;
var aHandled: Boolean);
....
procedure TMegaDemoServerMainForm.FormCreate(Sender: TObject);
...
ROIndyHTTPServer := TROIndyHTTPServer.Create(Self);
ROIndyHTTPServer.OnCustomResponseEvent := ROServerCustomResponseEvent; //added
...
procedure TMegaDemoServerMainForm.ROServerCustomResponseEvent(
const aTransport: IROHTTPTransport; const aRequestStream,
aResponseStream: TStream; const aResponse: IROHTTPResponse;
var aHandled: Boolean);
var
lMessage: IROMessage;
op: TROResponseOptions;
s: ansistring;
begin
if pos('/xxxx',aTransport.PathInfo) = 1 then begin // "xxxx" shouldn't be defined in Server.Dispathers
SetLength(s, aRequestStream.Size);
aResponseStream.Position := 0;
aRequestStream.Read(Pointer(s)^, Length(s));
s := ' __MessageType=Message&__ InterfaceName=MegaDemoService&'+s;
aRequestStream.Size := 0;
aRequestStream.Write(Pointer(s)^, Length(s));
lMessage:= (ROPOSTMessage as IROMessageCloneable).Clone;
MainProcessMessage(lMessage,atransport,aRequestStream,aResponseStream,op);
aHandled := True;
end;
end;
```
in this case, .html can pass only \_\_MessageName:
```auto
```

Evgeny,
I’ve still problems …
How to start MegaDemo (GetServerTime) in the URL?
I’ve tried --\>
[http://localhost:8099/post?\_\_MessageType=Message&\_\_InterfaceName=MegaDemoService&\_\_MessageName=GetServerTime&\_\_ClientId=b51199fe-9e86-4aa1-8cb1-54b4e05ab130](http://localhost:8099/post? __MessageType=Message&__ InterfaceName=MegaDemoService& __MessageName=GetServerTime&__ ClientId=b51199fe-9e86-4aa1-8cb1-54b4e05ab130)
… but I get the WSDL again.
And in our project, we mask (envelop) the messages in ROPostMessageReadFromStream; I think, that sure also work. But I’ll get only “Invalid Path” when I try the Monitor-function. (I’ve tried your solition, but the result is the same …)
Any ideas?
Bye,
Peter

ROSDK supports only POST method instead of GET by default. however you can change this behavior with [OnCustomResponseEvent](http://wiki.remobjects.com/wiki/TROBaseHTTPServer_Class#OnCustomResponseEvent).
update MegaDemoServerMain.pas as
```auto
procedure TMegaDemoServerMainForm.ROServerCustomResponseEvent(
const aTransport: IROHTTPTransport; const aRequestStream,
aResponseStream: TStream; const aResponse: IROHTTPResponse;
var aHandled: Boolean);
var
lMessage: IROMessage;
op: TROResponseOptions;
s: ansistring;
begin
if pos('/xxxx',aTransport.PathInfo) = 1 then begin // "xxxx" shouldn't be defined in Server.Dispathers
s := aTransport.QueryString;
aRequestStream.Size := 0;
aRequestStream.Write(Pointer(s)^, Length(s));
lMessage:= (ROPOSTMessage as IROMessageCloneable).Clone;
MainProcessMessage(lMessage,atransport,aRequestStream,aResponseStream,op);
aHandled := True;
end;
end;
```
note: this update requires another changes from [my earlier post](http://talk.remobjects.com/t/indyhttp-post-get-only-wdsl-in-webbrowser/6553/14).
after this fix, you can use
[http://localhost:8099/xxxx?\_\_MessageType=Message&\_\_InterfaceName=MegaDemoService&\_\_MessageName=GetServerTime&\_\_ClientId=b51199fe-9e86-4aa1-8cb1-54b4e05ab131](http://localhost:8099/xxxx? __MessageType=Message&__ InterfaceName=MegaDemoService& __MessageName=GetServerTime&__ ClientId=b51199fe-9e86-4aa1-8cb1-54b4e05ab131)

Mmmh,
when I update the sample, I’ll get an error in Browser --\>
\_\_MessageType=Exception
\_\_ExceptionClass=EROException
\_\_ExceptionMessage=Unknown message type
"Message&\_\_InterfaceName=MegaDemoService&\_\_MessageName=GetServerTime&\_\_ClientId=b51199fe-9e86-4aa1-8cb1-54b4e05ab131"
\_\_Exception=EROException
Could you please post the final unit (MegaDemoServerMain.pas) ?
Bye,
Peter
