CORS/AJAX with fpHTTPap Lazarus
«
on:
November 22, 2021, 04:27:45 pm »
Could you help me with an example of an API using:
fphttpapp, httpdefs, httproute, fpjson
that implements CORS to receive AJAX requests ??
thanks

fpjson not required. CORS is implemented as a HTTP OPTIONS handler, so practically just:
Code: Pascal
[Select]
[+]
[-]
procedure
Whatever
(
ARequest
:
TRequest
;
AResponse
:
TResponse
)
;
var
Origin
:
String
;
begin
if
ARequest
.
Method
=
'OPTIONS'
then
begin
// handle CORS request
// normally, you would check the sent ORIGIN header, to see who sent the request
Origin
:
=
HttpRequest
.
GetCustomHeader
(
'Origin'
)
;
// for instance, you only allow it from your own domain
if
Origin
=
'myowndomain.com'
then
begin
// send the header that allows it to request
AResponse
.
SetCustomHeader
(
'Access-Control-Allow-Origin'
,
Origin
)
;
// or if you allow it from anywhere, use '*' instead of Origin
end
;
end
;
end
;
begin
HTTPRouter
.
RegisterRoute
(
'/'
,
@
Whatever
)
;
end
.
