Question:
How to access Fiware context behind WILMA PEP proxyavoiding CORS restrictions?
Description:
I am accessing a dockerized orin context broker through a React App. All works fine in the local network but when I deploy to a remote server the request gets blocked by CORS.
i create the request using ngsijs library:
componentDidMount() {
var connection = new NGSI.Connection("http://172.16.2.30:1027", {
headers:
{
"X-Auth-Token": token,
"fiware-service": "openiot",
"fiware-servicepath": "/"
}
});
All works with my local address.
I tried to disable cross scripting protection in wilma context broker in the environment configuration of the docker container :
- PEP_PASSWORD=pep_proxy_bc0e6...
- PEP_PROXY_PDP=idm
- PEP_PROXY_MAGIC_KEY=1234
- PEP_PROXY_PUBLIC_PATHS=/version
- PEP_PROXY_CORS_ORIGIN=false
- PEP_PROXY_CORS_METHODS=GET,HEAD,PUT,PATCH,POST,DELETE
- PEP_PROXY_CORS_MAX_AGE=true`
The error which I receive is
Access to fetch at 'http://my_public_domain.net:1027/v2/entities? type=SimpleSensor' from origin 'http://87.254.4.166:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: Redirect is not allowed for a preflight request.
The Keyrock IDM works on the exposed domain without any problem allowing identity management.
We are using Apache to redirect the calls to the docker server.
