Error consume route ApiGateway with ocelot and docker service - docker

Question

I am creating an ApiGateway with ocelot that consume an Api service in net core.
The ApiGateway and ApiService are deployed on docker with docker compose of this way:
Docker-compose:
tresfilos.webapigateway:
image: ${DOCKER_REGISTRY-}tresfilosapigateway
build:
context: .
dockerfile: tresfilos.ApiGateway/ApiGw-Base/Dockerfile
tresfilos.users.service:
image: ${DOCKER_REGISTRY-}tresfilosusersservice
build:
context: .
dockerfile: tresfilos.Users.Service/tresfilos.Users.Service/Dockerfile
Docker-compose.override:
tresfilos.webapigateway:
environment:
- ASPNETCORE_ENVIRONMENT=Development
- IdentityUrl=http://identity-api
ports:
- "7000:80"
- "7001:443"
volumes:
- ./tresfilos.ApiGateway/Web.Bff:/app/configuration
tresfilos.users.service:
environment:
- ASPNETCORE_ENVIRONMENT=Development
- ASPNETCORE_URLS=https://+:443;http://+:80
ports:
- "7002:80"
- "7003:443"
volumes:
- ${APPDATA}/Microsoft/UserSecrets:/root/.microsoft/usersecrets:ro
- ${APPDATA}/ASP.NET/Https:/root/.aspnet/https:ro
In configuration ocelot apigateway i define .json like:
"ReRoutes": [
{
"DownstreamPathTemplate": "/api/{version}/{everything}",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "tresfilos.users.service",
"Port": 7002
}
],
"UpstreamPathTemplate": "/api/{version}/user/{everything}",
"UpstreamHttpMethod": [ "POST", "PUT", "GET" ]
},
],
"GlobalConfiguration": {
"BaseUrl": "https://localhost:7001"
}
When i consume the ApiGateway from the url:
http://localhost:7000/api/v1/user/Login/authentication
I have the error in terminal docker:
Why does the above error occur and how to fix it?

Answer 1

What version of Ocelot are you running?
I found another thread which has a similar looking problem and apparently from version 16.0.0 of Ocelot 'ReRoutes' was changed to 'Routes' in the Ocelot configuration file.
The thread I found was - 404 trying to route the Upstream path to downstream path in Ocelot

Answer 2

I fix it of this way:
Change ReRoutes to Routes because ocelot version is 16.0.1
Define config like:
"Routes": [
{
"DownstreamPathTemplate": "/api/{version}/{everything}",
"DownstreamScheme": "http",
"DownstreamHostAndPorts": [
{
"Host": "tresfilos.users.service",
"Port": 7002
}
],
"UpstreamPathTemplate": "/api/{version}/User/{everything}"
},
],
"GlobalConfiguration": {
"BaseUrl": "https://localhost:7001"
}
In postman i send the data in Body like json and not like paramaters.
