Downstream ending with / (slash) - Version 23.x.x

[willsbctm]

The / is not being propagated downstream.

Expected Behavior

Using version Ocelot 22.x.x with the following setup:

{
    "Routes": [
        {
            "DownstreamScheme": "http",
            "UpstreamPathTemplate": "/api/v1/endpoint-slash",
            "UpstreamHttpMethod": [
                "Get"
            ],
            "DownstreamPathTemplate": "/v1/endpoint-slash/",
            "AuthenticationOptions": {
                "AuthenticationProviderKey": "Jwt-IDM"
            },
            "DownstreamHostAndPorts": [
                {
                    "Host": "localhost",
                    "Port": 8885
                }
            ]
        }
    ]
}

We got the slash at the end of the downtream applied path:

Actual Behavior

Using version Ocelot 23.x.x with the following setup:

{
    "Routes": [
        {
            "DownstreamScheme": "http",
            "UpstreamPathTemplate": "/api/v1/endpoint-slash",
            "UpstreamHttpMethod": [
                "Get"
            ],
            "DownstreamPathTemplate": "/v1/endpoint-slash/",
            "AuthenticationOptions": {
                "AuthenticationProviderKey": "Jwt-IDM"
            },
            "DownstreamHostAndPorts": [
                {
                    "Host": "localhost",
                    "Port": 8885
                }
            ]
        }
    ]
}

We didn't get the slash at the end of the downtream applied path:

Is that a problem or is that an expected behaviour?

Thanks!

Hello, Will!

That is not a problem at all. It is expected behavior because Ocelot clears up the last slash.
Additionally, Ocelot has many features related to path manipulation and slash workarounds.
Have you read these documents 👉 Routing Empty Placeholders ❔
If you want to keep the last slash, just define a Catch-All route and your slash will be preserved. Also, send URLs to upstream with the slash.

            "UpstreamPathTemplate": "/api/v1/endpoint-slash/{everything}",
            "DownstreamPathTemplate": "/v1/endpoint-slash/{everything}",

or with Catch All route:

            "UpstreamPathTemplate": "/api/{catchAll}",
            "DownstreamPathTemplate": "/{catchAll}",

Hope it helps!
