如果条件不满足，则“短路”YARP RequestTransform 并返回自定义响应

Question

I am having issues figuring out how to stop a YARP request early and return a custom response if a certain condition is not met inside a request transform.

builderContext.AddRequestTransform(async transformContext =>
{
        [...]

        if (!condition)
        {
                // TODO: stop request and return response
        }

        [...]
});

I have tried simply setting transformContext.HttpContext.Response.Status to a non-success status code as you would do for middleware, however this does not seem to work, and I have not been able to find another solution to this issue.

Answer 1

Perhaps you should use a middleware. If you take a look at the documentation, you can intercept using a middleware.

if you return before next() , the proxy does not get called.
