Asp.Net核心HTTPContext和RewritePath

Question

I am converting over an old HttpModule into a new MiddleWare and want to know what is the correct way for Rewriting the Path in the MiddleWare .

The old module uses this:

context.RewritePath(path, string.Empty, queryPart);

Answer 1

For simple rules, you should be able to just alter the request.Path [, Scheme , Host , QueryString ] in the context on its way through your middleware; something like below, and ensure your middleware runs early-enough in the pipeline:

internal class PathRewritingMiddleware
{
    private readonly RequestDelegate _next;

    public PathRewritingMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public Task Invoke(HttpContext context)
    {
        context.Request.Path = "elsewhere/" + context.Request.Path;
        return _next(context);
    }
}

That said, don't , as ASP.NET Core has already thought of all of this for you.
