描述

Expected Behavior

A multipart/form-data http POST request is redirected to the desired endpoint.

Actual Behavior

An error 404 - not found http response is given.

Description

I won't include steps to reproduce the problem etc, because I'm pretty sure the feature is just not implemented (yet - or intentional).

Question

Is rerouting a file upload using multipart/form-data desired functionality, or is in an intentionally left out thing? I could imagine you'd not want to reroute such a file upload because of the overhead - why not just upload the file directly to the API? However, if the overhead is as little as the normal http requests are (about 1 ms), then I'd think it would be preferable to support multipart/form-data http post requests in reroutes.

Edit: The reason I'm certain that I haven't just incorrectly configured the reroute, is as follows: When I send the request with no file in the parameter, the reroute works and gets into my other API. When I send the request with a file in the parameter, error 404 occurs, thrown by Ocelot presumably.

研究方向
The issue asks whether multipart/form data routing is intentionally unsupported in Ocelot. To implement, examine the routing middleware in Ocelot (e.g., Ocelot.Middleware.MultipartBodyMiddleware or similar) and how it handles different content types. Check if there are any existing PRs or discussions addressing multipart support. The maintainer has not responded, so clarifying the intended behavior is the first step. Then, modify the routing logic to forward multipart requests to the downstream service.
