[luat-truong-ts]

Expected Behavior

• Multipart form data
• Form data
  Expect proxy success

Actual Behavior

Observe the error http: ContentLength=32 with Body length 0

Steps to Reproduce the Problem

Using stub using proxy and matching body with content type:

• Form data

Potential root cause

SincematchJSONBody using readRequestBody function which return a new reader, matchMultiplePart and matchURLEncodedBody use ParseMultipartForm of HTTP package directly -> This lead to original request body is read once.

Suggest solution

• Transform request.Body to some struct implement the interface io.Seeker and call Seek(0,0) to reset the reader for each time call to matchBody
