Multiple Part Forms

[NghiaTranUIT]

Description

• Sample File:

Acceptance Criteria

• If the request is a multipart request (Check the Content-Type header: If it starts with multipart/form-data)
• Show the Multipart tab on the Request Tab (Don't implement on the Response Tab)
• Display Multiple part as a table view

• Make sure the Body Tab renders correctly

• Able to export the FILE to Desktop -> Export with filename + extension -> Able to open it without any error.

Logic

• Implement the class MultipartService to handle the parser
• Use this lib: https://www.npmjs.com/package/parse-multipart-data
• Write Unit Test to try to parse a given Body (Multipart includes text, and Binary File) -> Get data correctly.

How to test

• Use Insomnia or Postman to make a Multipart request
• Use multiple Texts and Files for testing
• Make sure Proxyman can show the Multipart correctly.

Update requirement

• Show this view if the total body is over 5Mb. If it's < 5Mb, show the Multipart view as usual

• Verify that if body > 5 Mb, we don't process the Multipart data, because it can cause performance issues (app hangs, freeze, ...)

• Use a Save and "Show anyway" button. Remove the "Open With" button.

• Save: Select a folder -> Proxyman will export ALL parts to a selected folder, each part should have the name by format:

  1. If this part has the filename column -> Use this filename
  2. If this part doesn't have the filename -> Use generic name: Part_${index}

• Show anyway will show the Multipart view as usual. This selection doesn't persist, it will reset to FALSE if we select new flow.

• This new requirement will fix this issue: https://github.com/ProxymanApp/Proxyman/issues/1828

How to test with large data

1. Make a multipart with Insomnia / Postman with 3 parts: 2 first parts are an Video/Image ~20Mb, and the last part is a JSON string.
2. Open it on Proxyman -> Verify the "Body over 5Mb ..." is displayed ✅ -> Verify we don't proceed the Multipart Data.
3. Click on the "Save" button -> Select the folder: test in the Desktop. Verify We have 3 files are exported ✅ (2 files are image/video, can open it, and the last file is a JSON text)
4. Click on the Show anyway button -> Show the Multipart Preview as usual
