Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/872

Originally assigned to: @NghiaTranUIT on GitHub.

Description

If we import the file in the a Scripting, by using the following JS code:

const file = require("@users/myfile.json");

If the file is a large file, the script might run slowly.
The reason is that Proxyman would perform two tasks:

Read a local file in Swift and parse it to JS Object. Then passing to JS Environment
Getting the JS Object again and parse it to Swift Object

As a result, it might take more than 20 seconds to respond if a file is ~2Mb.

We should fix it.

Acceptance Criteria

Introduce request.bodyFilePath = "~/Desktop/file.json", so Proxyman could get the binary directly without parsing twice

Beta: https://proxyman.s3.us-east-2.amazonaws.com/beta/Proxyman_2.24.0_Better_File_Import_Scripting.dmg

// For request
request.bodyFilePath = "~/Desktop/image.png";

// For response
response.bodyFilePath = "~/Desktop/image.png";

Example:

function onResponse(context, url, request, response) {
 
  response.headers["Content-Type"] = "image/png";
  response.bodyFilePath = "~/Desktop/image.png";
 
  // Done
  return response;
}
