No way to filter on request body

[rsaunders100]

Proxyman version? (Ex. Proxyman 1.4.3)

Version 2.16.1 (21610)

We have a universal endpoint, the request body changes not the URL so there is no way to filter on a particular request for rewrite or a breakpoint.

Hi @rsaunders100, we'd not introduce the "Request Body Matching" because it could make the UI more complicated.

To resolve it, I'd highly suggest using ReWrite. Here is an example to solve your cases:

1. Create a scripting rule (URL = https://example.com)
2. Use the following script to match the Request and then mapping the Response (Please read the comment)

// Import file from More Button -> Import JSON or Other files 
const file = require("@users/B02D96D5.default_message_32E64A5B.json");

function onRequest(context, url, request) {

  // 1. Extract the name from Request Body
  // request.body is a JSON, so you can get whatever you want
  var queryName = request.body["name"]

  // 2. Save to sharedState
  sharedState.queryName = queryName

  // Done
  return request;
}

function onResponse(context, url, request, response) {

  // 3. Check if it's the request we need to map
  if (sharedState.queryName == "getUser") {

    // 4. Import the local file by Action Button -> Import
    // Get the local JSON file and set it as a body (like Map Local)
    response.headers["Content-Type"] = "application/json";
    response.body = file;

    // Or change header, status code, body like Breakpoint Tool
    // Example: https://docs.proxyman.io/scripting/snippet-code#2-common-on-request-and-response
  }

  // Done
  return response;
}

3. Profit 😄

Notes

• By using the Scripting tool, You can write JS code to mimic the behavior of Map Local and Breakpoint programmatically
• This approach is using for graphQL (Blog: https://proxyman.io/blog/2021/01/How-To-Map_Response_For_GraphQL_Requests.html)

Thanks! Very helpful.

Is the sharedState variable specific to the request response pair? Or is it global for all requests?

[NghiaTranUIT]

Yes, it's only available in this request-response pair (not global variable for all requests). You can read more at https://docs.proxyman.io/scripting/environment-variables @rsaunders100
