Description

I am doing iOS development and monitoring network traffic using Proxyman.
I can see the network calls in Proxyman, suggesting I have the certificates set up correctly, however, I am trying to modify the response for an endpoint using scripts but the scripts aren't being triggered.

For context, the endpoint is a graphql endpoint and below is my script:

const file = require("mockdata.json");

async function onRequest(context, url, request) {
  // console.log(request);
  console.log(url);

  // 1. Extract the queryName from the request
  var queryName = request.body.query.match(/\S+/gi)[1].split('(').shift();

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

  // Done
  return request;
}

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

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

    // 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;
  }

  // Done
  return response;
}

I can confirm the script works because I am able to trigger the script by rerunning the request within Proxyman, however, I am unable to trigger the script from sending a request from my iOS app.

Any idea what the issue is? Smells like either an internal bug or a configuration issue.

Environment

App version: Proxyman 5.0.0
macOS version: macOS Sonoma 14.3.1
Xcode version: Xcode 15.1
Simulator version: Simulator 15.1

If you don't see any log, it means the Script URL doesn't match your URL.

Can you show me the script URL Rule you're using?

Your script is an old way to match with a GraphQL Query Name. If you're using v5.0.0, there is an easier way:

Call your GraphQL on iPhone -> Make sure you can see the traffic on Proxyman macOS
Right Click on this request -> Tools -> Scripting
✅ Proxyman automatically creates a matched rule with a given GraphQL QueryName.
Use your new script

const file = require("mockdata.json");

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

response.headers["Content-Type"] = "application/json";
    response.body = file;

  // Done
  return response;
}

Or you can map to a local file directly:

async function onResponse(context, url, request, response) {
  // console.log(response);
  response.headers["Content-Type"] = "application/json";
  response.bodyFilePath = "~/Desktop/my_response.json"
  
  // Done
  return response;
}

I was able to get it to work! However, not by importing my json file. I had to map the local file directly.
Thanks for your help!

@ben-codes-five Glad to know you made it. The Map Local Tool works fine too 👍

Reopening because a colleague of mine is having the same issue but can't seem to figure out what the issue is.

Similar to @ben-codes-five I'm unable to execute my script through requests made from simulator. Only on repeat requests through the proxyman window can I get the script to run. Heres my match:

@jmittelstaedt12 can you follow this steps:

Make a HTTP Request first on your iOS Simulator -> Verify you can see the request on Proxyman first
Right Click on this request -> Tools -> Scripting (No need to change any thing, it already works)
Re-sent your request again -> Check if you can see the console.log() from the Scripting ?

May I ask: Is your iOS app a native iOS app or React-Native ?
