scripting no working

[trycatchx]

Proxyman version

Proxyman 2.5.1

macOS Version?

mac 10.15.5

I want to unzip my http Response
step1:
I use pako.js ，and put it into libs folder
step2:
i create Pako.js file put into addons folder, is to expose inflate function

// Pako.js
const pako = require('@libs/pako.js');

const inflate = (input) => {
    return pako.inflate(input);
};
exports.inflate = inflate;

step3:
open scripting and enter the following code :

// Addons List: https://docs.proxyman.io/scripting/addons
const { inflate } =  require("@addons/Pako.js");
function unzip( b64Data){
    var strData   = b64Data;
    // Convert binary string to character-number array
    var charData  = strData.split('').map(function(x){return x.charCodeAt(0);});
    // Turn number array into byte-array
    var binData   = new Uint8Array(charData);
    // // unzip
    var data    = inflate(binData);
    // Convert gunzipped byteArray back to ascii string:
    strData   = String.fromCharCode.apply(null, new Uint16Array(data));
    return decodeURIComponent(strData);
}


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

  console.log('begin');
   if(response.body != null) {
     var jsonString = JSON.stringify(response.body);
    console.log('2222'+unzip(jsonString));
  }
 
  // Done
  return response;
}

Console output:
begin
❌Error: incorrect header check
❌Error: Could not convert JSvalue to Dictionary. Please make sure the return value is a JS dictionary (Object)

can someone please tell me what went wrong ?

Let me investigate why it doesn't work in your case.

Btw, can you add this log on the onResponse func? I would like to see the Content-Type and what the value of body is @zhangchaojiong

console.log(response.headers)
console.log(response.body)

[NghiaTranUIT]

Btw, It's better than I should provide a built-in addon for unzip/zip tasks.

[NghiaTranUIT]

Thanks. Since your Content-Type is text/plain, so the response.body is a string, not JSON Object. Thus, you don't need to convert to JSON String (JSON.stringify).

[NghiaTranUIT]

Please try to remove this line and pass the response.body to the unzip() function

You can use check the type of typeof(response.body) to see what is the type before working on 👍

Thanks Reply @NghiaTranUIT
typeof(response.body) is string

i remove this line JSON.stringify

i alway get the same result :

begin
❌Error: incorrect header check 
❌Error: Could not convert JSvalue to Dictionary. Please make sure the return value is a JS dictionary (Object)

Then, I changed the code to this：

const { inflate } =  require("@addons/Pako.js");
function unzip( ){
  var b64Data   = 'H4sIAAAAAAAAAJ3UMQ7CMAwF0KugP2ewEzdpcxXUAbWAOiHUMqCqdyeVQAobfGXIYL8hP5ZXnEdkeNEk6vUgXTbLonC4zMjHFY/5Wm511ekdTsOCLKVp2rlIKOA2jTuBot/cr7BhobEwsbAloY8kDGyqoQ5H/oHsdwQ21cCmaspCz0L2jcYOgLHhNGw4TT1yVmBpuS9PZHWY35siqnxvimEvpE9FY4peQhfbhO0FDnuFqWAEAAA=';
    var strData   =b64Data ;
    // Convert binary string to character-number array
    var charData  = strData.split('').map(function(x){return x.charCodeAt(0);});
    // Turn number array into byte-array
    var binData   = new Uint8Array(charData);
    // // unzip
    var data    = inflate(binData);
    // Convert gunzipped byteArray back to ascii string:
    strData   = String.fromCharCode.apply(null, new Uint16Array(data));
    return decodeURIComponent(strData);
}


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

  console.log('begin');
  
   unzip();
  
 
  // Done
  return response;
}

Console output:

begin
❌Error: incorrect header check 
❌Error: Could not convert JSvalue to Dictionary. Please make sure the return value is a JS dictionary (Object)

I guess, is pako.js not successfully linked?

[NghiaTranUIT]

Let me see 👍

[trycatchx]

@NghiaTranUIT I made it work

this is my code:

// Addons List: https://docs.proxyman.io/scripting/addons
const { inflate } =  require("@addons/Pako.js");

// Decode Baes64
const { base64Decode } = require("@addons/Base64Decode.js");



function unzip( ){
  var b64Data   = 'eNrLVMjJL0tVqMwvBQATqAO9';
    var strData   =  base64Decode(b64Data) ;
    // Convert binary string to character-number array
    var charData  = strData.split('').map(function(x){return x.charCodeAt(0);});
    // Turn number array into byte-array
    var binData   = new Uint8Array(charData);
    // // unzip
    var data    = inflate(binData, {"to":"string"});
    // Convert gunzipped byteArray back to ascii string:
    strData   = String.fromCharCode.apply(null, new Uint16Array(data));
    return decodeURIComponent(strData);
}


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

  console.log('begin');
  
  
     console.log('begin1'+ unzip());
 
  // Done
  return response;
}

Console output:

----------------------------------
19:43:20.257: [onResponse] with Request ID=8185
begin
begin1i love you
19:43:20.273 onResponse() is executed!

[NghiaTranUIT]

Glad to hear that 😄

I'm not sure why var b64Data = "H4sIAAAAAAAAAwXB2w0AEBAEwFbWl2Y0IW4jQmziPNo3k6TuGK0Tj/ESVRs6yzkuHRnGIqPB92qzhg8yp62UMAAAAA=="; doesn't work. The same value is working on the web

[trycatchx]

btw, Can you provide a built-in addon for unzip/zip tasks? Make work easier!

[NghiaTranUIT]

Sure, I will open the ticket for it 👍

[trycatchx]

@NghiaTranUIT thx!
