How to set provider with access token in the "providerOrUrl" of the HDWalletProvider instance.

[ksanjaykumar1]

I have install security-plugin in the goQuorum private network, I have to send access token while communicating with the node.

I am not able to migrate contracts. I not able to set the correct provider thus failing to migrate. I confirmed network is working correctly by getting block number using web3js library.

here is my truffle-config.js

const HDWalletProvider = require('@truffle/hdwallet-provider');

const fs = require('fs');
const privateKey = fs.readFileSync('.private-key').toString().trim();

// creating provider 
require('dotenv').config();
let Web3 = require('web3');
const { TOKEN, BLOCKCHAIN_NODE } = process.env;
let HttpHeaderProvider = require('httpheaderprovider');
let headers = { Authorization: `Bearer ${TOKEN}` };
console.log(headers)

module.exports = {
 

  contracts_directory: './contracts/permissions',

  networks: {
    development: {
      provider: function () {
        return new HDWalletProvider({
          privateKeys: [privateKey],
          providerOrUrl: new Web3.providers.HttpProvider(BLOCKCHAIN_NODE,headers),
          chainId: 1337,
        });
      }, // replace with quorum node port you wish to connect to
      network_id: '*',
      type: 'quorum',
      gasPrice: 0,
      gas: 450000000,
    },
  },

  // Set default mocha options here, use special reporters etc.
  mocha: {
    // timeout: 100000
  },

  // Configure your compilers
  compilers: {
    solc: {
      version: '0.5.3', // Fetch exact version from solc-bin (default: truffle's version)
      // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
      // settings: {          // See the solidity docs for advice about optimization and evmVersion
      //  optimizer: {
      //    enabled: false,
      //    runs: 200
      //  },
      //  evmVersion: "byzantium"
      // }
    },
  },
};

I have also tried by creating provider with httpheaderprovider and passing it

const HDWalletProvider = require('@truffle/hdwallet-provider');

const fs = require('fs');
const privateKey = fs.readFileSync('.private-key').toString().trim();

// creating provider 
require('dotenv').config();
const { TOKEN, BLOCKCHAIN_NODE } = process.env;
let HttpHeaderProvider = require('httpheaderprovider');
let headers = { Authorization: `Bearer ${TOKEN}` };
const provider = new HttpHeaderProvider(BLOCKCHAIN_NODE, headers);


module.exports = {
  /**
   * Networks define how you connect to your ethereum client and let you set the
   * defaults web3 uses to send transactions. If you don't specify one truffle
   * will spin up a development blockchain for you on port 9545 when you
   * run `develop` or `test`. You can ask a truffle command to use a specific
   * network from the command line, e.g
   *
   * $ truffle test --network <network-name>
   */

  contracts_directory: './contracts/permissions',

  networks: {
    development: {
      provider: function () {
        return new HDWalletProvider({
          privateKeys: [privateKey],
          providerOrUrl: provider,
          chainId: 1337,
        });
      }, // replace with quorum node port you wish to connect to
      network_id: '*',
      type: 'quorum',
      gasPrice: 0,
      gas: 450000000,
      
    },
  },

  // Set default mocha options here, use special reporters etc.
  mocha: {
    // timeout: 100000
  },

  // Configure your compilers
  compilers: {
    solc: {
      version: '0.5.3', // Fetch exact version from solc-bin (default: truffle's version)
      // docker: true,        // Use "0.5.1" you've installed locally with docker (default: false)
      // settings: {          // See the solidity docs for advice about optimization and evmVersion
      //  optimizer: {
      //    enabled: false,
      //    runs: 200
      //  },
      //  evmVersion: "byzantium"
      // }
    },
  },


};

I am attaching the screenshots which I got.

1. By creating provider with Web3
   

2. By creating provider with httpheaderprovider
   

3. By passing just the url ( I got two different types of errors when i ran multiple times)
   
   

4. Confirmation that plugin is working and able to get blocknumber

Hi, httpheaderprovider is pretty old, and doesn't seem to have much support or usage. Have you tried passing an options object that Web3 expects? See their header tests, and docs

I think it worked correctly. But I am getting a new error which says "Error: net_version - access denied". I checked the version by using geth command line in the node and it says "1337" and I passed , chainId: 1337, in HDWalletProvider instance.

complete error message is

Error: net_version - access denied

Thank You. Now I able to migrate contracts. "net_version - access denied" error was due to "rpc://*_version" not being included in the scope of access token.
