Authentication
You will need authentication to Paras if you want to:
- 1.Create a publication
- 2.Edit collection
- 3.Create collections
- 4.Edit collections
- 5.Upload files
All direct function call to the smart contract would authentication with the near blockchain. To generate auth token please look at the following script,
1
const nearAPI = require('near-api-js')
2
const { Base64 } = require('js-base64')
3
4
const authToken = async (accountId, signer, networkId) => {
5
try {
6
const arr = new Array(accountId)
7
for (var i = 0; i < accountId.length; i++) {
8
arr[i] = accountId.charCodeAt(i)
9
}
10
const msgBuf = new Uint8Array(arr)
11
const signedMsg = await signer.signMessage(
12
msgBuf,
13
accountId,
14
networkId
15
)
16
const pubKey = Buffer.from(signedMsg.publicKey.data).toString('hex')
17
const signature = Buffer.from(signedMsg.signature).toString('hex')
18
const payload = [accountId, pubKey, signature]
19
return Base64.encode(payload.join('&'))
20
} catch (err) {
21
console.log(err)
22
return null
23
}
24
}

const main = async () => {
27
const config = {
28
networkId: 'testnet',
29
nodeUrl: 'https://rpc.testnet.near.org',
30
walletUrl: 'https://wallet.testnet.near.org',
31
appName: 'Paras Testnet',
32
contractName: `paras-token-v2.testnet`
33
}

try {
36
// Initializing nearAPI
37
// Login and init contract
38
const keyStore = new nearAPI.keyStores.UnencryptedFileSystemKeyStore(
39
`${process.env.HOME}/.near-credentials/`
40
)
41
42
const signer = new nearAPI.InMemorySigner(keyStore)
43
44
const connection = await nearAPI.connect({
45
deps: {
46
keyStore: keyStore,
47
},
48
...config,
49
})

51
const account_id = 'orang.testnet'
52
const account = await connection.account(account_id)
53
const authorizationHeader = await authToken(account_id, signer, config.networkId)
54

console.log(`Authorization Header : ${authorizationHeader}`)

} catch (err) {

throw err
