TokenCore
TokenCore is a blockchain library. TokenCore provides the relatively consistent API that allows you to manage your wallets and sign transactions in BTC, ETH and EOS chains simultaneously.In addition, TokenCore introduces the concept of 'identity', you can use the same mnemonic to manage wallets on the three chains.
Installation
To install TokenCore, use CocoaPods and add this to your Podfile:
pod "TokenCore", git: "https://github.com/consenlabs/token-core-ios.git", branch: "master"
Run the Example
The example show how to manager the wallet and sign transaction, the eos sign will coming soon.
$ cd Example
$ pod install
Try the API
Create new Identity and derive the eth, btc wallets
// You should create or recover Identity first before you create other wallets
do {
var metadata = WalletMeta(source: .newIdentity)
metadata.network = Network.mainnet
metadata.segWit = .p2wpkh // .p2wpkh means that the derived btc wallet is a SegWit wallet
metadata.name = "MyFirstIdentity"
let (mnemonic, identity) = try Identity.createIdentity(password: TestData.password, metadata: metadata)
let ethereumWallet = identity.wallets[0]
let bitcoinWalelt = identity.wallets[1]
} catch {
print("createIdentity failed, error:\(error)")
}
Export Wallet
let prvKey = try WalletManager.exportPrivateKey(walletID: ethereumWallet.walletID, password: TestData.password)
print("PrivateKey: \(prvKey)")
let mnemonics = try WalletManager.exportMnemonic(walletID: ethereumWallet.walletID, password: TestData.password)
print("Mnemonic: \(mnemonics)")
let keystore = try WalletManager.exportKeystore(walletID: ethereumWallet.walletID, password: TestData.password)
print("Keystore: \(keystore)")
// output:
// PrivateKey: f653be3f639f45ea1ed3eb152829b6d881ce62257aa873891e06fa9569a8d9aa
// Mnemonic: tide inmate cloud around wise bargain celery cement jungle melody galaxy grocery
// Keystore: {"id":"c7575eba-3ae3-4cc3-86ba-2eb9c6839cad","version":3,"crypto":{"ciphertext":"7083ba3dd5470ba4be4237604625e05fa6b668954d270beb848365cbf6933ec5","mac":"f4f9ea8d42ff348b11fc146c396da446cc975309b3538e08a58c0b218bddd15d","cipher":"aes-128-ctr","cipherparams":{"iv":"db3f523faf4da4f1c6edcd7bc1386879"},"kdf":"pbkdf2","kdfparams":{"dklen":32,"c":10240,"prf":"hmac-sha256","salt":"0ce830e9f888dfe33c31e6cfc444d6f588161c9d4128d4066ee5dfdcbc5d0079"}},"address":"4a1c2072ac67b616e5c578fd9e2a4d30e0158471"}
SignTransaction
let signResult = WalletManager.ethSignTransaction(
walletID: String,
nonce: String,
gasPrice: String,
gasLimit: String,
to: String,
value: String,
data: String,
password: String,
chainID: Int
)
let signedTx = signResult.signedTx // This is the signature result which you need to broadcast.
let txHahs = signResult.txHash // This is txHash which you can use for locating your transaction record
Troubleshooting
For macOS 10.14 Mojave and Xcode 10, install /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg since Xcode command line tools don't install to /usr/include anymore.
TODO
- Test on Objective-C
- upgrade the
BigIntfrom 3.0 to 3.1

需要在一个vue-iview项目中引入一个轻量级富文本，并且结合iview的upload钩子函数实现自定义图片上传token验证 思路： 将图片先上传至服务器，再将图片链接插入到富文本中 图片上传的话可以使用element或者iview，这里我以iview举例 图片上传区域要隐藏，自定义vue-quill-editor的图片上传，点击图片上传时调用iview或者element的图片上传， 上传成功

刷新令牌是可用于获取新访问令牌的凭据。 与访问令牌的生命周期相比，刷新令牌的生命周期要长得多。 刷新令牌也可以过期，但是很长时间都很安静。 当前访问令牌过期或变为无效时，授权服务器向客户端提供刷新令牌以获取新的访问令牌。 下图说明了刷新过期的访问令牌的过程。 Step 1 - 首先，客户端通过授权授权向授权服务器进行身份验证。 Step 2 - 接下来，授权服务器验证客户端，验证授权授权并向客户端
