UI#

在 SDK 的基础上，我们也提供了 UI 界面。如果选择通过UI接入，若DApp运营在 Telegram内，则用户可以选择唤起移动端App钱包或者停留在Telegram并唤起欧易 Telegram Mini 钱包。

安装及初始化#

请确保更新OKX App到 6.92.0版本或以后版本，即可开始接入：

将 OKX Connect 集成到您的 DApp 中，可以使用 npm:

npm install @okxconnect/ui
npm install @okxconnect/aptos-provider

连接钱包之前，需要先创建一个可以提供UI界面的对象，用于后续连接钱包、发送交易等操作。

OKXUniversalConnectUI.init(dappMetaData, actionsConfiguration, uiPreferences, language)

请求参数

dappMetaData - object
- name - string: 应用名称，不会作为唯一表示
- icon - string: 应用图标的 URL。必须是 PNG、ICO 等格式，不支持 SVG 图标。最好传递指向 180x180px PNG 图标的 url。
actionsConfiguration - object
- modals - ('before' | 'success' | 'error')[] | 'all' 交易过程中的提醒界面展示模式，默认为'before'
- returnStrategy -string 'none' | ${string}://${string}; 针对app 钱包，指定当用户签署/拒绝请求时深层链接的返回策略，如果是在telegram中，可以配置tg://resolve
- tmaReturnUrl -string 'back' | 'none' | ${string}://${string}; Telegram Mini Wallet 钱包中，用户签署/拒绝请求时深层链接的返回策略，一般配置back,表示签名后关闭钱包，会自动展示出dapp；none 表示签名后不做处理；默认为back；
uiPreferences -object
- theme - Theme 可以是：THEME.DARK, THEME.LIGHT, "SYSTEM"
language - "en_US" | "ru_RU" | "zh_CN" | "ar_AE" | "cs_CZ" | "de_DE" | "es_ES" | "es_LAT" | "fr_FR" | "id_ID" | "it_IT" | "nl_NL" | "pl_PL" | "pt_BR" | "pt_PT" | "ro_RO" | "tr_TR" | "uk_UA" | "vi_VN"; , 默认为en_US

返回值

OKXUniversalConnectUI

示例

import { OKXUniversalConnectUI } from "@okxconnect/ui";

const universalUi = await OKXUniversalConnectUI.init({
    dappMetaData: {
        icon: "https://static.okx.com/cdn/assets/imgs/247/58E63FEA47A2B7D7.png",
        name: "OKX Connect Demo"
    },
    actionsConfiguration: {
        returnStrategy: 'tg://resolve',
        modals:"all"
    },
    language: "en_US",
    uiPreferences: {
        theme: THEME.LIGHT
    },
});

连接钱包#

连接钱包去获取钱包地址，作为标识符和用于签名交易的必要参数。

universalUi.openModal(connectParams: ConnectParams);

请求参数

connectParams - ConnectParams
- namespaces - [namespace: string]: ConnectNamespace ; 请求连接的必要信息，EVM系的key为"eip155"，Aptos系的key为"aptos" ，如果请求的链中，有任何一个链钱包不支持的话，钱包会拒绝连接；
  - chains: string[]; 链id信息,
  - defaultChain?: string; 默认链
- optionalNamespaces - [namespace: string]: ConnectNamespace; 请求连接的可选信息， EVM系的key为"eip155"，，Aptos系的key为"aptos" ，如果对应的链信息钱包不支持，依然可以连接；
  - chains: string[]; 链id信息,
  - defaultChain?: string; 默认链
- sessionConfig: object
  - redirect: string 连接成功后的跳转参数，如果是Telegram中的Mini App，这里可以设置为Telegram的deeplink: "tg://resolve"

返回值

Promise<SessionTypes.Struct | undefined>
- topic: string; 会话标识；
- namespaces: Record<string, Namespace>; 成功连接的namespace 信息；
  - chains: string[]; 连接的链信息；
  - accounts: string[]; 连接的账户信息；
  - methods: string[]; 当前namespace下，钱包支持的方法；
  - defaultChain?: string; 当前会话的默认链
- sessionConfig?: SessionConfig
  - dappInfo: object DApp 信息；
    - name:string
    - icon:string
  - redirect?:string, 连接成功后的跳转参数；

示例

var session = await universalUi.openModal({
    namespaces: {
        aptos: {
            chains: ["aptos:mainnet", // aptos mainnet
                  // "movement:testnet",// movement testnet
            ],
        }
    },
    sessionConfig: {
        redirect: "tg://resolve"
    }
})

判断钱包是否已连接#

获取当前是否有连接钱包;

返回值

boolean

示例

universalUi.connected();

准备交易#

首先创建一个OKXAptosProvider对象，构造函数传入OKXUniversalProvider

import { OKXAptosProvider } from "@okxconnect/aptos-provider";
let okxAptosProvider = new OKXAptosProvider(okxUniversalProvider)

获取钱包地址及publicKey#

okxAptosProvider.getAccount(chain);

请求参数

chain: string, 获取钱包地址的链id,不传则默认取第一个连接的aptos系地址

返回值

Object
- address: string 钱包地址
- publicKey: string 公钥

签名#

okxAptosProvider.signMessage(message, chain);

请求参数

message - object
- address?: boolean; // Should we include the address of the account in the message
- application?: boolean; // Should we include the domain of the DApp
- chainId?: boolean; // Should we include the current chain id the wallet is connected to
- message: string; // The message to be signed and displayed to the user
- nonce: string; // A nonce the DApp should generate
chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

Promise - object
- address: string;
- application: string;
- chainId: number;
- fullMessage: string; // The message that was generated to sign
- message: string; // The message passed in by the user
- nonce: string;
- prefix: string; // Should always be APTOS
- signature: string; // The signed full message

签单笔交易#

okxAptosProvider.signTransaction(transaction, chain);

请求参数

transaction - object | SimpleTransaction 交易数据对象
chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

Promise - Buffer 签名结果;

签多笔交易并上链#

okxAptosProvider.signAndSubmitTransaction(transactions, chain);

请求参数

transactions - object | SimpleTransaction 交易数据对象
chain: string, 请求签名执行的链，建议传递此参数；连接多条链时为必传参数；

返回值

Promise - string 交易hash;

示例

//签名消息
let data = {
    address:true,
    application:true,
    chainId:true,
    message:"Hello OKX",
    nonce:"1234"
}

let provider = new OKXAptosProvider(window.provider)
let message = await provider.signMessage(data, "aptos:mainnet")

//返回值 {"address":"0x2acddad65c27c6e5b568b398f0d1d01ebb8b55466461bbd51c1e42763a92fdfe","application":"http://192.168.101.13","chainId":"aptos:mainnet","fullMessage":"APTOS\naddress: 0x2acddad65c27c6e5b568b398f0d1d01ebb8b55466461bbd51c1e42763a92fdfe\napplication: http://192.168.101.13\nchainId: aptos:mainnet\nmessage: 123 签名测试!\nnonce: 1234","message":"123 签名测试!","nonce":"1234","prefix":"APTOS","signature":"0xef4e587f537b80a2f4e424079984b80e130c92d939a92225764be00ed36486521e8857b8a222de4023c5f4d2e9fd2f62c26ca8a43694660583c8a5d4328da303","verified":true}
