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 okxUniversalConnectUI = await OKXUniversalConnectUI.init({
dappMetaData: {
icon: "https://static.okx.com/cdn/assets/imgs/247/58E63FEA47A2B7D7.png",
