@mihoyo-kit/api
This package provides the common request method for miHoYo API and utility methods like getDS
and getDS2
.
DS
const enum APIClientType {
IOS = 1,
ANDROID = 2,
WEB = 4, // pc
WEBVIEW = 5, // webview in android / ios app
}
interface DSOptions {
client_type: MixedValuesOfEnum<APIClientType>; // client type in HTTP request header
app_version: string; // HoYoLab's version, miHoYo uses it and `client_type` to decide the actual salt
channel?: string; // for HoYoLab's native requests in CN, it'll be `miyousheluodi`
device_id?: string; // some miHoYo API needs the device id, which usually in UUID format or a hexed md5 result
salt?: string; // custom salt, skipping the internal salt resolve procedure
ds2?: boolean; // whether to use the `getDS2` algorithm or not, default false
}
function getDS(): string;
function getDS(options: DSOptions): string;
function getDS(client_type: MixedValuesOfEnum<APIClientType>, app_version?: string): string;
function calculateDS(salt: string): string;
type DS2Param = string | Record<string, string | number | boolean | null | undefined>;
function getDS2(body: DS2Param, query: DS2Param | URLSearchParams, options?: DSOptions): string;
function getDS2(body: DS2Param, query: DS2Param | URLSearchParams, client_type: MixedValuesOfEnum<APIClientType>, app_version?: string): string;
function calculateDS2(salt: string, body: string, query: string): string;
The getDS
and getDS2
utility function automatically resolve the proper salt, but you need to provide the correct client_type
and app_version
(defaults to the latest recorded version of HoYoLab).
Request Utility
interface RequestOptions {
method?: 'GET' | 'POST' | 'PUT' | 'PATCH' | 'DELETE'; // default: GET
prefixUrl?: string;
searchParams?: string | URLSearchParams | Record<string, string | number | boolean | null | undefined>; // Query string that will be added to the request URL, this will override the query string in url
resolveUrl?: (url: string, options?: RequestOptions) => string; // custom url translator, runs after getDS/getDS2 and before actual HTTP request
cookieJar?: PromiseCookieJar; // tough-cookie's CookieJar instance, `options.headers.cookie` will be overridden if provided
body?: string | Buffer | Blob | BufferSource | FormData | URLSearchParams | ReadableStream<Uint8Array>; // raw HTTP request body
form?: Record<string, any>; // will be converted to a query string and set `Content-Type` to `application/x-www-form-urlencoded`
json?: Record<string, any>; // will be stringified using `JSON.stringify` and set `Content-Type` to `application/json`
headers?: Headers | Record<string, string | number>;
signal?: AbortSignal;
timeout?: number; // in milliseconds, default 0, which means no timeout
followRedirect?: boolean; // default: true
throwHttpErrors?: boolean; // default: true
resolveBodyOnly?: boolean; // default false, when set to true the promise will return the Response body instead of the Response object
responseType?: 'text' | 'json' | 'buffer' | 'arraybuffer' | 'formdata'; // no default, which will leave the response body unread
// DSOptions
ds?: DSOptions;
// flattened DSOptions
client_type?: MixedValuesOfEnum<APIClientType>;
app_version?: string;
channel?: string;
device_id?: string;
salt?: string;
ds2?: boolean;
}
function request<T = unknown>(url: string | URL, options?: RequestOptions): Promise<Response | T>;
This package currently provides 2 implementations of request
function:
@mihoyo-kit/api/lib/request-browser
Uses browser's Fetch API. If you want to support old browsers, please import the polyfill (eg.
whatwg-fetch
) by yourself.Due to the limitation of browser,
options.headers.cookie
andoptions.cookieJar
will be silently ignored.If the function runs on the normal web page, or the browser extension without host permission, you may need to set up a proxy server, set
document.cookie
in client side, and request with optioncredentials: 'same-origin'
orcredentials: 'include'
.@mihoyo-kit/api/lib/request-node
Uses
undici
module to make HTTP requests, andabort-controller
to make it cancelable.To make
fetch
work, your Node's version should NOT less than 16.5.0If you're using npm below
7.0.0
or Yarn and other package managers, you may need to addundici
,abort-controller
as your project's dependencies explicitly.
IMPORTANT
This package uses Conditional Exports to decide which implementation to use, your JS runtime or bundler should support the following features:
If you're using Rollup or Vite to bundle your App, be sure to import
@rollup/plugin-node-resolve
in bundler's configuration, and its version should at least13.0.0
.
Example usage:
import { request, APIClientType } from '@mihoyo-kit/api';
interface PCBannerResult {
banners: Array<{ image: string, path: string }>;
}
const res = await request<PCBannerResult>('https://bbs-api.mihoyo.com/misc/wapi/getPCBanner?gids=2', {
client_type: APIClientType.WEB,
app_version: '2.11.0', // <== if omitted, it'll use the latest recorded version
responseType: 'json',
resolveBodyOnly: true,
});
console.log(res); // { banners: [...] }
