使用

// isMatch函数判断当前平台是否匹配
function isMatch(): boolean {
// ...
return true;
}

// Request类为平台特有的网络请求，必须实现post/upload/download三个public接口
export class Request extends AbstractSDKRequest {
// 实现post接口
public post(options: IRequestOptions) {
return new Promise(resolve=>{
// ...
resolve();
})
}
// 实现upload接口
public upload(options: IUploadRequestOptions) {
return new Promise(resolve=>{
// ...
resolve();
})
}
// 实现download接口
public download(options: IRequestOptions) {
return new Promise(resolve=>{
// ...
resolve();
})
}
}
// Storage为平台特有的本地存储，必须实现setItem/getItem/removeItem/clear四个接口
export const Storage: StorageInterface = {
setItem(key: string, value: any) {
// ...
},
getItem(key: string): any {
// ...
},
removeItem(key: string) {
// ...
},
clear() {
// ...
}
};
// WebSocket为平台特有的WebSocket，与HTML5标准规范一致
export class WebSocket {
constructor(url: string, options: object = {}) {
const socketTask: WebSocketInterface = {
set onopen(cb) {
// ...
},
set onmessage(cb) {
// ...
},
set onclose(cb) {
// ...
},
set onerror(cb) {
// ...
},
send: (data) => {
// ...
},
close: (code? : number, reason? : string) => {
// ...
},
get readyState() {
// ...
return readyState;
},
CONNECTING: 0,
OPEN: 1,
CLOSING: 2,
CLOSED: 3
};
return socketTask;
}
}

// genAdapter函数创建adapter实体
function genAdapter() {
const adapter: SDKAdapterInterface = {
// root对象为全局根对象，没有则填空对象{}
root: window,
reqClass: Request,
wsClass: WebSocket as WebSocketContructor,
localStorage: Storage,
// 首先缓存存放策略，建议始终保持localstorage
primaryStorage: StorageType.local,
// sessionStorage为可选项，如果平台不支持可不填
sessionStorage: sessionStorage
};
return adapter;
}

// 三者缺一不可
const adapter = {
genAdapter,
isMatch,
// runtime为标记平台唯一性的说明
runtime: 'wx_mp'
};
