msal typescript error 屬性'accessToken'在類型'void

JavaScript

下面的代碼為生成以下 TypeScript 錯(cuò)誤：response.accessTokenTS2339：屬性“accessToken”在類型“void |上不存在TokenResponse'.import * as Msal from '@azure/msal-browser'export async function getTokenPopup(request: Msal.TokenExchangeParameters) { return await auth.acquireTokenSilent(request).catch(async () => { return await auth.acquireTokenPopup(request).catch((error) => { console.log('login with popup failed: ', error) }) })}const getGraphDetails = async ( uri: string, scopes: Msal.TokenExchangeParameters, axiosConfig?: AxiosRequestConfig) => { return getTokenPopup(scopes).then((response) => { return callGraph(uri, response.accessToken, axiosConfig) })}當(dāng)檢查 TokenResponse 的 TS 定義時(shí)，它清楚地表明該屬性在對(duì)象上可用：accessTokenexport type TokenResponse = AuthResponse & { uniqueId: string; tenantId: string; scopes: Array<string>; tokenType: string; idToken: string; idTokenClaims: StringDict; accessToken: string; refreshToken: string; expiresOn: Date; account: Account;};我做錯(cuò)了什么？

只是一個(gè)關(guān)于你的，雖然你正在使用.我會(huì)這樣寫這段代碼：catchawait

import * as Msal from '@azure/msal-browser'

export async function getTokenPopup(request: Msal.TokenExchangeParameters) {

try {

return await auth.acquireTokenSilent(request);

} catch (error) {

return await auth.acquireTokenPopup(request);

}

const getGraphDetails = async (

uri: string,

scopes: Msal.TokenExchangeParameters,

axiosConfig?: AxiosRequestConfig

) => {

try {

const response = await getTokenPopup(scopes);

return callGraph(uri, response.accessToken, axiosConfig);

} catch (error) {

throw new Error("You could not get a token");

}

現(xiàn)在，為什么要進(jìn)入.有一種可能性，該函數(shù)將同時(shí)失敗，對(duì)于和。因此，該函數(shù)將引發(fā)錯(cuò)誤（或不返回任何內(nèi)容，具體取決于您的實(shí)現(xiàn)）。voidresponsegetTokenPopupacquireTokenSilentacquireTokenPopupgetTokenPopup

TypeScript 看到這一點(diǎn)，并添加一個(gè)類型以指示有可能無法獲得響應(yīng)。void
