驗證內部權杖
若要驗證內部權杖的內容，您的服務應依照 JWT RFC 7516 中定義的標準驗證 JWT 的簽章。 此範例權杖在 Partner Center 中設定為使用 JKU 簽章驗證，因此內部權杖的標頭會提供下列內容：{
"alg": "PS256",
"kid": "8a19440f-6553-4e5a-9db8-c2de462f9ae4",
"jku": "https://xsts-keys.auth.xboxlive.com/keys",
"typ": "JWT"
}
kid 值會識別用來產生簽章的特定 XBOX Live 簽署金鑰。
jku 值指向可下載公開金鑰並用來驗證簽章的 URL。
如果 jku 的網域名稱不是 “xsts-keys.auth.xboxlive.com”，則不應信任該權杖。
建議在執行階段快取金鑰，因為簽署金鑰經常變更。
這也可讓您的服務具有復原能力，並能在金鑰即時更新時處理取得新金鑰，而不會停機或需要維護。
如果您使用現有的 JWT 開放原始碼解決方案，當您將 JKW 公開金鑰傳入 JWK 解碼 API 時，會自動完成簽章驗證。
驗證簽章之後，您的服務就可以信任憑證及其中的資料是真實的。
如需 XBOX Live 簽署 JWK 和 XBOX Live 簽署憑證之內部權杖驗證的詳細資訊，請參閱內部權杖標頭和簽章驗證
識別權杖中的正確使用者
權杖會包含在用戶端上建立權杖時，所有已主動登入之 XBOX Live 使用者的使用者身分識別。 因此，您的服務需要使用 HTTP 授權標頭中的使用者雜湊值，並在使用者身分識別中找到相符的ush 值。
對於此範例權杖，Authorization 標頭的使用者雜湊為 18026470712427541036。
由此我們可以看到，宣告是針對此使用者雜湊，也就是玩家代號 2 Dev 079574836。
雖然此權杖在權杖宣告中只有一個使用者身分識別，我們仍應驗證它是否與標頭中的使用者雜湊相符。
