A. 各コンポーネントのパブリックプロパティを使用してエラーメッセージを表示します。25
B. エラーメッセージを表示するには、window.alert() メソッドを使用します。23
C. <template>タグを使用して、インプレースエラーメッセージを表示します。24
D. Lightning Web コンポーネントを使用して、すべてのエラーを集約して表示します。
Question #2
次のコード スニペットを検討してください。
ジャワ
HttpRequest req = 新しい HttpRequest();
エンドポイントを 'https://TestEndpoint.example.com/some_path' に設定します。
req.setMethod('GET');
Blob headerValue = Blob.valueOf('myUserName' + ':' + 'strongPassword'); String authorizationHeader = 'BASIC ' + EncodingUtil.base64Encode(headerValue); req.setHeader('Authorization', authorizationHeader); Http http = new Http(); HTTPResponse res = http.send(req); コードを変更せずにエンドポイントと資格情報を変更するための柔軟性を追加するには、開発者が実行する必要がある 2 つの手順はどれですか?1
A. エンドポイントの URL を endPointURL.4 というカスタムラベルに保存します。
B. req.setEndpoint(Label.endPointURL); を使用します。
