public JSONFileKeyStoreClient (File jsonFile)
公用方法
containsKey
public boolean containsKey (String key)
檢查金鑰庫是否包含特定金鑰的方法。
| 傳回 |
|---|
boolean |
如果指定的鍵存在，則傳回 true。 |
fetchKey
public String fetchKey (String key)
在金鑰庫中擷取指定金鑰的方法。
| 傳回 |
|---|
String |
鍵的 String 值。如果找不到鍵，則會傳回空值。 |
isAvailable
public boolean isAvailable ()
用於檢查是否有可用來通訊的有效金鑰庫。
| 傳回 |
|---|
boolean |
如果我們有有效的鍵值儲存庫，則傳回 true，否則傳回 false。 |
setKeyStore
public void setKeyStore (JSONObject keyStore)
用於設定 KeyStore 的輔助方法。用於測試。
受保護的方法
setKey
protected void setKey (String key,
String value)
將 key 對應至 value。等同於 mJsonKeyStore.put(key, value)。
