Wallet file not specified (must request wallet RPC through /wallet/ uri-path). BitcoinJSONRPCClient異常、及其他異常

1、異常信息 Wallet file not specified (must request wallet RPC through /wallet/<filename> uri-path)

Exception in thread "main" wf.bitcoin.javabitcoindrpcclient.BitcoinRPCException: RPC Query Failed (method: getbalance, params: [], response code: 500 responseMessage Internal Server Error, response: {"result":null,"error":{"code":-19,"message":"Wallet file not specified (must request wallet RPC through /wallet/<filename> uri-path)."},"id":"1"}

Process finished with exit code 1

原因：由於bitcoin core 客戶端里面創建了多個錢包，java連接的時候未指明使用某個錢包而產生的

解決： URL url = new URL("http://user:password@127.0.0.1:18332");  在連接后面加上錢包名稱

Eq: 我有個錢包名叫：lpz

那么連接就因該是: URL url = new URL("http://user:password@127.0.0.1:18332/wallet/lpz"); 在連接后面加上錢包名稱

錢包里面有個默認的錢包，連接是就不加名稱 URL url = new URL("http://user:password@127.0.0.1:18332/wallet/");

2、異常信息 Error: Please enter the wallet passphrase with walletpassphrase first.

Exception in thread "main" wf.bitcoin.javabitcoindrpcclient.BitcoinRPCException: RPC Query Failed (method: dumpprivkey, params: [2N1y1DGtXUbajM5SWyo9yRgiWAqQcPUyVEA], response code: 500 responseMessage Internal Server Error, response: {"result":null,"error":{"code":-13,"message":"Error: Please enter the wallet passphrase with walletpassphrase first."},"id":"1"}

Process finished with exit code 1

原因：調用dumppivkey (獲取私鑰) 的時候需要先輸入錢包密碼，沒有輸入密碼就調用此方法拋出的異常

解決：在調用獲取私鑰方法之前輸入錢包密碼：bitcoinClient.walletPassPhrase("你的錢包密碼",超時時間);

Eq:

 bitcoinClient.walletPassPhrase("lpz",60);
 String addressPrivateKey=bitcoinClient.query("dumpprivkey","2N1y1DGtXUbajM5SWyo9yRgiWAqQcPUyVEA").toString();
 logger.info("獲取地址私鑰："+ addressPrivateKey);

還有其它的方法也是需要輸入密碼的，主要是看它提示什么，或者你在bitcoin core控制台線調用一下方法
