Bitcoin JSON RPC API - blockchain.info

经查，P2Pool使用的原始的Bitcoind RPC的方式调用，Eloipool已经改为使用新的JSON PRC方式（jgarzik写的有相应的python包）。

JSON RPC API Bitcoind compatible RPC api

My Wallet users can interact with their wallet using our JSON RPC api. It is intended to be fully compatible with the original Bitcoind RPC protocol however some method calls are not supported.

My Wallet可以使用JSON RPC api和钱包交互。它的目的是要与原来的Bitcoind RPC协议完全兼容，但不支持某些方法调用。

• No Blockchain Download - Save on bandwidth and disk space.
• No Need to run Bitcoind - Some VPS and shared hosting plans do not allow you to run custom processes
• Use Existing software - Most existing software that uses the bitcoind rpc calls will work transparently using blockhain.info
• Payment notifications
• Live synchronization with the web interface

     没有Blockchain下载 - 节省带宽和磁盘空间
     不需要运行Bitcoind - 一些VPS和共享主机计划不允许您运行自定义进程
     利用现有的软件 - 调用bitcoind RPC的现有的大多数软件将工作透明使用blockhain.info
     付款通知
     与Web接口实时同步

Authentication

-rpcuser Should be set to your wallet identifier. This is a 36 character random string which can be found on your wallet login page.
-rpcpassword Should be set to your main wallet password. If double encryption is enabled your second password will need to be set using walletpassphrase
-rpcport Should be set to 443 for https:// (when the -rpcssl is provided) or 80 for plain text http://
-rpcssl Set to use a secure connection (Recommended)

-rpcuser应设置为你的钱包标识符。这是一个36字符的随机字符串，在你的钱包的登录页面可以看到。
-rpcpassword应设置为您的主钱包密码。如果启用了双重加密你的第二个密码将需要使用walletpassphrase设置
-rpcport https方式请设置为443(同时需要设置-rpcssl)，http方式设置为80
-rpcssl设置为使用安全连接（推荐）

Security

This api is currently incompatible with two factor authentication and it must therefore be disabled. We HIGHLY recommend you enable double encryption which can be found on the My Wallet account details page.

这个API和目前authentication认证不兼容，因此它必须被禁用。我们强烈建议您启用双重加密，可以在My Wallet帐户详情页上找到。

If you will be accessing this API from a server with a static ip address is recommended you enable the IP Lock found in the Security Section of your My Wallet account.

如果你从一个静态IP地址的服务器调用这个API，建议您启用IP锁定(在My Wallet的Security Section)。

Unlike when using the javascript wallet transaction signing is conducted server side which means your private keys are shared with the server. However many operations such as fetching a balance and viewing transactions are possible without needing to decrypt the private keys. The is possible through the use of double encryption only when the second password is provided does the server have ability to access the funds in a wallet. For merchants who need to only receive transactions it maybe possible to never provide a second password.

这和使用javascript的钱包时交易签名不大一样，javascript版的私钥会传到server，等于是和服务器共享的。
然而，许多操作，如查看账户余额和查看交易是不需要解密私钥的。如果server需要第二密码才可以访问钱包的资金，可以使用双重加密。
对商家而言只需要接收tnx,所以永远也不需要提供第二密码。

If transactions can be delayed and are able to be manually reviewed we highly recommend you do this. Have your server construct a list of transactions which need to be made and every so often an admin can login and review the list - if the transactions look ok they can manually supply the second password with a short timeout (don't store the second password on your server if possible). When the admin provides a second password you can start a job to call sendmany.

如果交易可以被延迟，并能进行人工审查，我们强烈建议您这样做。如果服务器创建的有tnx的列表，管理员可以经常登陆查看列表。如果tnx看起来OK可以手工输入第二密码(如果可能不要把第二密码保存在服务器上)。当管理员提供了第二个密码，您就可以启动一个job调用sendmany

Notes

• An account is analogous for a label
• A label and bitcoin address are interchangeable i.e. any command which you can supply a bitcoin address you can substitute a label and visa versa
• Any parameters with default value e.g. (minConfirmations = 1) are optional
• 账户类似个label。
  label和比特币地址是可以互换的，任何提供BTC地址的命令都可以被替换为一个label,反之亦然。
  参数的默认值可选。

HTTP callbacks can be enabled in the notifications section of [Account Settings] in the web interface.

Host

The rpc host is rpc.blockchain.info. Plain http and SSL https are supported.

rpc主机地址是rpc.blockchain.info 普通http和https方式都可以

Connecting using Bitcoind

Bitcoind can be used as an RPC client for testing and debugging.

Bitcoind 可以作为RPC客户端使用，可用来测试或调试.

调用getinfo命令如下：

$ ./bitcoind -rpcconnect=rpc.blockchain.info -rpcport=443 -rpcssl -rpcuser=YourWalletIdentifier -rpcpassword=YourPassword getinfo
