rpc 上沒有專門的建立建立賬號的介面，eosjs上有
這本地測試環境中我使用裡eosjs 建立賬號，eosjs-cc 進行祕鑰的建立

eosjs 建立

核心程式碼片段如下：

 this.eosClient.transaction(tr => {
            tr.newaccount({
                creator: creator,
                name: name,
                owner: owner,
                active: active,
            });
 

            tr.buyram({
                payer: creator,
                receiver: name,
                quant: ram
            });
            tr.delegatebw({
                from: creator,
                receiver: name,
                stake_net_quantity: net,
                stake_cpu_quantity: cpu,
                transfer: 0
 

            });

        }, options).then(r => {
            console.log(r);
        }).catch(e => {
            console.log(e)
        });

這也就是下面指令的翻版版了。

cleos system newaccount eosio voter1 ${owerkey} ${activkey} \
--stake-net '10.000 SYS' --stake-cpu '10.000 SYS'  --buy-ram '10.000 SYS'

建立後返回的結構如下

RPC介面建立

我是在測試網路中進行測試的
我在eosio.system智慧合約中看到了這幾行：

 "structs": [
     ...
     {
      "name": "newaccount",
      "base": "",
      "fields": [
        {"name":"creator", "type":"account_name"},
        {"name":"name",    "type":"account_name"},
        {"name":"owner",   "type":"authority"},
        {"name":"active",  "type":"authority"}
      ]
    }
    ....
    {
      "name": "buyram",
      "base": "",
      "fields": [
         {"name":"payer", "type":"account_name"},
         {"name":"receiver", "type":"account_name"},
         {"name":"quant", "type":"asset"}
      ]
    },{
      "name": "delegatebw",
      "base": "",
      "fields": [
         {"name":"from", "type":"account_name"},
         {"name":"receiver", "type":"account_name"},
         {"name":"stake_net_quantity", "type":"asset"},
         {"name":"stake_cpu_quantity", "type":"asset"},
         {"name":"transfer", "type":"bool"}
      ]
    }
      ....
],

 "actions": [{
     "name": "newaccount",
     "type": "newaccount",
     "ricardian_contract": ""
   },
       .....
    {
      "name": "buyrambytes",
      "type": "buyrambytes",
      "ricardian_contract": ""
   },{
      "name": "buyram",
      "type": "buyram",
      "ricardian_contract": ""
   },{
      "name": "sellram",
      "type": "sellram",
      "ricardian_contract": ""
   },{
   {
      "name": "delegatebw",
      "type": "delegatebw",
      "ricardian_contract": ""
  },
       ....
]

由於prc 沒有直接的介面，使用eosjs 建立時可以反推需要將action進行序列化.簽名後再push transaction 這樣就能間接實現建立賬戶功能，我總結了一下，建立一共賬戶會用到的介面一共有

http://127.0.0.1:8888/v1/chain/get_info

返回：

{ server_version: '379cb1a9',
  chain_id: 'cec278a9dced800d9a695adc1e265ed11efa0ad8a70cdaac1eb65718bbe2434f',

  virtual_block_net_limit: 1048576000,
  block_cpu_limit: 99900,
  block_net_limit: 1048576 }

這裡會用到chain_id 和head_block_num

http://127.0.0.1:8888/v1/chain/get_block
返回：

{ timestamp: '2018-07-05T01:39:42.500',

  block_num: 1180202,
  ref_block_prefix: 2464184739 }

這裡會用到 block_num 和 ref_block_prefix

然後是常用的錢包操作：

http://127.0.0.1:8888/v1/wallet/create
http://127.0.0.1:8888/v1/wallet/import_key
引入已經認證的賬戶的私鑰到建立的錢包中去。
http://127.0.0.1:8888/v1/wallet/get_public_keys
檢視一下公鑰是否正確
http://127.0.0.1:8888/v1/wallet/unlock

然後就是分別序列化 action ：newaccount、buyram、delegatebw
http://127.0.0.1:8888/v1/chain/abi_json_to_bin
newaccount 的data:

{
        code: "eosio",
        action: "newaccount",
        args: {
            creator: "acooleosgeek",
            name: "rpccreate111",
            owner: {
                threshold: 1,
                keys: [
                    {
                        key: "EOS6DA4UQnqKy46Z34WyDpUcPHQRuh3AZry9NY46Fuu4Uddt1zrvj",
                        weight: 1
                    }
                ],
                accounts: [],
                waits: []
            },
            active: {
                threshold: 1,
                keys: [
                    {
                        key: "EOS6DA4UQnqKy46Z34WyDpUcPHQRuh3AZry9NY46Fuu4Uddt1zrvj",
                        weight: 1
                    }
                ],
                accounts: [],
                waits: []
            }
        }
    }

buyram 的 data

    {
        code: "eosio",
        action: "buyram",
        args: {
            payer: "acooleosgeek",
            receiver: "rpccreate111",
            quant: "20.0000 SYS",
        }
    }

delegatebw的data

 {
        code: "eosio",
        action: "delegatebw",
        args: {
            from: "acooleosgeek",
            receiver: "rpccreate111",
            stake_net_quantity: "20.0000 SYS",
            stake_cpu_quantity: "20.0000 SYS",
            transfer: 0,
        }
    }

然後就是簽名操作了
http://127.0.0.1:8888/v1/wallet/sign_transaction
data的格式如下

{
        ref_block_num: '1046911',//block_num
        ref_block_prefix: "515467051",//對應 ref_block_prefix
        expiration: "2018-07-4T09:28:49", //注意設定超時

                permission: "owner" 
            }],
            data: "00956298aa482932104250d9a88b50bd01000000010002ae152701b13d2f5e80aad26a332392d483213a5529f1bed8f7f7d59b24282c530100000001000000010002ae152701b13d2f5e80aad26a332392d483213a5529f1bed8f7f7d59b24282c5301000000"
        }, {

            }],
            data: "00956298aa482932104250d9a88b50bd400d0300000000000453595300000000400d030000000000045359530000000000"
            },{
            account: "eosio",

            authorization: [{
                actor: "acooleosgeek",
                permission: "owner"
            }],
            data: "00956298aa482932104250d9a88b50bd400d0300000000000453595300000000"
        }],
        signatures: []
    },
        ["EOS6DA4UQnqKy46Z34WyDpUcPHQRuh3AZry9NY46Fuu4Uddt1zrvj"], // acooleosgeek 的公鑰 必須import到錢吧
        "cec278a9dced800d9a695adc1e265ed11efa0ad8a70cdaac1eb65718bbe2434f" //區塊id
    ]

簽完名 推送交易
http://127.0.0.1:8888/v1/chain/push_transaction

push_transaction 的data格式如下：

{
        signatures: ["SIG_K1_KVo7keubHWn5sQ3P2dnxzuW4Ehs7JYT6ChDs92JvQSBQcpQAXro8VixzNY18x56GisG5gzfSQWcyE89cr9qpCtepZrhdXV"],

            max_cpu_usage_ms: 0,
            transaction_extensions: [],
            context_free_data: [],
            actions:
                [{
                    account: "eosio",
                    name: "newaccount",
                    authorization: [{
                        actor: "acooleosgeek",
                        permission: "owner"
                    }],
                    data: "00956298aa482932104250d9a88b50bd01000000010002ae152701b13d2f5e80aad26a332392d483213a5529f1bed8f7f7d59b24282c530100000001000000010002ae152701b13d2f5e80aad26a332392d483213a5529f1bed8f7f7d59b24282c5301000000"
                }, {
                    account: "eosio",
                    name: "delegatebw",
                    authorization: [{
                        actor: "acooleosgeek",
                        permission: "owner"
                    }],
                    data: "00956298aa482932104250d9a88b50bd400d0300000000000453595300000000400d030000000000045359530000000000"
                }, {
                    account: "eosio",
                    name: "buyram",
                    authorization: [{
                        actor: "acooleosgeek",
                        permission: "owner"
                    }],
                    data: "00956298aa482932104250d9a88b50bd400d0300000000000453595300000000"
                }],
        }
    }

最後就會返回200了：
