cleos包含所有命令的文档。有关cleos已知的所有命令的列表，只需简单地运行它，不带任何参数：
$ cleos
ERROR: RequiredError: Subcommand required
Command Line Interface to EOSIO Client
Usage: cleos [OPTIONS] SUBCOMMAND
Options:
-h,–help 打印帮助信息并且退出
-u,–url TEXT=http://localhost:8888/
nodeos 运行的http/https URL
–wallet-url TEXT=http://localhost:8888/
keosd运行的 http/https URL
-v,–verbose 输出对错误的详细操作
子命令:

net 与本地p2p网络连接进行交互
wallet 与本地钱包互动
sign 签署交易
push 将任意事务推送到区块链
multisig Multisig合同命令
system 将eosio.system合约行为发送到区块链。
所有子命令
要获得有关任何特定子命令的帮助，请使用无参数运行它：
$ cleos create
ERROR: RequiredError: Subcommand required
Create various items, on and off the blockchain
Usage: ./cleos create SUBCOMMAND
Subcommands:
key Create a new keypair and print the public and private keys
account Create a new account on the blockchain
producer Create a new producer on the blockchain
$ cleos create account
ERROR: RequiredError: creator
Create a new account on the blockchain
Usage: ./cleos create account creator name OwnerKey ActiveKey
Positionals:
creator TEXT The name of the account creating the new account

OwnerKey TEXT The owner public key for the account
ActiveKey TEXT The active public key for the account
链接节点
这会将您连接到本地节点
$ cleos -u localhost:8889
$ cleos --url localhost:8889
您还可以调整节点参数以连接到其他节点，例如公共测试网
$ cleos -H test1.eos.io -p 80
注意 你需要在每个请求中包含-H和-p参数来解决问题
查询区块链状态
$ cleos get info

“participation_rate”: “1.00000000000000000”

通过transaction_id获取交易
通过在nodeos中加载account_history_api_plugin，我们可以使用transaciton_id查询特定事务
$ cleos get transaction eb4b94b72718a369af09eb2e7885b3f494dd1d8a20278a6634611d5edd76b703

我们也可以查询某个账户从最近一个账户开始执行的交易清单
$ cleos get transactions inita
[
{
“transaction_id”: “eb4b94b72718a369af09eb2e7885b3f494dd1d8a20278a6634611d5edd76b703”,

创建钱包
创建钱包时不指定名称，钱包将使用名称’default’
$ cleos wallet create
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
“PW5JD9cw9YY288AXPvnbwUk5JK4Cy6YyZ83wzHcshu8F2akU9rRWE”
您可以在命令中添加-n ${wallet_name}命名钱包
$ cleos wallet create -n second-wallet
Creating wallet: second-wallet
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
“PW5Ji6JUrLjhKAVn68nmacLxwhvtqUAV18J7iycZppsPKeoGGgBEw”
钱包列表
列表钱包命令将列出每个钱包状态的所有钱包，*符号表示钱包当前已解锁。
$ cleos wallet list
Wallets:
[
“default *”,
“second-wallet *”
]
导入密钥
注意: 如果您没有持有账户密钥，则需要使用create account命令先创建账户密钥。
$ cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
列出钱包密钥
这将列出公钥中存储在钱包中的所有密钥。
$ cleos wallet keys
[[
“EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV”,
“5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3”
]
]
锁钱包
$ cleos wallet lock -n second-wallet
Locked: ‘second-wallet’
注意锁定的钱包在列表中没有*符号
$ cleos wallet list
Wallets:
[
“default *”,
“second-wallet”
]
解锁钱包
要解锁它，请指定创建钱包时获得的密码
$ cleos wallet unlock -n second-wallet --password PW5Ji6JUrLjhKAVn68nmacLxwhvtqUAV18J7iycZppsPKeoGGgBEw
Unlocked: ‘second-wallet’
打开钱包
$ cleos wallet open
Wallets: [
“default”
]
$ cleos wallet open -n second-wallet
Wallets: [
“default”,
“second-wallet”
]
创建密钥
为了创建一个帐户，你需要两个新的密钥：所有者和主动。您可以要求cleos为您创建一些钥匙：
这将是你的Owner Key，
$ cleos create key
public: EOS4toFS3YXEQCkuuw1aqDLrtHim86Gz9u3hBdcBw5KNPZcursVHq
private: 5JKbLfCXgcafDQVwHMm3shHt6iRWgrr9adcmt6vX3FNjAEtJGaT
这将是你的主动键，
$ cleos create key
public: EOS7d9A3uLe6As66jzN8j44TXJUqJSK3bFjjEEqR4oTvNAB3iM9SA
private: 5Hv22aPcjnENBv6X9o9nKGdkfrW44En6z4zJUt2PobAvbQXrT9z
注意：cleos不保存生成的私钥。
创建帐号
您将需要您的EOS密钥才能创建帐户，您必须在Ethereum网络上注册您的EOS密钥，或者您可以使用创建密钥功能创建一组新密钥
$ cleos create account inita tester EOS4toFS3YXEQCkuuw1aqDLrtHim86Gz9u3hBdcBw5KNPZcursVHq EOS7d9A3uLe6As66jzN8j44TXJUqJSK3bFjjEEqR4oTvNAB3iM9SA

}
],

}
],
“output”: [{
“notify”: [],
“sync_transactions”: [],
“async_transactions”: []
}
]
}
}
子帐户
要检查由帐户（控制帐户）创建的子帐户
$ cleos get servants inita
{
“controlled_accounts”: [
“tester”
]
}
检查帐户余额
$ cleos get account tester
{
“name”: “tester”,
“eos_balance”: 0,
“staked_balance”: 1,
“unstaking_balance”: 0,
“last_unstaking_time”: “1969-12-31T23:59:59”,
“permissions”: [{
“name”: “active”,
“parent”: “owner”,
“required_auth”: {
“threshold”: 1,
“keys”: [{
“key”: “EOS7d9A3uLe6As66jzN8j44TXJUqJSK3bFjjEEqR4oTvNAB3iM9SA”,
“weight”: 1
}
],
“accounts”: []
}
},{
“name”: “owner”,
“parent”: “owner”,
“required_auth”: {
“threshold”: 1,
“keys”: [{
“key”: “EOS4toFS3YXEQCkuuw1aqDLrtHim86Gz9u3hBdcBw5KNPZcursVHq”,
“weight”: 1
}
],
“accounts”: []
}
}
]
}
创建或修改权限
要修改帐户的权限，您必须拥有该帐户的权限和您正在修改的权限。设置帐户权限命令可能会更改，因此它关联的类没有完整记录。
$ cleos set account permission test active ‘{“threshold” : 1, “keys” : [{“permission”:{“key”:“EOS8X7Mp7apQWtL6T2sfSZzBcQNUqZB7tARFEm9gA9Tn9nbMdsvBB”,“permission”:“active”},“weight”:1}], “accounts” : [{“permission”:{“actor”:“acc2”,“permission”:“active”},“weight”:50}]}’ owner
第二个示例修改相同的帐户权限，但删除上一个示例中的密钥集，并将@test帐户的活动权限授予另一个帐户。
$ cleos set account permission test active ‘{“threshold” : 1, “keys” : [], “accounts” : [{“permission”:{“actor”:“sandwich”,“permission”:“active”},“weight”:1},{“permission”:{“actor”:“acc1”,“permission”:“active”},“weight”:50}]}’ owner
第三个示例演示如何设置multisig的权限
$ cleos set account permission test active ‘{“threshold” : 100, “keys” : [{“permission”:{“key”:“EOS8X7Mp7apQWtL6T2sfSZzBcQNUqZB7tARFEm9gA9Tn9nbMdsvBB”,“permission”:“active”},“weight”:25}], “accounts” : [{“permission”:{“actor”:"@sandwich",“permission”:“active”},“weight”:75}]}’ owner
此命令中使用的JSON对象实际上由两种不同类型的对象组成
权限JSON对象…
{
“threshold” : 100, /An integer that defines cumulative signature weight required for authorization/
“keys” : [], /An array made up of individual permissions defined with an EOS PUBLIC KEY/
“accounts” : [] /An array made up of individual permissions defined with an EOS ACCOUNT/
}
…其中包括一个或多个权限对象
/Set Permission with Key/
{
“permission” : {
“key” : “EOS8X7Mp7apQWtL6T2sfSZzBcQNUqZB7tARFEm9gA9Tn9nbMdsvBB”,
“permission” : “active”
},
weight : 25 /Set the weight of a signature from this permission/
}
/Set Permission with Account/
{
“permission” : {
“actor” : “sandwich”,
“permission” : “active”
},
weight : 75 /Set the weight of a signature from this permission/
}
部署合约
要将合约上传到区块链，您必须先持有一个帐户和一个持有该帐户的钱包。其次，你需要你的合同文件（.wast）和它的abi（.abi）。然后你可以继续设置代码。
$ cleos set contract currency …/…/…/contracts/currency/currency.wast …/…/…/contracts/currency/currency.abi

查询ABI
我们可以在区块链中查询合同的.abi，我们可以在其中查看可用操作列表及其各自的消息结构
$ cleos get code -a currency.abi currency
code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975
saving abi to currency.abi
$ cat currency.abi
{
“types”: [{
“newTypeName”: “AccountName”,
“type”: “Name”
}
],
“structs”: [{
“name”: “transfer”,
“base”: “”,
“fields”: {
“from”: “AccountName”,
“to”: “AccountName”,
“amount”: “UInt64”
}
},{
“name”: “account”,
“base”: “”,
“fields”: {
“account”: “Name”,
“balance”: “UInt64”
}
}
],
“actions”: [{
“action”: “transfer”,
“type”: “transfer”
}
],
“tables”: [{
“table”: “account”,
“indextype”: “i64”,
“keynames”: [
“account”
],
“keytype”: [],
“type”: “account”
}
]
}
推送操作
根据合同ABI，消息应该是合同。
例如，货币合约的ABI被构造如下。
$ cleos get code -a currency.abi currency
code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975
saving abi to currency.abi
$ cat currency.abi
{
“types”: [{
“newTypeName”: “AccountName”,
“type”: “Name”
}
],
“structs”: [{
“name”: “transfer”,
“base”: “”,
“fields”: {
“from”: “AccountName”,
“to”: “AccountName”,
“amount”: “UInt64”
}
},{
“name”: “account”,
“base”: “”,
“fields”: {
“account”: “Name”,
“balance”: “UInt64”
}
}
],
“actions”: [{
“action”: “transfer”,
“type”: “transfer”
}
],
“tables”: [{
“table”: “account”,
“indextype”: “i64”,
“keynames”: [
“account”
],
“keytype”: [],
“type”: “account”
}
]
}
从上面的abi中，我们可以看到货币合约接受一个叫做transfer的操作，它接受带有from，to和amount字段的消息。
$ ./cleos push message currency transfer ‘{“from”:“currency”,“to”:“tester”,“amount”:50}’ -S currency -S tester -p currency@active

}

“sync_transactions”: [],
“async_transactions”: []
}
]
}
}
查询合约
根据合约中定义的表结构，您可以查询合同中的数据。
例如，currency合约ABI包含账户表。
$ cleos get code -a currency.abi currency
code hash: 9b9db1a7940503a88535517049e64467a6e8f4e9e03af15e9968ec89dd794975
saving abi to currency.abi
$ cat currency.abi
{
…
“tables”: [{
“table”: “account”,
“indextype”: “i64”,
“keynames”: [
“account”
],
“keytype”: [],
“type”: “account”
}
]
}
您可以查询指定必要字段的表格。
$ cleos get table inita currency account
{
“rows”: [{
“account”: “account”,
“balance”: 50
}
],
“more”: true
}
跳过签名
如果您的本地运行nodeos，作为开发人员在不处理密钥的情况下测试功能的简便方法，则可以运行nodeos以便不需要Transaction签名。
$ nodeos --skip-transaction-signatures
然后对于任何需要签名的操作，请使用-s选项
$ cleos ${command} ${subcommand} -s ${param}
使用独立的钱包应用
您可以使用可在program/keosd中找到的单独的钱包应用程序，而不是使用内置于nodeos的钱包功能。默认情况下，节点使用端口8888，因此请为钱包应用选择另一个端口。
$ keosd --http-server-endpoint 127.0.0.1:8887
然后，对于任何需要签名的操作，请使用-wallet-host和-wallet-port选项.
$ cleos —-wallet-url 127.0.0.1:8887 ${command} ${subcommand} ${param}
错误示例
status_code == 200: Error

test: assertion failed: integer underflow subtracting token balance
{“s”:“integer underflow subtracting token balance”,“ptr”:176}
