查看權(quán)限

有人說查看權(quán)限非常簡單，不就是看看用戶信息嘛！
其實(shí)不然，EOS用戶的權(quán)限是與key相關(guān)聯(lián)的，所以確定你有沒有全縣的其實(shí)是要看你有沒有這些公匙對應(yīng)的私匙：

查看自己帳戶的詳細(xì)信息：

cleos get account lome

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS8FbfG31mJELxUS4Jj9Xv3tsNRzFMg2uP2h9b5hCkvHomsatVYw","weight": 1}],"accounts": []}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": []}}] }

更改授權(quán)

更改權(quán)限的key

初始化的帳戶是有兩種權(quán)限的，這一步我們來給帳戶加一個權(quán)限(群組)。
1.這里我就拿我在測試的公網(wǎng)上的一個帳戶，
初始化的帳戶是這樣的：

下面講解一下命令：

cleos set account permission ${account_name} ${permission} ${JSON} ${permission}

cleos set account permission lome active '{"threshold": 1, "keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg", "weight": 1}], "accounts": []}' owner

更改以后的賬號如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1}],"accounts": []}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": []}}] }

參數(shù)說明：

threshold權(quán)限閥值，權(quán)限等于閥值才能獲取該權(quán)限，否則授權(quán)失敗

keys 是該權(quán)限已授權(quán)的密匙 ： keys中的key為授權(quán)的密匙對的公匙，weight 為授權(quán)密匙對的權(quán)重 ps： 若閥值是2，權(quán)重是1，是不能夠完成授權(quán)的，操作將失敗.

accounts 是該權(quán)限已授權(quán)的帳戶： permission是被授權(quán)用戶的權(quán)限這里指的就是lome的active權(quán)限，weight指的也是權(quán)重。

ps：重要：授權(quán)用戶權(quán)限其實(shí)跟授權(quán)key是一個道理，其實(shí)授權(quán)帳戶權(quán)限，實(shí)質(zhì)上就是授權(quán)該權(quán)限的密匙對權(quán)限。

最后owner是權(quán)限，只有owner權(quán)限才能改變用戶的權(quán)限

值得一提的是：EOS3.0對權(quán)限及權(quán)重做了校驗(yàn)。如果我的命令是這樣的：

cleos set account permission lome active '{"threshold":2,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1}],"accounts":[]}' owner

該操作將會失敗，因?yàn)檫@個權(quán)限根本就達(dá)不到伐值，2.0在這里是沒有校驗(yàn)的，錯誤提示如下:

Error 3040000: message validation exception Error Details: Invalid authority: {"threshold":2,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1}],"accounts":[]}

增加權(quán)限的授權(quán)賬戶

cleos set account permission lome active '{"threshold":2,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1}],"accounts":[{"permission":{"actor":"eosio","permission":"active"},"weight":1}]}' owner

這里更改的是lome賬戶權(quán)限的accounts權(quán)限,下面看一下更改完成后我的賬戶：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 2,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1}],"accounts": [{"permission": {"actor": "eosio","permission": "active"},"weight": 1}]}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": []}}] }

在這里我的權(quán)重伐值為2，key的權(quán)重為1，eosio@active的權(quán)重為1.那么要使用lome@active權(quán)限就需要key和eosio@active所對應(yīng)的key的權(quán)限。

增加多個授權(quán)key

增加授權(quán)的命令如下：

cleos set account permission lome active '{"threshold":1,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1},{"key":"EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight":1}],"accounts":[]}' owner

結(jié)果如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1},{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": []}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5hepJxGjP3X93wVmXZeBSNavGWeJvwWtev5ak8oARqwrXjehXd","weight": 1}],"accounts": []}}] }

增加權(quán)限多個授權(quán)賬戶

增加授權(quán)的命令如下：

cleos set account permission lome active '{"threshold":1,"keys":[],"accounts":[{"permission":{"actor":"test","permission":"active"},"weight":1},{"permission":{"actor":"eosio","permission":"active"},"weight":1}]}' owner

結(jié)果如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [],"accounts": [{"permission": {"actor": "test","permission": "active"},"weight": 1},{"permission": {"actor": "eosio","permission": "active"},"weight": 1}]}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5hepJxGjP3X93wVmXZeBSNavGWeJvwWtev5ak8oARqwrXjehXd","weight": 1}],"accounts": []}}] }

增加多個授權(quán)key && 增加權(quán)限多個授權(quán)賬戶

增加授權(quán)的命令如下：

cleos set account permission lome active '{"threshold":1,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1},{"key":"EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight":1}],"accounts":[{"permission":{"actor":"test","permission":"active"},"weight":1},{"permission":{"actor":"eosio","permission":"active"},"weight":1}]}' owner

結(jié)果如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1},{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": [{"permission": {"actor": "test","permission": "active"},"weight": 1},{"permission": {"actor": "eosio","permission": "active"},"weight": 1}]}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5hepJxGjP3X93wVmXZeBSNavGWeJvwWtev5ak8oARqwrXjehXd","weight": 1}],"accounts": []}}] }

增加權(quán)限

代碼如下：

cleos set account permission lome test '{"threshold":1,"keys":[{"key":"EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight":1}],"accounts":[]}' active

結(jié)果如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1},{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": [{"permission": {"actor": "test","permission": "active"},"weight": 1},{"permission": {"actor": "eosio","permission": "active"},"weight": 1}]}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5hepJxGjP3X93wVmXZeBSNavGWeJvwWtev5ak8oARqwrXjehXd","weight": 1}],"accounts": []}},{"perm_name": "test","parent": "active","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1}],"accounts": []}}] }

刪除權(quán)限

終于來到了最后一節(jié)，恭喜你！
有人會說這個權(quán)限或者群組沒用了怎么辦？這節(jié)我就來教你，我們來刪除它：
執(zhí)行代碼如下

cleos set account permission lome test 'NULL' active

命令就不再多贅述什么意思。這個命令中只有NULL前面沒見過，這里是用來專門刪除權(quán)限或者群組用的。執(zhí)行結(jié)果如下：

{"account_name": "lome","permissions": [{"perm_name": "active","parent": "owner","required_auth": {"threshold": 1,"keys": [{"key": "EOS6ePVMSdSkGn4wDMqcCSTSN3GnRgEPxDPEioQQXUkfYxT8jrudg","weight": 1},{"key": "EOS5wMFMPiD6qbKSZQpJFdEpzvY2yC2o6XLsg97gPPrYHbW4KovjV","weight": 1}],"accounts": [{"permission": {"actor": "test","permission": "active"},"weight": 1},{"permission": {"actor": "eosio","permission": "active"},"weight": 1}]}},{"perm_name": "owner","parent": "","required_auth": {"threshold": 1,"keys": [{"key": "EOS5hepJxGjP3X93wVmXZeBSNavGWeJvwWtev5ak8oARqwrXjehXd","weight": 1}],"accounts": []}}] }
