Safe Mode 命令

Safe Mode 命令用于在区块链出现共识分歧的时候保护矿工，停止生成区块模板和接受交易。

可以使用mvc-cli help command来查看具体命令的使用方法。JsonRpc调用方法在示例中。

命令列表

命令列表如下（从文档右侧边框选取对应的命令进行查看）：

== Safemode ==
getsafemodeinfo

reconsidersafemodeforblock "blockhash"

getsafemodeinfo

获取当前节点的Safe Mode状态，以及对应的区块信息。

getsafemodeinfo

Returns safe mode status.

Examples:
> mvc-cli getsafemodeinfo
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getsafemodeinfo", "params": [] }' -H 'content-type: text/plain;' http://127.0.0.1:9882/

ignoresafemodeforblock

忽略指定区块的Safe Mode状态，继续生成区块模板和接受交易。

参数：

• blockhash (string, required) 要忽略的区块哈希值。

ignoresafemodeforblock "blockhash"

Specified block, and all its descendants, will be ignored for safe mode activation.

Arguments:
1. "blockhash"   (string, required) the hash of the block which we want to ignore.

Result:

Examples:
> mvc-cli ignoresafemodeforblock "blockhash"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "ignoresafemodeforblock", "params": ["blockhash"] }' -H 'content-type: text/plain;' http://127.0.0.1:9882/

reconsidersafemodeforblock

重新考虑指定区块的Safe Mode状态，停止生成区块模板和接受交易。

参数：

• blockhash (string, required) 要重新考虑的区块哈希值。

reconsidersafemodeforblock "blockhash"

Specified block, and all its ancestors, will be considered for safe mode activation.

Arguments:
1. "blockhash"   (string, required) the hash of the block for which we want

Result:

Examples:
> mvc-cli reconsidersafemodeforblock "blockhash"
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "reconsidersafemodeforblock", "params": ["blockhash"] }' -H 'content-type: text/plain;' http://127.0.0.1:9882/
