上次编译了facebook的区块链，好几天没用了，今天就接下来尝试运行基本操作
先在编译的基础下运行：
编译运行facebook区块链libra(1)--by Skyh
1. 运行测试网
./scripts/cli/start_cli_testnet.sh
然后出现： Running target/debug/client --host ac.testnet.libra.org --port 80 -s ./scripts/cli/trusted_peers.config.toml
Not able to connect to validator at ac.testnet.libra.org:80, error RpcFailure(RpcStatus { status: DeadlineExceeded, details: Some("Deadline Exceeded") })
image.png
怎么会有时间错误，查看issue
https://github.com/libra/libra/issues/38
image.png
需要修改libra/client/src/grpc_client.rs 增大
image.png
重新调用即可打开
./scripts/cli/start_cli_testnet.sh
image.png
显示可以运行的基本命令
Use the following commands:
account | a
Account operations
query | q
Query operations
transfer | transferb | t | tb
<sender_account_address>|<sender_account_ref_id> <receiver_account_address>|<receiver_account_ref_id> <number_of_coins> [gas_unit_price_in_micro_libras (default=0)] [max_gas_amount_in_micro_libras (default 10000)] Suffix 'b' is for blocking.
Transfer coins (in libra) from account to another.
help | h
Prints this help
quit | q!
Exit this client
2. 运行命令
查看account子命令（文中命令缩写）
libra% a
usage: a <arg>
Use the following args for this command:
create | c
Create an account. Returns reference ID to use in other operations
list | la
Print all accounts that were created or loaded
recover | r <file_path>
Recover Libra wallet from the file path
write | w <file_path>
Save Libra wallet mnemonic recovery seed to disk
mint | mintb | m | mb <receiver_account_ref_id>|<receiver_account_address> <number_of_coins>
Mint coins to the account. Suffix 'b' is for blocking
自己本地创建2个账户
libra% a c
>> Creating/retrieving next account from wallet
Created/retrieved account #0 address 4c52e97c3219c731be98f3f228a05324afc46200462c33ceea4f0964b7baf68c
libra% a c
>> Creating/retrieving next account from wallet
Created/retrieved account #1 address 9e6ae041beb3048007f285f70f56e16ec252a4545573ca36e60e9ee52c81bf56
列出所有账户
libra% a la
User account index: 0, address: 4c52e97c3219c731be98f3f228a05324afc46200462c33ceea4f0964b7baf68c, sequence number: 0, status: Local
User account index: 1, address: 9e6ae041beb3048007f285f70f56e16ec252a4545573ca36e60e9ee52c81bf56, sequence number: 0, status: Local
image.png
吐槽： libra的account创建只能从索引0开始递增，账号只有索引码不够形象，如果账号多起来比较难分辨，只能通过数据库一一对应， 不像EOS那样可以直接字符账号
3. 创建libra并转帐
创建110个libra并添加到0账户， 和52个到2账户
a m 0 110
a m 1 52
返回只有 Mint request submitted并没有详细信息
image.png
下面查看余额，先看看query有什么命令：
image.png
查看0和1的余额（直接代码不图片了）
libra% q b 0
Balance is: 110
libra% q b 1
Balance is: 52
进行转账，先看看转账有什么操作
image.png
libra% t 0 1 10
>> Transferring
Transaction submitted to validator
To query for transaction status, run: query txn_acc_seq 0 0 <fetch_events=true|false>
注意：这次转账是非阻塞的，发起即刻输出结果，但不确定转账是否成功到账
确认转账成功需要调用
query txn_acc_seq 0 0 true
可看到记录上链的信息（失败信息还没模拟）
image.png
** 查看某账号交易数**，这时可以看到0 和1 的交易数， 还有余额
libra% q s 0
>> Getting current sequence number
Sequence number is: 1
libra% q s 1
>> Getting current sequence number
Sequence number is: 0
libra% q b 0
Balance is: 100
libra% q b 1
Balance is: 62
libra%
1 已经收到了 0 号的10个libra
注意： 发现对0账号 交易数有1， 而1账号收到账并没有显示交易数，这跟其他链也不一样， 可能通过其他方法查
如果需要确认状态转账成功， 可以用阻塞转账命令，本地目测也是1s左右完成吧
libra% tb 0 1 10
>> Transferring
[waiting *
Transaction completed, found sequence number 2
Finished transaction!
To query for transaction status, run: query txn_acc_seq 0 1 <fetch_events=true|false>
4 附加：一些实用命令：
查询用户状态
libra% query account_state 0
>> Getting latest account state
Latest account state is:
Account: 4c52e97c3219c731be98f3f228a05324afc46200462c33ceea4f0964b7baf68c

received_events_count: 0,
},
)
},
)
Blockchain Version: 150463
另外，找到一个可以1账号查收到账的命令， 就是
#查0转账index 0 开始
query event 0 sent 0 true 10
#查1收账index 0 开始
query event 1 received 0 true 10
下面是收账返回信息，也能看到些内部结构，好像还有gas：
libra% query event 1 received 0 true 10
>> Getting events by account and event type.
