这篇“EOS区块链怎么开发使用”文章的知识点大部分人都不太理解,所以小编给大家总结了以下内容,内容详细,步骤清晰,具有一定的借鉴价值,希望大家阅读完这篇文章能有所收获,下面我们一起来看看这篇“EOS区块链怎么开发使用”文章吧。
EOSIO附带了许多程序。你将使用的主要部分以及此处涉及的部分是:
nodeos(node + eos = nodeos) ,可以使用插件配置以运行节点的核心EOSIO节点守护程序。示例用法是块生产,专用API端点和本地开发。
cleos(cli + eos = cleos) ,命令行界面,用于与区块链交互并管理钱包。
keosd(key + eos = keosd) ,将EOSIO密钥安全存储在钱包中的组件。
eosio-cpp(eosio.cdt的一部分) ,它将C ++代码编译为WASM并可以生成ABI(CDT是合约开发工具链)。
这些组件之间的基本关系如下图所示。
nodeos:1.5.0
cleos:1.5.0
keosd:1.5.0
eosio.cdt:1.4.1
eosio.contracts:1.4.0
有几种方法可以做到:
1.使用Docker,快速简便。
2.使用二进制文件,它也行。
You create 2 containers. One for 'nodeos' and another for 'keosd' #Pull latest docker image of EOS docker pull eosio/eos-dev #Create local network docker network create eosdev #Start nodeos(Core Daemon) docker run --name nodeos -d -p 8888:8888 --network eosdev -v /tmp/eosio/work:/work \ -v /tmp/eosio/data:/mnt/dev/data -v /tmp/eosio/config:/mnt/dev/config eosio/eos-dev \ /bin/bash -c "nodeos -e -p eosio --plugin eosio::producer_plugin \ --plugin eosio::history_plugin --plugin eosio::chain_api_plugin \ --plugin eosio::history_api_plugin --plugin eosio::http_plugin \ -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:8888 \ --access-control-allow-origin=* --contracts-console --http-validate-host=false" ###### NOTES about above Command - Creating a docker container running 'nodeos' daemon - Exposing port 8888 so that you can access the 'nodeos' using RPC and HTTP - Mounting few directories on your local machine so that you don't have to login into container - Few plugins which will allow this node to become a producer, expose rpc api over http, exposing command line interface to run 'nodeos' commands #Run keosd(Wallet and Keystore) docker run -d --name keosd --network=eosdev -i eosio/eos-dev /bin/bash \ -c "keosd --http-server-address=0.0.0.0:9876" #Check installation docker logs --tail 10 nodeos and you will see something like: info 2018-12-04T15:01:22.003 thread-0 producer_plugin.cpp:1494 produce_block ] Produced block 00005ce7fabcbcf8... #23783 @ 2018-12-04T15:01:22.000 signed by eosio [trxs: 0, lib: 23782, confirmed: 0] info 2018-12-04T15:01:22.507 thread-0 producer_plugin.cpp:1494 produce_block ] Produced block 00005ce84867bcbf... #23784 @ 2018-12-04T15:01:22.500 signed by eosio [trxs: 0, lib: 23783, confirmed: 0] info 2018-12-04T15:01:23.005 thread-0 producer_plugin.cpp:1494 produce_block ] Produced block 00005ce936ca4869... #23785 @ 2018-12-04T15:01:23.000 signed by eosio [trxs: 0, lib: 23784, confirmed: 0] i #Check Wallets (Open bash for keosd) docker exec -it keosd bash and once in the container, on bash, execute this: cleos --wallet-url http://127.0.0.1:9876 wallet list keys Should show empty wallets: Wallets: [] #Check 'nodeos' end points - run this out side containers curl http://localhost:8888/v1/chain/get_info { "server_version":"549c96cd", "chain_id":"cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f", "head_block_num":24182, "last_irreversible_block_num":24181, "last_irreversible_block_id":"00005e751a1e31b15acd25ffc8725cb2c67926647edb89e726e386716afdef5d", "head_block_id":"00005e76fd035dbf694d2a575bb1849f436428b466fd95323e43619b73bf7b9d", "head_block_time":"2018-12-04T15:04:41.500", "head_block_producer":"eosio", "virtual_block_cpu_limit":200000000, "virtual_block_net_limit":1048576000, "block_cpu_limit":199900, "block_net_limit":1048576, "server_version_string":"v1.5.0-rc2" } #Alias cleos so that you can access it by simply 'cleos' docker network inspect eosdev check for keosd IP address in the response of above command and execute the following: alias cleos='docker exec -it nodeos /opt/eosio/bin/cleos --url http://127.0.0.1:8888 --wallet-url http://172.18.0.3:9876'

上述步骤之一将帮助你设置和运行本地节点。
现在你准备好在区块链上做一些事情。在EOS中,你必须拥有一个帐户才能执行任何操作,例如创建token,发送token,接收token,编写交易等。此节点将有一个名为eosio
的系统用户,因此你可以使用此用户来玩eos区块链。
因此,在本节中,我们将在本地节点上执行以下操作:
创建一个新钱包。
创建新密钥(私人+公共)。
将这些钥匙导入钱包。
建立新帐户。
让我们运行一些命令并观察你所看到的。只需阅读所有命令的注释,即可了解它们的作用。
#List existing wallets. Wallet stores keys cleos wallet list #List wallet keys if any cleos wallet list key #you should see all empty response #create wallet now cleos wallet create Creating wallet: default "PW5JYR5u7WTk6RaJARE41qb3Wy6BJtcKCjpDAyjR2uV3CWF8nDFe7" this will create wallet with name 'default'. Keep note of password it returns. #Create new keys cleos create key --to-console Private key: 5JseP8pEsJfAEWix5U6ow77TrKu2uuBhjfobyzgYyCYAtnxnCk8 Public key: EOS4tmc8ufENZNkFQaj8ZfV9UfeRLnyaCecybSgPS1U8671BNdSxD #Import the private keys in wallet cleos wallet import -n quant --private-key 5JseP8pEsJfAEWix5U6ow77TrKu2uuBhjfobyzgYyCYAtnxnCk8 #### MOST IMPORTANT STEP #### Import genesis 'eosio' account keys in the wallet so that eosio account is available for creating new accounts. Private key of eosio: 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
在这个阶段,你已准备好带有eosio
(创世纪帐户)的钱包和导入的新密钥。所以我们现在准备好做更多的操作了。
我们将在下一节中执行以下操作:
部署token合约,以便区块链准备好创建新的token。
创建新token。
将新token分配给创世帐户(eosio)。
在用户之间转移token。
检查余额等。

It simply means above steps are successful. #Check balance now of eosio account cleos get currency balance eosio.token eosio you would see: 1000000000.0000 EOS
你去了,现在你已经创建了token,eosio
帐户有很多EOS token,他现在可以轻松地将资金发送到其他帐户。
#Create a new account cleos create account eosio user1 <public_key_of_user1> <public_key_of_user1> #Check if account is created. You should have json response cleos get account user1 #Send money to user1 account cleos transfer eosio user1 "1000.00 EOS" #Check the balance of user1 cleos get currency balance eosio.token vijay1
仅此而已!
