Hello , 我是09

此篇内容为我2018~2020年在【库神】工作时，对部分重要知识做的学习总结

随着比特币冲破10万美金，行业又再次兴起，希望相关从业者可以学习到你需要的内容

投票前，需要先将自己注册到投票系统

注册配置参数：

(1.) action = regproxy

(2.) code = eosio

(3.) proxy = 账户名称

(4.) isproxy = @"0"

 

注册返回的重要参数为binargs，返回数据大概为

{
        message = "ok",
        data =     {
         binargs = "10c420850c117ce750c810410c527ce7102700000000000004454f53000000000474657374",
        },
        code = 0,
}

 

获取blockChain （最新区块信息）

不需要任何注册参数

返回的内容大致如下

{
            message = "ok",
              data = {
                     head_block_id = "00580b4f39fafd062154534c6c743a0e8b48b5f992775af2339d245153254dbe",
                     last_irreversible_block_num = 5769729,
                     head_block_producer = "starteosiobp",
                     virtual_block_net_limit = 1048576000,
                     server_version = "db031363",
                     head_block_time = "2018-07-14T02:52:04.500",
                     block_cpu_limit = 169814,
                     block_net_limit = 1038080,
                     last_irreversible_block_id = "00580a01aa1aca06e95da40516f842e31653e10fa0666935d853ae767ee04412",
                     virtual_block_cpu_limit = 200000000,
                     chain_id = "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
                     head_block_num = 5770063,
              },
              code = 0,
}

其中最主要的信息为

(1.) chain_id                  用于配置chain_Id
(2.) head_block_time 用于weakSelf.expiration = [[[NSDate dateFromString: model.head_block_time] dateByAddingTimeInterval: 30] formatterToISO8601];
(3.) head_block_num 用于ref_block_num
(4.) head_block_id 在Demo中需要通过JS进行一些列计算的转换之后当做ref_block_prefix参数使用

 

发送交易

发送交易的参数只有两个

packed_trx       //交易数据
signatureStr     //签名

配置交易数据，大致信息如下

(1. )  ref_block_prefix             区加快信息中的head_block_id通过一些列运算后得到
(2. )  ref_block_num                区加快信息中的head_block_num直接使用
(3. )  expiration                   区块信息中的head_block_time字段，经过处理后得到
(4. )  context_free_data            写死空数组 @[]
(5. )  signatures                   写死空数组 @[]
(6. )  context_free_actions         写死空数组 @[]
(7. )  delay_sec                    写死0  (NSNumber类型)
(8. )  max_kcpu_usage               写死0  (NSNumber类型)
(9. )  max_net_usage_words          写死0  (NSNumber类型)
(10. ) account                      帮我创建的人的账户名      eosio
(11. ) name                         传入action
(12. ) data                         传入binargs
(13. ) actor                        账户名
(14. ) permission                   写死active
