如何在卡尔达诺节点中找到当前的 a0 参数

问题描述

他们有没有办法从节点获取 a0 参数的当前值？ 在配置文件中找不到参数。这些在节点启动时不会作为参数传递。

解决方法

您可以使用 library(tidyverse) mytibble <- tribble( ~shopid,~oldvarname,~postcode1,~postcode2,~postcode3,"A","postcode","A110","B220","Z112","itemssold","10","20","30","B","A214","C112",NA,"15","C","A221","4",NA) df1 <- mytibble %>% filter(oldvarname=="postcode") %>% pivot_longer( cols = starts_with("postcode"),names_to = "names",values_to = "postcode" ) %>% select(-oldvarname,-names) %>% drop_na() df2 <- mytibble %>% filter(oldvarname=="itemssold") %>% pivot_longer( cols = starts_with("postcode"),values_to = "itemssold" ) %>% select(-oldvarname,-names) %>% drop_na() df1$itemssold <- df2$itemssold 获取协议参数：

curCart =[{sku:1,name:product1,qty:1 price:5},{sku:1,{sku:2,name:product2,qty:1 price:10}]

[...new Map(curCart.map((item) => [item.sku,item])
            ).values(),] // returns [{sku:1,qty:1 price:10}]
