在 golang 中循环 struts 的数组

Question

我的术语可能不适用，所以我使用了一些 python 个术语。

在 golang 中尝试做的是迭代具有这样存储值的支柱（这是我从 api 得到的）

[{STOREA 0 0 0} {STOREB 0 0 0} {STOREC 0 0 0} {STORED 0 0 0}]

在 python 中，我将其称为听写列表。

当我将鼠标悬停在可视代码中的值上时，它指出：

field itemData []struct{Code string "json:"Code""; Items int "json:"Items""; Price float64 "json:"Price""; Qty int "json:"Qty""}

package main

// I think this is the right way to interpret what visual code stated
type itemData struct {
    Code string  `json:"Code"`
    Items int     `json:"Items"`
    Price   float64 `json:"Price"`
    Qty int     `json:"Qty"`
    }

//I'm trying to simulate the api response by storing it in a varible like this but I think the [] are an issue and im doing it incorrectly
var storeData = itemData[{STOREA 0 0 0} {STOREB0 0 0} {STOREC 0 0 0} {STORED0 0 0}] // I think the [ ] brackets are causing an issue

//The idea is I can iterate over it like this:
for k,v := range storeData {
    fmt.Printf(k,v)
    }

Answer 1

推荐给A Tour of Go - Slice

然后试试这个：

    var storeData = []itemData{{"STOREA", 0, 0, 0}, {"STOREB", 0, 0, 0}, {"STOREC", 0, 0, 0}, {"STORED", 0, 0, 0}}
    for k, v := range storeData {
        fmt.Println(k, v)
    }

Answer 2

您得到的是 slice 个 itemData (struct)。使用切片文字用值初始化切片非常简单。它看起来像这样：

    storeData := []itemData{
        {
            Code:  "STOREA",
            Items: 0,
            Price: 0,
            Qty:   0,
        },
        {
            Code:  "STOREB0",
            Items: 0,
            Price: 0,
        },
        {
            Code:  "STOREC",
            Items: 0,
            Price: 0,
            Qty:   0,
        },
        {
            Code:  "STORED0",
            Items: 0,
            Price: 0,
        },
    }
    for i, v := range storeData {
        fmt.Printf("index: %d, value: %v\n", i, v)
    }
