我的術語可能不適用，所以我使用了一些 python 術語。在 golang 中嘗試做的是迭代一個具有這樣存儲值的支柱（這是我從 api 返回的）[{STOREA 0 0 0} {STOREB 0 0 0} {STOREC 0 0 0} {STORED 0 0 0}]在 python 中，我將其稱為字典列表。當我將鼠標懸停在可視代碼中的值上時，它指出：field itemData []struct{代碼字符串 "json:"Code""; 項目 int "json:"項目""; 價格 float64 "json:"價格""; 數量 int "json:"數量""}package main// I think this is the right way to interpret what visual code statedtype 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 incorrectlyvar 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) }

推薦給Go 之旅 - Slice
然后試試這個：
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)
}

你所擁有的slice是itemData( struct)。使用切片文字用值初始化切片非常簡單。它看起來像這樣：
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)
}
