How to Decode map golang
问题
你运行代码后得到了以下地图：
map[from:0 key:<nil> price:Desc title:stack]
你想要获取from、price和title的值。
请帮助我。

一旦你构建好了地图，你可以通过提供键来访问地图的值。语法如下：
value := myMap[myKey]
键的类型可以是任何可以通过比较运算符（>=，==，<=等）进行评估的类型。根据你的示例，看起来你正在使用字符串作为键。
以下是一个示例：
m := map[string]interface{}{
"from": 0,
"key": nil,
"price": "Desc",
"title": "task",
}
// 获取 price 的值
price := m["price"]
fmt.Println(price)
// 获取 title
title := m["title"]
fmt.Println(title)
// 遍历地图的所有键值对
for key, value := range m {
fmt.Println(key, ":", value)
}
英文:
Once you have your map constructed, you can access a value of the map by providing the key. The syntax is:
value := myMap[myKey]
The key's type can be any type that can be evaluated by a comparison operator ( >=, ==, <=, etc...). For your example it looks like you are using strings for keys.
Here's an example:
m := map[string]interface{}{
"from": 0,
"key": nil,
"price": "Desc",
"title": "task",
}
// Get the value of price
price := m["price"]
fmt.Println(price)
// Get the title
title := m["title"]
fmt.Println(title)
// Loop through all of the map's key-value pairs
for key, value := range m {
fmt.Println(key, ":", value)
}
