如何在golang切片中搜索元素 |

icz*_*cza 84

for

for _, v := range myconfig {
    if v.Key == "key1" {
        // Found!
    }
}

struct

range

for i := range myconfig {
    if myconfig[i].Key == "key1" {
        // Found!
    }
}

笔记:

keybreak

for i := range myconfig {
    if myconfig[i].Key == "key1" {
        // Found!
        break
    }
}

map

// Build a config map:
confMap := map[string]string{}
for _, v := range myconfig {
    confMap[v.Key] = v.Value
}

// And then to find values by key:
if v, ok := confMap["key1"]; ok {
    // Found
}
