## 3. 字符串查找
```go
strings.Contains("widuu", "wi") // 查找某个字符是否在这个字符串中存在, return true
strings.Contains("wi", "widuu") // 查找某个字符是否在这个字符串中存在, return false
trings.ContainsAny("widuu", "w&d") // 查询字符串中是否包含多个字符, return true
strings.Contains("widuu", "id") // 查找某个字符是否在这个字符串中存在, return true
strings.Contains("id", "widuu") // 查找某个字符是否在这个字符串中存在, return false
strings.Contains("widuu", "i&d") // 查找某个字符是否在这个字符串中存在, return false
strings.ContainsAny("widuu", "i&d") // 查询字符串中是否包含多个字符, return true
strings.Count("widuu", "uu") // 在一段字符串中有多少匹配到的字符, return 1
strings.Count("widuu", "u") // 在一段字符串中有多少匹配到的字符, return 2
strings.Index("widuu", "i") // 查找字符串, 然后返回当前的位置, return 1

## 4. 剔除字符
```go
strings.TrimSpace(" He llo ") // 剔除前后空格，return "He llo"
strings.Trim("+He+llo++", "+") // 剔除前后指定字符，return "He+llo"
strings.TrimLeft("+-+-He+-llo+-+-", "+-") // 剔除左侧任意匹配字符，return "He+-llo+-+-"
strings.TrimRight("+-+-He+-llo+-+-", "+-") // 剔除右侧任意匹配字符，return "+-+-He+-llo"
strings.TrimPrefix("+-+-He+-llo+-+-", "+-") // 仅剔除一组完全匹配的前导符，return "+-He+-llo+-+-"
strings.TrimSuffix("+-+-He+-llo+-+-", "+") // 仅剔除一组完全匹配的后导符，return "+-+-He+-llo+-"
