utils: use strings.Split instead of strings.IndexByte (#1400)
And I test them benchmark:
code:
```go
package stringsbench
import "strings"
func index(part string) string {
if index := strings.IndexByte(part, ';'); index >= 0 {
if part := strings.TrimSpace(strings.Split(part, ";")[0]); part != "" {
return part[0:index]
}
}
return ""
}
func split(part string) string {
return strings.Split(part, ";")[0]
}
```
```go
package stringsbench
import (
"testing"
)
func BenchmarkIndex(b *testing.B) {
b.RunParallel(func(pb *testing.PB) {
for pb.Next() {
index("text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
}
})
}
func BenchmarkSplit(b *testing.B) {
b.RunParallel(func(pb *testing.PB) {
for pb.Next() {
split("text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
}
})
}
```
And the result:
```shell
➜ strings go test --bench=.
goos: darwin
goarch: amd64
BenchmarkIndex-8 30000000 46.1 ns/op
BenchmarkSplit-8 50000000 35.9 ns/op
