读取csv文件时跳过第一行
例如，
package mainimport ( "bufio" "encoding/csv" "fmt" "io" "os")func readSample(rs io.ReadSeeker) ([][]string, error) { // Skip first row (line) row1, err := bufio.NewReader(rs).ReadSlice('n') if err != nil { return nil, err } _, err = rs.Seek(int64(len(row1)), io.SeekStart) if err != nil { return nil, err } // Read remaining rows r := csv.NewReader(rs) rows, err := r.ReadAll() if err != nil { return nil, err } return rows, nil}func main() { f, err := os.Open("sample.csv") if err != nil { panic(err) } defer f.Close() rows, err := readSample(f) if err != nil { panic(err) } fmt.Println(rows)}输出：
