parse error on line 1, column 4: bare “ in non-quoted-field

golang报错：

parse error on line 1, column 4: bare " in non-quoted-field

可能的原因是csv是windowns 导出的，编码方式是UTF-8 BOM 方式。
可以通过跳过BOM解决：

import ("os""log"
)func main() {fd, err := os.Open("filename")if err != nil {log.Fatal(err)}defer closeOrDie(fd)bom := [3]byte_, err = io.ReadFull(fd, bom[:])if err != nil {log.Fatal(err)}if bom[0] != 0xef || bom[1] != 0xbb || bom[2] != 0xbf {_, err = fd.Seek(0, 0) // Not a BOM -- seek back to the beginningif err != nil {log.Fatal(err)}}// The next read operation on fd will read real data// ...
}

完成的例子：

package mainimport ("encoding/csv""io""log""monorepo/service/autotable/common/logger""os"
)func main() {fileName := "/mnt/result.csv"// 准备读取文件fs, err := os.OpenFile(fileName, os.O_RDWR|os.O_CREATE, os.ModePerm)if err != nil {logger.Log.Errorf("can not open the file, err is: %s", err)}defer fs.Close()bom := make([]byte, 3)_, err = io.ReadFull(fs, bom[:])if err != nil {log.Fatal(err)}if bom[0] != 0xef || bom[1] != 0xbb || bom[2] != 0xbf {_, err = fs.Seek(0, 0) // Not a BOM -- seek back to the beginningif err != nil {log.Fatal(err)}}content := make([][]string, 0)r := csv.NewReader(fs)//针对大文件，一行一行的读取文件for {row, err := r.Read()if err != nil && err != io.EOF {logger.Log.Infof("can not read, err is: %s", err)continue}if err == io.EOF {break}content = append(content, row)}logger.Log.Infof("len:%s", len(content))
}
