golang读取文本文件示例

一般文件比较小的话可以将文件全部读入内存中,然后转换成string再按行分割一下

func GetFileContentAsStringLines(filePath string) ([]string, error) {logger.Infof("get file content as lines: %v", filePath)result := []string{}b, err := ioutil.ReadFile(filePath)if err != nil {logger.Errorf("read file: %v error: %v", filePath, err)return result, err}s := string(b)for _, lineStr := range strings.Split(s, "\n") {lineStr = strings.TrimSpace(lineStr)if lineStr == "" {continue}result = append(result, lineStr)}logger.Infof("get file content as lines: %v, size: %v", filePath, len(result))return result, nil}
