使用deepseek实现go语言，读取文本文件的功能，要求支持ascii，utf-8等多种格式自适应

使用 deepseek实现 go语言，读取文本文件的功能，要求支持 ascii，utf-8 等多种格式自适应我要用 chatgpt，也问过，但是比 deepseek 还是差一个级别，具体如下： package main import ( "bufio" "bytes" "fmt" "golang.org/x/net/html/charset" "golang.org/x/text/encoding/unicode" "golang.org/x/text/transform" "io" "os" "strings" ) // detectBOM 检测常见的BOM类型并返回编码名称和BOM长度 func detectBOM(b []byte) (enc string, bomLen int) { // UTF-8 BOM if len(b) >= 3 && b[0] == 0xEF && b[1] == 0xBB && b[2] == 0xBF { return "UTF-8 BOM", 3 } // UTF-16 LE/BE if len(b) >= 2 { if b[0] == 0xFF && b[1] == 0xFE { return "UTF-16LE", 2 } if b[0] == 0xFE && b[1] == 0xFF { return "UTF-16BE", 2 } } // UTF-32 LE/BE (可能不常见，但示例处理) if len(b) >= 4 { if b[0] == 0xFF && b[1] == 0xFE && b[2] == 0x00 && b[3] == 0x00 { return "UTF-32LE", 4 } if b[0] == 0x00 && b[1] == 0x00 && b[2] == 0xFE && b[3] == 0xFF { return "UTF-32BE", 4 } } return "", 0 } // ReadTextFile 逐行读取文本文件，自动处理编码和BOM func ReadTextFile(filename string) ([]string, error) { file, err := os.Open(filename) if err != nil { return nil, err } defer file.Close() // 读取前4字节用于BOM检测 bomBuf := make([]byte, 4) n, err := file.Read(bomBuf) if err != nil && err != io.EOF { return nil, err } bomBuf = bomBuf[:n] enc, bomLen := detectBOM(bomBuf) var source io.Reader var decoder transform.Transformer if enc != "" { // 处理带BOM的情况 remaining := bomBuf[bomLen:] source = io.MultiReader(bytes.NewReader(remaining), file) switch enc { case "UTF-8 BOM": decoder = unicode.UTF8.NewDecoder() case "UTF-16LE": decoder = unicode.UTF16(unicode.LittleEndian, unicode.IgnoreBOM).NewDecoder() case "UTF-16BE": decoder = unicode.UTF16(unicode.BigEndian, unicode.IgnoreBOM).NewDecoder() default: return nil, fmt.Errorf("unsupported encoding: %s", enc) } } else { // 无BOM时检测编码 source = io.MultiReader(bytes.NewReader(bomBuf), file) br := bufio.NewReader(source) // 读取前1024字节进行编码检测 detectBuf, err := br.Peek(1024) if err != nil && err != io.EOF { return nil, err } // 自动检测编码 e, _, _ := charset.DetermineEncoding(detectBuf, "") if e == nil { e = unicode.UTF8 // 默认UTF-8 } decoder = e.NewDecoder() source = br } // 创建UTF-8转换Reader utf8Reader := transform.NewReader(source, decoder) scanner := bufio.NewScanner(utf8Reader) var lines []string for scanner.Scan() { lines = append(lines, scanner.Text()) } if err := scanner.Err(); err != nil { return nil, err } return lines, nil } // 过滤双引号已经前后空格 func Filter(lists []string) []string { r := make([]string, 0, len(lists)) for _, list := range lists { item := strings.TrimSpace(list) if len(item) >= 2 { first := item[0] last := item[len(item)-1] if first == last && first == '"' { r = append(r, strings.TrimSpace(item[1:len(item)-1])) } else { r = append(r, item) } } else { r = append(r, item) } } return r } func main() { name := "./csv/export.csv" lines, err := ReadTextFile(name) if err != nil { fmt.Println("读取错误：" + err.Error()) return } for _, line := range lines { lists := Filter(strings.Split(line, "\t")) fmt.Println(line + " ==> " + strings.Join(lists, ",")) } }
