排序没有生效 db := common.DB.Session(&gorm.Session{}) //升序降序 feild := ctx.DefaultQuery("feild", "id") order := ctx.Query("order") if order == "desc" { feild = feild + " DESC" } else { feild = feild + " ASC" } var res *gorm.DB if s == 5 { common.DB.Model(&req).Debug().Where("name LIKE ?", "%"+name+"%").Where("responsible_unit LIKE ?", "%"+unit+"%").Count(&count) res = db.Order(feild).Scopes(Paginate(page, pageSize)).Where("name LIKE ?", "%"+name+"%").Where("responsible_unit LIKE ?", "%"+unit+"%").Find(&lists) } else { common.DB.Model(&req).Where("status=?", s).Where("name LIKE ?", "%"+name+"%").Where("responsible_unit LIKE ?", "%"+unit+"%").Count(&count) res = db.Order(feild).Scopes(Paginate(page, pageSize)).Where("status=?", s).Where("name LIKE ?", "%"+name+"%").Where("responsible_unit LIKE ?", "%"+unit+"%").Find(&lists) }

根据您提供的代码片段，我看到您尝试对数据库查询结果进行排序。在这段代码中，您通过 `db.Order(feild)` 来设置排序字段。

如果排序没有生效，可能有几个原因需要检查：

1. 确保 `feild` 变量的值正确。您可以打印或调试查看 `feild` 的值是否正确。
2. 确保您的数据库表中存在与 `feild` 对应的列名。如果列名不存在或拼写错误，排序将无效。
3. 确保数据库连接和查询语句没有其他错误。您可以通过打印或调试来验证数据库查询是否正确执行。

如果这些步骤都没有解决问题，建议提供更多上下文或错误信息以便更好地帮助您解决问题。

改进代码func TracingList(ctx *gin.Context) { resp := models.Response{ Code: 0, Msg: "success", } t, _ := strconv.Atoi(ctx.Query("t")) label, _ := strconv.Atoi(ctx.Query("label")) page, _ := strconv.Atoi(ctx.DefaultQuery("page", "1")) pageSize, _ := strconv.Atoi(ctx.DefaultQuery("pageSize", "10")) code := ctx.Query("code") //设施类型 if len(code) == 0 { resp.Code = 400 resp.Msg = "请输入code值" ctx.JSON(400, resp) return } type Total struct { gorm.Model Type int16 Source int16 Explanation string Label int16 FacilityID string } db := common.DB.Session(&gorm.Session{}) if t < 0 || t > 5 { var req interface{} switch t { case 0: req = []*Total{} case 1: req = []*models.Flaw{} case 2: req = []*models.Issue{} case 3: req = []*models.Record{} case 4: req = []*models.Quality{} case 5: req = []*models.Inspection{} } //查询并分页 if t < 1 || t > 5 { res := db.Scopes(models.Paginate(page, pageSize)).Where("facility_id=?", code).Find(&req) if res.RowsAffected == 0 { resp.Code = 400 resp.Msg = "记录不存在" ctx.JSON(400, resp) return } } else { res := db.Scopes(models.Paginate(page, pageSize)).Raw("SELECT * FROM flaws WHERE facility_id = ?

以下是改进的代码：

func TracingList(ctx *gin.Context) {
    resp := models.Response{
        Code: 0,
        Msg:  "success",
    }

    code := ctx.Query("code")
    if len(code) == 0 {
        resp.Code = 400
        resp.Msg = "请输入code值"
        ctx.JSON(400, resp)
        return
    }

    t, err := strconv.Atoi(ctx.Query("t"))
    if err != nil || t < 0 || t > 5 {
        resp.Code = 400
        resp.Msg = "无效的参数t"
        ctx.JSON(400, resp)
        return
    }

    label, err := strconv.Atoi(ctx.Query("label"))
    if err != nil || label < 1 || label > 4 {
        resp.Code = 400
        resp.Msg = "无效的参数label"
        ctx.JSON(400, resp)
        return
    }

    page, err := strconv.Atoi(ctx.DefaultQuery("page", "1"))
    if err != nil || page < 1 {
        resp.Code = 400
        resp.Msg = "无效的参数page"
        ctx.JSON(400, resp)
        return
    }

    pageSize, err := strconv.Atoi(ctx.DefaultQuery("pageSize", "10"))
    if err != nil || pageSize < 1 {
        resp.Code = 400
        resp.Msg = "无效的参数pageSize"
        ctx.JSON(400, resp)
        return
    }

    var req interface{}
    switch t {
    case 0:
        req = []*Total{}
    case 1:
        req = []*models.Flaw{}
    case 2:
        req = []*models.Issue{}
    case 3:
        req = []*models.Record{}
    case 4:
        req = []*models.Quality{}
    case 5:
        req = []*models.Inspection{}
    }

    db := common.DB.Session(&gorm.Session{})
    res := db.Scopes(models.Paginate(page, pageSize)).Where("facility_id=?", code)
    if t >= 1 && t <= 5 {
        res = res.Table("flaws").Where("facility_id=?", code).
            Or("facility_id=?", code).
            Or("facility_id=?", code).
            Or("facility_id=?", code).
            Or("facility_id=?", code)
    }
    res.Find(req)
    if res.RowsAffected == 0 {
        resp.Code = 400
        resp.Msg = "记录不存在"
        ctx.JSON(400, resp)
        return
    }

    resp.Data = req
    ctx.JSON(200, resp)
}

主要改进包括：

1. 对输入的参数进行了有效性检查，如 t、label、page 和 pageSize 都需要为正整数，code 不能为空。
2. 使用了 Go 语言内置的错误处理机制，当参数无效时，返回错误信息。
3. 将 SQL 查询语句拆分为两段，根据 t 的值判断使用哪一段，避免了使用 Raw() 方法的安全隐患。
4. 代码结构更加清晰，易于阅读和维护。

func SaveOS() { var data []model.HistoryMessages gorm.DB.Find(&data) file, err := os.Create("data.csv") if err != nil { panic(err) } defer file.Close() writer := csv.NewWriter(file) defer writer.Flush() writer.Write([]string{"SendId", "ReceiveId", "Object", "Media", "Content", "SendTime"}) for _, message := range data { record := []string{ message.SendId, message.ReceiveId, message.Object, message.Media, message.Content, message.SendTime.Format("2006-01-02 15:04:05"), } writer.Write(record) } }帮我把这代码生成的文件使用aes加密，写出完整代码

好的，请参考下面的代码，使用AES加密文件：

import (
    "crypto/aes"
    "crypto/cipher"
    "crypto/rand"
    "encoding/csv"
    "os"
    "io"
    "log"
)

func SaveOS() {
    var data []model.HistoryMessages
    gorm.DB.Find(&data)

    // 创建文件并打开
    file, err := os.Create("data.csv")
    if err != nil {
        panic(err)
    }
    defer file.Close()

    // 创建CSV writer
    writer := csv.NewWriter(file)
    defer writer.Flush()

    // 写入表头
    writer.Write([]string{"SendId", "ReceiveId", "Object", "Media", "Content", "SendTime"})

    // 写入数据
    for _, message := range data {
        record := []string{
            message.SendId,
            message.ReceiveId,
            message.Object,
            message.Media,
            message.Content,
            message.SendTime.Format("2006-01-02 15:04:05"),
        }
        writer.Write(record)
    }

    // 打开CSV文件并读取数据
    csvfile, err := os.Open("data.csv")
    if err != nil {
        log.Fatalln("Unable to read input file " + "data.csv")
    }
    defer csvfile.Close()
    reader := csv.NewReader(csvfile)
    records, err := reader.ReadAll()
    if err != nil {
        log.Fatalln("Unable to parse file " + "data.csv")
    }

    // 生成随机密钥和向量
    key := make([]byte, 32)
    if _, err := rand.Read(key); err != nil {
        panic(err.Error())
    }
    iv := make([]byte, aes.BlockSize)
    if _, err := rand.Read(iv); err != nil {
        panic(err.Error())
    }

    // 创建加密器
    block, err := aes.NewCipher(key)
    if err != nil {
        panic(err.Error())
    }
    ciphertext := make([]byte, aes.BlockSize+len(records))
    stream := cipher.NewCTR(block, iv)
    stream.XORKeyStream(ciphertext[aes.BlockSize:], []byte(records))

    // 写入加密后的数据和密钥、向量到文件
    outfile, err := os.Create("data.enc")
    if err != nil {
        log.Fatalln("Unable to create output file " + "data.enc")
    }
    defer outfile.Close()

    // 写入密钥和向量
    outfile.Write(iv)
    outfile.Write(key)

    // 写入加密后的数据
    _, err = outfile.Write(ciphertext)
    if err != nil {
        log.Fatalln("Unable to write encrypted data to output file")
    }
}

注意：这个代码中使用了AES-CTR模式进行加密，同时生成了随机的密钥和向量。加密后的数据保存在" data.enc"文件中，同时也保存了密钥和向量。在解密时，需要使用相同的密钥和向量才能成功解密。
