从0开始用fyne写一个 ldap admin tools -- 连接ldap

1. 安装ldap

   $ docker pull osixia/openldap
   $ docker run --name openldap-container --detach \                                       
    --env LDAP_ORGANISATION="wanna" \
    --env LDAP_DOMAIN="wanna.com" \
    --env LDAP_ADMIN_PASSWORD="123456" \
    -p 389:389 \
    osixia/openldap

2. ldap添加数据
3. 连接ldap并查询数据
   代码地址
   效果：

代码如下：

    package main

    import (
        "crypto/tls"
        "fmt"
        "fyne.io/fyne/v2"
        "fyne.io/fyne/v2/app"
        "fyne.io/fyne/v2/container"
        "fyne.io/fyne/v2/widget"
        "github.com/go-ldap/ldap/v3"
    )

    // LDAP连接函数
    func connectToLDAP(server string, port int, username, password string) (*ldap.Conn, error) {
        l, err := ldap.DialURL(fmt.Sprintf("%s:%d", server, port), ldap.DialWithTLSConfig(&tls.Config{InsecureSkipVerify: true}))

        if err != nil {
            return nil, err
        }

        _, err = l.SimpleBind(&ldap.SimpleBindRequest{
            Username: username, // cn=admin,dc=sicau,dc=edu,dc=cn
            Password: password, // admin
        })
        if err != nil {
            return nil, err
        }
        return l, nil
    }

    // 查询LDAP数据
    func searchLDAP(l *ldap.Conn, baseDN, filter string) ([]*ldap.Entry, error) {
        searchRequest := ldap.NewSearchRequest(
            baseDN,
            ldap.ScopeWholeSubtree, ldap.NeverDerefAliases, 0, 0, false,
            filter,
            []string{"dn", "cn", "mail"}, // 您可以根据需要调整属性
            nil,
        )

        sr, err := l.Search(searchRequest)
        if err != nil {
            return nil, err
        }

        return sr.Entries, nil
    }

    func main() {
        // 初始化Fyne应用
        myApp := app.New()
        myWindow := myApp.NewWindow("LDAP Management Tool")

        // 用户名、密码和服务器输入框
        serverEntry := widget.NewEntry()
        serverEntry.SetPlaceHolder("LDAP Server Address")

        portEntry := widget.NewEntry()
        portEntry.SetPlaceHolder("LDAP Server Port")

        usernameEntry := widget.NewEntry()
        usernameEntry.SetPlaceHolder("Username")

        passwordEntry.SetPlaceHolder("Password")

        baseDNEntry := widget.NewEntry()
        baseDNEntry.SetPlaceHolder("Base DN")

        filterEntry := widget.NewEntry()
        filterEntry.SetPlaceHolder("Search Filter (e.g., (objectClass=*))")
        filterEntry.SetText("(objectClass=*)")

        resultLabel := widget.NewLabel("")

        // 搜索按钮
        searchButton := widget.NewButton("Search", func() {
            server := serverEntry.Text
            port := 389 // 默认端口
            fmt.Sscanf(portEntry.Text, "%d", &port)
            username := usernameEntry.Text
            password := passwordEntry.Text
            baseDN := baseDNEntry.Text
            filter := filterEntry.Text

            conn, err := connectToLDAP(server, port, username, password)
            if err != nil {
                resultLabel.SetText(fmt.Sprintf("Connection failed: %v", err))
                return
            }
            defer conn.Close()

            entries, err := searchLDAP(conn, baseDN, filter)
            if err != nil {
                resultLabel.SetText(fmt.Sprintf("Search failed: %v", err))

            // 显示结果
            result := "Results:\n"
            for _, entry := range entries {
                result += fmt.Sprintf("DN: %s\nCN: %s\nMail: %s\n\n", entry.DN, entry.GetAttributeValue("cn"), entry.GetAttributeValue("mail"))
            }
            resultLabel.SetText(result)
        })

        // 布局
        content := container.NewVBox(
            serverEntry,
            portEntry,
            usernameEntry,
            passwordEntry,
            baseDNEntry,
            filterEntry,
            searchButton,
            resultLabel,
        )

        myWindow.SetContent(content)
        myWindow.Resize(fyne.NewSize(400, 400))
        myWindow.ShowAndRun()
    }
