python语言可换主题ttk界面从服务器拿日志文件

简单界面tkinter库，稍微美化界面就安装一下ttkthemes

pip3 install ttkthemes

简单使用

themes = ttkthemes.THEMES
        themesName = themes[random.randint(0, len(themes) - 1)]
        print('主题 ' + themesName)
        top = ttkthemes.ThemedTk(theme=themesName, toplevel=True, themebg=True)
        # top = Tk()

这样代码只能是启动的时候就定下来主题，运行中要更换记得要同时设置一下背景和字体

采用vb插件画好基础界面，使用中又添加了些小功能

    # The class will create all widgets for UI.
    def __init__(self, master=None):

        # To center the window on the screen.
        w = 800
        h = 300
        ws = self.master.winfo_screenwidth()
        hs = self.master.winfo_screenheight()
        x = (ws / 2) - (w / 2)
        y = (hs / 2) - (h / 2)
        self.master.geometry('%dx%d+%d+%d' % (w, h, x, y))

        self.createWidgets()
        self.Combo1.current(0)

    def createWidgets(self):

        self.Combo1.setText = lambda x: self.Combo1Var.set(x)
        self.Combo1.text = lambda: self.Combo1Var.get()
        self.Combo1.place(relx=0.1, rely=0.054, relwidth=0.22)

        self.Command1.setText = lambda x: self.Command1Var.set(x)
        self.Command1.text = lambda: self.Command1Var.get()
        self.Command1.place(relx=0.82, rely=0.7, relwidth=0.14)

        self.Text1 = Text(self.top, font=self.Text1Font)
        self.Text1.place(relx=0.026, rely=0.187, relwidth=0.776, relheight=0.726)
        self.Text1.insert('1.0', 'Text1')

        self.topRadioVar = StringVar(value='1')
        self.style.configure('TOption2.TRadiobutton', font=self.Text1Font)
        self.Option2 = Radiobutton(self.top, text='缓存', value='1', variable=self.topRadioVar, style='TOption2.TRadiobutton')
        self.Option2.setValue = lambda x: self.topRadioVar.set('1' if x else '0')
        self.Option2.value = lambda: 1 if self.topRadioVar.get() == '1' else 0
        self.Option2.place(relx=0.43, rely=0.054, relwidth=0.09, relheight=0.1)

        self.Combo2Var = StringVar(value='arc')
        self.Combo2 = Combobox(self.top, text='arc', textvariable=self.Combo2Var, values=self.Combo2List, font=self.Text1Font)

        self.Combo2Var.trace('w', self.Combo2_Change)
        self.Combo2.bind('<>', self.Combo2_Change)

然后是具体调用功能代码

class Application(Application_ui):
    # The class will implement callback function for events and your logical code.
    def __init__(self, master=None):
        Application_ui.__init__(self, master)
        self.host_ip = extract_ip()
        self.Combo1.set(self.host_ip)

    def change_theme(root, themes_name):
        """
        更改风格
        """
        print(themes_name)
        style = ttkthemes.ThemedStyle(root)
        style.set_theme(themes_name)
        color = Style(root).lookup("TFrame", "background", default="white")
        root.top.config(background=color)
        root.style.configure('.', font=root.Text1Font)

    def EV_WM_DELETE_WINDOW(self, event=None):
        if askyesno(title='退出确认', message='请问是否要退出？'):
            self.master.destroy()

    def Command2_Cmd(self, event=None):
        ip = self.Combo1.get()
        print(ip)
        r = requests.get('http://%s:8080/uploadFile?ext=1&type=%s' % (ip, self.topRadioVar.get()))
        file = r.content.decode()
        self.Text1.insert(INSERT, file + '\n')
        if ip == self.host_ip:
            os.system('scp qzc@%s:%s %s' % (ip, file, os.getcwd()))
        else:
            os.system('scp root@%s:%s %s' % (ip, file, os.getcwd()))
        self.Text1.insert(INSERT, os.getcwd() + '\n')

    def Combo2_Change(self, *args):
        print(self.Combo2.get())
        self.change_theme(self.Combo2.get())

    def Command1_Cmd(self, event=None):
        e = askyesno(title='退出确认', message='请问是否要退出？')
        if e:
            self.quit()

原理很简单，通过http接口拿到服务器文件名，然后用scp命令把文件下载到本地，记得是通过命令ssh-copy-id -i [email protected]事先向服务器认证过了，否则拿文件时因为没输入密码失败

用到一个查询本机ip地址公用函数

def extract_ip():
    """
    查询本机ip地址
    :return:
    """
    try:
        s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s.connect(('10.255.255.255', 1))
        ip = s.getsockname()[0]
    except Exception:
        ip = '127.0.0.1'
    finally:
        s.close()
    return ip

可以编译成独立文件脱离python环境使用

pyinstaller -F -w getjclog.py

linux下面文件本身没有图标，编译命令就不需要加ico了，运行起来如果想再任务栏显示图标，可以放一个sd.png文件到可执行文件同路径下
