在前面的文章中,我们一起学习了如何通过 Python 抓取东方财富网的实时股票数据,链接如下

用 Python 爬取股票实时数据

今天我们就在这个基础上,实现一个 Tkinter GUI 程序,完成无代码股票抓取!

首先对于 Tkinter 相信大家都是比较了解的,如果有小伙伴对于 Tkinter 的相关用法不是特别熟悉的话,可以看如下文章

Tkinter 入门之旅

首先我们先看一下 GUI 程序的最终效果

该程序共分三个区域:

  • 个股查询:用于查询某只股票的数据,可以查询1天或者多天数据
  • 批量查询:查询某个交易所所有股票的数据
  • 日志区域:打印抓取信息

下面我们就来看看该如何从头完成这个 GUI 程序

程序布局

首先就是程序布局,这里我们使用了 ttkbootstrap 库来美化整体程序

程序初始化部分

代码语言:javascript复制
import ttkbootstrap as ttk
from ttkbootstrap.constants import *
import tkinter.messagebox as messbox


class MainCreator(ttk.Window):
    def __init__(self):
        super().__init__("股票抓取工具", themename="solar", resizable=(False, False))
        self.configure_frame = ttk.Frame(self, padding=(10, 10, 5, 10))
        self.configure_frame.pack(side=LEFT, fill=BOTH, expand=YES)
        self.demo_frame = ttk.Frame(self, padding=(5, 10, 10, 10))
        self.demo_frame.pack(side=LEFT, fill=BOTH, expand=YES)

程序布局部分

代码语言:javascript复制
    def create_frame(self):
        """Create all the frame widgets"""
        container = ttk.Frame(self)
        container.pack(side=LEFT, fill=BOTH, expand=YES, padx=5)

        color_group = ttk.Labelframe(
            master=container, text="个股查询", padding=10
        )
        color_group.pack(fill=X, side=TOP)
        en_command = super().register(self.en_validate)
        self.en0 = ttk.Entry(color_group, width=5, text='', bootstyle='warning',
                             validate='key', validatecommand=(en_command, '%P'))
        self.en0.insert('0', 1)
        self.en0.config(state=DISABLED)
        ...

总体上来说,我们所有的组件都是从 ttk 当中实例化的,也就是直接复用了库 ttkbootstrap 的相关美化功能,使得我们的程序看起来更加高级美观

抓取与保存功能

下面我们编写股票抓取代码和对应的保存代码

股票抓取

代码语言:javascript复制
def get_A_mins(code):
    if code.startswith("3") or code.startswith("0"):
        url = shang_A_url.replace("%s", code)
    elif code.startswith("6"):
        url = shen_A_url.replace("%s", code)
    else:
        return False

    res = requests.get(url)
    result = res.text.split("cb_1659146437934_51841953")[1].split("(")[1].split(");")[0]
    result_json = json.loads(result)
    stock_data = result_json['data']
    return stock_data


def get_A_days(code):
    if code.startswith("3") or code.startswith("0"):
        url = shang_A_days.replace("%s", code)
    elif code.startswith("6"):
        url = shen_A_days.replace("%s", code)
    else:
        return False

    res = requests.get(url)
    result = res.text.split("cb_1659171393020_15037673")[1].split("(")[1].split(");")[0]
    result_json = json.loads(result)
    stock_data = result_json['data']
    return stock_data


def get_hsj(date):
    total_data = []
    try:
        for i in range(1, 5):
            res = requests.get(hsj_url.replace("%s", str(i)))
            result = res.text.split("jQuery112402508937289440778_1658838703304")[1].split("(")[1].split(");")[0]
            result_json = json.loads(result)
            stock_data = result_json['data']
            if stock_data:
                total_data.append(stock_data)
                saveFunc.save_data_hsj(stock_data['diff'], date)
            else:
                return total_data
        return total_data
    except Exception as e:
        return False


def get_Center():
    total_data = []
    for i in range(1, 20):
        res = requests.get(center_url.replace("%s", str(i)))
        result = res.text.split("jQuery112404177389105264733_1659176039486")[1].split("(")[1].split(");")[0]
        result_json = json.loads(result)
        center_data = result_json['data']
        if center_data:
            total_data.append(center_data)
        else:
            return total_data


def get_shang_A():
    pass


def get_shen_A():
    pass


def get_bei_A():
    pass

股票代码分为上交所,深交所和北交所以及大盘行情数据,所以我们分别编写函数进行处理

数据保存

代码语言:javascript复制
import os


def save_data_mins(data, date):
    Code = data['code']
    Name = data['name']
    if not os.path.exists(r"stock_data_%s_%s_%s_mins.csv" % (Code, Name, date)):
        with open("stock_data_%s_%s_%s_mins.csv" % (Code, Name, date), "a ", encoding='utf-8') as f:
            f.write("时间,最新价,成交量(手),成交额n")
            for i in data['trends']:

                time = i_list[0]
                Open = i_list[1]
                close = i_list[2]
                heigh = i_list[3]
                low = i_list[4]
                mount = i_list[5]
                count = i_list[6]
                amplitude = i_list[7]
                changePercent = i_list[8]
                change = i_list[9]
                turnoverRate = i_list[10]
                row = '{},{},{},{},{},{},{},{},{},{},{}'.format(
                    time,Open,close,heigh,low,mount,count,amplitude,changePercent,change,turnoverRate)
                f.write(row)
                f.write('n')
    else:
        ...

    if not os.path.exists(r'stock_data_%s.csv' % date):
        with open("stock_data_%s.csv" % date, "a ", encoding='utf-8') as f:
            f.write("股票代码,股票名称,最新价,涨跌幅,涨跌额,成交量(手),成交额,振幅,换手率,市盈率,量比,最高,最低,今开,昨收,市净率n")
            for i in data:
                Code = i["f12"]
                Name = i["f14"]
                Close = i['f2']
                ChangePercent = i["f3"]
                Change = i['f4']
                Volume = i['f5']
                Amount = i['f6']
                Amplitude = i['f7']
                TurnoverRate = i['f8']
                PERation = i['f9']
                VolumeRate = i['f10']
                Hign = i['f15']

                    Code,Name,Close,ChangePercent,Change,Volume,Amount,Amplitude,
                    TurnoverRate,PERation,VolumeRate,Hign,Low,Open,PreviousClose,PB)
                f.write(row)
                f.write('n')
    else:
        ...


def save_data_center():
    pass


def save_data_shang_A():
    pass

添加功能

接下来就是为布局好的 GUI 程序添加各种响应功能

个股查询按钮

为个股查询的抓取按钮绑定方法catch

代码语言:javascript复制
self.bt = ttk.Button(color_group, text='抓取', bootstyle='success', command=self.catch)

方法catch的定义如下

代码语言:javascript复制
    def catch(self):
        self.txt.yview_moveto(1)
        now = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')
        day = datetime.datetime.now().strftime('%Y-%m-%d')
        if self.cbvar.get() == 1:
            catch_day = self.en0.get()
            if self.en.get():
                code = self.en.get()
                result = catchFunc.get_A_days(code)
                if result:
                    saveFunc.save_data_days(result, catch_day)
                    self.txt.insert(ttk.INSERT, "抓取股票%s成功 %s" % (code, now))
                    self.txt.insert(ttk.INSERT, "n")
                    self.txt.update()
                    self.txt.yview_moveto(1)
                else:
                    print("股票代码错误")
                    messbox.showerror("股票代码错误", "请输入正确的股票代码!")
            else:
                print("请输入股票代码")
                messbox.showerror("股票代码为空", "请输入股票代码!")
        else:
        ...

批量查询开关

对于批量查询,我们是通过一个多选框开关控制的

代码语言:javascript复制
self.cb_batch = ttk.Checkbutton(cr_group, text="开启批量", variable=self.cbvar1, command=self.cb_button)

绑定的方法如下

代码语言:javascript复制
    def cb_button(self):
        if self.cbvar1.get() == 1:
            self.bt_batch.config(state=NORMAL)
        else:
            self.bt_batch.config(state=DISABLED)

以上就是程序的部分代码,让我们看一下整体效果吧
