项目简介

作品通过python+flask构建前端页面实现与用户的交互，其实现过程如下：

部分代码展示

1.后台进行股票查询与结果分析的代码：

# -*- coding:utf-8 -*-import urllib.requestdef get_stock(stock_no):    # 使用腾讯股票查询接口进行查询    f = urllib.request.urlopen('http://qt.gtimg.cn/q=s_' + str(stock_no))    res = f.read().decode('gbk')    f.close()    return resdef result_parse(result):    res_dict = {}    result_spl = result[14:-3].split('~')    res_dict['stock_name'] = result_spl[1]    res_dict['stock_no'] = result_spl[2]    res_dict['current_price'] = result_spl[3]    res_dict['fluctuation'] = result_spl[4]    res_dict['fluctuation_by_percent'] = result_spl[5]    res_dict['volume'] = result_spl[6]    res_dict['turnover'] = result_spl[7]    return res_dictdef stock_check(stock_no):    if len(stock_no) != 6:        return 0    no_first = stock_no[0]    if int(no_first) == 6:        code = 'sh' + stock_no        return code    elif (int(no_first) == 0) | (int(no_first) == 3):        code = 'sz' + stock_no        return code    else:        return 0

2.flask交互代码：

# coding:utf8import configparserimport flaskfrom flask import render_templatefrom stork_query import stock_check, result_parse, get_stockapp = flask.Flask(__name__)@app.route('/', methods=['GET', 'POST'])def homepage():    if flask.request.method == 'GET':        result = {}        return render_template("homepage.html", result=result)    elif flask.request.method == 'POST'and flask.request.form.get('query', None) == "查询":        stock_no = flask.request.form['storkcode']        code = stock_check(stock_no)        if code != 0:            result = result_parse(get_stock(code))            return render_template("homepage.html", result=result)        else:            return render_template("homepage.html", warning="请输入正确的股票代码")if __name__ == '__main__':    app.run(debug=True, host='127.0.0.1', port=4501)
