Question

有没有办法从HTML获取用户输入，并使用python将输入运行到SQL数据库？输入是否需要解析？我希望用户能够键入商店名称，并让它返回相关的行

def search():
    store_search = request.form.get("store")
    if request.method == "POST":
        if not store_search:
            return "please type in a store!"
        else:
            c = conn.cursor()
            c.execute("SELECT * FROM stores WHERE store_name= 'store_search'")
            rows = c.fetchall()
            for eachRow in rows:
                return row
    else:
return render_template("search.html")

HTML：

{% extends "main_page.html" %}
{% block title %}
Search
{% endblock %}

{% block main %}
    <form action="{{ url_for('search') }}" method="post">
        <fieldset>
            <div class="form-group">
                <input autocomplete="off" autofocus class="form-control" 
                 name="store" placeholder="store" type="text"/>
            </div>
            <div class="form-group">
                <button class="btn btn-default" type="submit">search</button>
            </div>
            <div class="page-header">
                <h1>{{ store }}</h1>
            </div>
        </fieldset>
    </form>
{% endblock %}

您可以在RootViewController中创建一个简单的应用，用于接收用户输入并扫描flask中SELECT查询返回的项目：

首先，创建用户表单。您可以将sqlite3与jquery一起用于动态响应：

在ajax：

search.html

在<html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script> </head> <body> <input type='text' name='query' id='query'> <button type='button' id='search'>Search</button> <div id='results'></div> </body> <script> $(document).ready(function() { $('#search').click(function() { var text = $('#query').val(); $.ajax({ url: "/search", type: "get", data: {query: text}, success: function(response) { $("#results").html(response.html); }, error: function(xhr) { //Do Something to handle error } }); }); }); </script> </html>

app.py

如何通过Python＆amp;获取HTML用户输入和查询SQL？
