本文介绍了将数据从HTML表单发送到Flask中的Python脚本的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

  def cmd_wui(argv,path_to_tx):
运行Web UI。$ $ $ b从瓶子导入烧瓶,闪光灯,jsonify,render_template,请求
导入webbrowser
app =烧瓶(__ name__)


@ app.route('/ tx / index /')
def index():
加载启动页面,在其中选择项目文件夹
或加载历史记录项目从本地数据库。$
从txclib导入get_version
txc_version = get_version()
prj = project.project(path_to_tx)

#让我们创建一个资源列表从我们的配置文件
res_list = []
prev_proj =''
for idx,res in enumerate(prj.get_resource_list()):
hostname = prj.get_resource_host(res)
username,password = prj.getset_host_credentials(hostname)
return render_template('init.html',txc_version = txc_version,用户名=用户名)

另外,我在init.html中有一个HTML表单:

 < form> 
< input type =textid =projectFilepathsize =40placeholder =找到您的项目文件>
< input type =buttonid =spotButtonvalue =Spot>
< / form>

当用户点击变量spotButton时,如何从projectFilepath传递用户输入在我的python脚本?



我是Python和Flask的新手,所以如果我犯了什么错误,请原谅我。

表单标记需要设置两个属性:


  1. action :表单数据在提交时发送到的URL。使用 url_for 生成。如果显示表单和处理数据的URL句柄相同,则可以省略。 查询字符串(GET)或表单数据(POST)。

添加一个视图来处理表单数据:

  @ app.route('/ handle_data',methods = ['POST'])
def handle_data():
projectpath = request.form ['projectFilepath']
#你的代码
#返回一个响应

将表单的动作设置为该视图的网址:

 < form action ={{url_for('handle_data')}}method =post> 
< input type =textname =projectFilepath>
< input type =submit>
< / form>


I have the code below in my Python script:

def cmd_wui(argv, path_to_tx):
    """Run a web UI."""
    from flask import Flask, flash, jsonify, render_template, request
    import webbrowser
    app = Flask(__name__)


    @app.route('/tx/index/')
    def index():
        """Load start page where you select your project folder
        or load history projects from local DB."""
        from txclib import get_version
        txc_version = get_version()
        prj = project.Project(path_to_tx)

        # Let's create a resource list from our config file
        res_list = []
        prev_proj = ''
        for idx, res in enumerate(prj.get_resource_list()):
                hostname = prj.get_resource_host(res)
        username, password = prj.getset_host_credentials(hostname)
        return render_template('init.html', txc_version=txc_version, username=username)

Also, I have an HTML form in init.html:

<form>
<input type="text" id="projectFilepath" size="40" placeholder="Spot your project files">
<input type="button" id="spotButton" value="Spot">
</form>

How can I pass the user input from "projectFilepath" when a user clicks "spotButton" on a variable in my python script?

I'm new in Python and Flask, so forgive me if I make any mistakes.

解决方案

The form tag needs two attributes set:

  1. action: The URL that the form data is sent to on submit. Generate it with url_for. It can be omitted if the same URL handles showing the form and processing the data.
  2. method: Whether to submit the data as a query string (GET) or form data (POST).

Add a view to handle the form data:

@app.route('/handle_data', methods=['POST'])
def handle_data():
    projectpath = request.form['projectFilepath']
    # your code
    # return a response

Set the form's action to that view's URL:

<form action="{{ url_for('handle_data') }}" method="post">
    <input type="text" name="projectFilepath">
    <input type="submit">
</form>
