Pywebview是一個用于構(gòu)建網(wǎng)頁的Python庫,類似于Flask框架,但主要使用Python編寫而非HTML或JS,通過簡單的命令即可安裝和使用,支持創(chuàng)建自制或調(diào)用外部網(wǎng)頁界面,需要的朋友可以參考下

前言

pywebview是python的一個庫，類似于flask框架，這也是用來構(gòu)建網(wǎng)頁的軟件包，它的特點就是不用更多的和html語言和js語言，更多的使用python語言就可以完成網(wǎng)頁的創(chuàng)建和元素的監(jiān)聽該庫的簡介和示例，簡單使用看示例足夠，但是其中也不夠詳盡：https://pywebview.flowrl.com/

一、安裝pywebview

首先，確保已經(jīng)安裝了pywebview，可以通過以下命令進行安裝：

pip install pywebview

二、簡單使用

簡單的創(chuàng)建界面和一些基礎(chǔ)操作，這里不再贅述，也沒什么營養(yǎng)，官方示例都已給出，這里只貼上一些示例：

一個示例界面;

import webview

if __name__ == '__main__':
    # Create a standard webview window
    window = webview.create_window('Simple browser', 'https://pywebview.flowrl.com/hello')
    webview.start()

一個自制界面：

import webview

html = """
  <html>
    <head></head>
    <body>
      <h2>Links</h2>

      <p><a >Regular links</a> are opened in the application window.</p>
      <p><a  target='_blank'>target='_blank' links</a> are opened in an external browser.</p>

    </body>
  </html>
"""

if __name__ == '__main__':
    window = webview.create_window('Link types', html=html)
    webview.start()

調(diào)用的是外部界面：

import webview

if __name__ == '__main__':
    window = webview.create_window(title='Webview App', url="https://hailuoai.com/?type=chat&chatID=251739240281759747/", confirm_close=True,
                                   zoomable=True, vibrancy=True, width=1275, height=745)
    webview.start(user_agent='Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36 Edg/125.0.0.0',
                  debug=True)

于是可以從這幾個例子看出來，pywebview主要有兩種，可以是自制的網(wǎng)頁html參數(shù)，又或者是url的外部鏈接。

三、高級使用

主要是關(guān)于dom的元素創(chuàng)建選擇何使用：按鈕等等，關(guān)于bind函數(shù)

import random
import webview

rectangles = []

def random_color():
    red = random.randint(0, 255)
    green = random.randint(0, 255)
    blue = random.randint(0, 255)

    return f'rgb({red}, {green}, {blue})'

def bind(window):
    def toggle_disabled():
        disabled = None if len(rectangles) > 0 else True
        remove_button.attributes = { 'disabled': disabled }
        empty_button.attributes = { 'disabled': disabled }
        move_button.attributes = { 'disabled': disabled }

    def create_rectangle(_):
        color = random_color()
        rectangle = window.dom.create_element(f'<div class="rectangle" style="background-color: {color};"></div>', rectangle_container)
        rectangles.append(rectangle)
        toggle_disabled()

    def remove_rectangle(_):
        if len(rectangles) > 0:
            rectangles.pop().remove()
        toggle_disabled()

    def move_rectangle(_):
        if len(rectangle_container.children) > 0:
            rectangle_container.children[-1].move(circle_container)

    def empty_container(_):
        rectangle_container.empty()
        rectangles.clear()
        toggle_disabled()

    def change_color(_):
        circle.style['background-color'] = random_color()

    def toggle_class(_):
        circle.classes.toggle('circle')

    rectangle_container = window.dom.get_element('#rectangles')
    circle_container = window.dom.get_element('#circles')
    circle = window.dom.get_element('#circle')

    toggle_button = window.dom.get_element('#toggle-button')
    toggle_class_button = window.dom.get_element('#toggle-class-button')
    duplicate_button = window.dom.get_element('#duplicate-button')
    remove_button = window.dom.get_element('#remove-button')
    move_button = window.dom.get_element('#move-button')
    empty_button = window.dom.get_element('#empty-button')
    add_button = window.dom.get_element('#add-button')
    color_button = window.dom.get_element('#color-button')

    toggle_button.events.click += lambda e: circle.toggle()
    duplicate_button.events.click += lambda e: circle.copy()
    toggle_class_button.events.click += toggle_class
    remove_button.events.click += remove_rectangle
    move_button.events.click += move_rectangle
    empty_button.events.click += empty_container
    add_button.events.click += create_rectangle
    color_button.events.click += change_color

if __name__ == '__main__':
    window = webview.create_window(
        'DOM Manipulations Example', html='''
            <html>
                <head>
                <style>
                    button {
                        font-size: 100%;
                        padding: 0.5rem;
                        margin: 0.3rem;
                        text-transform: uppercase;
                    }

                    .rectangle {
                        width: 100px;
                        height: 100px;
                        display: flex;
                        justify-content: center;
                        align-items: center;
                        margin: 0.5rem;
                        border-radius: 5px;
                        background-color: red;
                    }

                    .circle {
                        border-radius: 50px;
                        background-color: red;
                    }

                    .circle:hover {
                        background-color: green;
                    }

                    .container {
                        display: flex;
                        flex-wrap: wrap;
                    }
                </style>
                </head>
                <body>
                    <button id="toggle-button">Toggle circle</button>
                    <button id="toggle-class-button">Toggle class</button>
                    <button id="color-button">Change color</button>
                    <button id="duplicate-button">Duplicate circle</button>
                    <button id="add-button">Add rectangle</button>
                    <button id="remove-button" disabled>Remove rectangle</button>
                    <button id="move-button" disabled>Move rectangle</button>
                    <button id="empty-button" disabled>Remove all</button>
                    <div id="circles" style="display: flex; flex-wrap: wrap;">
                        <div id="circle" class="rectangle circle"></div>
                    </div>

                    <div id="rectangles" class="container"></div>
                </body>
            </html>
        '''
    )
    webview.start(bind, window)

并且使用event可以監(jiān)聽按鈕等等的事件發(fā)生

并且是支持動態(tài)生成元素的：

with open(file_path, 'r', encoding='utf-8') as file:
    for line in file:
        count += 1
        window.dom.create_element(
            f"<input id='word{count}' writingsuggestions='true' type='text' class='editable-textbox'>111</input>"
        )
        temp = window.dom.get_element(f'#word{count}')
        line = line.rstrip('\n')
        temp.value = line
