Python playwright 可以使用以下步骤模拟手机浏览器:
1. 导入 Playwright 库和所需的设备描述符。例如:
```python
from playwright.sync_api import Playwright, sync_playwright
from playwright.devices import DeviceDescriptors
```
2. 创建 Playwright 的实例并声明要使用的浏览器类型。例如:
```python
with sync_playwright() as playwright:
browser = playwright.chromium.launch()
context = browser.new_context(
**DeviceDescriptors['iPhone 11 Pro']
)
```
3. 访问指定的网址并等待加载完成。例如:
```python
page = context.new_page()
page.goto('https://www.example.com')
page.wait_for_selector('body.loaded')
```
4. 模拟用户与页面交互,例如在输入框中输入文本和单击按钮等操作。例如:
```python
input_selector = 'input[type="text"]'
search_selector = 'button[type="submit"]'
page.fill(input_selector, 'example search')
page.click(search_selector)
```
5. 关闭页面和浏览器实例。例如:
```python
page.close()
browser.close()
```
通过这些步骤,您可以使用 Python playwright 模拟手机浏览器浏览网页并执行各种自动化任务。
