以下是Playwright.devices('iPhone 12 Pro')函数如何使用python代码示例:
```
from playwright.sync_api import Playwright, sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch(headless=True)
context = browser.new_context(
**p.devices['iPhone 12 Pro'].as_dict())
page = context.new_page()
page.goto('https://www.google.com/')
print(page.title())
browser.close()
```
这段代码使用Playwright库中的sync_playwright函数以及chromium浏览器来启动一个headless浏览器,并使用Playwright.devices('iPhone 12 Pro')函数来设置浏览器的设备类型为iPhone 12 Pro。然后,使用新的上下文和页面导航到Google网站,打印页面标题,并关闭浏览器。

Playwright.devices()函数如何使用python代码示例
您好,使用Playwright.devices()函数获取设备信息的Python示例代码可以如下:
```
from playwright.sync_api import Playwright, sync_playwright
import random
# 随机获取一个设备信息
def random_device(playwright: Playwright) -> dict:
devices = playwright.devices
return devices[random.randint(0, len(devices)-1)]
with sync_playwright() as p:
# 初始化浏览器
browser = p.chromium.launch()
# 创建页面
page = browser.new_context(**random_device(p)).new_page()
# 在页面中执行操作
page.goto("https://www.baidu.com/")
page.fill("#kw", "playwright")
page.click("#su")
print(page.title())
# 关闭浏览器
browser.close()
```
以上代码示例演示了如何随机选择一个设备信息,并在页面中打开百度并搜索关键字“playwright”。请注意,此代码要求您已安装Playwright Python库,并已安装Playwright浏览器驱动程序。
Playwright.devices()函数如何使用 详细代码示例
为了使用 Playwright.devices() 函数,需要先在代码中引入 Playwright 库。然后,可以调用 Playwright.devices() 函数来获取可用设备的列表。以下是一个使用 Playwright.devices() 函数的代码示例:
```javascript
const { firefox } = require('playwright');
(async () => {
const devices = await firefox.devices();
console.log(devices);
})();
```
上面的示例代码使用 Firefox 浏览器,并调用了 Playwright.devices() 函数获取可用设备列表,并将其打印到控制台。
该函数返回的是一个对象数组,包含了 Playwright 支持的手机、平板电脑等各种设备规格的信息。每个设备规格都可以通过一个对象来表示,对象中包含了设备的名称、屏幕大小、像素比等属性。
例如,以下是一个设备规格对象的示例:
```javascript
{
"name": "iPhone 12",
"userAgent": "Mozilla/5.0 (iPhone; CPU iPhone OS 14_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0 Mobile/15E148 Safari/604.1",
"viewport": {
"width": 390,
"height": 844,
"deviceScaleFactor": 3,
"isMobile": true,
"hasTouch": true,
"isLandscape": false
}
}
```
上面的对象表示一个 iPhone 12 设备,其中包含了该设备的用户代理字符串、屏幕大小等信息。具体不同设备规格的属性可以参考 Playwright 的官方文档。
