在Python Playwright中,可以使用`browser.new_context()`方法创建一个新的浏览器上下文,并通过`set_permissions()`方法设置该上下文的权限。其中,`set_permissions()`方法可以接受一个`origins`参数,用于设置允许的源。
以下是设置`origins`的示例代码:
```python
from playwright.sync_api import sync_playwright
def set_origins():
with sync_playwright() as playwright:
browser = playwright.chromium.launch()
context = browser.new_context()
# 设置允许的源
context.set_permissions(origin="https://example.com")
# 在此上下文中执行其他操作
browser.close()
set_origins()
```
在上述示例中,我们使用`set_permissions()`方法将`https://example.com`添加到允许的源列表中。你可以根据需要设置多个源,只需将它们作为参数传递给`set_permissions()`方法即可。

python playwright设置cookie
使用Playwright可以使用以下代码设置cookie:
```python
from playwright.sync_api import Playwright, sync_playwright
with sync_playwright() as p:
browser = p.chromium.launch()
context = browser.new_context()
page = context.new_page()
# 设置cookie
cookies = [{"name": "name1", "value": "value1"}, {"name": "name2", "value": "value2"}]
page.set_cookie(*cookies)
# 打开网页
page.goto('https://www.example.com')
# 关闭浏览器
browser.close()
```
其中 `set_cookie` 函数接受一个或多个 cookie 对象作为参数,每个 cookie 对象应该包含 `name` 和 `value` 字段。可以传递多个 cookie 对象,只需要在前面加上 `*`,例如 `page.set_cookie(*cookies)`。在设置完cookie后,可以通过 `page.goto` 方法打开需要使用这些cookie的网页。
python playwright选取class为python playwright的ul标签
要使用Python Playwright选择class为"python playwright"的ul标签,可以按照以下步骤进行操作:
1. 导入Playwright库:
```python
from playwright.sync_api import sync_playwright
```
2. 启动Playwright并创建一个浏览器实例:
```python
with sync_playwright() as playwright:
browser = playwright.chromium.launch()
page = browser.new_page()
```
3. 打开目标网页:
```python
page.goto("https://example.com")
```
4. 使用CSS选择器选择目标元素:
```python
ul_element = page.query_selector('ul.python.playwright')
```
这里使用了CSS选择器,其中`ul.python.playwright`表示选择class为"python playwright"的ul标签。
5. 获取元素的文本内容:
```python
ul_text = ul_element.inner_text()
print(ul_text)
```
6. 关闭浏览器实例:
```python
browser.close()
```
