How do I set the page viewport size using Scrapy Playwight?
问题
我没有找到关于这个问题的满意答案。我只想在请求之前将视口设置为1080*19200（是的，1920 * 10），以模拟那个尺寸的屏幕。
使用Scrapy Playwright是否可能实现这一点？如果可以，我该如何做到？
英文:
I didn't find any satisfactory answer about this. All I want is just set the viewport to 1080*19200 (yes, 1920 * 10) before the request to simulate a screen of that size.
Is this even possible using Scrapy Playwright? If so, how do i do that?

有多种方法可以实现这个：
- 在上下文中。Playwright的
Browser.new_context方法接受一个viewport参数，可以在PLAYWRIGHT_CONTEXTS设置中使用：
# settings.pyPLAYWRIGHT_CONTEXTS = {"default": {"viewport": {"width": 19200,"height": 1080,},},}
- 在页面中。你可以在页面初始化回调函数中调用
Page.set_viewport_size：
async def init_page(page, request):await page.set_viewport_size({"width": 19200, "height": 1080})
yield scrapy.Request(url="https://example.org",meta={"playwright": True,"playwright_page_init_callback": init_page,},)
- 在页面中，使用
PageMethod：
from scrapy_playwright.page import PageMethod
yield scrapy.Request(url="https://example.org",meta={"playwright": True,"playwright_page_methods": [PageMethod("set_viewport_size", {"width": 19200, "height": 1080}),],},)
英文:
There are multiple ways of doing this:
- In the context. Playwright's Browser.new_context method takes a
viewportargument, which can be used in thePLAYWRIGHT_CONTEXTSsetting:
# settings.pyPLAYWRIGHT_CONTEXTS = {"default": {"viewport": {"width": 19200,"height": 1080,},},}
- In the page. You can call
Page.set_viewport_sizefrom a page init callback:
async def init_page(page, request):await page.set_viewport_size({"width": 19200, "height": 1080})
yield scrapy.Request(url="https://example.org",meta={"playwright": True,"playwright_page_init_callback": init_page,},)
- In the page, with a
PageMethod:
from scrapy_playwright.page import PageMethod
yield scrapy.Request(url="https://example.org",meta={"playwright": True,"playwright_page_methods": [PageMethod("set_viewport_size", {"width": 19200, "height": 1080}),],},)
