How can I disable cache in puppeteer?
提问by Nagarjun Prasad
I want to disable cache in puppeteer, can anyone please tell me how I can do so? I found this page.setCacheEnabled(enabled)but I couldn't understand how to use the same.
我想在 puppeteer 中禁用缓存，谁能告诉我我该怎么做？我找到了这个，page.setCacheEnabled(enabled)但我不明白如何使用它。
I am aware that the browser is launched without cache or cookies but in my case the browser is always running in the background thus need a different solution.
我知道浏览器是在没有缓存或 cookie 的情况下启动的，但在我的情况下，浏览器总是在后台运行，因此需要不同的解决方案。

According to the puppeteer docs you can use await page.setCacheEnabled(enabled)
根据 puppeteer 文档，您可以使用 await page.setCacheEnabled(enabled)
This was added back in December. See Git Hub issue #1609
这是在 12 月添加的。参见 Git Hub 问题 #1609
If you look at the commit changesthere is a test e.g.
如果您查看提交更改，则有一个测试，例如
await page.goto(SOMEURL);
await page.reload({waitUntil: 'networkidle2'});
expect(responses.get('one-style.css').fromCache()).toBe(true);
await page.setCacheEnabled(false);
await page.reload({waitUntil: 'networkidle2'});
expect(responses.get('one-style.css').fromCache()).toBe(false);

You can use cdpSession.send()to disable cache:
您可以使用cdpSession.send()禁用缓存：
const client = await page.target().createCDPSession();
await client.send('Network.setCacheDisabled', {
cacheDisabled: true,
});
Alternatively, you can use the more readable page.setCacheEnabled():
或者，您可以使用更具可读性的page.setCacheEnabled()：
await page.setCacheEnabled(false);

If you want session isolation, there is also:
const context = await browser.createIncognitoBrowserContext();
const page = await context.newPage();
which will give you a fresh start on each page.
如果您想要会话隔离，还有：
const context = await browser.createIncognitoBrowserContext();
const page = await context.newPage();
这将使您在每个页面上都有一个新的开始。

Every browser launch starts with clean HTTP cache and without any cookies.
每次浏览器启动都以干净的 HTTP 缓存开始，没有任何 cookie。
let browser = await puppeteer.launch(); // no cache, no cookies!
You may try this. For my cases without cache , i am using this.
你可以试试这个。对于没有缓存的情况，我正在使用它。
