如何在 puppeteer 中获取重定向状态？

Question

我正在尝试使用 puppeteer 编写 Jest 测试

describe('Downloads', () => {
    it(`should refirect to download page for ios`, async () => {
        await page.setUserAgent('exotic');
        let response = await page.goto(`http://localhost:8888/downloads`, {waitUntil: "networkidle0"});
        let url = page.url();
        expect(response.status()).toBe(303);
        expect(url).toBe(`http://localhost:8888/downloads/ios`);
    });
});

但响应状态是200因为goto返回响应http://localhost:8888/downloads/ios

如何获取重定向状态码？

Answer 1

您可以request.redirectChain()为此使用。它返回一个包含所有请求的数组。然后您可以像这样访问第一个请求（和响应）：

const response = await page.goto('...');

const chain = response.request().redirectChain();
const redirectRequest = chain[0];
const redirectResponse = await redirectRequest.response();

expect(redirectResponse.status()).toBe(303);
expect(redirectResponse.url()).toBe('...');
