Can Puppeteer monitor network requests for a website, specifically those involving redirects, when working with Google Maps?
Puppeteer is fully capable of monitoring network requests that include redirects.
How to Solve This?
During automated testing with Puppeteer, you might need to perform actions on a page that has undergone multiple redirects. You can use the page.on('response', ...) event to listen for responses and check the response.status() to identify redirects. HTTP status codes in the 300-399 range indicate that a redirect has occurred.
Code Example:
javascript
page.on('response',response =>{
const status = response.status();
if(status >= 300 && status <= 399){
console.log(`Redirect occurred: from ${response.url()} to ${response.headers()['location']}`);
}
});
Additionally, Consider This Method:
The waitForNavigation() Method
Using the waitForNavigation() Method
method to wait for page loading to complete—waiting until the entire page is fully loaded before proceeding—can effectively prevent issues that arise from performing actions before the page is ready. After triggering an action that causes navigation (like a click), use waitForNavigation() Method
again to wait for the new page to load.
If multiple redirects exist, the navigation will resolve with the response of the last redirect. The navigation will resolve to null if the navigation is to a different anchor or due to History API usage.
javascript
await page.goto(url)
await page.waitForNavigation()
await page.click('#login-button')
await page.waitForNavigation()
await page.waitForSelector('#some-element')
