The event life cycle for successful requests is illustrated here, followed by event definitions: The web request API guarantees that for each request either onCompleted or onErrorOccurred is fired as the final event with one exception: If a request is redirected to a data:// URL, onBeforeRedirect is the last reported event. True for Proxy-Authenticate, false for WWW-Authenticate. You must not parse and act based upon its content. If your extension is used on a hostile network, an network attacker (aka a "man-in-the-middle") could modify the response and, potentially, attack your extension. XMLHttpRequest . Instead, prefer HTTPS whenever possible. This may occur after a TCP connection is made to the server, but before any HTTP data is sent. Might be evaluating an evil script!

If you need to deceive the CORS protocol, you also need to specify 'extraHeaders' for the response modifications. Note: Specifying 'extraHeaders' in opt_extraInfoSpec may have a negative impact on performance, hence it should only be used when really necessary.

Also synchronous XMLHttpRequests from your extension are hidden from blocking event handlers in order to prevent deadlocks. Cross-origin permission values can be fully qualified host names, like these: Or they can be match patterns, like these: A match pattern of "https://*/" allows HTTPS access to all reachable domains. Also note that access is granted both by host and by scheme. If you modify the default Content Security Policy for apps or extensions by adding a content_security_policy attribute to your manifest, you'll need to ensure that any hosts to which you'd like to connect are allowed.

On the other hand, response header modifications do not work to deceive CORS checks. To construct an XHR object you use new XMLHttpRequest();.. getXMLHttpRequest is not a standard function.. Ackermann Function without Recursion or Stack. Most people making HTTP requests from node use a third party library with a friendlier API. One (insecure) approach would be to have the content script specify the exact resource to be fetched by the background page. Therefore make sure that you're executing the jQuery code only after jQuery library file has finished loading. If this argument is true or not specified, the XMLHttpRequest is processed asynchronously, otherwise the process is handled synchronously. The three arguments to the web request API's addListener() have the following definitions: Here's an example of listening for the onBeforeRequest event: Each addListener() call takes a mandatory callback function as the first parameter. (Content scripts have been subject to CORB since Chrome 73 and CORS since Chrome 83.)

Only one extension is allowed to redirect a request or modify a header at a time. For example, if an extension contains a JSON configuration file called config.json, in a config_resources folder, the extension can retrieve the file's contents like this: var xhr = new XMLHttpRequest(); To do the request, we need 3 steps: Create XMLHttpRequest: let xhr = new XMLHttpRequest(); The constructor has no arguments. If more than one extension attempts to modify the request, the most recently installed extension wins and all others are ignored. Not sure what I'm missing here. Don't call it often.

Specifically, avoid using dangerous APIs such as the below: Instead, prefer safer APIs that do not run scripts: When performing cross-origin requests on behalf of a content script, be careful to guard against malicious web pages that might try to impersonate a content script. Additionally, be especially careful of resources retrieved via HTTP. Starting from Chrome 72, an extension will be able to intercept a request only if it has host permissions to both the requested URL and the request initiator. For example, if an extension contains a JSON configuration file called config.json, in a config_resources folder, the extension can retrieve the file's contents like this: If the extension attempts to use a security origin other than itself, say https://www.google.com, the browser disallows it unless the extension has requested the appropriate cross-origin permissions. A Chrome extension is a system made of different modules (or components), where each module provides different interaction types with the browser and user.
