Fired when a network request has finished and its details are available to the extension.
The request is given as a
HAR entry object
, which is also given an asynchronous
getContent()
method that gets the response body content.
Note that although your extension can add a listener at any time, it will only start firing after the user has activated the browser's network panel at least once.
browser.devtools.network.onRequestFinished.addListener(listener)
browser.devtools.network.onRequestFinished.removeListener(listener)
browser.devtools.network.onRequestFinished.hasListener(listener)
Events have three functions:
addListener(listener)
Adds a listener to this event.
removeListener(listener)
Stop listening to this event. The
listener
argument is the listener to remove.
hasListener(listener)
校验是否
listener
is registered for this event. Returns
true
if it is listening,
false
否则。
callback
Function that will be called when this event occurs. The function will be passed the following arguments:
request
对象
. An object representing the request. This object is a single
HAR entry
object. It also defines an asynchronous
getContent()
method, which returns a
Promise
that resolves with an array of two elements. The first element is the HTTP response body as a string, while the second element is the
MIME 类型
of the HTTP response also as a string.
BCD tables only load in the browser
Add a listener that logs the server IP address and response body for every network request.
function handleRequestFinished(request) {
console.log("Server IP: ", request.serverIPAddress);
request.getContent().then(([content, mimeType]) => {
console.log("Content: ", content);
console.log("MIME type: ", mimeType);
});
}
browser.devtools.network.onRequestFinished.addListener(handleRequestFinished);
