disconnect()
, the browser will continue to process any further response data, but it won't be accessible through the filter. With
close()
, the browser will ignore any response data that hasn't already been passed through to the rendering engine.
You should always call
disconnect()
or
close()
once you don't need to interact with the response any further.
You can't call this function until after the
onstart
event has fired.
filter.disconnect()
None.
None.
BCD tables only load in the browser
This example will prepend "preface text" to the response body. It then disconnects, so the original response body will load normally:
function listener(details) {
let filter = browser.webRequest.filterResponseData(details.requestId);
filter.onstart = event => {
console.log("started");
let encoder = new TextEncoder();
filter.write(encoder.encode("preface text"));
filter.disconnect();
}
}
browser.webRequest.onBeforeRequest.addListener(
listener,
{urls: ["https://example.org/"], types: ["main_frame"]},
["blocking"]
);
