webRequest.getSecurityInfo()

Use this function to get detailed information about the TLS connection associated with a particular request.

You pass this function the requestId for the request in question, and some optional extra parameters. It returns a Promise which will resolve to a SecurityInfo 对象。

You can only call this function from inside the webRequest.onHeadersReceived listener. The requestId 可以找到在 details object which is passed into the listener.

You must also pass the "blocking" option to webRequest.onHeadersReceived.addListener() . So to use this API you must have the "webRequestBlocking" API permission , as well as the normal permissions needed for using webRequest listeners (the "webRequest" permission and the host permission for the host).

参数

requestId

string . ID of the request for which you want security info. You can get this from the details object that is passed into any webRequest event listeners.

选项

对象 . An object which may contain any of the following properties, all optional:

certificateChain 可选

boolean 。若 true SecurityInfo object returned will include the entire certificate chain up to and including the trust root. If false , it will include only the server certificate. Defaults to false .

rawDER 可选

范例

This example listens for all HTTPS requests to "mozilla.org" or its subdomains, and logs the subject name in the server certificate:

async function logSubject(details) {
  try {
    let securityInfo = await browser.webRequest.getSecurityInfo(details.requestId, {});
    console.log(details.url);
    if (securityInfo.state === "secure" || securityInfo.state === "weak") {
      console.log(securityInfo.certificates[0].subject);
    }
  }
  catch(error) {
    console.error(error);
  }
}
browser.webRequest.onHeadersReceived.addListener(logSubject,
  {urls: ["https://*.mozilla.org/*"]},
  ["blocking"]
);

						

This example listens for all HTTPS requests to "mozilla.org" or its subdomains, and logs the name in the trusted root certificate:

async function logRoot(details) {
  try {
    let securityInfo = await browser.webRequest.getSecurityInfo(
      details.requestId,
      {"certificateChain": true}
    );
    console.log(details.url);
    if (securityInfo.state === "secure" || securityInfo.state === "weak") {
      console.log(securityInfo.certificates[securityInfo.certificates.length - 1].issuer);
    }
  }
  catch(error) {
    console.error(error);
  }
}
browser.webRequest.onHeadersReceived.addListener(logRoot,
  {urls: ["https://*.mozilla.org/*"]},
  ["blocking"]
);
