覆盖 Chrome 存储 API
Override Chrome Storage API
我想覆盖 chrome.storage.local.set
以便在调用 Chrome 存储 API 时记录存储键的值:
var storage_local_set = chrome.storage.local.set;
chrome.storage.local.set = function(key, value) {
console.log(key);
storage_local_set(key);
}
但是当调用 storage_local_set(key)
时我得到 Illegal invocation: Function must be called on an object of type StorageArea
。记录密钥后如何存储数据?
对于chrome.storage.sync.set
,这是我根据给出的解决方案尝试的:
const api = chrome.storage.sync;
const { set } = api;
api.set = function (data, callback) {
console.log(data);
set.apply(api, arguments);
};
但这不是挂钩 API
您需要使用 .call() 或 .apply() 来提供 this
对象:
storage_local_set.apply(this, arguments);
不过,您覆盖中的参数与文档不匹配。如果你想匹配文档,那么这样做:
const api = chrome.storage.local;
const { set } = api;
api.set = function (data, callback) {
console.log(data);
set.apply(api, arguments);
};
如果您想将签名更改为单独的键和值:
const api = chrome.storage.local;
const { set } = api;
api.set = (key, value, callback) => {
console.log(key, value);
set.call(api, {[key]: value}, callback);
};
