覆盖Chrome Storage API [英] Override Chrome Storage API

问题描述

我想重写 chrome.storage.local.set 以便在调用Chrome Storage API时记录存储密钥的值:

I would like to override chrome.storage.local.set in order to log the value of a storage key when the Chrome Storage API is called:

var storage_local_set = chrome.storage.local.set;
chrome.storage.local.set = function(key, value) {
    console.log(key);
    storage_local_set(key);    
}

但是我得到非法调用:在调用 storage_local_set(key)时，必须在StorageArea类型的对象上调用函数.记录密钥后如何存储数据?

But I get Illegal invocation: Function must be called on an object of type StorageArea when storage_local_set(key) gets called. How can I store the data after logging the key?

对于 chrome.storage.sync.set ，这是我根据给定的解决方案尝试的方法:

For chrome.storage.sync.set this is what I tried based on the solution given:

const api = chrome.storage.sync;
const { set } = api; 
api.set = function (data, callback) {
  console.log(data);
  set.apply(api, arguments);  
};

但这并不钩住API

推荐答案

您需要使用.call()或.apply()提供 this 对象:

You need to use .call() or .apply() to provide this object:

storage_local_set.apply(this, arguments);

您的替代中的参数与文档不匹配.如果要匹配文档，请按以下步骤进行操作:

The parameters in your override don't match the documentation though. If you want to match the documentation then do it like this:

const api = chrome.storage.local;
const { set } = api; 
api.set = function (data, callback) {
  console.log(data);
  set.apply(api, arguments);    
};

如果要更改签名以将键和值分隔开:

And if you want to change the signature to separate key and value:

const api = chrome.storage.local;
const { set } = api; 
api.set = (key, value, callback) => {
  console.log(key, value);
  set.call(api, {[key]: value}, callback);    
};
