api - How can I check the total contents of chrome.storage?

Question

In the chrome developer tools you can switch between different contexts in the javascript console and individually query the chrome.storage.local.get() and chrome.storage.sync.get() APIs. Is there a way to view the totality of what is stored there for all of chrome?

Answer 1

如果您查看 API 的源代码

bool StorageGetFunction::RunWithStorage(ValueStore* storage) {
  Value* input = NULL;
  EXTENSION_FUNCTION_VALIDATE(args_->Get(0, &input));

  switch (input->GetType()) {
    case Value::TYPE_NULL:
      return UseReadResult(storage->Get());

    case Value::TYPE_STRING: {
      std::string as_string;
      input->GetAsString(&as_string);
      return UseReadResult(storage->Get(as_string));
    }

    case Value::TYPE_LIST: {
      std::vector<std::string> as_string_list;
      AddAllStringValues(*static_cast<ListValue*>(input), &as_string_list);
      return UseReadResult(storage->Get(as_string_list));
    }

    case Value::TYPE_DICTIONARY: {
      DictionaryValue* as_dict = static_cast<DictionaryValue*>(input);
      ValueStore::ReadResult result = storage->Get(GetKeys(*as_dict));
      if (result->HasError()) {
        return UseReadResult(result.Pass());
      }

      DictionaryValue* with_default_values = as_dict->DeepCopy();
      with_default_values->MergeDictionary(result->settings().get());
      return UseReadResult(
          ValueStore::MakeReadResult(with_default_values));
    }

    default:
      return UseReadResult(
          ValueStore::MakeReadResult(kUnsupportedArgumentType));
  }
}

存储类型用作查询结果的参数。因此，到目前为止，还无法查看所有 chrome 中存储的全部内容，您必须使用两个不同的查询（chrome.storage.local.get()和chrome.storage.sync.get()API）。

你试过这个吗？控制台.log(chrome.storage);
