javascript - Safari IOS 10 上的错误 : The quota has been exceeded.

Question

我在 iPhone 的 safari 上遇到这个错误，在执行 localStorage.setItem('user',some string here) 时:

Error: The quota has been exceeded.
setItem@[native code]

不是私有(private)模式!还有哪些情况会导致 localStorage 不工作？

我创建了这个类来帮助绕过隐私浏览。但是，当您刷新浏览器时，存储空间将被消耗殆尽。

const data = {};
let hasLocalStorage = false;

if (localStorage) {
  try {
    const x = 'storageTest';
    localStorage.setItem(x, x);
    localStorage.removeItem(x);
    hasLocalStorage = true;
  } catch (e) {
    hasLocalStorage = false;
  }
}

class StorageUtilities {
  setItem(key, value) {
    if (hasLocalStorage) {
      localStorage.setItem(key, value);
    } else {
      data[key] = value;
    }
  }

  getItem(key) {
    if (hasLocalStorage) {
      return localStorage.getItem(key);
    }
    return data[key];
  }

  removeItem(key) {
    if (hasLocalStorage) {
      localStorage.removeItem(key);
    } else {
      data[key] = null;
    }
  }
}

const storageUtilities = new StorageUtilities();

export default storageUtilities;
