python API没有提供直接读/写本地存储的方法，但可以使用execute_script来完成。
class LocalStorage:
def __init__(self, driver) :
self.driver = driver
def __len__(self):
return self.driver.execute_script("return window.localStorage.length;")
def items(self) :
return self.driver.execute_script( \
"var ls = window.localStorage, items = {}; " \
"for (var i = 0, k; i < ls.length; ++i) " \
" items[k = ls.key(i)] = ls.getItem(k); " \
"return items; ")
def keys(self) :
return self.driver.execute_script( \
"var ls = window.localStorage, keys = []; " \
"for (var i = 0; i < ls.length; ++i) " \
" keys[i] = ls.key(i); " \
"return keys; ")
def get(self, key):
return self.driver.execute_script("return window.localStorage.getItem(arguments[0]);", key)
def set(self, key, value):
self.driver.execute_script("window.localStorage.setItem(arguments[0], arguments[1]);", key, value)
def has(self, key):
return key in self.keys()
def remove(self, key):
self.driver.execute_script("window.localStorage.removeItem(arguments[0]);", key)
def clear(self):
self.driver.execute_script("window.localStorage.clear();")
def __getitem__(self, key) :
value = self.get(key)
if value is None :
raise KeyError(key)
return value
def __setitem__(self, key, value):
self.set(key, value)
def __contains__(self, key):
return key in self.keys()
def __iter__(self):
return self.items().__iter__()
def __repr__(self):
return self.items().__str__()
用法示例：
# 获取 local storage
storage = LocalStorage(driver)
# 设置一个值 item
storage["mykey"] = 1234
storage.set("mykey2", 5678)
# 获取一个值 item
print(storage["mykey"]) # raises a KeyError if the key is missing
print(storage.get("mykey")) # returns None if the key is missing
# 删除一个值 item
storage.remove("mykey")
# 循环取值 items
for i in storage:
print(i, storage[i])
# 清空 items
storage.clear()
补充细节，循环赋值先把class对象转换为字典类型
# 循环赋值 items
storage = LocalStorage(driver)
print(storage)
d =dict(storage) #先把class对象转换为字典类型
print(d)
storage.clear()
driver.refresh()
storage.clear()
#循环赋值
for i in d:
print(i, d[i])
storage.set(i, d[i])
driver.refresh()
