Comment obtenir le localStorage avec Python et Selenium WebDriver

L'API python n'est pas un moyen pour directement lire/écrire les locaux de stockage, mais il peut être fait avec execute_script.

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__()

Exemple d'utilisation:

# get the local storage
storage = LocalStorage(driver)
# set an item
storage["mykey"] = 1234
storage.set("mykey2", 5678)
# get an item
print(storage["mykey"])      # raises a KeyError if the key is missing
print(storage.get("mykey"))  # returns None if the key is missing
# delete an item
storage.remove("mykey")
# iterate items
for key, value in storage.items():
print("%s: %s" % (key, value))
# delete items
storage.clear()

Essayer:

driver.execute_script("window.localStorage.setItem('key','value');");
driver.execute_script("window.localStorage.getItem('key');");
