[英]How to append values when the key is a hashed string in dictionary?
The type of encrypted_index is dictionary, and now I want to append values in it. encrypted_index 的类型是字典,现在我想在其中输入 append 值。
def update(self, keyword, text):
encrypted_index=dict()
with open('encrypted_index', "rb") as f:
encrypted_index = pickle.load(f)
with open('keys', "rb") as f:
keys = pickle.load(f)
#initial keys and iv
keyword_sk = keys[0]
doc_sk = keys[1]
iv = keys[2]
#encrypt the text and keyword
enc_text = self.aesEncrypt(doc_sk, text, iv)
encrypted_search_keyword = self.encrypt_keyword(keyword_sk, bytes(keyword,'utf-8'))
for enc_keyword in encrypted_index:
if(encrypted_search_keyword == enc_keyword):
encrypted_index[enc_keyword].append(enc_text)
print(encrypted_index)
File "c:/Users/76998/Downloads/SSE/Client.py", line 85, in update
encrypted_index[enc_keyword].append(enc_text)
AttributeError: 'bytes' object has no attribute 'append'
The key of the dictionary is hashed by using hmac, so I can't append values.字典的键是使用 hmac 散列的,所以我不能 append 值。 Is it possible to append values when the key is hashed?
当密钥被散列时,是否可以 append 值?
encrypted_index looks like that encrypted_index 看起来像这样
{b'E\x9e\x06\x8f\xca\xb6\x8b\x95\xb0.5\xc2\xc4\xce\xd9\xe1\xefB\xcc\x0b\xe7Y\xec\xbc\x1b\x04\xde\x15\x06+R\xbf': b'>\xb6}\x0e\xc9[\x17VS\xa3h\x9aC\xb9?\x0c\xbap\x99\xc4`\xed\xdb0*\x17\x81\x90H^\xc6S'}
append()
is for adding an element to a list. append()
用于将元素添加到列表中。 Since the value is a string, you need to concatenate with the +
operator.由于该值是一个字符串,因此您需要与
+
运算符连接。
encrypted_index[enc_keyword] += enc_text
There's also no need for the for
loop.也不需要
for
循环。 Just write:写吧:
if enc_keyword in encrypted_index:
encrypted_index[enc_keyword] += enc_text
print(encrypted_index)
