执行interface_AES_test.py的时候result = r.json()会报错 about guest HOT 3 OPEN

安装pycryptodomex后，更改为from Cryptodome.Cipher import AES，再次运行后报错：
ERROR: test_aes_interface (main.AESTest)
test aes interface

修改了两行代码：
self.app_key = str.encode('W7v4D60fds2Cmk2U')
ciphertext = cryptor.encrypt(str.encode(self.pad(src)))

再次运行报错和未更改库之前一样：
Traceback (most recent call last):
File "G:/PycharmProjects/Django/guest-master/tests/interface_AES_test.py", line 46, in test_aes_interface
result = r.json()

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 2 column 1 (char 1)

望看到后可以帮忙解答一下，代码是按照书和GitHub里对比过的，未改动。

这书感觉坑贼多
