如何排查"Object of type BufferedReader is not JSON serializable"？

Question

我在POST请求中将表单数据和图像发送到我的后端：

data = {
'username': self.ids['username'].text,
'email': self.email_field.text,
'password': self.ids['password'].text,
'data': json.dumps({
'first_photo': open(f'{self.selfies_path}/first.png', 'rb'),
'second_photo': open(f'{self.selfies_path}/second.png', 'rb'),
'third_photo': open(f'{self.selfies_path}/third.png', 'rb')
})
}
response = requests.post('http://5.10.203.170/auth/register', files=data)

以上抛出python : TypeError: Object of type BufferedReader is not JSON serializable

我怎样才能让它工作？

Answer 1

您可以将文件更改为base64

Answer 2

我选择了：

data = {
'first_photo': open(f'{self.selfies_path}/first.png', 'rb'),
'second_photo': open(f'{self.selfies_path}/second.png', 'rb'),
'third_photo': open(f'{self.selfies_path}/third.png', 'rb'),
'data': json.dumps({
'username': self.ids['username'].text,
'email': self.email_field.text,
'password': self.ids['password'].text
})
}
response = requests.post('http://5.10.203.170/auth/register', files=data)

Answer 3

将字节转换为base64并在您的网站代码中解密
