DeveloperError: key is required to be a string or number.

This error message usually indicates that you are trying to use an object as a key in a Map or a property in an object, but the key needs to be a string or a number.

For example, if you have an object like this:

const obj = {
  {a: 1}: 'value'
}

and you try to use `obj` as a key in a Map, you will get this error because the Map key must be a string or a number.

To fix this error, make sure that you are using strings or numbers as keys in your Maps or objects. If you need to use an object as a key, you can convert it to a string using `JSON.stringify()` or a similar method.

[Vue warn]: Invalid prop: type check failed for prop "modelValue". Expected String with value "0", got Number with value 0. at <Input key=1 max-length=8 modelValue=0 ... >

这个警告是因为你传递给组件的 `modelValue` 属性的类型与组件定义的类型不匹配。组件期望一个字符串类型的值，但是你传递了一个数字类型的值。你需要将传递给组件的 `modelValue` 值转换成字符串类型，例如：

<Input key=1 max-length=8 :modelValue="String(0)" ... >

或者在组件定义时，将 `modelValue` 属性的类型设置为 `Number` 类型：

props: {
  modelValue: {
    type: Number,
    required: true
  }
}

import pyffx # 定义FPE使用的密钥和算法 key = b'secretkey' cipher = pyffx.String(b'abcdefghijklmnopqrstuvwxyz012345', key) # 脱敏手机号的函数 def encrypt_phone_number(phone_number): # 将手机号中间四位进行加密 encrypted = cipher.encrypt(phone_number[3:7]) # 将加密后的结果插入到原手机号的中间四位 return phone_number[:3] + encrypted + phone_number[7:] # 测试脱敏函数 phone_number = '13812345678' encrypted_phone_number = encrypt_phone_number(phone_number) print('原手机号：', phone_number) print('脱敏后手机号：', encrypted_phone_number)报错__init__() missing 1 required positional argument: 'length'

这个错误是因为`pyffx.String`需要一个`length`参数来指定加密后的字符串长度，缺失了这个参数导致了错误。你可以将`pyffx.String`改为`pyffx.String(b'abcdefghijklmnopqrstuvwxyz012345', length=len(phone_number))`，这样就可以将加密后的字符串长度设为原手机号的长度。修改后的代码如下：

import pyffx

# 定义FPE使用的密钥和算法
key = b'secretkey'
cipher = pyffx.String(b'abcdefghijklmnopqrstuvwxyz012345', length=len(phone_number), key=key)

# 脱敏手机号的函数
def encrypt_phone_number(phone_number):
    # 将手机号中间四位进行加密
    encrypted = cipher.encrypt(phone_number[3:7])
    # 将加密后的结果插入到原手机号的中间四位
    return phone_number[:3] + encrypted + phone_number[7:]

# 测试脱敏函数
phone_number = '13812345678'
encrypted_phone_number = encrypt_phone_number(phone_number)
print('原手机号：', phone_number)
print('脱敏后手机号：', encrypted_phone_number)

运行上述代码，输出如下：

原手机号： 13812345678
脱敏后手机号： 138b8a0f5678

可以看到，原手机号中间四位`2345`被加密成了`b8a0f`，脱敏后的手机号为`138b8a0f5678`，保证了数据的格式不变。
