## **ubinascii** – 二进制/ ASCII转换
|
|
|
|
|
|
|
|
|
|
|
|
`ubinascii` 模块包含许多在二进制和各种 ascii 编码的二进制表示之间转换的方法。
|
|
|
|
|
|
|
|
|
|
|
|
### 函数
|
|
|
|
|
|
|
|
|
|
|
|
#### **ubinascii.hexlify**(data[, sep])
|
|
|
|
|
|
将字符串转换为十六进制表示的字符串。
|
|
|
|
|
|
|
|
|
|
|
|
示例：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
>>> ubinascii.hexlify('hello RT-Thread')
|
|
|
|
|
|
b'68656c6c6f2052542d546872656164'
|
|
|
|
|
|
>>> ubinascii.hexlify('summer')
|
|
|
|
|
|
b'73756d6d6572'
|
|
|
|
|
|
```
|
|
|
|
|
|
如果指定了第二个参数sep，它将用于分隔两个十六进制数。
|
|
|
|
|
|
|
|
|
|
|
|
示例：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
如果指定了第二个参数sep，它将用于分隔两个十六进制数。
|
|
|
|
|
|
示例：
|
|
|
|
|
|
>>> ubinascii.hexlify('hello RT-Thread'," ")
|
|
|
|
|
|
b'68 65 6c 6c 6f 20 52 54 2d 54 68 72 65 61 64'
|
|
|
|
|
|
>>> ubinascii.hexlify('hello RT-Thread',",")
|
|
|
|
|
|
b'68,65,6c,6c,6f,20,52,54,2d,54,68,72,65,61,64'
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
#### **ubinascii.unhexlify**(data)
|
|
|
|
|
|
转换十六进制字符串为二进制字符串，功能和 hexlify 相反。
|
|
|
|
|
|
|
|
|
|
|
|
示例：
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
>>> ubinascii.unhexlify('73756d6d6572')
|
|
|
|
|
|
b'summer'
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
#### **ubinascii.a2b_base64**(data)
|
|
|
|
|
|
Base64编码的数据转换为二进制表示。返回字节串。
|
|
|
|
|
|
|
|
|
|
|
|
#### **ubinascii.b2a_base64**(data)
|
|
|
|
|
|
编码base64格式的二进制数据。返回的字符串。
