Python string argument without an encoding
提问by lonely
Am trying to a run this piece of code, and it keeps giving an error saying "String argument without an encoding"
我正在尝试运行这段代码,它不断给出错误提示“没有编码的字符串参数”
ota_packet = ota_packet.encode('utf-8') + bytearray(content[current_pos:(final_pos)]) + 'bytearray(content[current_pos:(final_pos)])
'.encode('utf-8')
Any help?
有什么帮助吗?

You are passing in a string object to a bytearray()
:
您正在将字符串对象传递给 a bytearray()
:
bytearray(content[current_pos:(final_pos)], 'utf8')
You'll need to supply an encoding argument (second argument) so that it can be encoded to bytes.
您需要提供一个编码参数(第二个参数),以便将其编码为字节。
For example, you could encode it to UTF-8:
例如,您可以将其编码为 UTF-8:
##代码##From the bytearray()
documentation:
The optional sourceparameter can be used to initialize the array in a few different ways:
- If it is a string, you must also give the encoding(and optionally, errors) parameters;
bytearray()
then converts the string to bytes usingstr.encode()
.
可选的source参数可用于以几种不同的方式初始化数组:
- 如果它是一个字符串,你还必须给出编码(和可选的错误)参数;
bytearray()
然后使用 将字符串转换为字节str.encode()
。
