避免'字符参数不在范围内'python3解码

Question

我正在尝试解码对requests.get()特定 url 的调用内容。导致问题的 url 在代码的多次运行中并不总是相同的，但是产生问题的请求内容的部分具有三个反斜杠，这在使用unicode-escape.

作为在 Python 3.6.1 中运行的代码的简化版本

r=b'\xf0\\\xebI'

r.decode('unicode-escape').strip().replace('{','\n')

产生以下错误：

OverflowError: character argument not in range(0x110000)

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

OverflowError: decoding with 'unicode-escape' codec failed (OverflowError: character argument not in range(0x110000))

我想跳过产生错误的部分。我是一个新手 python 程序员，所以非常感谢任何帮助。

Answer 2

数据似乎被编码为 latin-1 *，因此最简单的解决方案是解码然后删除反斜杠。>>> r=b'\xf0\\\xebI'>>> r.decode('latin-1').replace('\\', '')'ðëI'*我猜是 latin-1（也称为 ISO-8859-1）——响应的内容类型标头应该指定使用的编码，它可能是其他 ISO-8859-* 编码之一。
