Unicode解码错误：'charmap'编解码器无法解码位置 8024 中的字节0x9d：<undefined>将输出重定向到磁盘时字符映射到

Question

在Windows 10上，我使用httpie来检索数据。当在屏幕上显示时，它工作得很好，但一旦我将输出管道传输到磁盘，我就会得到http:error:UnicodeDecodeError:"charmap"编解码器无法解码位置8024中的字节0x9d：字符映射到<undefined>

写入磁盘时有没有办法更改编码？

以下是完整的调试输出：

Answer 1

HTTPie从系统的stdout配置中获取编码。您已经为Windows 1252配置了它，并试图用它的功能(可能是utf8(写下数据。

虽然HTTPie没有提供单独配置编写器输出编码的选项，但您可以通过PYTHONIOENCODING环境变量设置输出的默认值。试试这个

PYTHONIOENCODING=utf-8 http --debug --print=Bb --pretty=all --session=C:UsersPETERK~1AppDataLocalTemp/access.json http://localhost:8080/nexus/extract/path  filePath=c:/TestFiles/100Mb.pdf > foo

事实上，我对Windows并不太熟悉——如果这不起作用，请在运行HTTPie:之前设置运行这个

setx PYTHONIOENCODING "utf-8"

请注意，这将覆盖此命令行会话的所有其他Python脚本的编码。
