如何修复 python3 cgi 和 apache2 中的 UnicodeDecodeError

Question

每次我访问我的 apache2 和 python3 CGI 网页时，它都会抛出这个错误： UnicodeDecodeError：'ascii' 编解码器无法解码位置 0 中的字节 0xef：序号不在范围内（128）

我已经尝试重新安装 apache2 和 python3 并在文件打开语句中指定编码。

这是index.py中的代码：

#! /usr/bin/python3
import cgitb
import cgi
import socket
import codecs
cgitb.enable()
print("Content-Type: text/html")
print("")
form = cgi.FieldStorage()
if "code" not in form:
    print(open("main.html","r+").read())

和main.html中的代码：

Answer 1

HTML 可能是 utf-8，但我的假设是文件本身不是。您是否尝试过 open() 中不是 utf-8 的其他编码？我以前被 'latin-1' 绊倒过。

Answer 2

尝试

print("Content-Type: text/html;charset=utf-8")

仅供参考，如果脚本旨在通过命令行运行，您还应该声明

sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf8')
