如何在UTF-8中编码WSGI输出？

pth*_*lin 4 python wsgi wsgiref python-3.x

我想将HTML页面发送到编码为UTF-8的Web浏览器.但是,以下示例失败:

from wsgiref.simple_server import make_server

def app(environ, start_response):
    output = "<html><body><p>Räksmörgås</p></body></html>".encode('utf-8')
    start_response('200 OK', [
        ('Content-Type', 'text/html'),
        ('Content-Length', str(len(output))),
    ])
    return output

port = 8000
httpd = make_server('', port, app)
print("Serving on", port)
httpd.serve_forever()

这是追溯:

Serving on 8000
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/wsgiref/handlers.py", line 75, in run
    self.finish_response()
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/wsgiref/handlers.py", line 116, in finish_response
    self.write(data)
  File "/Library/Frameworks/Python.framework/Versions/3.1/lib/python3.1/wsgiref/handlers.py", line 202, in write
    "write() argument must be a string or bytes"

如果我删除编码并简单地返回python 3 unicode字符串,wsgiref服务器似乎编码在浏览器在请求标头中指定的任何字符集中.但是我想自己拥有这个控件,因为我怀疑我可以期待所有WSGI服务器都这样做.如何返回UTF-8编码的HTML页面？

谢谢!

您需要将页面作为列表返回:

def app(environ, start_response):
    output = "<html><body><p>Räksmörgås</p></body></html>".encode('utf-8')
    start_response('200 OK', [
        ('Content-Type', 'text/html; charset=utf-8'),
        ('Content-Length', str(len(output)))
    ])

    return [output]

WSGI的设计方式使您可以只yield使用HTML(完整或部分).
