运行粘贴服务器时 Bottle GET 请求被某些字符串破坏

Question

我遇到了与此类似的问题： Python bottle: UTF8 path string invalid when using app.mount()

当我尝试获取 /languages/Inglês 时，我收到以下错误（注意重音“ê”）。当传递 [az] 字符串时它工作正常。

Critical error while processing request: /languages/Inglês

我尝试了上面 link 中提到的修复，但没有成功。

工作示例:

from bottle import route, run, debug

@route('/languages/<name>')
def hello(name):
    return name

if __name__ == '__main__':
    debug(False)
    #run(reloader=False, port = 8080) # works
    run(server='paste', port = 8080)  # fails

运行 server='paste' 导致崩溃，但使用 Bottle 服务器运行正常。问题似乎发生在 bottle._handle() 方法中，其中抛出 UnicodeError（bottle.py 行 844）：

def _handle(self, environ):
        path = environ['bottle.raw_path'] = environ['PATH_INFO']
        if py3k:
            try:
                environ['PATH_INFO'] = path.encode('latin1').decode('utf8')
            except UnicodeError:
                return HTTPError(400, 'Invalid path string. Expected UTF-8')

我在 Windows 10 机器上使用 Python 3.6.2、Bottle v0.12.13 和 Paste 2.0.3。这是怎么回事？是 Bottle 还是 Paste 的问题？

注意：我已经通过重构所有代码以使用整数 ID 而不是名称来解决我的问题。但我还是想了解更多这方面的知识。

Answer 1

回答我自己的问题，引用@GrahamDumpleton：

The Paste server is not tolerant of being sent non ASCII characters.

Answer 2

这是瓶子的问题！

为了使用粘贴服务器，您可以更改此设置： """bottle.py"""

environ['PATH_INFO'] = path.encode('latin1').decode('utf8', 'ignore')

至：

environ['PATH_INFO'] = path.encode('utf8').decode('utf8', 'ignore') #utf-8 or else

效果不错。
