python - 使用粘贴服务器运行时，Bottle GET 请求被某些字符串破坏

Question

我有一个与此类似的问题: Python bottle: UTF8 path string invalid when using app.mount()

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

Critical error while processing request: /languages/Inglês

我尝试了上面链接中提到的修复，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

使用 server='paste' 运行会导致崩溃，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 第 844 行):

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 计算机上使用 Python 3.6.2、Bottle v0.12.13 和 Paste 2.0.3。这是怎么回事？这是 Bottle 或浆糊的问题吗？

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

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