使用浆糊s运行时，瓶子获取请求被某些字符串破坏

Question

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

当我试图得到/languages/Inglês时，我收到了下面的错误（注意重音“è”）。当传递[az]字符串时，它工作得很好。在

Critical error while processing request: /languages/Inglês

我尝试了上述链接中提到的修复，但没有成功。在

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，但使用瓶子服务器运行正常。问题似乎发生在bottle._handle()方法中，其中抛出了UnicodeError（bottle.py第844行）：

^{pr2}$

我在Windows10机器上使用Python 3.6.2、Bottle v0.12.13和{}。发生什么事？这是瓶子还是浆糊的问题？在

注意：我已经通过重构所有代码来解决我的问题，使用整数id而不是名称。但我还是想了解更多。在

在回答我自己的问题时，引用@GrahamDumpleton的话：

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