webpy 跑不起来静态文件，为何?

结构是
init_sqlite.py
models.py
.

.
static

• xxx.png
• xxx.css
• xxx.js

根目录static下js都能访问，png和css访问不了报上面的错误，html也加载不成功，服务器500

[the5fire]

我试了下你的代码，mac上可以运行。你js可以访问到，css也应该可以。你注意模板位置

[vixiaoan]

我自己的程序，在ubuntu下运行没有问题，在win8下运行碰到同样的问题，把web\wsgiserver__init__.py
的2056-2059行屏蔽掉就好了。不知道会不会造成其他问题

    for k, v in headers:
        #if not isinstance(k, str):
        #    raise TypeError("WSGI response header key %r is not a byte string." % k)
        #if not isinstance(v, str):
        #    raise TypeError("WSGI response header value %r is not a byte string." % v)
        if k.lower() == 'content-length':
            self.remaining_bytes_out = int(v)
    self.req.outheaders.extend(headers)
    return self.write

[the5fire]

@vixiaoan 你把k和v print出来看看，在win上这俩不是str？
