標(biāo)題: 再求助,webpy的代碼在wsgi中改如何修改? [打印本頁(yè)]

標(biāo)題: 再求助,webpy的代碼在wsgi中改如何修改?
webpy初學(xué)，有問題不明白，請(qǐng)教各位牛人，感激中....

在使用python code.py調(diào)試環(huán)境中一切正常的webpy應(yīng)用，換到apache+wsgi環(huán)境中就出錯(cuò)，
該如何修改?

code.py代碼如下，編碼格式為utf-8 ,是一個(gè)典型的使用模板的hello world.

#!/usr/bin/python
# -*- coding: utf-8 -*-

import web

urls = (
      '/(.*)', 'hello'
)

app = web.application(urls, globals())

class hello:
      def GET(self, name):
            render = web.template.render('tpl/')
            return render.hello(name)

if __name__ == "__main__":
      app.run()

#application = web.application(urls, globals()).wsgifunc()

模板的 hello.html

$def with (name)
$if name:
你好阿, $name.
$else:
你好,世界.

用 python  code.py 啟動(dòng)調(diào)試web服務(wù)，一切正常。換到apache+wsgi環(huán)境中就報(bào)錯(cuò)，加下最下面一行
application = web.application(urls, globals()).wsgifunc()
也不行，出現(xiàn)錯(cuò)誤提示：internal server error。

安裝配置好的apache,運(yùn)行下面的code.py正常，

apache的配置：

LoadModule wsgi_module modules/mod_wsgi.so

WSGIScriptAlias  /          "D:/wwwroot/webpy/code.py"
Alias          /static    "D:/wwwroot/webpy/static/"
AddType       text/html .py

<Directory "D:/wwwroot/webpy">
   Order deny,allow
   Allow from all
</Directory>

code.py重新寫過，hello word,沒有使用模板。

#!/usr/bin/python
# -*- coding: utf-8 -*-
import web

urls = (
   '/hello', 'hello',
      )

app = web.application(urls, globals())

class hello:
   def GET(self):
      return 'Hello word!'

application = web.application(urls, globals()).wsgifunc()

在瀏覽中輸入，http://127.0.0.1/hello apche和wsgi提供的服務(wù)一切正常。

請(qǐng)問各位老師，webpy+wsgi中使用模板的話，該怎么寫最后的語(yǔ)句才對(duì)呢？
感激不盡！

謝謝thinkc的提醒，原因已經(jīng)找到。
apache錯(cuò)誤日志如下:

意思是模板文件沒有找到，修改了code.py如下，問題基本解決。

#!/usr/bin/python
# -*- coding: utf-8 -*-

import web

urls = (
      '/(.*)', 'hello'
)

app = web.application(urls, globals())

class hello:
      def GET(self, name):
            render = web.template.render('D:/wwwroot/webpy/templates/') #使用絕對(duì)路徑，相對(duì)路徑該怎么用呢？
            return render.hello(name)

if __name__ == "__main__":
      app.run()

application = web.application(urls, globals()).wsgifunc()

下一步切換到linux環(huán)境下一試。

再次感謝thinkc，問題圓滿解決，linux下的實(shí)驗(yàn)也很成功。
