Tyl*_*our 3 python pythonanywhere
我一直在试验PythonAnywhere试图让一些python在Web服务器上工作.我最初从Arvixe切换,因为他们运行2.4并且PythonAnywhere的名字太吸引人了.
我的应用程序包含两个文件:phones.py和phonesearch.py.他们一起应该为电话价格刮取craigslist.
我在2.7本地测试,它运行得很好,生成一个带有表格和所有价格的html页面(celly.html).当我上传它时,它生成html就好了,但拒绝在我的价格列表中添加任何内容([intprices]).
我的怀疑:(a)因为它在本地工作正常,PythonAnywhere不允许它与craigslist通信; 或者(b)因为我这样做就像一个穴居人而不是使用微框架,PythonAnywhere否认我; 或(c)我对自己的错误视而不见,而且我错过了一些明显的错误.
我的Python脚本位于在/ home/tseymour/mysite的和正在生成的HTML 一样 /mysite/static/celly.html.该文件在http://tseymour.pythonanywhere.com/static/celly.html上提供
您会注意到我的所有单元格都填充了"N/A",这意味着它在try:"在SearchPhone.py中引发了一个IndexError.这意味着我的列表正在被填充!
但为什么会这样？!我相信这是因为我是PythonAnywhere n00b.
请指教.
