How to serve file in webpy?

阅读更多关于 How to serve file in webpy?

问题 I am using webpy framefork. I want to serve static file on one of requests. Is there special method in webpy framework or I just have to read and return that file? 回答1: If you are running the dev server (without apache): Create a directory (also known as a folder) called static in the location of the script that runs the web.py server. Then place the static files you wish to serve in the static folder. For example, the URL http://localhost/static/logo.png will send the image ./static/logo.png

PyPI使用国内源通过几次 pip 的使用，对于默认的 pip 源的速度实在无法忍受，于是便搜集了一些国内的pip源，如下：阿里云 http://mirrors.aliyun.com/pypi/simple/ 中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 豆瓣(douban) http://pypi.douban.com/simple/ 清华大学 https://pypi.tuna.tsinghua.edu.cn/simple/ 中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/ 使用方法很简单，直接 -i 加 url 即可！如下： pip install web.py -i http: // pypi.douban.com/simple 来源： oschina 链接： https://my.oschina.net/u/4295888/blog/3340379

问题 First of all, sorry if the linguo is not 100% correct or something does not make 100% of sense, I am quite new into web aplication development and posting on stack overflow in general. I have a web.py application and need to test its functionalities with pytest and generate a code coverage report with pytest-cov . I get the tests to work and assert on the responses, but when I generate the code report, all the lines of code inside the methods are uncovered and therefore get a really low test

问题 I realise this question has been asked before, however this case is slightly different. I want to run a python imageboard (using web.py), that will allow users to generate new images by submitting code. The code will be of the form of a single function that takes the x,y coordinates of a pixel and returns the r,g,b values, eg: def simpleGradient(xrel,yrel): r = xrel*256 g = yrel*256 b = 0 return [r,g,b] Only a very small syntax is required, and it doesn't necessarily have to be python.
