Methods for returning static files and JSON objects in the bottle framework of Python

The code is as follows:

#-*-Coding:utf-8-*-#!/usr/bin/python# filename:todo.py# codedtime:2014-8-28 20:50:44import sqlite3import bottle
  
    @bottle. Route ('/help3 ') def help ():  return Bottle.static_file (' help.html ', root= '. ') #静态文件 @bottle. Route ('/json : json#[0-9]+# ') def Show_json (JSON):  conn = sqlite3.connect (' todo.db ')  C = conn.cursor ()  C.execute (" Select Task from Todo WHERE id like? ", (JSON))  result = C.fetchall ()  c.close ()  If not result:    return {' Ta ' SK ': ' This item number does not exist! '}  Else:    return {' Task ': result[0]} #返回Json对象bottle. Debug (True) bottle.run (host= ' 127.0.0.1 ', port=8080, Reloader = True)
  

The first route @bottle.route ('/HELP3 ') returns a static question, entered in the browser: HTTP://127.0.0.1:8080/HELP3

The results are as follows:

One of the root= '. ') or root= './') indicates that in the current directory of the program, you can also know other paths such as: root= '/path/to/file '

The second route @bottle.route ('/json:json#[0-9]+# ') returns a JSON object, entered in the browser: http://127.0.0.1:8080/json4

The results are as follows:

Web programs will inevitably encounter errors in access failures, so how to catch these errors, bottle can use the routing mechanism to catch errors, the following captures 403, 404:

@error (403) def mistake403 (code):  return ' The parameter you passed have the wrong format! ' @error (404) def mistake404 (code):  return ' Sorry, this page does not exist! '

Other error handling such as the FA Bubble System!
