from bottle import error
@error(404)
def error404(error):
    return ‘Nothing here, sorry‘

上述代碼，是對404的定義，這裏註意，有一個HTTPError，

HTTPError uses a predefined HTML template to build the body of the response. Instead of using HTTPError you can use response with the appropriate status code and body.

import json
 
from bottle import run, route, response

@route(‘/text‘)
def get_text():
    response.status = 400
    return ‘Object already exists with that name‘

@route(‘/json‘)
def get_json():
    response.status = 400
    response.content_type = ‘application/json‘
    return json.dumps({‘error‘: ‘Object already exists with that name
 
‘})

# Start bottle server.
run(host=‘0.0.0.0‘, port=8070, debug=True)

使用bottle進行web開發（4）：HTTPError
