试图在python中使用Mako模板来呈现json数据

Question

我不了解在python中使用Mako模板的文档。 我有一个python文件，并且有以下代码：

import json, requests, urllib2
from mako.template import Template
from mako.lookup import TemplateLookup
from pylons.templating import render_mako as render

url="www.data&format=json"
response = urllib2.urlopen(url)
data = json.load(response)
return (Template("hello Luisito! Here is the data: ${data}!").render(json_data=data))

有人可以为我提供有关如何使用mako模板将此json数据呈现到网页中的更多详细信息吗？ 我需要模板的另一个文件吗？ 如果是这样，怎么办？

Answer 1

您需要为json数据添加一个变量：

url="www.data&format=json"
response = urllib2.urlopen(url)
data = json.load(response)   
from mako.template import Template
print(Template("hello Luisito! Here is the data: ${json_data}!").render(json_data=data))

from mako.template import Template
from mako.lookup import TemplateLookup
from mako import exceptions
