尝试在 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，我有以下代码：

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))

有人能给我提供一些关于如何使用 mako 模板将这个 json 数据呈现到网页中的更多细节吗？我需要另一个包含模板的文件吗？如果是这样，如何？

Answer 1

你需要为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))
