Tornado JSON 输出新行每个数据而不是每个字符

Question

我无法相应地输出 json 数据。相反，它输出每个字符换行。代码：

import tornado.web
import tornado.ioloop
import tornado.httpserver
from tornado.escape import json_encode

class Handler(tornado.web.RequestHandler):
    def get(self):
        #Sample Json Data
        jsondata = '{ "name": "DU-001", "lat": "4.901787", "lng": "114.925919"}' \
                   ',{ "name": "DU-002", "lat": "4.901789", "lng": "114.925929"}'

        #Rendering to web file
        self.render("web/index.html", title="Lock-On", mydata=json_encode(jsondata))

来自 HTML 代码：循环遍历 mydata 以输出列表

{% for item in mydata %}
{{ item }} <br />
{% end %}

输出结果示例：

" 
{ 

\ 
" 
n 
a 
m 
e 
\ 
" 
: 

\ 
" 
D 
U 
- 
0 
0 
1 
\ 
"

Answer 1

使您的数据成为字典列表而不是字符串。

jsondata = [{"name": "DU-001", "lat": "4.901787", "lng": "114.925919"},{ "name": "DU-002", "lat": "4.901789", "lng": "114.925929"}]
