问题描述
<！DOCTYPE html>
< html lang =en>
< head>
< title> {％block title％} {％endblock title％}< / title>
< link href =http://netdna.bootstrapcdn.com/bootswatch/2.3.2/united/bootstrap.min.css =stylesheet>
< link href =http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-response.min.css =stylesheet>
< script src =http://code.jquery.com/jquery-1.9.1.min.js>< / script>
< script src =http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js>< / script>
< / head>
< body>
< div id =main>
< div class =utility-nav navbar navbar-fixed-top>
< div class =navbar-inner>
< div class =container>
{＃Navbar走到这里。 ＃}
< / div>
< / div>
< / div>
< div class =content container>
{％block main％} {％endblock main％}
< / div>
< / div>
< / body>
< / html>
和
{％extends'base.html'％}
{％block title％} Page Title {％endblock title％}
{％block main％}
< h2>这是一个子模板。< / h2>
{％endblock main％}
然后我有以下功能
pre $
from flask.ext.restful import从app.business.login导入资源，请求，重新分配
导入从应用程序登录
.business.appointments从app.models.models导入约会
导入用户，地址，约会$ b $从瓶子导入render_template
class AppointmentController（资源）：
def __init __（self）：
pass
def get（self）：
return render_template（'index.html'）
所以当我启动服务器并说 http://0.0.0.0:5000/appointment 我得到
<！DOCTYPE html> \\\
< html lang = \en \> \\\
< head> \\\
< title>页面标题< / title> \\\
\\\
< link href = \http://netdna.bootstrapcdn.com/bootswatch/2.3.2/united/bootstrap.min.css\相对= \stylesheet\\ \\> \\\
< link href = \http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/bootstrap-response.min.css\rel = \ stylesheet \> \\\
< script src = \http://code.jquery.com/jquery-1.9.1.min.js\>< / script> \\\
< ; script src = \http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js\>< / script> \\\
< / head> \\ \\ n< body> \\\
< div id = \main \> \\\
< div class = \utility-nav navbar navbar-fixed-top \> \\\
< div class = \navbar-inner \> \\\
< div class = \container \> \\\
\\\
< / div> \\\
< div> \\\
< / div> \\\
< div class = \content container \> \\\
\\\
\t< h2>这是一个子模板< / h2> ; \\\
\\\
< / div> \\\
< / div> \\\
< / body> \\\
< / html>
这意味着模板正在工作，但浏览器将响应视为String而不是HTML。我究竟做错了什么。
解决方案
我相应地修改了get。设置内容类型的技巧。
pre $ class AppointmentController（Resource）：
def __init __（self）：
$ pass b $ b def get（self）：
headers = {'Content-Type'：'text / html'}
return make_response（render_template（'index.html'），200，头文件）
I am new to Python and Flask. I have a templates folder in the the root of my application whic has two file.
<!DOCTYPE html>
<html lang="en">
<head>
<title>{% block title %}{% endblock title %}</title>
<link href="http://netdna.bootstrapcdn.com/bootswatch/2.3.2/united/bootstrap.min.css" rel="stylesheet">
<link href="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/ bootstrap-responsive.min.css" rel="stylesheet">
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script>
</head>
<body>
<div id="main">
<div class="utility-nav navbar navbar-fixed-top">
<div class="navbar-inner">
<div class="container">
{# Navbar goes here. #}
</div>
</div>
</div>
<div class="content container">
{% block main %}{% endblock main %}
</div>
</div>
</body>
</html>
and
{% extends 'base.html' %}
{% block title %}Page Title{% endblock title %}
{% block main %}
<h2>This is a child template.</h2>
{% endblock main %}
And then i have the following function
from flask.ext.restful import Resource,request,reqparse
from app.business.login import Login
from app.business.appointments import Appointments
from app.models.models import User, Address,Appointment
from flask import render_template
class AppointmentController(Resource):
def __init__(self):
pass
def get(self):
return render_template('index.html')
so when i start the server up and say http://0.0.0.0:5000/appointment i get
"<!DOCTYPE html>\n <html lang=\"en\">\n <head>\n <title>Page Title</title>\n \n <link href=\"http://netdna.bootstrapcdn.com/bootswatch/2.3.2/united/bootstrap.min.css\" rel=\"stylesheet\">\n <link href=\"http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/css/ bootstrap-responsive.min.css\" rel=\"stylesheet\">\n <script src=\"http://code.jquery.com/jquery-1.9.1.min.js\"></script>\n <script src=\"http://netdna.bootstrapcdn.com/twitter-bootstrap/2.3.2/js/bootstrap.min.js\"></script>\n</head>\n<body>\n <div id=\"main\">\n <div class=\"utility-nav navbar navbar-fixed-top\">\n <div class=\"navbar-inner\">\n <div class=\"container\">\n \n </div>\n </div>\n </div>\n <div class=\"content container\">\n \n\t<h2>This is a child template.</h2>\n\n </div>\n </div>\n</body>\n</html>"
Meaning the templates are working but the browser is treating the response as a String and not html. What am i doing wrong.
解决方案
I modified the get accordingly. Setting the content type did the trick.
class AppointmentController(Resource):
def __init__(self):
pass
def get(self):
headers = {'Content-Type': 'text/html'}
return make_response(render_template('index.html'),200,headers)
