一、用django框架获取全国天气
在我们开始做项目的步骤大概分为四个步骤：
准备阶段
1.首先，我们在桌面建一个新的文件夹，然后在在这个文件夹里新建项目（在终端里代码创建），新建App，操作过程如下图所示：
2. -建好项目与App后，我们还需要引入js，还要建立一个模板页，最终成功的页面如下：
3.配置阶段
1.在setting里面，需要修改三处

2.在url里面
3.views里面
4.获取信息并做一下简单处理
from django.shortcuts import render
import requests
# Create your views here.
def index(request):
if request.method == 'POST':
city = request.POST['city']
url = 'http://api.map.baidu.com/telematics/v3/weather?location={}&output=json&ak=TueGDhCvwI6fOrQnLM0qmXxY9N0OkOiQ&callback=?'.format(city)
else :
url = 'http://api.map.baidu.com/telematics/v3/weather?location=%E9%83%91%E5%B7%9E&output=json&ak=TueGDhCvwI6fOrQnLM0qmXxY9N0OkOiQ&callback=?'
json_data = requests.get(url).json()
weather = json_data['results'][0]['weather_data']
today_weather = weather[0]
t_weather = weather[1]
tt_weather = weather[2]
ttt_weather = weather[3]
city = json_data['results'][0]['currentCity']
context = {
'today':today_weather ,
'city' : city ,
'list': [t_weather ,tt_weather,ttt_weather]
}
return render(request ,'index.html' , context)
5.最后在templates模板里面的index里面进行配置
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>{{city}}天气信息</title>
<style>
html ,body{
height:100%;
margin:0;
color: white;
text-align: center;
}
body{
background:linear-gradient(#1078c7,#7196b4);
}
form {
text-align: center;
}
main img {
width:80px;
}
h1 {
margin:5px;
}
footer{
display: flex;
margin-top:100px;
}
section{
flex-grow:1;
border-right:1px solid greenyellow;
}
section:last-child
{
border: none;
}
</style>
</head>
<body>
<form action="/select/" method="POST">
{% csrf_token %}
<input name="city" type="text" placeholder="请输入城市">
<button type="submit">查询</button>
</form>
<main>
<h2>实时天气</h2>
<img src="{{today.dayPictureUrl}}" alt="">
<h1>{{today.temperature}}</h1>
<div>
{{today.weather}} <br>
{{today.wind}} <br>
{{today.date}} <br>
</div>
</main>
<footer>
{% for weather in list %}
<section>
<h4>{{weather.date}}</h4>
<img src="{{weather.dayPictureUrl}}" alt="">
<div>
{{weather.temperature}} <br>
{{weather.weather}} <br>
{{weather.wind}} <br>
</div>
</section>
{% endfor %}
</footer>
</body>
</html>5.最后是展现页面
