使用Django发出HTTP请求并反序列化输出 [英] Making HTTP request with Django and deserializing output
问题描述
所以我对整个Web开发几乎都是全新的,但是已经被投入到使用Django来提取和解析来自Web服务的数据的侧面项目中,并且正在努力理解事情是如何工作的,即使在寻找通过Django文档。
在Django中,我已经完成了所有设置并在基本级别工作(使用模板,显示的页面显示Hello World)。
现在为了从webservice中提取数据,我需要向以下格式的URL发出请求:
http://wbsapi.withings.net/ [service_name]?action = [action_name]& [parameters]
在提供的PHP示例中,他们使用cURL执行此操作,然后执行json_decode。
我会是什么?从Django获得类似的功能?提前致谢!
您可以使用 urllib2
和 json
标准模块(或者,优秀的图书馆请求和 json
):
import urllib2
import json
url ='http://wbsapi.withings.net/[service_name]?action=[action_name]&[parameters]'
serialized_data = urllib2.urlopen(url ).read()
data = json.loads(serialized_data)
您的 urls.py
将包含类似的内容
来自django.conf.ur ls导入模式,网址,包括
urlpatterns = patterns('',
(r'^ get_data / $','myapp.views.get_data'),
)
您的 myapp / views.py
将包含来自django.http的HttpResponse
import urllib2
import json
$ b
url ='http://wbsapi.withings.net/[service_name]?action=[action_name]&[parameters]'
serialized_data = urllib2.urlopen( url).read()
data = json.loads(serialized_data)
html =< html>< body>< pre>数据:%s。 < /预>< /体>< / HTML>中%json.dumps(data,indent = 2)
返回HttpResponse(html)
当然,我不知道您希望如何显示数据,所以我再次将其序列化:)
So I'm almost totally new to web development as a whole, but have been thrown into a side project using Django to pull and parse data from a web service, and am struggling to understand exactly how things work, even while looking through the Django documentation.
In Django, I have everything set up and working at a basic level (using templates, a page is displayed saying "Hello World").
Now in order to pull the data from the webservice, I need to make a request to a URL of the following format:
http://wbsapi.withings.net/[service_name]?action=[action_name]&[parameters]
In the provided PHP example, they do this using cURL, and then json_decode.
What would I do to get similar functionality out of Django? Thanks in advance!
You would use urllib2
and json
standard modules (or, alternatively, the excellent library requests and json
):
import urllib2
import json
url = 'http://wbsapi.withings.net/[service_name]?action=[action_name]&[parameters]'
serialized_data = urllib2.urlopen(url).read()
data = json.loads(serialized_data)
If you want it on a page, you want it in a view, which you will need to associate with an url.
Your urls.py
will contain something like
from django.conf.urls import patterns, url, include
urlpatterns = patterns('',
(r'^get_data/$', 'myapp.views.get_data'),
)
And your myapp/views.py
will contain something like
from django.http import HttpResponse
import urllib2
import json
def get_data(request):
url = 'http://wbsapi.withings.net/[service_name]?action=[action_name]&[parameters]'
serialized_data = urllib2.urlopen(url).read()
data = json.loads(serialized_data)
html = "<html><body><pre>Data: %s.</pre></body></html>" % json.dumps(data, indent=2)
return HttpResponse(html)
Of course, I don't know how you wanted your data to be displayed, so I just serialized it again :)
