$ Django 调API的几种方式

django自定义错误响应

　　前提:settings.py

   #debug为true时要配置网站的allowed_hosts域名
   # 简单就为"*"
   DEBUG = False
   ALLOWED_HOSTS = ['127.0.0.1']

直接templates下书写404.htm,400.html,403.html,500.html

方式1

#第一步:总的urls.py 重写handler函数，(注意要加项目app名  要写在上面)
from django.conf.urls import url
from django.contrib import admin
from app01 import views
# handler404="app01.views.erro"
# handler400="app01.views.erro"
# handler403="app01.views.erro"
# handler500="app01.views.erro"

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^download/', views.Download),#下载
    url(r'^file/', views.File.as_view()),#播放
    url(r'^tes/', views.tes),#test
    url(r'^data/', views.date),#test
]
#第二步:views.py写错误调的视图
from django.http import HttpResponseNotFound
def erro(request):
    return HttpResponseNotFound("NOT FOUND!")

API调用方式

下面是python中会用到的库。
urllib2
httplib2
pycurl
requests
urllib2

#request
import requests, json
github_url = ”
data = json.dumps({‘name’:’test’, ‘description’:’some test repo’})
r = requests.post(github_url, data, auth=(‘user’, ‘*‘))
print r.json
#以上几种方式都可以调用API来执行动作，但requests这种方式代码最简洁，最清晰，建议采用。

#urllib2, urllib
import urllib2, urllib
github_url = ‘https://api.github.com/user/repos’
password_manager = urllib2.HTTPPasswordMgrWithDefaultRealm()
password_manager.add_password(None, github_url, ‘user’, ‘*‘)
auth = urllib2.HTTPBasicAuthHandler(password_manager) # create an authentication handler
opener = urllib2.build_opener(auth) # create an opener with the authentication handler
urllib2.install_opener(opener) # install the opener…
request = urllib2.Request(github_url, urllib.urlencode({‘name’:’Test repo’, ‘description’: ‘Some test repository’})) # Manual encoding required
handler = urllib2.urlopen(request)
print handler.read() 

#httplib2
import urllib, httplib2
github_url = ’
h = httplib2.Http(“.cache”)
h.add_credentials(“user”, “**“, ”
data = urllib.urlencode({“name”:”test”})
resp, content = h.request(github_url, “POST”, data)
print content 

#pycurl
import pycurl, json
github_url = ”
user_pwd = “user:*”
data = json.dumps({“name”: “test_repo”, “description”: “Some test repo”})
c = pycurl.Curl()
c.setopt(pycurl.URL, github_url)
c.setopt(pycurl.USERPWD, user_pwd)
c.setopt(pycurl.POST, 1)
c.setopt(pycurl.POSTFIELDS, data)
c.perform()
