从另一个视图调用我的服务器上的API

Question

所以,这里有一种奇怪的情况.我有一个Django项目,使用TastyPie为其API和一些视图/模板提供动力,这些视图/模板将用于为各种站点提供插件.我没有将这个插件构建为标准的Django模板,而是被要求使用我们的API来处理对插件的请求,这意味着我从另一个视图调用我的服务器上的视图,并且由于某些原因无效我的任何观点.以供参考:

#views.py
from django.http import HttpResponse
from django.shortcuts import render_to_response
from django.template.context import Context, RequestContext
import json, urllib, urllib2

SITE_NAME = "http://localhost:8000/"
API_PATH = "api/v1/"

def aggregate(request):
    template = 'lemonwise/plugins/aggregate.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib.urlopen(url).read())['objects'][0]
    return render_to_response(template, product)

def reviews(request):
    template = 'lemonwise/plugins/reviews.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?format=json&sku=', sku])
    #Comment the next line out and the url is passed correctly
    response = urllib2.build_opener().open(url).read()
    return HttpResponse(url)
    #page = opener.open(url).read()
    #return HttpResponse(url)
    #product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    #return HttpResponse(url)
    #reviews = [json.loads(urllib.urlopen(SITE_NAME + uri)) for uri in product['reviews']]
    #return render_to_response(template, {'reviews': reviews})

def survey(request):
    template = 'lemonwise/plugins/survey.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    return render_to_response(template, product)

def mosthelpfulpositive(request):
    template = 'lemonwise/plugins/mosthelpfulpositive.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    uri = product['most_helpful_positive']
    most_helpful_positive = json.loads(urllib.urlopen(SITE_NAME + uri))
    return render_to_response(template, most_helpful_positive)

def mosthelpfulnegative(request):
    template = 'lemonwise/plugins/mosthelpfulnegative.html'
    sku = request.GET.get('sku')
    url = ''.join([SITE_NAME, API_PATH, 'product/?sku=', sku])
    product = json.loads(urllib2.build_opener().open(url).read())['objects'][0]
    uri = product['most_helpful_negative']
    most_helpful_negative = json.loads(urllib.urlopen(SITE_NAME + uri))
    return render_to_response(template, most_helpful_negative)

和相应的urls.py(在不同的应用程序中):

#urls.py    
from django.conf import settings
from django.conf.urls.defaults import patterns, include, url
from django.contrib import admin
from django.contrib.staticfiles.urls import staticfiles_urlpatterns

from tastypie.api import Api
from lemonwise.reviews.api import *

admin.autodiscover()

v1_api = Api(api_name='v1')
v1_api.register(UserResource())
v1_api.register(MerchantResource())
v1_api.register(ProductFamilyResource())
v1_api.register(ProductResource())
v1_api.register(BooleanAttributeResource())
v1_api.register(SlideAttributeResource())
v1_api.register(ProductAttributeResource())
v1_api.register(SubmissionResource())
v1_api.register(ReviewResource())
v1_api.register(ReviewProductAttributeResource())
v1_api.register(CommentResource())
v1_api.register(BestUseResource())
v1_api.register(HelpfulVoteResource())

#Acess the api via http://127.0.0.1:8000/api/v1/user/?format=json

urlpatterns = patterns('',
    url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
    url(r'^admin/', include(admin.site.urls)),

    # Lemonwise apps
    url(r'^reviews/', include('lemonwise.reviews.urls')),

        #API
        url(r'^api/', include(v1_api.urls)),
)

if settings.DEBUG:
    urlpatterns += staticfiles_urlpatterns()

有关如何解决此问题的任何想法？我找不到关于这个问题的任何着作.

编辑:更具体地说,发生的事情是,当我加载任何这些视图时,他们会尝试阅读api页面.此外,我的服务器没有显示任何处理请求的迹象.(虽然我可以直接加载api页面.)

现在您的评论澄清了情况,我可以猜测问题是什么.您使用的是内置开发服务器,它是单线程的.因此,当它处理原始请求时,它无法处理另一个URL的内部请求 - 因此它会无限期挂起.

正如毛泽东指出的那样,解决方案是想出一个更好的架构.如果你不能这样做,你可能会有使用像gunicorn而不是内置服务器的运气.
