Django REST Framework发布数据时出现文件错误（使用ModelResource）

我在Django REST Framework应用程序中试图用文件发布数据时遇到了一个很大的问题。我通过djangorestframework网站上的示例创建了一个简单的应用程序。所以我有URL文件：

class MyImageResource(ModelResource):
    model = Image

并以不同的方式：

url(r'^image/$', ListOrCreateModelView.as_view(resource=MyImageResource)),
url(r'^image/(?P<pk>[^/]+)/$', InstanceModelView.as_view(resource=MyImageResource)),

在浏览器中测试REST页面，效果完美。甚至用文件发布数据

我的问题是，我想创建一个简单的python应用程序来发布数据。我使用了简单的urllib2，但我得到500个内部错误或400个错误请求：

poza = open('poza.jpg', 'rb')


initial_data = (    
    {'name', 'Imagine de test REST'},
    {'description', 'Dude, this is awesome'},
    {'image', poza},
)

d = urllib.urlencode(initial_data)
r = urllib2.Request('http://localhost:8000/api/image/', data=d,
                headers={'Content-Type':'multipart/form-data'})
resp = urllib2.urlopen(r)
code = resp.getcode()
data = resp.read()

我也尝试过使用MultipartPostHandler：

import MultipartPostHandler, urllib2, cookielib
cookies = cookielib.CookieJar()

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookies),
                          MultipartPostHandler.MultipartPostHandler)

params = {
    "name":"bob",
    "description":"riviera",
    "content" : open("poza.jpg", "rb")
}

opener.open("http://localhost:8000/api/image/", params)

但是相同：500或400个错误，服务器（python manage.py runserver）停止并出现以下错误：

Exception happened during processing of request from ('127.0.0.1', 64879)
Traceback (most recent call last):

如果有人这样做了，请给我一个用文件发布数据的例子，或者告诉我发布python代码的错误。我找不到更多的例子了

服务器看起来不错，我可以在浏览器中发布数据。非常感谢。

看起来您不是在读取文件，而是在传递文件指针

尝试：

我不确定你的代码有什么问题。。。您应该尝试使用而不是urllib。这将有助于避免urllib带来的麻烦。您的机器上是否可能有某种防火墙挡住了您的去路？回复：“主机中的软件中止了已建立的连接”
