Python 在uwsgi下，如何使用urllib2.urlopen连接到其他服务？

我正在使用nginx+uwsgi+烧瓶。在flask中，我需要使用urllib2.urlopen访问google翻译API。我只需运行flask的.py文件就可以得到正确的结果。但一旦我连接到uWSGI，它总是有分段错误

我的uWSGI.ini：

[uwsgi]
socket = 127.0.0.1:10001
chdir = /Users/xingshi/Workspace/misc/howToSpeak/flask/py
wsgi-file = api.py 
pyargv = ../config/mac.cfg
callable = app
processes = 4
threads = 2
stats = 127.0.0.1:10002
master = true
harakiri = 60

调用urllib2的Python代码段

query = urllib.urlencode(fields)
url = 'https://www.googleapis.com/language/translate/v2?'+query
print url
json_str = urllib2.urlopen(url).read()
print json_str

分段错误：

只需使用urllib3

解决方法：

使用no_proxy='*'运行代码似乎可以阻止它尝试加载代理设置。

能否引用源代码？由于链接腐烂，不鼓励简单地链接到答案。

url = 'https://www.googleapis.com/language/translate/v2?'+query
http = urllib3.PoolManager()
r = http.request('GET',url)
json_str = r.data
