Question

概述：我使用urllib2和json库调用python2.7的API。当我运行脚本时，如果结果计数高于20，我会收到以下错误：

错误：[Errno 10054]现有连接被强行关闭远程主机

脚本：

import json
import urllib2
import webbrowser

url = "http://poi.????.com:xxxx/k/search?name==smith&limit==30"

response = urllib2.urlopen(url)
webbrowser.open(url)
data = json.load(response)

count = "count = "+str(data['count'])
print count
for i in data['results']:
        name = i['name']
        print name

预期结果：我运行脚本，API以“200 OK”状态响应，我的webbrowser.open（url）行在我的浏览器中打开响应。我的IDLE shell打印输出。

问题：当我在API中使用limit参数并将其设置为＆lt; 20时，它会在我的IDLE shell中按预期响应。但是，如果我设置限制＆gt; 20或者没有设置限制，我仍然得到200 OK响应，浏览器填充结果但我的IDLE shell产生'连接被强制关闭'错误。

软件：我在Windows 7/8和Ubuntu 14.04上试过这个。在家里通过VPN和在有线网络上工作。

IDLE的追踪电话：

Traceback (most recent call last):
  File "C:\Users\xxx\userQueryService.py", line 9, in <module>
    data = json.load(response)
  File "C:\Python27\lib\json\__init__.py", line 286, in load
    return loads(fp.read(),
  File "C:\Python27\lib\socket.py", line 351, in read
    data = self._sock.recv(rbufsize)
  File "C:\Python27\lib\httplib.py", line 573, in read
    s = self.fp.read(amt)
  File "C:\Python27\lib\socket.py", line 380, in read
    data = self._sock.recv(left)
error: [Errno 10054] An existing connection was forcibly closed by the remote host

Ubuntu python shell中的回溯调用：

>>> data = json.load(response)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/json/__init__.py", line 290, in load
    **kw)
  File "/usr/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/usr/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Unterminated string starting at: line 1 column 43303 (char 43302)

我设法通过使用请求库而不是 urllib2 和 json 来解决我的问题。我为那些有类似问题的人提供了我的代码（注意我还包括一个异常处理程序）：

import webbrowser
import requests

url = "http://poi.????.com:xxxx/k/search?name==smith&limit==30"

r = requests.get(url)

try:
    data = r.json()
    webbrowser.open(url)
    count = "count = "+str(data['count'])
    print count
    for i in data['results']:
            name = i['name']
            print name

except IOError as (errno, strerror):
    print "I/O error({0}): {1}".format(errno, strerror)
