Python 2.7 urllib3.HTTPSConnectionPool错误

我尝试多次请求RestAPI资源。为了节省时间，我尝试使用urllib3.HTTPSConnectionPool而不是urllib2。但是，它不断向我抛出以下错误：

Traceback (most recent call last):
  File "LCRestapi.py", line 135, in <module>
    listedLoansFast(version, key, showAll='false')
  File "LCRestapi.py", line 55, in listedLoansFast
    pool.urlopen('GET',url+resource,headers={'Authorization':key})
  File "/Library/Python/2.7/site-packages/urllib3/connectionpool.py", line 515, in urlopen
    raise HostChangedError(self, url, retries)
urllib3.exceptions.HostChangedError: HTTPSConnectionPool(host='https://api.lendingclub.com/api/investor/v1/loans/listing?showAll=false', port=None): Tried to open a foreign host with url: https://api.lendingclub.com/api/investor/v1/loans/listing?showAll=false

谢谢你的帮助

问题是您正在创建一个

PoolManager

，但从未使用过它。相反，您还创建了一个

HTTPSConnectionPool

（绑定到特定主机）并使用它来代替

PoolManager

。

PoolManager

将代表您自动管理

HTTPSConnectionPool

对象，因此您无需担心

这应该起作用：

# Your example called this `manager`
http = urllib3.PoolManager()

url = 'https://api.lendingclub.com/api/investor/v1/loans/listing?showAll=false'
headers = {'Authorization': key}

# Your example did url+resource, but let's assume the url variable
# contains the combined absolute url.
r = http.request('GET', url, headers=headers)
print r.data

如果愿意，您可以指定

PoolManager

的大小，但除非您试图将资源限制在线程池中，否则不需要指定

# Your example called this `manager`
http = urllib3.PoolManager()

url = 'https://api.lendingclub.com/api/investor/v1/loans/listing?showAll=false'
headers = {'Authorization': key}

# Your example did url+resource, but let's assume the url variable
# contains the combined absolute url.
r = http.request('GET', url, headers=headers)
print r.data
