title: python api request, service key Is not registered
body: <p>The first time I deal with APIs.</p>
  
  <p>The variable named : key corresponds to the authentication key.</p>
  
  <p>The authentication key is not really that value.</p>
  
  <p>I linked the site below.</p>
  
  <p>This is the authentication key issued by the public agency.</p>
  
  <p>Could you please tell me how I got the code wrong?</p>
  
  <pre><code>from urllib2 import Request, urlopen
  from urllib import urlencode, quote_plus
  
  key='anzxIHbtJcwtftW%2BRdGwUw%3D%3D'
  url = 'http://apis.data.go.kr/B551182/hospInfoService/getHospBasisList'
  queryParams = '?' + urlencode({ quote_plus('ServiceKey') : key, quote_plus('ServiceKey') : '-', quote_plus('pageNo') : '1', quote_plus('numOfRows') : '10', quote_plus('sidoCd') : '110000', quote_plus('sgguCd') : '110019', quote_plus('emdongNm') : '신내동', quote_plus('yadmNm') : '서울의료원', quote_plus('zipCd') : '2010', quote_plus('clCd') : '11', quote_plus('dgsbjtCd') : '01', quote_plus('xPos') : '127.09854004628151', quote_plus('yPos') : '37.6132113197367', quote_plus('radius') : '3000' })
  
  request = Request(url + queryParams)
  request.get_method = lambda: 'GET'
  response_body = urlopen(request).read().decode('utf8')
  print(response_body)
  </code></pre>
  
  <p>And I got the error like below</p>
  
  <p>SERVICE_KEY_IS_NOT_REGISTERED_ERROR</p>
