  r = requests.post(url, json=data, params=params, headers=headers)
  print r.text


 def index_data(self):

#pysolr客户端代码
 def pysolr_index_data_fromcsv(self, csvfile,url='http://127.0.0.1:8983/solr/mycore/'):
  '''
   从csv文件中读取数据，并索引到solr中
   :param csvfile: csv文件，包括完整路径

    doc = {}
    try:

     doc['link'] = item[1]

查询代码：

def search_data(self,message='视频'):

  r = requests.get(url, verify=false)
  print r.text
  r = r.json()['response']['numfound']
  print message + ":" + str(r)
  
  #pysolr客户端
  def search_data(self,where='视频',url='http://127.0.0.1:8983/solr/mycore/'):
  solr = pysolr.solr(url, timeout=10)
  dict = {'start':10,'rows': 30,'fl':'title,keyword,source,link'}
  result = solr.search('title:视频',**dict)
  # result = solr.search('title:视频')
  # print result.raw_response['response']['numfound']

  for item in result:
   print 'keyword: %s'% item['keyword']
   print 'title: %s'% item['title']
   print 'source: %s'% item['source']
   print 'link: %s'% item['link']
   print '

输出结果：
