标签：python,solr
测试代码1：
def test(self):
data = {"add": {"doc": {"id": "100001", "*字段名*": u"我是一个大好人"}}}
params = {"boost": 1.0, "overwrite": "true", "commitWithin": 1000}
url = 'http://127.0.0.1:8983/solr/mycore/update?wt=json'
headers = {"Content-Type": "application/json"}
r = requests.post(url, json=data, params=params, headers=headers)
print r.text
def Index_data(self):
solr = pysolr.Solr('http://127.0.0.1:8983/solr/mycore/', timeout=10)
# How you'd index data.
result = solr.add([
{
"id": "doc_1",
"title": "A test document",
},
{
"id": "doc_2",
"title": "The Banana: Tasty or Dangerous?",
},
])
print result
测试代码2：
实际数据：
def Index_Data_FromCSV(self, csvfile):
'''
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
:return:
'''
list = CSVOP.ReadCSV(csvfile)
index = 0
doc = {}
params = {"boost": 1.0, "overwrite": "true", "commitWithin": 1000}
url = 'http://127.0.0.1:8983/solr/mycore/update?wt=json'
headers = {"Content-Type": "application/json"}
for item in list:
if index > 0: # 第一行是标题
try:
doc['title'] = item[0].decode('GB2312')
doc['link'] = item[1]
# doc['date'] = item[2]
doc['source'] = item[3].decode('GB2312')
doc['keyword'] = item[4].decode('GB2312')
data = {"add": {"doc": doc}}
r = requests.post(url, json=data, params=params, headers=headers)
print r.text
except Exception,e:
print e.message
print index
index += 1
#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
:return:
'''
list = CSVOP.ReadCSV(csvfile)
index = 0
listdocs = []
for item in list:
if index > 0: # 第一行是标题
doc = {}
try:
doc['title'] = item[0].decode('GB2312')
doc['link'] = item[1]
# doc['date'] = item[2]
doc['source'] = item[3].decode('GB2312')
doc['keyword'] = item[4].decode('GB2312')
listdocs.append(doc)
except Exception,e:
print e.message
index += 1
solr = pysolr.Solr(url, timeout=10)
result = solr.add(listdocs)
print result
查询代码：
def search_data(self,message='视频'):
url = 'http://127.0.0.1:8983/solr/mycore/select?q=title:"\％s"&wt=json&indent=true' ％ message
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：
{
"responseHeader":{
"status":0,
"QTime":0,
"params":{
"q":"title:\"\\视频\"",
"indent":"true",
"wt":"json"}},
"response":{"numFound":123,"start":0,"docs":[
