ElasticSearch的聚类时出现fielddata=true

Expected map for property [fields] on field [subject_id] but got a class java.lang.String

错误代码：

data = {"properties":{"camera_position": "text",'fielddata': True}
}

正确代码：

data = { "properties":{ "camera_position": {'type':"text", 'fielddata': True }} }

完整代码：

import json
import requestsheader = {'Content-Type': 'application/json'}def set_fielddata(index='event_tk'):try:data = {"properties":{"camera_position": {'type':"text",'fielddata': True}}}DNS_API = 'http://127.0.0.1:9200/' + index + '/_mapping/koala-index'  # dns_test_v2为索引名# resp = requests.delete(DNS_API, headers=header)resp = requests.put(DNS_API, headers=header, data=json.dumps(data))print(resp.status_code)if resp.status_code == 200:print(u"set_fielddata ok")else:print(resp.text)except Exception as e:print(e, u"建立索引失败")def max_count(index='event_tk'):try:data={'index' : { "max_result_window" : 100000000}}DNS_API = 'http://192.168.1.152:9200/'+index+'/_settings'  # dns_test_v2为索引名# resp = requests.delete(DNS_API, headers=header)resp = requests.put(DNS_API, headers=header, data=json.dumps(data).encode())print(resp.status_code)if resp.status_code == 200:print(u"max ok")else:print(resp.text)except Exception as e:print(e, u"建立索引失败")if __name__ == '__main__':set_fielddata()# max_count()
