python - 无法将JSON发布到ElasticSearch-未找到uri [\]和方法[POST]的处理程序

Question

我尝试将一些数据(JSON格式)从mongoDB发布到elasticSearch。

这是我的代码:

首先，我从mongoDB中提取数据，然后尝试将每个“文档”发布到我的 flex 文件中，地址是“http://127.0.0.1:9200”。我添加了一个额外的函数“my converter(o)”，以使datetime对象可序列化。

from pymongo import MongoClient
import requests
import json
import datetime

mongo_host = 'localhost'
mongo_port = '27017'

client=MongoClient(mongo_host+':'+mongo_port)
db = client.cvedb
collection=db['cves']

def myconverter(o):
     if isinstance(o, datetime.datetime):
            return o.__str__()



try: db.command("serverStatus")
except Exception as e: print(e)
else: print("You are connected!")
cursor = collection.find({})
for document in cursor:

    headers={"content-type":"application/x-www-form-urlencoded"}

    url_base = 'http://127.0.0.1:9200'

    data=document

    data_parsed=(json.dumps(data, default = myconverter))

    print("#####")
    print("#####")
    print(data_parsed)
    print("#####")
    print("#####")

    req = requests.post(url_base,json=data_parsed)
    print (req.status_code)
    print (req.text)

    print("####")
    print("#####")
    print (req.status_code)
    print("#####")
    print("####")
client.close()

但是，当我访问我的ES时，其地址如下:“http://127.0.0.1:9200/_cat/indices”，什么也没有出现。这是我在终端机上得到的:

我尝试关注与处理相同问题的tome帖子，但对我无济于事。
知道为什么它不起作用吗？

有两个问题

url_base缺少索引和类型

url_base ='http://127.0.0.1:9200/index/type'

headers必须是application/json(您尚未看到此代码，但是一旦解决了上述问题，您也会收到此错误。

headers = {“content-type”:“application / json”}
