放置请求失败，无法solr

标签： python json solr

我有一个新的json文件，我想用新的json文件覆盖solr上的功能存储json文件。因此，我编写了以下代码：

filename ='_schema_feature-store.json'

import requests
import json
from requests.auth import HTTPBasicAuth


with open(filename) as json_f:
    solrModel = json.load(json_f)
    url = 'http://xx.xxx.xx.xx:xxxx/solr/someurl/' + "schema/feature-store"
    resp = requests.put(url, json.dumps(solrModel), auth=HTTPBasicAuth('username', 'password'))
    print(resp.text)

当然上面的网址是真实的网址。

但是在发送此请求时，我得到以下响应：

    "status":500,
    "QTime":1174},

，依此类推。我认为错误中最值得注意的部分是：

ts_title_0 already contained in the store

但是，我的新json文件仅包含一个ts_title_0，如下所示：

"name":"ts_title_0",

，这是整个文件中ts_title_0的唯一实例。那为什么会出现这个错误？

1 个答案:

答案 0 :(得分：0)

我认为您应该在request.post中使用更新网址。例如：

url='http://localhost:8983/solr/my_collection/update?commit=true'
payload=open(filename, 'rb').read()
headers={'Content-type':'application/csv'}
response = requests.post(url, auth=('user', 'passwd'), headers=headers, data=payload, timeout=5)`

检出Solr负载测试脚本，在该脚本中我多次更新相同的csv文件： https://github.com/itzmestar/solr/blob/master/solr_post.py

希望这会有所帮助
