python - 如何批量更新Elasticsearch中的字段？

Question

def update(index):
    index = "twitter"
    list = ['0oPwSm4BxbPrifDrF7C1', 'r4MOWm4BxbPrifDrjbgR', 'y4NbWm4BxbPrifDrLLhh']
    data  = []
    for i in list:
        d = { "update" : {"_id" : i, "_index" : index, "retry_on_conflict" : 3} }
        e = { "doc" : {"answer_1" : "test"} }
        data.append(json.dumps(d))
        data.append(json.dumps(e))
    v = "\n".join(data)
    response = requests.post('https://url/_bulk', headers='application/x-ndjson', 
    data=json.loads(v)

我想批量更新不同文档的答案字段。我猜无法以正确的格式发送请求。

Answer 1

批量数据集应如下所示，

{'index': ''}\n
{'your': 'data'}\n
{'index': ''}\n
{'other': 'data'}\n

注意:换行符，即使在最后一行。

您现有的数据对我来说似乎还可以，

{"update": {"_id": "0oPwSm4BxbPrifDrF7C1", "retry_on_conflict": 3, "_index": "twitter"}}
{"doc": {"answer_1": "test"}}
{"update": {"_id": "r4MOWm4BxbPrifDrjbgR", "retry_on_conflict": 3, "_index": "twitter"}}
{"doc": {"answer_1": "test"}}
{"update": {"_id": "y4NbWm4BxbPrifDrLLhh", "retry_on_conflict": 3, "_index": "twitter"}}
{"doc": {"answer_1": "test"}}

您在 request.post()上遇到语法错误，错过了结尾括号 )，需要直接发送 v，而无需使用额外的 json.loads(v)

response = requests.post('https://url/_bulk', 
                         data=v,
                         headers={'content-type':'application/json', 
                         'charset':'UTF-8'})
print(response)
