英文:
Dont insert document if already exists in Elasticsearch with Golang
问题
我是你的中文翻译助手，以下是翻译好的内容：
我刚开始学习golang，在Elasticsearch中插入具有相同id的新文档时遇到了困难。到目前为止，我可以正确地将文档插入索引中，但如果文档的id重复，时间戳会更新（因为这是唯一变化的内容）。然而，我希望的是不更新文档，换句话说，什么都不做。
在Python中，我通过以下方式实现了这一点：
es = Elasticsearch(
[elastic_url],
http_auth=(elastic_user, elastic_password),
verify_certs=True,
)
return es.create(index=index_name, id=document_id, body=data, ignore=409)
而在golang中，我使用以下代码：
req := esapi.IndexRequest{
Index: "test_index",
DocumentID: "2",
Body: strings.NewReader(data),
Refresh: "false",
}
res, err := req.Do(ctx, es)
如果能得到一些帮助就太棒了！提前谢谢！
英文:
I am new to golang and I'm struggling in inserting new documents with the same id in Elasticsearch. Until now I can insert the document correctly in the index, but if the document's id is repeated, the timestamp updates (because is the only thing that is changing). However, what I am looking to do is not to update the document, in other words, do nothing at all.
In the case of Python, to accomplish this I do the following thing:
es = Elasticsearch(
[elastic_url],
http_auth=(elastic_user, elastic_password),
verify_certs=True,
)
return es.create(index=index_name, id=document_id, body=data, ignore=409)
And in golang I'm using the following code:
req := esapi.IndexRequest{
Index: "test_index",
DocumentID: "2",
Body: strings.NewReader(data),
Refresh: "false",
}
res, err := req.Do(ctx, es)
It would be awesome some help! Thank you in advance!

在esapi中有一个API可用于检查特定索引中文档ID的存在性。
ExistRequest - 通过检查来自该请求的响应的状态码，我们可以确认该文档ID是否存在（如果存在则为200，如果不存在则为404）
// 准备存在性检查请求
req := esapi.ExistsRequest{
Index: index,
DocumentID: id,
}
// 发送存在性检查请求
// 这里的client是*elastic.Client
ctx := context.Background()
resp, err := req.Do(ctx, client)
if err != nil {
// 处理错误
}
status := resp.StatusCode
if status == 200 {
fmt.Println("存在")
} else if status == 404 {
fmt.Println("未找到")
}
英文:
There is an API available in esapi for checking existence of a document id in a particular index.
ExistRequest - By checking the status code of the response from this request we can confirm whether that document id is present or not (200 if present and 404 if not present)
// prepare existence checking request
req := esapi.ExistsRequest{
Index: index,
DocumentID: id,
}
// send existence checking request
// client here is *elastic.Client
ctx := context.Background()
resp, err := req.Do(ctx, client)
if err != nil {
// handle error
}
status := resp.StatusCode
if status == 200 {
fmt.Println("Exist")
} else if status == 404 {
fmt.Println("Not found")
}
