GET employee/info/_search
{
"query":{
"bool": {
"should": [
{"match": {"name": "Rodri"}},
{"match": {"name": "Massadra"}}
]
}
}
}
如何从ElasticSearch获取响应。此查询在Sense中有效。 这就是我尝试从ElasticSearch获取响应的方法:编码字符串并调用ElasticSearch
package main
import (
"fmt"
"io/ioutil"
"net/http"
"net/url"
)
func main() {
query := `{
"query":{
"bool": {
"should": [
{"match": {"name": "Rodri"}},
{"match": {"name": "Massadra"}}
]
}
}
}`
query = url.QueryEscape(query)
resp, err := http.Get("http://localhost:9200/employee/info/_search?q=" + query)
if err != nil {
panic(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
panic(err)
}
fmt.Printf("\n%s", body)
}
这是我得到的错误:
{"error":{"root_cause":[{"type":"query_parsing_exception","reason":"

我也试试这个client,但我找不到从字符串查询中使用它的方法。
谢谢

一般来说,在发送有效负载时,您应该使用POST而不是GET(即使ES接受GET请求中的有效负载)。
请尝试使用此代码:
package main
import (
"bytes"
"fmt"
"io/ioutil"
"net/http"
)
func main() {
url := "http://localhost:9200/employee/info/_search"
query := []byte(`{
"query":{
"bool": {
"should": [
{"match": {"name": "Rodri"}},
{"match": {"name": "Massadra"}}
]
}
}
}`)
req, err := http.NewRequest("POST", url, bytes.NewBuffer(query))
req.Header.Set("Content-Type", "application/json")
client := &http.Client{}
resp, err := client.Do(req)
if err != nil {
panic(err)
}
defer resp.Body.Close()
body, err := ioutil.ReadAll(resp.Body)
if err != nil {
panic(err)
}
fmt.Printf("\n%s", string(body))
}
