问题描述
我已将Elasticsearch（5.5版）集成到Gitlab中并尝试使用它。这是我从外部Windows客户端发送的命令：
I have integrated Elasticsearch (Version 5.5) into Gitlab and try to use it. This is the command I send from an external windows client:
curl -XGET gitlab.server:9200/ -H 'Content-Type: application/json' -d '{"query": {"simple_query_string" : {"fields" : ["content"], "query" : "foo bar -baz"}}}'
，但是它不起作用。在客户端上，我得到以下错误：
but it doesn't work. On the client I get these errors:
在/var/log/elasticsearch/elasticsearch.log中的服务器上，我看不到任何日志消息。
On the server in /var/log/elasticsearch/elasticsearch.log I can see no log messages.
但是，正在运行上面与Linux服务器相同的确切命令使我得到没有错误的响应：
However, running the same exact command as above from the linux server gives me a response without errors:
{
"name" : "name",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "uuid",
"version" : {
"number" : "5.5.0",
"build_hash" : "260387d",
"build_date" : "2017-06-30T23:16:05.735Z",
"build_snapshot" : false,
"lucene_version" : "6.6.0"
},
"tagline" : "You Know, for Search"
}
我尝试将 http.content_type.required：true 添加到elasticsearch.yml，但问题是相同的。那么，我在这里做错了什么？为什么从Windows客户端获取不支持Content-Type标头？我该如何解决？
I tried adding http.content_type.required: true to the elasticsearch.yml, but the problem was the same. So, what am I doing wrong here? Why do I get a "Content-Type header not supported" from the Windows client? How can I solve this?
在将更改为之后：
curl -XGET gitlab.server:9200/ -H "Content-Type: application/json" -d "{"query": {"simple_query_string" : {"fields" : ["content"], "query" : "foo bar -baz"}}}"
我收到此回复：
{
"name" : "name",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "uuid",
"version" : {
"number" : "5.5.0",
"build_hash" : "260387d",
"build_date" : "2017-06-30T23:16:05.735Z",
"build_snapshot" : false,
"lucene_version" : "6.6.0"
},
"tagline" : "You Know, for Search"
}
curl: (6) Could not resolve host: bar
推荐答案
将封闭引号从'更改为 ，请在参数中使用引号 ，如下所示：
After changing the enclosing quotes from ' to ", escape the quotation marks " used inside the parameters as below:
curl -XGET gitlab.server:9200/ -H "Content-Type: application/json" -d "{\"query\": {\"simple_query_string\" : {\"fields\" : [\"content\"], \"query\" : \"foo bar -baz\"}}}"
另一个是将json放入文件中，并使用 @ 作为参数的前缀。
An alternative is to put the json into a file, and use the @ prefix for the parameters.
json.txt
{
"query": {
"simple_query_string" : {
"fields" : ["content"],
"query" : "foo bar -baz"
}
}
}
并按以下方式运行curl：
and run curl as below:
curl -XGET gitlab.server:9200/ -H "Content-Type: application/json" -d @json.txt
