新版的elasticsearch在使用curl创建索引的时候报错：
:"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406
解决办法：指定请求头即可
curl -H "Content-Type: application/json" -XPUT 'http://127.0.0.1:9200/kc22k2_test' -d '
实例：
curl -H "Content-Type: application/json" -XPOST 'http://127.0.0.1:9200/kc22k2_test/cz' -d '{
"akc190" : { "type" : "string", "index" : "not_analyzed" },
"aac001" : { "type" : "string", "index" : "not_analyzed" },
"akc194" : { "type" : "date", "format": "dateOptionalTime" },
"id_drg" : { "type" : "string", "index" : "not_analyzed" },
"name_drg" : { "type" : "string", "index" : "not_analyzed" },
"id_mdc" : { "type" : "string", "index" : "not_analyzed" },
"name_mdc" : { "type" : "string", "index" : "not_analyzed" }
}'
--官网实例：
curl -XPUT 'localhost:9200/test?pretty' -H 'Content-Type: application/json' -d'
{
"settings" : {
"number_of_shards" : 1
},
"mappings" : {
"type1" : {
"properties" : {
"field1" : { "type" : "text" }
}
}
}
}
