elasticsearch异常报错：{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported

curl -XPOST http://localhost:9200/tracy/person/_mapping -d'
{
        "properties": {
            "content": {
                "type": "application/json",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word"
            }
        }

}'

执行报错：

{"error":"Content-Type header [application/x-www-form-urlencoded] is not supported","status":406}

解决：

curl -H "Content-Type: application/json" -XPOST http://localhost:9200/tracy/fulltext/_mapping -d'
{
        "properties": {
            "content": {
                "type": "text",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_max_word"
            }
        }
    

}'

原因：es6.0之后官方部分调整
