For all options use the manual or "--help all".

示例：

 curl -i -X GET http://es-cn-7pp2till2001ycze0.elasticsearch.aliyuncs.com:9200/imb_template/_search \
-H 'Content-Type: application/json; charset=utf-8' \
-H 'Authorization: Basic ZWxhc3RpYzpFcyNJbWdCJkUyMEUyMEAwR0lJ' \
-d '{ "_source": ["category"], "query": {"match_all": {}}, "profile": true}' | json

• 一行不够，可以输入 \ + enter 换行
• 这里‘| json’ 是用了 npm 安装的json库去格式化返回的json，方便阅读

  npm install -g json
