curl 如何传 JSON参数 给opentsdb的 api/query？

[AdairJun]

我使用以下命令是成功的：
curl -d start=1h-ago -d m="avg:proc.loadavg.10m{host=*}" -d ascii= --get http://10.4.22.187:4242/api/query
但是我想传JSON对象时失败了：
curl -d '{"start":1h-ago,"m":[{"aggregator":avg,"metric":proc.loadavg.10m,"tags":{"host":"*",}}] }' http://10.4.22.187:4242/api/query
这个问题怎么fix啊？或者大神给我一个传JSON对象给 api/query的例子吧。

这个json格式有问题 修改后的json

{
    "start": "1h-ago",
    "m": [
        {
            "aggregator": "avg",
            "metric": "proc.loadavg.10m",
            "tags": {
                "host": "*"
            }
        }
    ]
}

看错误提示还是json有问题，换个最简单的json试试呢，比如：{"name":"1111"}

是你的json数据组成方式，不对，具体可以参考 http://opentsdb.net/docs/build/html/api_http/put.html 下面我写的一个 curl -d '{"start": 1460451066,"queries": [{"aggregator": "sum","metric": "mysql.bytes_sent","tags": {"host": "*"}}]}' http://127.0.0.1:4242/api/query
