fail to notify ding

[ranrinc]

my config.json

    {
        "notifications":{
            "dingding":{
                "url": "https://oapi.dingtalk.com/robot/send?access_token=blablablablablalba",
                "requestType":"POST",
                "headers":{
                    "Content-Type":"application/json"
                }
            }
        },
        "requests":[
            {
                "url":"http://www.example.com",
                "requestType":"GET",
                "checkEvery":30,	
                "responseTime":800
            }
        ]
    }

Base on statusOK it did show success and error.. however no notification? Do I missing something?

May it's a bug. I first tested with dingding, no notification received either. Then I tesed with slack, everything works fine.
