> Some APIs require parameters (e.g. digital signature) in the headers to be generated at access time.So I'm wondering if we can pass it in through filter statement.
> Perhaps we could design it like the params field in connections parameter. For example:
>  
> Config:
> { "url": "https://api.sunrise-sunset.org/json", "requireTail": false, "params": ["body.lat", "body.lng", "body.date", "header.header1"], "parameterLocation": "json_body" }
>  
> SQL Query:
> SELECT * FROM api.sunrise
> WHERE `body.lat` = 36.7201600
> AND `body.lng` = -4.4203400
> AND `body.date` = '2019-10-02'
> AND `header.header1` = 'value1';
>  
> Post body:
> { "lat": 36.7201600, "lng": -4.4203400, "date": "2019-10-02"}
>  
> Headers:
> { "header1": "value1", ……}
