如何让 cURL 仅输出 HTTP 响应正文(JSON)而不输出其他标头等

我在bash脚本中使用curl获取服务的响应，如下所示，

response=$(curl -isb -H "Accept: application/json" "http://host:8080/some/resource")

Service response is of json type and on browser I could perfectly fine response.
However curl response has other unwanted things (such as set-cookie, content-length header in this case) and sometimes the actual response is eaten up.

以下是echo $response&gt；

 Set-Cookie: rack.session=BAh7CEkiD3Nlc3Npb25faWQGOgZFVEkiRWJlY2JiOTE2M2Q1ZWI4NThjMDdi%0AYjRiOWRjMGMxMGEwYTBkMjE3NmJhZDVjYzY4YjY4ZTlmMTE2ZGVkYWE3MTMG%0AOwBGS

 tontent-Length: 354c8; path=/; HttpOnly

This is breaking my response parsing logic.
I have seen this happening intermittently which is weird.

Is there a way to get "only" json response from cUR output?
I went through the curl documentation but could not see any thing/ or I could have missed it.
