Object
(
[content:HttpResponse:private] => 1
[body:HttpResponse:private] =>
[header:HttpResponse:private] => 1
[requestId:HttpResponse:private] =>
[errorMessage:HttpResponse:private] =>
[contentType:HttpResponse:private] => application/json; charset=UTF-8
[httpStatusCode:HttpResponse:private] => 200
)

怎么过滤掉：HttpResponse Object
