golang自动登录https连接并解析得到的json返回值

https返回的json数据格式为

type item struct {
Id, List_type, Severity            int
list_type_string, Name, Expiration string
list_type_name, Severity_name      string
}
type resData struct {
Total_count, Total_page, Expect_page, Num_per_page int
Sort_by, Sort_order                                string
List                                               []item
}

{
"total_count" : 366,
"total_page" : 1,
"expect_page" : 1,
"num_per_page" : 10000000,
"sort_by" : "id",
"sort_order" : "desc",
"list" : [{ "id" : 3263, "list_type" : 2, "list_type_string" : "File", "name" : "4CDA46B428405E8A155A3AA32E4F25C8EA09B707", "severity" : 3, "expiration" : "11\/14\/2014 04:51:06", "list_type_name" : "File", "severity_name" : "High" }, { "id" : 3262, "list_type" : 2, "list_type_string" : "File", "name" : "ECC3F6D2CB227981C12038D620336617C8EC0B64", "severity" : 3, "expiration" : "11\/12\/2014 10:02:21", "list_type_name" : "File", "severity_name" : "High" } ] }
