基本介绍
http 客户端支持对HTTP请求的输入与输出原始信息获取与打印，方便调试，相关方法如下：
func (r *Response) Raw() string
func (r *Response) RawDump()
func (r *Response) RawRequest() string
func (r *Response) RawResponse() string可以看到，所有的方法均绑定在 Response 对象上，也就是说必须要请求结束后才能打印。
使用示例
package main
import (
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gctx"
)
func main() {
response, err := g.Client().Post(
gctx.New(),
"https://goframe.org",
g.Map{
"name": "john",
},
)
if err != nil {
panic(err)
}
response.RawDump()
}执行后，终端输出为：
