原计划学完Golang语言HTTP客户端实践之后,就可以继续了,没想到才疏学浅,在搜资料的时候发现除了Golang SDK自带的net/http,还有一个更牛的HttpClient实现github.com/valyala/fasthttp,据说性能是net/http的10倍,我想可能是有点夸张了,后期我会进行测试,以正视听。
在github.com/valyala/fasthttp用到了对象池,为了在高性能测试中减少内存的使用,fasthttp使用了两个对象池(我只看了这俩):requestPool sync.Pool和responsePool sync.Pool,当然fasthttp也提供了正常的对象创建API,后面我在案例中也会写到。
基础API演示
首先分享一下基础的用法封装:
PS:这个属于练习版本,所以没写多少注释。

package ft
import (
"encoding/json"
"fmt"
"funtester/task"
"github.com/valyala/fasthttp"
)
func FastGet(url string, args map[string]interface{}) ([]byte, error) {
uri := url + "?" + task.ToValues(args)
_, resp, err := fasthttp.Get(nil, uri)
if err != nil {
fmt.Println("请求失败:", err.Error())
return nil, err
}
return resp, err
}
func FastPostForm(url string, args map[string]interface{}) ([]byte, error) {
// 填充表单,类似于net/url
params := &fasthttp.Args{}
for s, i2 := range args {
sprintf := fmt.Sprintf("%v", i2)
params.Add(s, sprintf)
}
_, resp, err := fasthttp.Post(nil, url, params)
if err != nil {
fmt.Println("请求失败:", err.Error())
return nil, err
}
return resp, nil
}
func FastPostJson(url string, args map[string]interface{}) ([]byte, error) {
req := &fasthttp.Request{}
req.SetRequestURI(url)
marshal, _ := json.Marshal(args)
req.SetBody(marshal)
// 默认是application/x-www-form-urlencoded,其实无所谓
req.Header.SetContentType("application/json")
req.Header.SetMethod("POST")
resp := &fasthttp.Response{}
if err := fasthttp.Do(req, resp); err != nil {
fmt.Println("请求失败:", err.Error())
return nil, err
}
return resp.Body(), nil
}

其中两点主要注意:
- FastGet、FastPostForm使用的fasthttp提供的默认获取请求的方式,FastPostJson使用了自定义请求和获取响应的方式
- 关于请求头中的req.Header.SetContentType方法,其实无所谓,服务端都可以解析
