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 ftimport ( "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
高性能API演示
下面分享使用更高的性能（基于对象池）的API创建请求和获取响应的方式：

Golang单元测试
第一次写Golang单测，有点不适应，搞了很久才通。
