httpc

Go的一个功能强大、易扩展、易使用的http客户端请求库。适合用于接口请求，模拟浏览器请求，爬虫请求。

特点

• Cookie管理器(适合爬虫和模拟请求)
• 支持HEADER、GET、POST、PUT、DELETE
• 轻松上传文件下载文件
• 支持断点下载断点续传(开发中)
• 支持链式调用

安装

快速入门

1. 简单的请求

//新建一个请求和http客户端
req:=httpc.NewRequest(httpc.NewHttpClient())
//get请求,返回string类型的body
resp,body,err:=req.SetUrl("http://127.0.0.1").Send().End()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(body)
}

2. 设置头信息

//新建一个http客户端
client:=httpc.NewHttpClient()
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息,返回byte类型的body
resp,bodyByte,err:=req.SetHeader("HOST","127.0.0.1").Send().EndByte()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(bodyByte)
}

3. 设置请求信息

//新建一个http客户端
client:=httpc.NewHttpClient()
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息
req.SetHeader("HOST","127.0.0.1")
//设置请求信息
resp,body,err:=req.SetData("client", "httpc").Send().End()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(body)
}

4. 设置Cookie

//新建一个http客户端
client:=httpc.NewHttpClient()
//新建一个请求
req:=httpc.NewRequest(client)
//设置请求地址和头信息
req.SetUrl("http://127.0.0.1").SetHeader("HOST","127.0.0.1")
//设置请求数据
req.SetData("client", "httpc")
var cookies []*http.Cookie
cookie:=&http.Cookie{Name:"client",Value:"httpc"}
cookies= append(cookies, cookie)
//添加cookie并请求
resp,bodyByte,err:=req.SetCookies(&cookies).Send().End()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(bodyByte)
}

5. 上传文件

//新建一个http客户端
client:=httpc.NewHttpClient()
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置上传的文件
req.SetFileData("img1","./img.png",true)
//设置附加参数
req.SetFileData("client","httpc",false)
resp,body,err:=req.Send(true).End()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(body)
}

6. 下载文件

//新建一个http客户端
client:=httpc.NewHttpClient()
//新建一个请求
req:=httpc.NewRequest(client)
//请求保存文件
resp,body,err:=req.SetUrl("http://127.0.0.1/1.zip").Send().EndFile("./test.zip")
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(body)
}

7. 开启调试

req:=httpc.NewRequest(httpc.NewHttpClient())
req.SetMethod("post").SetUrl("https://127.0.0.1")
req.SetHeader("HOST","127.0.0.1")
req.SetData("client","httpc")
var cookies []*http.Cookie
cookie:=&http.Cookie{Name:"client",Value:"httpc"}
cookies= append(cookies, cookie)
_, _, _ = req.SetCookies(&cookies).SetDebug(true).Send().End()

⚠ 在实际场景中不建议复用Request，建议每个请求对应一个Request。

高级用法

1. 设置请求超时

//新建http客户端
client:=httpc.NewHttpClient()
//设置请求超时,默认值为30秒
client.SetTimeout(5*time.Second)
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息,返回byte类型的body
resp,bodyByte,err:=req.SetHeader("HOST","127.0.0.1").Send().EndByte()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(bodyByte)
}

2. 设置COOKIE管理器

//新建http客户端
client:=httpc.NewHttpClient()
//新建一个cookie管理器,后面所有请求的cookie将保存在这
cookieJar:=httpc.NewCookieJar()
//设置cookie管理器,
client.SetCookieJar(cookieJar)
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息,返回byte类型的body
resp,bodyByte,err:=req.SetHeader("HOST","127.0.0.1").Send().EndByte()
if err!=nil {
    fmt.Println(err)
}else{
    //从cookie管理器中获取当前访问url保存的cookie
    u, _ := url.Parse("http://127.0.0.1")
    cookies:=cookieJar.Cookies(u)
    fmt.Println(cookies)
    fmt.Println(resp)
    fmt.Println(bodyByte)
}

3. 设置传输连接参数

//新建http客户端
client:=httpc.NewHttpClient()
//设置连接传输参数
client.SetTransport(&http.Transport{
    Proxy:                 http.ProxyFromEnvironment,
    MaxIdleConns:          100,
    IdleConnTimeout:       30 * time.Second,
    TLSHandshakeTimeout:   10 * time.Second,
    ExpectContinueTimeout: 1 * time.Second,
    ResponseHeaderTimeout: 10 * time.Second,
})
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息,返回byte类型的body
resp,bodyByte,err:=req.SetHeader("HOST","127.0.0.1").Send().EndByte()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(bodyByte)
}

4. 设置重定向处理

//新建http客户端
client:=httpc.NewHttpClient()
//设置http客户端重定向处理函数
client.SetRedirect(func(req *http.Request, via []*http.Request) error {
    return http.ErrUseLastResponse
})
//新建一个请求
req:=httpc.NewRequest(client)
req.SetMethod("post").SetUrl("http://127.0.0.1")
//设置头信息,返回byte类型的body
resp,bodyByte,err:=req.SetHeader("HOST","127.0.0.1").Send().EndByte()
if err!=nil {
    fmt.Println(err)
}else{
    fmt.Println(resp)
    fmt.Println(bodyByte)
}
