goz 是一个用于在 Go 代码中快速发起 HTTP 请求的开源库， 部分实现参考了 PHP 流行请求库： guzzle
安装
go get -u github.com/idoubi/goz
文档
API 文档地址: https://godoc.org/github.com/idoubi/goz
基本使用
package main
import (
"github.com/idoubi/goz"
)
func main() {
cli := goz.NewClient()
resp, err := cli.Get("http://127.0.0.1:8091/get")
if err != nil {
log.Fatalln(err)
}
fmt.Printf("%T", resp)
// Output: *goz.Response
}
查询参数
- map 形式
cli := goz.NewClient()
resp, err := cli.Get("http://127.0.0.1:8091/get-with-query", goz.Options{
Query: map[string]interface{}{
"key1": "value1",
"key2": []string{"value21", "value22"},
"key3": "333",
},
})
if err != nil {
log.Fatalln(err)
}
fmt.Printf("%s", resp.GetRequest().URL.RawQuery)
// Output: key1=value1&key2=value21&key2=value22&key3=333
- 字符串形式
cli := goz.NewClient()
resp, err := cli.Get("http://127.0.0.1:8091/get-with-query?key0=value0", goz.Options{
Query: "key1=value1&key2=value21&key2=value22&key3=333",
})
if err != nil {
log.Fatalln(err)
}
fmt.Printf("%s", resp.GetRequest().URL.RawQuery)
// Output: key1=value1&key2=value21&key2=value22&key3=333
提交数据
- form 表单
cli := goz.NewClient()
resp, err := cli.Post("http://127.0.0.1:8091/post-with-form-params", goz.Options{
Headers: map[string]interface{}{
"Content-Type": "application/x-www-form-urlencoded",
},
FormParams: map[string]interface{}{
"key1": "value1",
"key2": []string{"value21", "value22"},
"key3": "333",
},
})
if err != nil {
log.Fatalln(err)
}
body, _ := resp.GetBody()
fmt.Println(body)
// Output: form params:{"key1":["value1"],"key2":["value21","value22"],"key3":["333"]}
- json 数据
cli := goz.NewClient()
resp, err := cli.Post("http://127.0.0.1:8091/post-with-json", goz.Options{
Headers: map[string]interface{}{
"Content-Type": "application/json",
},
JSON: struct {
Key1 string `json:"key1"`
Key2 []string `json:"key2"`
Key3 int `json:"key3"`
}{"value1", []string{"value21", "value22"}, 333},
})
if err != nil {
log.Fatalln(err)
}
body, _ := resp.GetBody()
fmt.Println(body)
// Output: json:{"key1":"value1","key2":["value21","value22"],"key3":333}
请求头
cli := goz.NewClient()
resp, err := cli.Post("http://127.0.0.1:8091/post-with-headers", goz.Options{
Headers: map[string]interface{}{
"User-Agent": "testing/1.0",
"Accept": "application/json",
"X-Foo": []string{"Bar", "Baz"},
},
})
if err != nil {
log.Fatalln(err)
}
headers := resp.GetRequest().Header["X-Foo"]
fmt.Println(headers)
// Output: [Bar Baz]
响应
cli := goz.NewClient()
resp, err := cli.Get("http://127.0.0.1:8091/get")
if err != nil {
log.Fatalln(err)
}
body, err := resp.GetBody()
if err != nil {
log.Fatalln(err)
}
fmt.Printf("%T", body)
// Output: goz.ResponseBody
part := body.Read(30)
fmt.Printf("%T", part)
// Output: []uint8
contents := body.GetContents()
fmt.Printf("%T", contents)
// Output: string
fmt.Println(resp.GetStatusCode())
// Output: 200
fmt.Println(resp.GetReasonPhrase())
// Output: OK
headers := resp.GetHeaders()
fmt.Printf("%T", headers)
// Output: map[string][]string
flag := resp.HasHeader("Content-Type")
fmt.Printf("%T", flag)
// Output: bool
header := resp.GetHeader("content-type")
fmt.Printf("%T", header)
// Output: []string
headerLine := resp.GetHeaderLine("content-type")
fmt.Printf("%T", headerLine)
// Output: string
代理
cli := goz.NewClient()
resp, err := cli.Get("https://www.fbisb.com/ip.php", goz.Options{
Timeout: 5.0,
Proxy: "http://127.0.0.1:1087",
})
if err != nil {
log.Fatalln(err)
}
fmt.Println(resp.GetStatusCode())
// Output: 200
超时
cli := goz.NewClient(goz.Options{
Timeout: 0.9,
})
resp, err := cli.Get("http://127.0.0.1:8091/get-timeout")
if err != nil {
