golang发送http请求

以下是两种golang发送http请求的例子：

1.使用http.NewRequest发送请求

import (
    "fmt"
    "net/http"
    "net/url"
)

func main() {
    apiUrl := "https://api.example.com/v1/users"
    data := url.Values{}
    data.Set("name", "John Doe")
    data.Set("email", "johndoe@example.com")

    req, err := http.NewRequest("POST", apiUrl, strings.NewReader(data.Encode()))
    if err != nil {
        panic(err)
    }

    req.Header.Set("Content-Type", "application/x-www-form-urlencoded")
    req.Header.Set("Authorization", "Bearer YOUR_ACCESS_TOKEN")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }

    fmt.Println(string(body))
}

2.使用http.Post发送请求

import (
    "fmt"
    "net/http"
    "strings"
)

func main() {
    apiUrl := "https://api.example.com/v1/users"
    data := url.Values{}
    data.Set("name", "John Doe")
    data.Set("email", "johndoe@example.com")

    resp, err := http.Post(apiUrl, "application/x-www-form-urlencoded", strings.NewReader(data.Encode()))
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    body, err := ioutil.ReadAll(resp.Body)
    if err != nil {
        panic(err)
    }

    fmt.Println(string(body))
}
