Go语言学习: http 之 get 请求

基本的 GET 请求使用

安装

• 原生包，不用安装

main.go

最简单的无参数形式  get 请求

package main

import (
	"io"
	"log"
	"net/http"
)

func main() {
	apiurl := "https://httpbin.org/get"
	response, _ := http.Get(apiurl)
	body, _ := io.ReadAll(response.Body)
	log.Printf("Response Body: %s", string(body))
}

带参数的 querystring 的情况

安装包: go get github.com/afeiship/nx

package main

import (
	"io"
	"log"
	"net/http"

	nx "github.com/afeiship/nx/lib"
)

func main() {
	data := make(map[string]any)
	data["name"] = "afei"
	data["age"] = 25
	apiurl := nx.Param(data, "https://httpbin.org/get")
	response, _ := http.Get(apiurl)
	body, _ := io.ReadAll(response.Body)
	log.Printf("Response Body: %s", string(body))
}

HTTP 带 Headers

package main

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

func main() {
	client := &http.Client{}

	// 创建请求，这里的 nil 不能为空
	req, err := http.NewRequest("GET", "https://httpbin.org/get", nil)
	if err != nil {
		fmt.Println("Error creating request:", err)
		return
	}

	// 添加 headers
	req.Header.Add("Authorization", "Bearer YOUR_TOKEN_HERE")
	req.Header.Add("Content-Type", "application/json")
	req.Header.Add("Custom-Header", "CustomValue")

	// 发送请求
	resp, err := client.Do(req)
	if err != nil {
		fmt.Println("Error making request:", err)
		return
	}
	defer resp.Body.Close()

	// 读取响应
	body, err := io.ReadAll(resp.Body)
	if err != nil {
		fmt.Println("Error reading response body:", err)
		return
	}

	fmt.Println("Response Status:", resp.Status)
	fmt.Println("Response Body:", string(body))
}

使用 Fetch 包

package main

import (
	"fmt"

	"github.com/go-zoox/fetch"
)

func main() {
	res, _ := fetch.Get("https://httpbin.org/get", &fetch.Config{
		Headers: map[string]string{
			"User-Agent":      "fetch-example/1.0",
			"X-Custom-Header": "custom-value",
		},
	})

	fmt.Println(res)
}
