猜谜游戏

	"os"
	"strconv"
	"strings"
	"time"
)

func main() {
	maxNum := 100
	rand.Seed(time.Now().UnixNano())  //生成随机数种子
	secretNumber := rand.Intn(maxNum) //生成一个0-100随机数
	fmt.Println("要猜测的数字是 ", secretNumber)
	fmt.Println("请输入你猜测数的数字")

	reader := bufio.NewReader(os.Stdin) //从键盘读入

	for {

		guess, err := strconv.Atoi(input)//字符串转成int整数
		if err != nil {
			fmt.Println("无效输入，请输入一个整数")
			continue
		}
		fmt.Println("你的猜测是 ", guess)

在线词典 - 抓包

右键检查，找到请求，复制cUrl,

用刚刚复制的cUrl生成代码，链接

代码

package main

import (
	"fmt"
	"io/ioutil"
	"log"
	"net/http"
	"strings"
)

func main() {
	client := &http.Client{}
	var data = strings.NewReader(`{"trans_type":"en2zh","source":"good"}`)
	req, err := http.NewRequest("POST", "https://api.interpreter.caiyunai.com/v1/dict", data)

运行，就输出了一串json格式的字符串。

package main

import (
	"bufio"
	"fmt"
	"math/rand"
	"os"
	"strconv"
	"strings"
	"time"
)

func main() {
	maxNum := 100
	rand.Seed(time.Now().UnixNano())
	secretNumber := rand.Intn(maxNum)
	// fmt.Println("The secret number is ", secretNumber)

	fmt.Println("Please input your guess")
	reader := bufio.NewReader(os.Stdin)
	for {
		input, err := reader.ReadString('\n')
		if err != nil {
			fmt.Println("An error occured while reading input. Please try again", err)
			continue
		}
		input = strings.TrimSuffix(input, "\n")

		guess, err := strconv.Atoi(input)
		if err != nil {
			fmt.Println("Invalid input. Please enter an integer value")
			continue
		}
		fmt.Println("You guess is", guess)
		if guess > secretNumber {
			fmt.Println("Your guess is bigger than the secret number. Please try again")
		} else if guess < secretNumber {
			fmt.Println("Your guess is smaller than the secret number. Please try again")
		} else {
			fmt.Println("Correct, you Legend!")
			break
		}
	}
