简介：

这是我参与「第三届青训营 -后端场」笔记创作活动的的第一篇笔记。
本篇文章是基于青训营5月7日的课程所展开的。该课程给我们分享了三个实战项目，分别是：猜谜游戏、命令行词典、SOCKS5代理；对于该三个实战项目，我后面会对前两个项目进行介绍，第三个有点难度，自己还得再深入理解一下，其次，课程结尾留有三个实战作业，我也完成了并进行记录于本文。

前提知识

在阅读本文之前，读者需要熟悉Go语言的基本语法，并能够进行相应的编码即可。

前言

在开展本文之前，我先给大家贴出本次课程的作业，以方便大家带着思考去阅读本文。

1. 猜谜游戏

该项目是基于一个简单的猜数字游戏，系统随机一个整数，玩家输入数字进行猜数环节，同时，系统也会给玩家进行相应的提示，比如玩家输入的数字比系统随机出的整数要大，就提示输入的数字过大，然后玩家根据系统提示进行相应的调整。

1.1 代码解析

由于系统要随机一个整数，因此我们得在程序里写一个生成随机数的方法，其GO语言的实现是：

maxNum := 100                            
rand.Seed(time.Now().UnixNano())         // 设置时间种子，每次生成随机数保证大概率不相同
secretNumber := rand.Intn(maxNum)

构造一个输入流，用于接收用户的输入情况，同时定义相关逻辑（用户输入的数比随机数要大，提示相应的信息）

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
   }
}

1.2 完整代码

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
      }
   }
}

由于作业要求，把输入流转为fmt.Scanf。下面就是由我完成代码的详细情况：

1.3 猜谜游戏作业

package main

import (
   "fmt"
   "math/rand"
   "time"
)
func randNum(maxNum int) int{
   rand.Seed(time.Now().UnixNano())
   secretNumber := rand.Intn(maxNum)
   return secretNumber
}
func doWork(guess int,secretNumber int) bool{
   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!")
      return true
   }
   return false
}
func main() {
   secretNumber := randNum(100)
   fmt.Println("Please input your guess")
   //reader := bufio.NewReader(os.Stdin)
   for {
      var guess int
      _,err := fmt.Scanf("%d",&guess)
      if err != nil{
         fmt.Println("An error occured while reading input. Please try again", err)
         continue
      }
      flag := doWork(guess,secretNumber)
      if flag{
         break
      }
   }
}

换成fmt.Scanf后代码整洁好多了，当然还有很多相应的Scanf知识点需要自己学习与提高。

2. 命令行词典

这个项目代码有点多，而且好多代码是相应的工具生成的，我先贴一下课程里完整的代码，然后在此基础上完成一个程序对另一种翻译引擎的支持。

2.1 完整代码

2.2 命令行词典作业

2.2.1 百度翻译词典

首先，我们进入百度翻译界面，然后打开开发者模式，点击下图的页面

3e47be0ec8eb4dbfb8960979ab7317df_tplv-k3u1fbpfcp-watermark.image

右键，然后找到Copy选项，然后再选择Copy as cURL(bash)选项，拷贝即可，然后再打开网站

d420c9b511cc476b88f0722cd5c13b96_tplv-k3u1fbpfcp-watermark.image

拷贝生成的代码，复制到编辑器。然后再打开百度翻译界面，打开开发者模式

16840a36c97841e7b4fa5bf4747e63a1_tplv-k3u1fbpfcp-watermark.image

复制里面的内容，然后再打开网站，将JSON转Golang Struct

!

3. 并发请求两个翻译引擎提高响应速度

上述，我们已经有两个程序分别是原有的（针对彩云科技翻译），现写的（百度翻译），我们在Go的main函数下可以启动两个线程，分别执行翻译，然后先得出结果的直接返回即可，这样可以提高响应速度，由于个人在Go并发方面没有深入学习，我就加了一个全局变量Num = 1，如果一个线程执行完毕，num减一，另一个线程如果发现num<1时，直接退出。这种方法局限性很高，不建议使用，待个人深入学习后，会加以改造。下面会我的代码：

package main

import (
   "bufio"
   "bytes"
   "encoding/json"
   "fmt"
   "io/ioutil"
   "log"
   "net/http"

   "strings"
)
var num = 1

         Source string      `json:"source"`
         Target interface{} `json:"target"`
      } `json:"description"`
      ID   string `json:"id"`
      Item struct {
         Source string `json:"source"`
         Target string `json:"target"`
      } `json:"item"`

   } `json:"wiki"`
   Dictionary struct {
      Prons struct {
         EnUs string `json:"en-us"`
         En   string `json:"en"`
      } `json:"prons"`
      Explanations []string      `json:"explanations"`
      Synonym      []string      `json:"synonym"`
      Antonym      []string      `json:"antonym"`
      WqxExample   [][]string    `json:"wqx_example"`
      Entry        string        `json:"entry"`
      Type         string        `json:"type"`
      Related      []interface{} `json:"related"`
      Source       string        `json:"source"`
   } `json:"dictionary"`
}

func query1(word string){
   client := &http.Client{}
   request := DictRequest{TransType: "en2zh", Source: word}
   buf, err := json.Marshal(request)
   if err != nil {
      log.Fatal(err)
   }
   var data = bytes.NewReader(buf)
   req, err := http.NewRequest("POST", "https://api.interpreter.caiyunai.com/v1/dict", data)
   if err != nil {
      log.Fatal(err)
   }
