首先找到之前做完的nodejs-text,文件如果沒(méi)有的話可以去我的git倉(cāng)庫(kù)里下載
當(dāng)然我的倉(cāng)庫(kù)里是已經(jīng)修改完的门坷。 (￣y▽￣)~*
首先我們需要在sever.js文件里面添加上我們的注冊(cè)頁(yè)面

else if (path === '/sign_up' ) {
    let string = fs.readFileSync('./sign_up', 'utf8')
    response.statusCode = 200
    response.setHeader('Content-Type', 'text/html;charset=utf-8')
    response.write(string)
    response.end()

添加此代碼讓我們可以通過(guò)/sign_up鏈接到我們的注冊(cè)頁(yè)面调鲸，有了鏈接的地方那么我們就需要準(zhǔn)備我們的注冊(cè)頁(yè)面了撒强，
注冊(cè)頁(yè)面

<script>
        let $form = $('#signUpForm')
        $form.on('submit',(e)=>{
            
            let=hash{}
            e.preventDefault()
            let need=['email','password','password_confirmation']
            need.forEach((name)=>{
                let value = $form.find('[name=${name}]').val()
                hash[name]=value

            })
/*下面代碼用于清空無(wú)效的提示*/
            $form.find('.error').each((index,span)=>{
                $(span).text('')
            })
/*通過(guò)一下代碼告知用戶輸入郵箱和密碼是否有錯(cuò)誤*/
            if(hash['email']=== ''){
                $form.find('[name="email"]').siblings('.error')
                .text('請(qǐng)?zhí)顚?xiě)郵箱')
                return
            }
            if(hash['password']=== ''){
                $form.find('[name="password"]').siblings('.error')
                .text('請(qǐng)?zhí)顚?xiě)密碼')
                return
            }
            if(hash['password_confirmation']=== ''){
                $form.find('[name="password_confirmation"]').siblings('.error')
                .text('請(qǐng)確認(rèn)密碼')
                return
            }
            if(hash['password'] !==hash['password_confirmation']){
                $form.find('[name="password_confirmation"]').siblings('.error')
                .text('密碼不匹配')
                return
            }
            $.post('/sign_up',hash)
            .then(()=>{
                console.log('success')
            },(requrst)=>{
                let {error} = requrst.responseJSON
                if(errors.email && errors.email === 'invalid'){
                    $form.find('[name="email"]').siblings('.error')
                    .text('郵箱格式錯(cuò)誤')
                }
            })
        })
/*到此結(jié)束*/
    </script>

在server.js文件中添加
if else循環(huán)中添加一下代碼作為判定條件

else if (path === '/sign_up' && method === 'GET') {
    let string = fs.readFileSync('./sign_up', 'utf8')
    response.statusCode = 200
    response.setHeader('Content-Type', 'text/html;charset=utf-8')
    response.write(string)
    response.end()
  } else if (path === '/sign_up' && method === 'POST') {
    readBody(request).then((body)=>{
      let strings=body.split('&')
      let hash ={}
      strings.forEach((string)=>{
        let parts=string.split('=')
        let key = parts[0]
        let value = parts[1]
        hash[key] = value
    })
      let {email,password,password_confirmation}= hash
      if(email.indexOf('@') === -1){
        response.statusCode = 400
        response.setHeader('Content-Type', 'application/json;charset=utf-8')
        response.write(`{
          "errors":{
            "email":"invalid"
          }
        }`)
      }else if(password !== password_confirmation){
        response.write('password not match')
      }else{
        response.statusCode = 200
      }
      
      response.end()
    });

  }

在下方新建函數(shù)

function readBody(request){
  return new Promise((resolve,reject)=>{
    let body=[]
    request.on('data')
    request.on('data', (chunk) => {
      body.push(chunk);
    }).on('end', () => {
      body = Buffer.concat(body).toString();
      resolve(body)
    });
  })
}

讓我們可以獲得有格式的用戶注冊(cè)數(shù)據(jù)
