本文主要介紹了Django 登錄注冊的實(shí)現(xiàn)示例,這是做網(wǎng)頁登錄和注冊基本上都是必要一步,具有一定的參考價(jià)值,感興趣的可以了解一下

最近在準(zhǔn)備上線一個(gè)網(wǎng)站（基于django的編程技術(shù)學(xué)習(xí)與外包服務(wù)網(wǎng)站），所以會將自己的在做這個(gè)項(xiàng)目的過程中遇到的模塊業(yè)務(wù)以及所涉及到的部分技術(shù)記錄在CSDN平臺里，一是希望可以幫到有需要的同學(xué)，二十以供自己后續(xù)回顧學(xué)習(xí)。

今天要分享的是django的登錄和注冊頁面功能，其實(shí)做網(wǎng)頁登錄和注冊基本上都是必要的一步啦，那么今天我們就來了解一下。

登錄注冊前端Html以及Css我就不細(xì)說啦，畢竟我主要是負(fù)責(zé)后端業(yè)務(wù)的，再說即使你我不會前端的內(nèi)容，網(wǎng)上一大堆的登錄注冊的模板，直接拿來下載就好了，我這個(gè)登陸注冊的前端模板就是直接在網(wǎng)站上Copy的，另外說到這個(gè)登錄注冊一般有兩種情況（1：登錄為一個(gè)頁面，注冊為一個(gè)頁面，2：登錄注冊同是在一個(gè)頁面）。

我先說一下在django框架里我們實(shí)現(xiàn)登錄注冊的一個(gè)大概流程：

拿到前端的模板，我們更據(jù)需要建立對應(yīng)的數(shù)據(jù)庫里的字段，然后回來前端來看，比如說我們點(diǎn)擊注冊，那么我們把注冊的按鈕的類型設(shè)置為submit，給每一個(gè)注冊頁面的輸入框設(shè)置一個(gè)name屬性，然后回到后端來看，在后端里，我們在函數(shù)中需要寫入判斷函數(shù)，如果是GET方法則返回注冊頁面，如果是POST方法（submit即提交表單），我們則會獲取我們輸入框的信息，然后我們將其存放在數(shù)據(jù)庫里即可，同時(shí)回到登錄頁面，然后輸入框輸入對應(yīng)的信息，如果輸入的信息（賬號和密碼）存在在數(shù)據(jù)庫里，則信息正確進(jìn)入我們的首頁（指定頁面）。

前端頁面如下：

自定義404報(bào)錯(cuò)頁面：

    back.onclick = function(e){

后端業(yè)務(wù)處理代碼如下：

def login(request):
    if request.method == "GET":
        return render(request,'login.html')
    elif request.POST.get('registersubmit'):
        print('nihao 注冊')
        name = request.POST.get('name')
        account = request.POST.get('account')
        password = request.POST.get('password')
        checkpassword = request.POST.get('password_confirmation')
        try:
            User.objects.get(account=account)
        except:
            if not name or not account or not password or not checkpassword:
                return errorResponse(request, '定義技術(shù)：昵稱or賬號or密碼存在空值')
            if password != checkpassword:
                return errorResponse(request, '定義技術(shù)：兩次密碼不吻合')
            User.objects.create(name=name, account=account, password=password, checkpassword=checkpassword)
        return render(request,"login.html")
    elif request.POST.get('loginsubmit'):
        print('nihao 登錄')
        account1 = request.POST.get('account')
        password1 = request.POST.get('password')
        try:
            User.objects.get(account=account1,password=password1)
        except:
            return errorResponse(request,'定義技術(shù)：輸入信息有誤')

數(shù)據(jù)庫：

from django.db import models
class User(models.Model):
    name=models.CharField(verbose_name='昵稱',max_length=30)
    account=models.CharField(verbose_name='賬號',max_length=30)
    password=models.CharField(verbose_name='密碼',max_length=30)
    checkpassword=models.CharField(verbose_name='確認(rèn)密碼',max_length=30)
