本文介绍了django实现前后台交互实例，分享给大家，希望对大家有所帮助

准备工作：

前端框架：AngularJS+bootstap

数据库：sqlite3

前端代码：
index.html

<!DOCTYPE html> 
<html> 
  <head> 
    <link href="/WebApi/scripts/bootstrap/dist/css/bootstrap.min.css" rel="external nofollow" rel="stylesheet" type="text/css" /> 
    <script type="text/javascript" src="/WebApi/scripts/angular/angular.min.js"></script> 
    <script type="text/javascript" src="/WebApi/controller/controller.js"></script> 
    <script type="text/javascript" src="/WebApi/service/service.js"></script> 
    <title>hello</title> 
  </head> 
  <body ng-app="myApp" ng-controller="myCtrl"> 
    <h2>hello world!</h2> 
     
<!--   <form role="form"> --> 
    <table> 
      <tr> 
        <td> 
          <div class="form-group"> 
            <input type="text" class="form-control" id="name"  
          placeholder="请输入用户名" ng-model="username"> 
          </div> 
        </td> 
      </tr> 
      <tr> 
        <td> 
          <div class="form-group"> 
            <input type="passwd" class="form-control" id="name"  
          placeholder="请输入密码" ng-model="password"> 
          </div> 
        </td> 
      </tr> 
      <tr> 
        <td> 
          <button type="button" class="btn btn-primary" ng-click="my_submit()">保存</button> 
        </td> 
      </tr> 
    </table> 
<!--   </form> 
 --> 
 
    <p class="text-danger">[[ result ]]</p> 
  </body> 
</html>

controller.js

var app = angular.module("myApp",[]); 
app.config( 
  function($interpolateProvider) { 
    $interpolateProvider.startSymbol('[['); 
    $interpolateProvider.endSymbol(']]'); 
  })  
  .config(['$httpProvider',function($httpProvider) { 
    $httpProvider.defaults.xsrfCookieName = 'csrftoken'; 
    $httpProvider.defaults.xsrfHeaderName = 'X-CSRFToken'; 
}]); 
app.controller("myCtrl",["$scope","service",function($scope,service) { 
  $scope.result = ""; 
  $scope.my_submit = function() { 
    console.log($scope.username); 
    console.log($scope.password); 
    service.do_save_info($scope.username,$scope.password,function(response){ 
      console.log(response); 
      $scope.result = response.result; 
    }); 
  }; 
}]);

service.js

app.service("service",["$http",function($http) { 
  this.do_save_info = function(username,password,callback) { 
    $http({ 
      method: 'POST',url: '/do_save_info',data: { 
        'username': username,'password': password 
      },headers: {'Content-Type': undefined},}).success(function(response){ 
      callback(response); 
    }); 
  }; 
}]);

后端代码：

urls.py

from django.conf.urls import patterns,include,url 
 
urlpatterns = patterns('app.views',url(r'^index$','index'),url(r'^/index$',url(r'^$',url(r'^/$',url(r'^do_save_info$','do_save_info'),)

views.py

from django.shortcuts import render_to_response 
from django.template import RequestContext 
from django.http import HttpResponse 
from django.views.decorators.csrf import ensure_csrf_cookie,csrf_exempt 
import json 
import models 
 
# Create your views here. 
@ensure_csrf_cookie 
def index(request): 
  return render_to_response('static/index.html',context_instance=RequestContext(request)) 
 
def do_save_info(request): 
  result = {'result':'save success'} 
  try: 
    data = json.loads(request.body) 
    username = data.get("username",None) 
    password = data.get("password",None) 
    models.do_save_info(username,password) 
  except Exception,e: 
    result['result'] = 'save error' 
  return HttpResponse(json.dumps(result))

models.py

#!/bin/python 
# -*- coding: utf-8 -*- 
 
import os 
import sys 
import sqlite3 
 
def do_save_info(username,password): 
  db_path = os.path.normpath('/home/zhubao/Code/django_code/hello/db.sqlite3') 
  try: 
    conn = sqlite3.connect(db_path) 
    sql = "insert into t_user(username,password) values('%s','%s')" % (username,password) 
    conn.execute(sql) 
    conn.commit() 
    conn.close() 
    print 'save success...' 
  except Exception,e: 
    print '------',str(e) 
    try: 
      conn.close() 
    except Exception,e: 
      pass

t_user表结构：

create table t_user(username varchar(255),password varchar(255));

页面演示：

刚打开页面如下：

输入数据，点击保存：

后台查看数据库：

可以看到，已经保存在数据库里面了。

这只是个小示例，在此不考虑页面排版和安全性问题。。。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持编程小技巧。
