django实现前后台交互实例

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

 
 
   
     
     
     
     
     
   
   
    
hello world!
 
     
 
    
 
      
 
        
 
          
 
             
          
 
        
 
      
 
      
 
        
 
          
 
             
          
 
        
 
      
 
      
 
        
 
          保存 
        
 
      
 
    
 
 
 
    
[[ result ]]
 
   
 

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$', 'index'), 
  url(r'^/index$', 'index'), 
  url(r'^$', 'index'), 
  url(r'^/$', 'index'), 
  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。。。
