本文介紹了django實現前后臺交互實例，分享給大家，希望對大家有所幫助
準備工作：
前端框架：AngularJS+bootstap
數據庫：sqlite3
前端代碼：
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="請輸入用戶名" ng-model="username"> </div> </td> </tr> <tr> <td> <div class="form-group"> <input type="passwd" class="form-control" id="name" placeholder="請輸入密碼" 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) { $http({ method: 'POST', url: '/do_save_info', data: { 'username': username, 'password': password }, headers: {'Content-Type': undefined}, }).success(function(response){ callback(response); }); }; }]); 后端代碼：
urls.py
from django.conf.urls import patterns, include, url urlpatterns = patterns('app.views', url(r'^index$', '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表結構：
create table t_user(username varchar(255), password varchar(255));
頁面演示：
剛打開頁面如下：
輸入數據，點擊保存：
后臺查看數據庫：
可以看到，已經保存在數據庫里面了。
這只是個小示例，在此不考慮頁面排版和安全性問題。。。
