WebApp简单制作(后端也可以装逼啦)

前端越来越吃香的感觉

  年后回来,跟之前和几个同事和朋友聊天,发现有两个.net的和一个php的朋友都转到了前端,真是出乎意料。自从之前的webapp兴起后,前端感觉比后端吃香很多,总结朋友们转的原因,大概就几点

1.易上手,相对其他语言来说,作为后端人员,转到前端,其实已经有了很好的底子和基础了,毕竟以前多少都会和js,jq,html,css打交道

2.前端比后端容易找工作,这里的容易找工作,是指不会被后端的语言限死。就像我朋友说的“做网站不一样需要.net,可以是java,可以是php,但一定离不开js,jq,html,css这些东西”。

3.前端妹子多......

   其实自己也觉得有一定道理,感觉这两年.net的需求度相对其他的语言都弱了些,前程上搜索发现,.net的职位数是1100+,php是1800+, 前端是2000+,java 是3600+(都是仅限于广州)。所以还是蛮明显的。

   看到了那么多朋友转前端,自己也开始搞点前端的东西,近期刚好有点时间,正好研究下webapp开发, 其实webapp开发说到底就是响应式布局嘛,配合html5+css3就看上去高大上点了。不过作为后端程序猿来说,我还没打算深入去研究html5和css3,反正就是响应式布局,用现成的前端框架来练练手。于是,就想用bootstrap做一个简单的新闻网站来装下逼。

 初试

  Boootstrap,来自 Twitter,是目前很受欢迎的前端框架,主要是响应式布局,无论是文档,资料,还是demo等都比较齐全,而且界面好看,提供多样式主题,还有很多开源的插件和模板,上手相对简单,让后端程序屌丝也能做出好看的界面。

 文件的下载和相关引用,可参考如下地址,详细明了

 http://v3.bootcss.com/getting-started/

 就是下载后只要依次引入:

bootstrap.min.css

bootstrap-theme.min.css

Jquery.min.js

Bootstrap.min.js

这四个文件就好了,然后 在<head> 之中添加 viewport 元数据标签,用来指定移动设备优先

<meta name="viewport" content="width=device-width, initial-scale=1">
viewport

登陆,注册

使用到的组件 panel(面板),navbar(导航条),from(表单) jNotify(提示框)

 

表单验证,Bootstrap下的表单本身不带验证功能,不过它的插件很多,表单插件bootstrapvalidator就是其中一款,感觉它封装的验证功能比easyui的还要强大。

 下载地址: https://github.com/nghuuphuoc/bootstrapvalidator

 使用方式,引入 bootstrapValidator.min.css  和  bootstrapValidator.min.js

 这两个文件,然后初始化表单

Bootstrapvalidator下载的代码中有大量的demo,可以根据需要自己选择查看。

 

提示框,jNotify

jNotify是一款提示消息的插件,不过它并不是Bootstrap专有的插件。它提示界面好看,而已又是属于轻量级的,方法使用也简单,下载地址:http://www.jq22.com/jquery-info1377

 使用方式,引入  jNotify.jquery.js  和  jNotify.jquery.css

这两个文件,然后就可以直接使用

jError("错误信息提示");

jSuccess("成功信息提示");

jNotify("一般信息提示");

 造数据

前端基本搭建好了,一个简单的新闻浏览页面就出来了,接着就是让后端有数据出来,怎么办呢,自己写一个后台,提供新闻发布功能,然后自己来造数据?不不不,难得搞定了前端,后端就更要装逼点,直接找个网站偷点数据就好了。于是乎浏览了网易新闻,用谷歌查看了它的请求,发现比想象中的简单很多:

 网易网页:

http://3g.163.com

 新闻列表的获取地址(地址A):

http://3g.163.com/touch/article/list/BBM54PGAwangning/0-10.html

http://3g.163.com/touch/article/list/{类型标示}/{页码}-{页数}.html

新闻详情页面的获取地址:

http://3g.163.com/touch/article/BI0GG89900014AED/full.html

http://3g.163.com/touch/article/{地址A中返回的新闻标示}/full.html

 哈哈,就是这么简单了,写个控制台跑一下,把新闻标题,图片,内容等信息全部拿下来保存到本地,发送给前端显示就好了,于是就有了下面代码:

  1  public class NewsHelper
  2     {
  3         //获取新闻列表
  4         public static List<NewsItem> GetNews(KeyValuePair<NewTypeEnum, string> newType)
  5         {
  6             string type = newType.Value;
  7             int pageIndex = 0;
  8             int pageSize = 10;
  9             bool isStart = true;
 10             while (isStart)
 11             {
 12                 List<NewsItem> newsInfos = new List<NewsItem>();
 13                 string url = string.Format("http://3g.163.com/touch/article/list/{0}/{1}-{2}.html", type, pageIndex * pageSize, pageSize);
 14                 string result = HttpHelper.Get(url);
 15                 Console.WriteLine(string.Format("{0}  行位置:{1}", type, pageIndex * pageSize));
 16                 if (!string.IsNullOrWhiteSpace(result))
 17                 {
 18                     result = result.Replace("artiList(", "").Trim(')');
 19                     if (!string.IsNullOrWhiteSpace(result))
 20                     {

 23

装逼升级

用户是最懒的,你让用户在手机上自己输入一个网站的地址来使用你的webapp,用户会打你的。所以对用户来讲,手机上我想的是一安装,然后打开就能用了。那无非就是搞了app,什么功能都不用,内置一个浏览器,一开到就直接在这个app上面跳到你的网站就好了。就像winfrom里面的webBrowser一样。于是百度了一下,android有WebView 这一控件,可以实现这样功能,虽然不懂安卓,不过这个小功能还是简单的,于是百度WebView 的使用,大致过程如下:

 

先建一个空白的android项目

在AndroidManifest.xml设置访问网络权限:

<uses-permission android:name="android.permission.INTERNET"/>
View Code

然后修改MainActivity,如下:

 1 private WebView webView;
 2     @Override
 3     protected void onCreate(Bundle savedInstanceState) {
 4         super.onCreate(savedInstanceState);
 5         setContentView(R.layout.main);             
 6         init();
 7 
 8     }
 9     
10     private void init(){
11         webView = (WebView) findViewById(R.id.webView);
12         webView.loadUrl("http://192.168.0.102:1111/");
13         WebSettings settings = webView.getSettings();
14         settings.setJavaScriptEnabled(true);
15         
16         webView.setWebViewClient(new WebViewClient(){
17            @Override
18          public boolean shouldOverrideUrlLoading(WebView view, String url) {
19              view.loadUrl(url);
20             return true;
21         }
22        });
23     }
View Code

 对,就是这么简单(太难的我也不会O(∩_∩)O),然后生成apk安装包,安装后在手机上直接打开后如下:

 

好了,这逼装完了,最后,说那么多不分享源码的都是流氓,源码如下:

后面有时间学习下node.js,希望有博友有好的博客能推荐下,一起学习,一起分享。
