android 端和服务器端的接口怎么设计

首先在服务器端，我采用的是SSH框架，struts 2集合了JSON插件，服务器和客户端的信息交互采用的JSON来传输，由于在服务器端用了Struts 2，所以我就用装了一个JSON插件。这样，很轻易的就把服务器端的信息用JSON的形式发送到了手机端。以下是代码：

首先，在服务器端搭建好SSH框架，具体细节就不在陈述。struts.xml配置如下：

<packagename="login"extends="json-default">

<actionname="login"class="com.jclick.test.LoginAction"method="login">

<resulttype="json"><paramname="includeProperties">result</param></result>

</action>

</package>

<packagename="login"extends="json-default">

<actionname="login"class="com.jclick.test.LoginAction"method="login">

<resulttype="json"><paramname="includeProperties">result</param></result>

</action>

</package>

手机端的代码如下：

中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。

关于获取天气预报的实例参考android学习手册，里面有源码。android学习手册包含9个章节，108个例子，源码文档随便看，例子都是可交互，可运行，源码采用android studio目录结构，高亮显示代码，文档都采用文档结构图显示，可以快速定位。360手机助手中下载,图标上有贝壳

中国国家气象局天气预报接口总共提供了三个：

http://www.weather.com.cn/data/sk/101010100.html

http://www.weather.com.cn/data/cityinfo/101010100.html

http://m.weather.com.cn/data/101010100.html

注：上面接口2014.3.4日已不再更新。换成这个：http://m.weather.com.cn/atad/101230201.html。各位看34楼。在此感谢tdwll和黄晓佳cobish。

最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。

在浏览器上输入url：http://m.weather.com.cn/data/101230101.html得到信息，天气信息是json的数据格式，数据如下：

{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}

我们可以解析json数据去得到自己想用的天气信息。

可使用android自带的httpclient框架，向后台发起请求，获取数据。\x0d\x0a\x0d\x0a1. GET 方式传递参数\x0d\x0a//先将参数放入List，再对参数进行URL编码\x0d\x0aList params = new LinkedList()\x0d\x0aparams.add(new BasicNameValuePair("param1", "数据")) //增加参数1\x0d\x0aparams.add(new BasicNameValuePair("param2", "value2"))//增加参数2\x0d\x0aString param = URLEncodedUtils.format(params, "UTF-8")//对参数编码\x0d\x0aString baseUrl = "服务器接口完整URL"\x0d\x0aHttpGet getMethod = new HttpGet(baseUrl + "?" + param)//将URL与参数拼接\x0d\x0aHttpClient httpClient = new DefaultHttpClient()\x0d\x0atry {\x0d\x0aHttpResponse response = httpClient.execute(getMethod)//发起GET请求\x0d\x0aLog.i(TAG, "resCode = " + response.getStatusLine().getStatusCode())//获取响应码\x0d\x0aLog.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"))//获取服务器响应内容\x0d\x0a} catch (ClientProtocolException e) {\x0d\x0ae.printStackTrace()\x0d\x0a} catch (IOException e) {\x0d\x0ae.printStackTrace()\x0d\x0a}\x0d\x0a\x0d\x0a2. POST方式 方式传递参数\x0d\x0a//和GET方式一样，先将参数放入List\x0d\x0aparams = new LinkedList()\x0d\x0aparams.add(new BasicNameValuePair("param1", "Post方法"))//增加参数1\x0d\x0aparams.add(new BasicNameValuePair("param2", "第二个参数"))//增加参数2\x0d\x0atry {\x0d\x0aHttpPost postMethod = new HttpPost(baseUrl)//创建一个post请求\x0d\x0apostMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8"))//将参数填入POST Entity中\x0d\x0aHttpResponse response = httpClient.execute(postMethod)//执行POST方法\x0d\x0aLog.i(TAG, "resCode = " + response.getStatusLine().getStatusCode())//获取响应码\x0d\x0aLog.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"))//获取响应内容\x0d\x0a} catch (UnsupportedEncodingException e) {\x0d\x0ae.printStackTrace()\x0d\x0a} catch (ClientProtocolException e) {\x0d\x0ae.printStackTrace()\x0d\x0a} catch (IOException e) {\x0d\x0ae.printStackTrace()\x0d\x0a}
