=============

Android?SDK集成了Apache?HttpClient模塊。要注意的是，這里的Apache?HttpClient模塊是 HttpClient?4.0（org.apache.http.*），而不是常見的 Jakarta?Commons?HttpClient?3.x（org.apache.commons.httpclient.*）。

?????????? HttpClient常用HttpGet和HttpPost這兩個(gè)類，分別對應(yīng)Get方式和Post方式。

?????????? 無論是使用 HttpGet ，還是使用 HttpPost ，都必須通過如下 3 步來訪問 HTTP 資源。

?????????? 1. 創(chuàng)建 HttpGet 或 HttpPost 對象，將要請求的 URL 通過構(gòu)造方法傳入 HttpGet 或 HttpPost 對象。

???????? ? 2. 使用 DefaultHttpClient 類的 execute 方法發(fā)送 HTTP?GET 或 HTTP?POST 請求，并返回 HttpResponse 對象。

?????????? 3. 通過 HttpResponse 接口的 getEntity 方法返回響應(yīng)信息，并進(jìn)行相應(yīng)的處理。

?????????? 如果使用 HttpPost 方法提交 HTTP?POST 請求，則需要使用 HttpPost 類的 setEntity 方法設(shè)置請求參數(shù)。參數(shù)則必須用NameValuePair[]數(shù)組存儲(chǔ)。

??????????

???????? ?? HttpGet

[java] view plain copy

//??????HttpGet?httpRequst?=?new?HttpGet(String?uri); ??
//??????創(chuàng)建HttpGet或HttpPost對象，將要請求的URL通過構(gòu)造方法傳入HttpGet或HttpPost對象。 ??
????????HttpGet?httpRequst?=? new ?HttpGet(uriAPI);??
??
//??????new?DefaultHttpClient().execute(HttpUriRequst?requst); ??
???????? try ?{??
??? //使用DefaultHttpClient類的execute方法發(fā)送HTTP?GET請求，并返回HttpResponse對象。 ??
????????????HttpResponse?httpResponse?=? new ?DefaultHttpClient().execute(httpRequst); //其中HttpGet是HttpUriRequst的子類 ??

????????????? ? HttpPost

????????????? 如果使用 HttpPost 方法提交 HTTP?POST 請求，則需要使用 HttpPost 類的 setEntity 方法設(shè)置請求參數(shù)。參數(shù)則必須用NameValuePair[]數(shù)組存儲(chǔ)。

[java] view plain copy

public ?String?doPost()??
????{??
????????String?uriAPI?=? "http://XXXXXX" ;//Post方式?jīng)]有參數(shù)在這里??
????????String?result?=? "" ;??
????????HttpPost?httpRequst?=? new ?HttpPost(uriAPI); //創(chuàng)建HttpPost對象 ??
??????????
????????List?<NameValuePair>?params?=? new ?ArrayList<NameValuePair>();??
????????params.add( new ?BasicNameValuePair( "str" ,? "I?am?Post?String" ));??
??????????
???????? try ?{??
????????????httpRequst.setEntity( new ?UrlEncodedFormEntity(params,HTTP.UTF_8));??
????????????HttpResponse?httpResponse?=? new ?DefaultHttpClient().execute(httpRequst);??
???????????? if (httpResponse.getStatusLine().getStatusCode()?==? 200 )??
????????????{??
????????????????HttpEntity?httpEntity?=?httpResponse.getEntity();??
????????????????result?=?EntityUtils.toString(httpEntity); //取出應(yīng)答字符串 ??
????????????}??
????????}? catch ?(UnsupportedEncodingException?e)?{??
???????????? //?TODO?Auto-generated?catch?block ??
????????????e.printStackTrace();??
????????????result?=?e.getMessage().toString();??
????????}??
???????? catch ?(ClientProtocolException?e)?{??
???????????? //?TODO?Auto-generated?catch?block ??
????????????e.printStackTrace();??
????????????result?=?e.getMessage().toString();??
????????}??
???????? catch ?(IOException?e)?{??
???????????? //?TODO?Auto-generated?catch?block ??
????????????e.printStackTrace();??
????????????result?=?e.getMessage().toString();??
????????}??
???????? return ?result;??
????}??

????????? 以發(fā)送連接請求時(shí)，需要設(shè)置鏈接超時(shí)和請求超時(shí)等參數(shù)，否則會(huì)長期停止或者崩潰。

[java] view plain copy

HttpParams?httpParameters?=? new ?BasicHttpParams();??
HttpConnectionParams.setConnectionTimeout(httpParameters,? 10 * 1000 ); //設(shè)置請求超時(shí)10秒 ??
HttpConnectionParams.setSoTimeout(httpParameters,? 10 * 1000 );? //設(shè)置等待數(shù)據(jù)超時(shí)10秒 ??
HttpConnectionParams.setSocketBufferSize(params,? 8192 );??
HttpClient?httpclient?=? new ?DefaultHttpClient(httpParameters);? //此時(shí)構(gòu)造DefaultHttpClient時(shí)將參數(shù)傳入 ??
??
