public class

HttpGet

extends HttpRequestBase

java.lang.Object

   ↳
org.apache.http.message.AbstractHttpMessage

   ↳
org.apache.http.client.methods.HttpRequestBase

   ↳

使用步骤：

Post:    1、    声明实例化HttpPost              HttpPost  httpRequest=new HttpPost(URI)

           2、  用NameValuePair[]数组储存Post要运行的变量 

              List<NameValuePair > parms=new ArrayList<NameValuePair>            

              parms.add(new BasicNameValuePair(“str”,"I am Post String”));

             3、发出httpRequest  

       httprequest.setEntity(new UrlEncodedFormEntity(parms, HTTP.UTF_8));

          4、返回httprespose
       HttpResponse httpresponse=new DefaultHttpClient().execute(httprequest);

          5、根据实际网络反馈 情况反映信息 取出httpResponse的信息

       if(httpResponse.getStatusLine().getStatusCode()==200)

                  String strResult=EntityUtils.toString(httpresponse.getEntity());

 

Get          

1、实例化HttpGet  

       HttpGet httpRequest =new HttpGet(Uri);

2、返回httpResponse

    HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);

3、

根据实际网络反馈 情况反映信息 取出httpResponse的信息

       if(httpResponse.getStatusLine().getStatusCode()==200)

                  String strResult=EntityUtils.toString(httpresponse.getEntity());

                  strResult = eregi_replace("(\r\n|\r|\n|\n\r)","",strResult);

              public String eregi_replace(String strFrom, String strTo, String strTarget)
            {
                                  String strPattern = "(?i)"+strFrom;
                                  Pattern p = Pattern.compile(strPattern);
                                 Matcher m = p.matcher(strTarget);
                                  if(m.find())
                                {
                                   return strTarget.replaceAll(strFrom, strTo);
                                   }
                                     else
                                  {
                                      return strTarget;
                                    }
                   }
