Android使用httpPost向服务器发送请求的方法
本文实例讲述了Android使用httpPost向服务器发送请求的方法。分享给大家供大家参考，具体如下：
importjava.util.List;
importorg.apache.http.HttpEntity;
importorg.apache.http.HttpResponse;
importorg.apache.http.NameValuePair;
importorg.apache.http.client.HttpClient;
importorg.apache.http.client.entity.UrlEncodedFormEntity;
importorg.apache.http.client.methods.HttpPost;
importorg.apache.http.conn.ConnectTimeoutException;
importorg.apache.http.impl.client.DefaultHttpClient;
importorg.apache.http.params.CoreConnectionPNames;
importorg.apache.http.protocol.HTTP;
importorg.apache.http.util.EntityUtils;
importandroid.util.Log;
publicclassRequestByHttpPost{
publicstaticStringTIME_OUT="操作超时";
publicstaticStringdoPost(List<NameValuePair>params,Stringurl)throwsException{
Stringresult=null;
//新建HttpPost对象
HttpPosthttpPost=newHttpPost(url);
//设置字符集
HttpEntityentity=newUrlEncodedFormEntity(params,HTTP.UTF_8);
//设置参数实体
httpPost.setEntity(entity);
//获取HttpClient对象
HttpClienthttpClient=newDefaultHttpClient();
//连接超时
httpClient.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT,30000);
//请求超时
httpClient.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT,30000);
try{
//获取HttpResponse实例
HttpResponsehttpResp=httpClient.execute(httpPost);
//判断是够请求成功
if(httpResp.getStatusLine().getStatusCode()==200){
//获取返回的数据
result=EntityUtils.toString(httpResp.getEntity(),"UTF-8");
Log.i("HttpPost","HttpPost方式请求成功，返回数据如下：");
Log.i("result",result);
}else{
Log.i("HttpPost","HttpPost方式请求失败");
}
}catch(ConnectTimeoutExceptione){
result=TIME_OUT;
}
returnresult;
}
}
可以直接用的完整类。
希望本文所述对大家Android程序设计有所帮助。
