android http 请求方式

android用 HttpClient向服务器发起GET或者POST请求：

首先client参数设置（可选设置，设置超时）：

private HttpClient httpclient;
private HttpPost httppost;
private HttpParams httpParameters;
private int timeoutConnection = 5*1000;
private int timeoutSocket = 10*1000;
public WidsetsHttpClient() {

          // Set the timeout in milliseconds until a connection is established.

httpParameters = new BasicHttpParams();

// Set the default socket timeout (SO_TIMEOUT) 

HttpConnectionParams.setConnectionTimeout(httpParameters, timeoutConnection);

// in milliseconds which is the timeout for waiting for data.

HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);

httpclient = new DefaultHttpClient(httpParameters);

httppost = new HttpPost(Display.serviceAPI);

}

1. GET：

//先将参数放入List，再对参数进行URL编码

List<BasicNameValuePair> params = new LinkedList<BasicNameValuePair>();

params.add(new BasicNameValuePair("param1", "value1"));

params.add(new BasicNameValuePair("param2", "value2"));

//对参数编码

String param = URLEncodedUtils.format(params, "UTF-8");

//请求的 地址Url

String baseUrl = "http://ubs.free4lab.com/php/method.php";

//将URL与参数拼接,拼地址

HttpGet getMethod = new HttpGet(baseUrl + "?" + param);

//默认参数

HttpClient httpClient = new DefaultHttpClient();

try {

    HttpResponse response = httpClient.execute(getMethod); //发起GET请求

//获取响应码返回200表示成功

    int resCode = response.getStatusLine().getStatusCode()

    Log.i(TAG, "resCode = " +resCode ); 

//获取服务器响应内容：字符串

    String result =  EntityUtils.toString(response.getEntity(), "utf-8");

    Log.i(TAG, "result = " + result ); 

} catch (ClientProtocolException e) {

    e.printStackTrace();

} catch (IOException e) {

    e.printStackTrace();

}

POST：

//和GET方式一样，先将参数放入List

params = new LinkedList<BasicNameValuePair>();

params.add(new BasicNameValuePair("param1", "value1"));

params.add(new BasicNameValuePair("param2", "value2"));

try {

    HttpPost postMethod = new HttpPost(baseUrl);

    postMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8")); //将参数填入POST Entity中

    HttpClient httpClient = new DefaultHttpClient();

    HttpResponse response = httpClient.execute(postMethod); //执行POST方法

//获取响应码返回200表示成功

    int resCode = response.getStatusLine().getStatusCode()

    Log.i(TAG, "resCode = " +resCode ); 

//获取服务器响应内容：字符串

    String result =  EntityUtils.toString(response.getEntity(), "utf-8");

    Log.i(TAG, "result = " + result ); 

} catch (UnsupportedEncodingException e) {

    e.printStackTrace();

} catch (ClientProtocolException e) {

    e.printStackTrace();

} catch (IOException e) {

    e.printStackTrace();
