Android关于GET和ＰＯＳＴ发送请求

在使用Post 发送请求时，注意有一个接口org.apache.http.NameValuePair , 它有一个实现类BasicNameValuePair

一种写法是NameValuePairt namevaluePair = new BasicNameValuePair("name", name);

HttpEntity requestHttpEntity = new UrlEncodedFormEntity(namevaluePair);

HttpEntity 类既可以作为发送请求的请求体, 也可以作为接收响应的响应体, 这里由于是发送Post 请求，因此定义为requestHttpEntity

下面将Get,Post 请求流程示例代码列出：

/**
* 使用 Get 发送请求
*/
HttpEntity httpEntity = null;
HttpResponse res = null;
String baseUrl = "http://192.168.1.100:8081/serverside/name";

String name = nameView.getText().toString();
String age = ageView.getText().toString();
String url = baseUrl + "?name="+name+"&age=" + age;
// 创建一个get请求对象
HttpGet httpGet = new HttpGet(url);
// 创建一个Http客户端对象
HttpClient httpClient = new DefaultHttpClient();
InputStream is = null;
try{
res = httpClient.execute(httpGet);
httpEntity = res.getEntity();
is = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
String result = "";
String line = "";
while(null != (line= reader.readLine())){
result = result + line;
}
}catch(Exception e){}

/**
* 使用 Post 发送请求
*/
HttpEntity httpEntity = null;
HttpResponse res = null;
String baseUrl = "http://192.168.1.100:8081/serverside/name";

String name = nameView.getText().toString();
String age = ageView.getText().toString();
//创建键值对对象
NameValuePair namePair = new BasicNameValuePair("name", name);
NameValuePair agePair = new BasicNameValuePair("age", age);
List<NameValuePair> pairList = new ArrayList<NameValuePair>();
pairList.add(namePair);
pairList.add(agePair);

try{

HttpEntity requesthttpEntity = new UrlEncodedFormatEntity(pairList);
// 创建一个post请求对象
HttpPost httpPost = new HttpPost(baseUrl);
httpPost.setEntity(requesthttpEntity);
// 创建一个Http客户端对象
HttpClient httpClient = new DefaultHttpClient();
InputStream is = null;

res = httpClient.execute(httpPost);
httpEntity = res.getEntity();
is = httpEntity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
String result = "";
String line = "";
while(null != (line= reader.readLine())){
result = result + line;
}

}catch(Exception e){}finally{
if (null != is)
{
is.close();
}
}
