android的http请求get和post请求方式

一、Get请求

HttpClient介绍

HttpClient是用来模拟HTTP请求的，其实实质就是把HTTP请求模拟后发给Web服务器；

Android已经集成了HttpClient，因此可以直接使用；

注：此处HttpClient代码不只可以适用于Android，也可适用于一般的Java程序；

1.获取界面的请求参数

private HttpReaponse httpReaponse = null;

private HttpEntity httpEntity = null;

String name = nameView.getText().toString();

String age = ageView.getText().toString();

2.组装请求参数

String url = baseUrl + "?" +"name=" + name + "&age=" + age;

3.生成一个Get请求对象

HttpGet httpGet = new HttpGet(url);

4.生成Http客户端对象

HttpClient httpClient = new DefaultHttpClient();

4.使用Http客户端发送请求

//用来保存返回来的数据

InputStream inputStream = null;

try{

//模拟发送请求

httpResponse = httpClient.execute(httpGet);

//获取返回Entity 

httpEntity = httpResponse.getEntity();

//获取返回内容

inputStream = heepEntity.getContent();

//读取返回内容

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

String result = "";

String line = "";

while((line = reader.readLine()) != null){

result = result + line;

}catch (Exception e){

e.printStackTrace();

}

finally{

try{

inputStream.close();

}catch (Exception e)

{

e.printStackTrace();

}

}

}

二、Post请求

String name = nameView.getText().toString();

String age = ageView.getText().toString();

//把参数放到NameValuePair 里面以键值对的形式存在

NameValuePair  valuea = new NameValuePair("name",name);  

NameValuePair  valueb = new NameValuePair("age",age);

//把参数加入到List集合当中

List<NameValuePair> list = new ArrayList<NameValuePair>();

list.add(valuea);

list.add(valueb);

try{

//进行编码

HttpEntity requestHttpEntity = new UrlEncodeedFormEntity(list);

//生成Post请求对象

HttpPost httpPost = new HttpPost(baseUrl);

httpPost.setEntity(requestHttpEntity);

//生成http客户端对象

HttpClient httpClient = new DefaultHttpClient();

InputStream inputStream = null;

try{

httpResponse = httpClient.excute(httpPost);

//获取返回Entity 

httpEntity = httpResponse.getEntity();

//获取返回内容

inputStream = heepEntity.getContent();

//读取返回内容

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));

String result = "";

String line = "";

while((line = reader.readLine()) != null){

result = result + line;

}catch (Exception e){

e.printStackTrace();

}

finally{

try{

inputStream.close();

}catch (Exception e)

{

e.printStackTrace();

}

}

}

catch (Exception e)

{

e.printStackTrace();

}
