java代码调用http请求

 

首先生成一个请求对象
String url = "www.baidu.com";//设置url访问路径

HttpGet httpGet = new HttpGet(url);

//生成一个http客户端对象
HttpClient httpclient = new DefaultHttpClient();

InputStream inputStream = null;

try{
//使用http客户端发送请求对象
//客户端请求后，服务器端响应的结果
HttpResponse httpRespose = httpCient.execute(httpGet);
//httpEntity取出Response的内容
HttpEntity httpentity = httprespose.getEntity();
inputStream = httpentity.getcontent();
//从数据流中读取服务器端返回的值
BufferedRegder reader = new BufferedReader(new InputStreamReader(inputStream));
//定义字符串循环出reader内容
String result = "";
String line = "";
while((line= reader.readLine())!=null){
  result = result+line;
}
//打印服务器返回的内容
system.out.println(result);
}
catche(Exception e){
}
