HttpClient中的HttpGet和HttpPost请求方式
| HttpClientapache 发布,模拟一个浏览器 步骤： |
| 1.打开浏览器 HttpClient client = new DefaultHttpClient() 2.输入一些内容 HttpGet 3.敲回车 client.execute(path); |
| 1、HttpGet /**
* 1、使用HttpClient——GET方式进行登录
*
* @throws IOException
*/
public static String loginByGet(String username, String password)throws IOException {
System.out.println("以GET方式提交。。。");
// 1、打开一个浏览器
HttpClient client = new DefaultHttpClient(); String path = "http://192.168.221.221:8080/web/LoginServlet?username="
+ username + "&password" + password;
// 2、输入url地址
HttpGet httpGet = new HttpGet(path); // 3、敲回车
HttpResponse response = client.execute(httpGet); int code = response.getStatusLine().getStatusCode();
if (code == 200) {
// 数据实体
HttpEntity entity = response.getEntity();
InputStream in = entity.getContent();
String text = StreamUtils.readStream(in);
return text;
}
return null;
} |

2、HttpPost
/**
* 2、使用HttpClient——POST方式登录
*
* @param username
* @param password
* @return
* @throws IOException
*/
public static String loginByPost(String username, String password)
throws IOException {
System.out.println("以POST方式登录。。。"); String path = "http://192.168.221.221:8080/web/LoginServlet";
// 1、打开一个浏览器 HttpClient client = new DefaultHttpClient();
// 2、输入url地址 HttpPost httpPost = new HttpPost(path); // 3、设置请求内容
List<NameValuePair> parameters = new ArrayList<NameValuePair>();
parameters.add(new BasicNameValuePair("username", username));
parameters.add(new BasicNameValuePair("password", password));
HttpEntity entity = new UrlEncodedFormEntity(parameters, "UTF-8");
// 对请求参数进行编码：encoding the name/value pairs be encoded with
httpPost.setEntity(entity);
// 4、敲回车
HttpResponse response = client.execute(httpPost);
int code = response.getStatusLine().getStatusCode(); // 服务器状态码
if (code == 200) {
InputStream in = response.getEntity().getContent();
String text = StreamUtils.readStream(in);
return text;
}
return null;
}
