HttpClient发起GETPOST请求

在工作线程中进行此操作：

GET请求：

public String loginOfGet(String username, String password) { HttpClient client = null; try { // 定义客户端对象 client = new DefaultHttpClient(); // 声明Get方法 String uri = "http://xxx?"; String data = "username=" + username + "&password=" + password; HttpGet get = new HttpGet(uri + data); // 使用客户端执行Get方法 HttpResponse response = client.execute(get); // 获得响应码，处理服务器返回的数据 int stateCode = response.getStatusLine().getStatusCode(); if (200 == stateCode) { InputStream is = response.getEntity().getContent(); // 解析服务器返回的数据 String result = getStringFromInputStream(is); return result; } else { } } catch (Exception e) { e.printStackTrace(); } finally { if(client != null){ // 断开连接，释放资源 client.getConnectionManager().shutdown(); } } return null; }

POST请求：

public String loginOfPost(String username, String password) { HttpClient client = null; try { // 定义客户端对象 client = new DefaultHttpClient(); // 声明Post方法 String uri = "http://xxx?"; HttpPost post = new HttpPost(uri); // 定义post的请求的参数 List<NameValuePair> parameters = new ArrayList<NameValuePair>(); parameters.add(new BasicNameValuePair("username", username)); parameters.add(new BasicNameValuePair("password", password)); // 包装post请求的参数 UrlEncodedFormEntity entity = new UrlEncodedFormEntity(parameters, "utf-8"); // 设置参数 post.setEntity(entity); // 使用客户端执行Post方法 HttpResponse response = client.execute(post); // 获得响应码，处理服务器返回的数据 int stateCode = response.getStatusLine().getStatusCode(); if (200 == stateCode) { InputStream is = response.getEntity().getContent(); // 解析服务器返回的数据 String result = getStringFromInputStream(is); return result; } else { } } catch (Exception e) { e.printStackTrace(); } finally { if(client != null){ // 断开连接，释放资源 client.getConnectionManager().shutdown(); } } return null; } /** * 根据流返回一个字符串信息 */ private String getStringFromInputStream(InputStream is) throws Exception { ByteArrayOutputStream baos = new ByteArrayOutputStream(); byte[] buffer = new byte[1024]; int len = -1; while ((len = is.read(buffer)) != -1) { baos.write(buffer, 0, len); } is.close(); String html = baos.toString(); // 把流中的数据转换成字符串, 采用的编码是: utf-8 // String html = new String(baos.toByteArray(), "GBK"); baos.close(); return html; }
