android Post Get（普通）

0.HttpClient 

作用：执行Http请求的类，可以处理Cookie，身份验证，链接管理和其他。。

 

public HttpClient getHttpClient() {

        // 创建 HttpParams 以用来设置 HTTP 参数（这一部分不是必需的）
        this.httpParams = new BasicHttpParams();
        // 设置连接超时和 Socket 超时，以及 Socket 缓存大小
        HttpConnectionParams.setConnectionTimeout(httpParams, 20 * 1000);
        HttpConnectionParams.setSoTimeout(httpParams, 20 * 1000);
        HttpConnectionParams.setSocketBufferSize(httpParams, 8192);
        // 设置重定向，缺省为 true
        HttpClientParams.setRedirecting(httpParams, true);
        // 设置 user agent
        String userAgent = "Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.2) Gecko/20100115 Firefox/3.6";
        HttpProtocolParams.setUserAgent(httpParams, userAgent);
        // 创建一个 HttpClient 实例
        // 注意 HttpClient httpClient = new HttpClient(); 是Commons HttpClient
        // 中的用法，在 Android 1.5 中我们需要使用 Apache 的缺省实现 DefaultHttpClient
        httpClient = new DefaultHttpClient(httpParams);
        return httpClient;
    }

	StringBuffer path = new StringBuffer("www.baidu.com");
		path.append("?");
		path.append("name=zhangshan");
		try {
			path.append("password=" + URLEncoder.encode("1234", ""));
			HttpGet httpGet = new HttpGet(path.toString());
			HttpResponse reponse = new DefaultHttpClient().execute(httpGet);
			if (reponse.getStatusLine().getStatusCode() == 200) {
				String result = EntityUtils.toString(reponse.getEntity());
				String str = new String(result.getBytes("ISO_8859_1"), "utf-8");
				System.out.println(str);
				//return str;
			}
		} catch (UnsupportedEncodingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (ClientProtocolException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

２. Post

 

String url = " http://192.168.0.131:8888/kon_service/AddQuestionServlet";
			HttpClient client = new DefaultHttpClient();
			HttpParams httpParams = client.getParams();
			//设置网络超时参数
	        HttpConnectionParams.setConnectionTimeout(httpParams, 3000);
			HttpConnectionParams.setSoTimeout(httpParams, 5000);
			HttpPost request = new HttpPost(url);
			//设置HTTP POST请求参数必须用NameValuePair
			List<NameValuePair> params = new ArrayList<NameValuePair>();
			params.add(new BasicNameValuePair("title", ""));
			params.add(new BasicNameValuePair("content",""));
			params.add(new BasicNameValuePair("resolve",""));
			params.add(new BasicNameValuePair("u_id",""));
			try{
				//设置Http Post请求参数
				request.setEntity( new UrlEncodedFormEntity(params,HTTP.UTF_8));
				HttpResponse response = new DefaultHttpClient().execute(request);
				if(response.getStatusLine().getStatusCode()==200){
					String msg = EntityUtils.toString(response.getEntity());
					Toast.makeText(this, msg, Toast.LENGTH_LONG).show();
					Intent i = new Intent(this,TopActivity.class);
		       		startActivity(i);
