http post 方法傳遞參數的2種方式

 try{ HttpPost httpPost = new HttpPost(url); StringEntity stringEntity = new StringEntity(param);//param參數，可以為"key1=value1&key2=value2"的一串字符串
        stringEntity.setContentType("application/x-www-form-urlencoded"); httpPost.setEntity(stringEntity); HttpClient client = new DefaultHttpClient(); HttpResponse httpResponse = client.execute(httpPost); String result = EntityUtils.toString(httpResponse.getEntity(), HTTP.UTF_8); } catch(IOException e){ }

有的時候我們不想要通過下面的方式來傳遞參數，因為考慮請求接口時我比較喜歡的方式是直接把key和value連成一串，如"key1=value1&key2=value2"來作為參數，這樣http get和post的方法都可以用同樣的結構來作為參數，於是http post的方法請求服務器數據時可以用上面的方法來實現.

List<NameValuePair>list = new ArrayList<NameValuePair>(); for (int i = 0; i < keys.length; i++) { list.add(new BasicNameValuePair(keys[i], values[i])); } HttpPost httpRequst = new HttpPost(urlString); httpRequst.setEntity(new UrlEncodedFormEntity(list,HTTP.UTF_8));

httpRequst.setEntity()這個方法是最主要的post傳遞的參數實現的方式了（不知道這樣說對不對）

 httpEntity有AbstractHttpEntity, BasticHttpEntity, BasicManageEntity, BufferedHttpEntity, ByteArrayEntity, EntityTemplate,  FileEntity, HttpEntityWrapper, InputStreamEntity, SerializableEntity, StringEntity, UrlEncodedFormEntity
