androidhttpclient用android的httpclient抓网页（GET）有的可以，有的网页抓不到，请求头设置了。

安卓怎么使用httpclient

构造完整的URL 设置一段间隔时间参数，保证HTTP连接顺利建立成功 构造HttpClient的实例，并传入Httpparams参数 创建GET方法的实例，并传入URL地址 使用httpclient执行httpGet进行联网，返回httpResponse(带有数据) 获得返回结果，并将数据变成String类型，方便使用JSON进行解析

android httpclient 怎样实现将安卓的一段数据（字符串）上传到服务器 服务器php+apache 怎么接收

手机端的------// 提交反馈信息，这是post方式提交 服务端，php不懂说以，你再找找，跟客户端关系不大 public String user_feedback(String feedbackType,String feedbackContent,String contacts) { ArrayList<NameValuePair> nv=new ArrayList<NameValuePair>(); nv.add(new BasicNameValuePair("userId", this.user.userid)); nv.add(new BasicNameValuePair("feedbackType", feedbackType)); nv.add(new BasicNameValuePair("feedbackContent",feedbackContent)); nv.add(new BasicNameValuePair("userContact",contacts)); nv.add(new BasicNameValuePair("permit", this.user.permit)); DefaultHttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost(uri); String strResult = ""; try { HttpEntity entity = new UrlEncodedFormEntity(nv, "UTF-8"); post.setEntity(entity); // 获得HttpResponse对象 HttpResponse httpResponse = client.execute(post); if (httpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) { // 取得返回的数据 strResult = EntityUtils.toString(httpResponse.getEntity()); } } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } Log.i("jsonHelper", strResult); return strResult; }

用android的httpclient抓网页（GET）有的可以，有的网页抓不到，请求头设置了。

可使用android自带的httpclient框架实现。

1. GET 方式传递参数 //先将参数放入List，再对参数进行URL编码 List params = new LinkedList(); params.add(new BasicNameValuePair("param1", "数据")); //增加参数1 params.add(new BasicNameValuePair("param2", "value2"));//增加参数2 String param = URLEncodedUtils.format(params, "UTF-8");//对参数编码 String baseUrl = "服务器接口完整URL"; HttpGet getMethod = new HttpGet(baseUrl + "?" + param);//将URL与参数拼接 HttpClient httpClient = new DefaultHttpClient(); try { HttpResponse response = httpClient.execute(getMethod); //发起GET请求 Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码 Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8"));//获取服务器响应内容 } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } 2. POST方式 方式传递参数 //和GET方式一样，先将参数放入List params = new LinkedList(); params.add(new BasicNameValuePair("param1", "Post方法"));//增加参数1 params.add(new BasicNameValuePair("param2", "第二个参数"));//增加参数2 try { HttpPost postMethod = new HttpPost(baseUrl);//创建一个post请求 postMethod.setEntity(new UrlEncodedFormEntity(params, "utf-8")); //将参数填入POST Entity中 HttpResponse response = httpClient.execute(postMethod); //执行POST方法 Log.i(TAG, "resCode = " + response.getStatusLine().getStatusCode()); //获取响应码 Log.i(TAG, "result = " + EntityUtils.toString(response.getEntity(), "utf-8")); //获取响应内容 } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
