本篇博文记录了HttpClient的GET和POST请求
本文内容基于以下文章：
http://huangqiqing123.iteye.com/blog/2054436 (HttpClient之 addHeader与setHeader)
http://zywang.iteye.com/blog/916834 (使用Apache HttpClient访问JSP发送GET和POST请求)
http://www.linuxidc.com/Linux/2012-02/55502p3.htm (HttpClient 4.0的使用详解)
GET请求的实例如下：
//httpClient HttpClient httpClient = new DefaultHttpClient(); // get method HttpGet httpGet = new HttpGet("https://api.microsofthealth.net/v1/me/Summaries/Daily"); // set header String Au="Bearer "+access_token; httpGet.setHeader("Authorization",Au); //response HttpResponse response = null; try{ response = httpClient.execute(httpGet); }catch (Exception e) {} //get response into String String temp=""; try{ HttpEntity entity = response.getEntity(); temp=EntityUtils.toString(entity,"UTF-8"); }catch (Exception e) {} return temp;
GET请求的实例如下：
//httpClient HttpClient httpClient = new DefaultHttpClient(); // get method HttpPost httpPost = new HttpPost("https://login.live.com/oauth20_token.srf"); // set header httpPost.setHeader("Content-Type","application/x-www-form-urlencoded"); //set params List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("client_id",client_id)); params.add(new BasicNameValuePair("redirect_uri",redirect_uri)); params.add(new BasicNameValuePair("client_secret",client_secret)); params.add(new BasicNameValuePair("code",code)); params.add(new BasicNameValuePair("grant_type","authorization_code")); try{ httpPost.setEntity(new UrlEncodedFormEntity(params)); }catch (Exception e) {} //response HttpResponse response = null; try{ response = httpClient.execute(httpPost); }catch (Exception e) {} //get response into String String temp=""; try{ HttpEntity entity = response.getEntity(); temp=EntityUtils.toString(entity,"UTF-8"); }catch (Exception e) {} return temp;
