Java学习心得之 HttpClient的GET和POST请求
1. 前言
2. GET请求
3. POST请求
一、前言
本篇博文记录了HttpClient的GET和POST请求
本文内容基于以下文章:

二、GET请求
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;
三、POST请求:
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;
