Java學習心得之 HttpClient的GET和POST請求

1. 前言
2. GET請求
3. POST請求 

 

一、前言

本篇博文記錄了HttpClient的GET和POST請求

本文內容基於以下文章：

http://huangqiqing123.iteye.com/blog/2054436 　　　　　　　　　　　　　　        (HttpClient之 addHeader與setHeader)
http://zywang.iteye.com/blog/916834 　　　　　　　　　　　　　　　　　　        　(使用Apache HttpClient訪問JSP發送GET和POST請求)
http://www.linuxidc.com/Linux/2012-02/55502p3.htm 　　　　　　　　　　　　     (HttpClient 4.0的使用詳解)

 

二、GET請求

GET請求的執行個體如下：

    //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請求：

GET請求的執行個體如下：

    //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;
