TTP协议的接口测试中，使用到最多的就是GET请求与POST请求，其中POST请求有FORM参数提交请求与RAW请求，下面我将结合HttpClient来实现一下这三种形式：

一.GET请求: GET请求时，参数一般是写在链接上的，代码如下：

 1 public void get(String url){
 2     CloseableHttpClient httpClient = null;
 3     HttpGet httpGet = null;
 4     try {
 5         httpClient = HttpClients.createDefault();
 6         RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();     
 7         httpGet = new HttpGet(url);
 8         httpGet.setConfig(requestConfig);
 9         CloseableHttpResponse response = httpClient.execute(httpGet);
10         HttpEntity httpEntity = response.getEntity();
11         System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
12     } catch (ClientProtocolException e) {
13         e.printStackTrace();
14     } catch (IOException e) {
15         e.printStackTrace();
16     }finally{
17         try {
18             if(httpGet!=null){
19                 httpGet.releaseConnection();
20             }
21             if(httpClient!=null){
22                 httpClient.close();
23             }
24         } catch (IOException e) {
25             e.printStackTrace();
26         }
27     }
28 }

二. POST请求的表单提交方式,代码如下:

 1 public void post(String url, Map<String, String> params){
 2     CloseableHttpClient httpClient = null;
 3     HttpPost httpPost = null;
 4     try {
 5         httpClient = HttpClients.createDefault();
 6         RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
 7         httpPost = new HttpPost(url);
 8         httpPost.setConfig(requestConfig);
 9         List<NameValuePair> ps = new ArrayList<NameValuePair>();
10         for (String pKey : params.keySet()) {
11             ps.add(new BasicNameValuePair(pKey, params.get(pKey)));
12         }
13         httpPost.setEntity(new UrlEncodedFormEntity(ps));
14         CloseableHttpResponse response = httpClient.execute(httpPost);
15         HttpEntity httpEntity = response.getEntity();
16         System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
17     } catch (ClientProtocolException e) {
18         e.printStackTrace();
19     } catch (IOException e) {
20         e.printStackTrace();
21     }finally{
22         try {
23             if(httpPost!=null){
24                 httpPost.releaseConnection();
25             }
26             if(httpClient!=null){
27                 httpClient.close();
28             }
29         } catch (IOException e) {
30             e.printStackTrace();
31         }
32     }
33 }

三. POST请求的RAW参数传递:

 1 public void post(String url, String body){
 2     CloseableHttpClient httpClient = null;
 3     HttpPost httpPost = null;
 4     try {
 5         httpClient = HttpClients.createDefault();
 6         RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
 7         httpPost = new HttpPost(url);
 8         httpPost.setConfig(requestConfig);
 9         httpPost.setEntity(new StringEntity(body));
10         CloseableHttpResponse response = httpClient.execute(httpPost);
11         HttpEntity httpEntity = response.getEntity();
12         System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
13     } catch (ClientProtocolException e) {
14         e.printStackTrace();
15     } catch (IOException e) {
16         e.printStackTrace();
17     }finally{
18         try {
19             if(httpPost!=null){
20                 httpPost.releaseConnection();
21             }
22             if(httpClient!=null){
23                 httpClient.close();
24             }
25         } catch (IOException e) {
26             e.printStackTrace();
27         }
28     }
29 }
