这篇CFSDN的博客文章基于HttpClient在HTTP协议接口测试中的使用(详解)由作者收集整理，如果你对这篇文章有兴趣，记得点赞哟.

HTTP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:

1、GET请求: GET请求时，参数一般是写在链接上的，代码如下:

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

如果想把参数不写在链接上，单独的传进去，则可以这样:

?

public void get(String url, Map< String , String> params){
   CloseableHttpClient httpClient = null;
   HttpGet httpGet = null;
   try {
     httpClient = HttpClients.createDefault();
     RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
     String ps = "";
     for (String pKey : params.keySet()) {
       if(!"".equals(ps)){
         ps = ps + "&";
       }
       ps = pKey+"="+params.get(pKey);
     }
     if(!"".equals(ps)){
       url = url + "?" + ps;
     }
     httpGet = new HttpGet(url);
     httpGet.setConfig(requestConfig);
     CloseableHttpResponse response = httpClient.execute(httpGet);
     HttpEntity httpEntity = response.getEntity();
     System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
   } catch (ClientProtocolException e) {
     e.printStackTrace();
   } catch (IOException e) {
     e.printStackTrace();
   }finally{
     try {
       if(httpGet!=null){
         httpGet.releaseConnection();
       }
       if(httpClient!=null){
         httpClient.close();
       }
     } catch (IOException e) {
       e.printStackTrace();
     }
   }
}

2、POST请求的表单提交方式，代码如下:

public void post(String url, Map< String , String> params){
   CloseableHttpClient httpClient = null;
   HttpPost httpPost = null;
   try {
     httpClient = HttpClients.createDefault();
     RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
     httpPost = new HttpPost(url);
     httpPost.setConfig(requestConfig);
     List< NameValuePair > ps = new ArrayList< NameValuePair >();
     for (String pKey : params.keySet()) {
       ps.add(new BasicNameValuePair(pKey, params.get(pKey)));
     }
     httpPost.setEntity(new UrlEncodedFormEntity(ps));
     CloseableHttpResponse response = httpClient.execute(httpPost);
     HttpEntity httpEntity = response.getEntity();
     System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
   } catch (ClientProtocolException e) {
     e.printStackTrace();
   } catch (IOException e) {
     e.printStackTrace();
   }finally{
     try {
       if(httpPost!=null){
         httpPost.releaseConnection();
       }
       if(httpClient!=null){
         httpClient.close();
       }
     } catch (IOException e) {
       e.printStackTrace();
     }
   }
}

3、 POST请求的RAW参数传递:

public void post(String url, String body){
   CloseableHttpClient httpClient = null;
   HttpPost httpPost = null;
   try {
     httpClient = HttpClients.createDefault();
     RequestConfig requestConfig = RequestConfig.custom().setSocketTimeout(20000).setConnectTimeout(20000).build();
     httpPost = new HttpPost(url);
     httpPost.setConfig(requestConfig);
     httpPost.setEntity(new StringEntity(body));
     CloseableHttpResponse response = httpClient.execute(httpPost);
     HttpEntity httpEntity = response.getEntity();
     System.out.println(EntityUtils.toString(httpEntity,"utf-8"));
   } catch (ClientProtocolException e) {
     e.printStackTrace();
   } catch (IOException e) {
     e.printStackTrace();
   }finally{
     try {
       if(httpPost!=null){
         httpPost.releaseConnection();
       }
       if(httpClient!=null){
         httpClient.close();
       }
     } catch (IOException e) {
       e.printStackTrace();
     }
   }
}
