基于HttpClient在HTTP协议接口测试中的使用(详解)

2021-01-15 13:48张飞_ Java教程

下面小编就为大家带来一篇基于HttpClient在HTTP协议接口测试中的使用(详解)。小编觉得挺不错的，现在就分享给大家，也给大家做个参考。一起跟随小编过来看看吧

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：

一、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();
    }
  }
}

二、POST请求的表单提交方式，代码如下：

12

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();
    }
  }
}

三、 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();
    }
  }
}
