HTTP協議的接口測試中,使用到最多的就是GET請求與POST請求,其中POST請求有FORM參數提交請求與RAW請求,下面我將結合HttpClient來實現一下這三種形式:java
一.GET請求: GET請求時,參數通常是寫在連接上的,代碼以下:post
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(); } } }
若是想把參數不寫在連接上,單獨的傳進去,則能夠這樣:測試
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請求的表單提交方式,代碼以下:ui
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請求的RAW參數傳遞:url
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(); } } }
