httpclient问题求大神，executeMethod如何么到response? httpClient.executeMethod(get);

Posted 2023-03-10

private static HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(httppost);

private static HttpClient httpClient = new HttpClient(httpConnectManager);
int status = httpClient.executeMethod(get);

executeMethod方法如何得到返回的response结果。

/**
 * 专门处理返回值是json串的httppost请求
 * 
 * @param map 请求参数的键值对
 * @param url 请求地址
 * @param clazz 返回类型
 * @return
 */
public <T> T doHttpPost(Map<String, String> map, String url, Class<T> clazz) 
// System.out.println(map);
CloseableHttpClient hp = HttpClients.createDefault();
HttpPost post = new HttpPost(url);
List<NameValuePair> param = new ArrayList<NameValuePair>();
for (Entry<String, String> en : map.entrySet())
param.add(new BasicNameValuePair(en.getKey(), en.getValue()));
post.setEntity(new UrlEncodedFormEntity(param, Charset.forName("utf-8")));
String result = "";
try 
CloseableHttpResponse response = hp.execute(post);
result = EntityUtils.toString(response.getEntity());
// System.out.println(result);
T re = gson.fromJson(result, clazz);
return re;
 catch (Exception e) 
System.err.println(result);
e.printStackTrace();
 finally 
try 
hp.close();
 catch (IOException e) 
// TODO Auto-generated catch block
e.printStackTrace();


return null;

自己封装的一个方法，通过Apache httpclient 官网教程封装的一个处理rest请求的方法

（ps：这里需要Gson对json串转换）

参考技术A String getTokenUrl = "";

HttpClient client = new HttpClient();
GetMethod get = new GetMethod(getTokenUrl);
client.executeMethod(get);
if (get.getStatusCode() != HttpStatus.SC_OK)
System.out.println("获取失败，无返回");

String repMsg = get.getResponseBodyAsString();
System.out.println("获取repMsg = " + repMsg); 参考技术B 通过get.getResponseBody()获取响应内容
