使用HttpClient进行HTTP BASIC验证

1.maven项目引入HttpClient依赖，或导入jar包

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.5.1</version>
</dependency>

2.编写方法，输入定义的用户名、密码，返回一个httpClient对象

public static CloseableHttpClient getHttpClient(){CredentialsProvider provider = new BasicCredentialsProvider();UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(USERNAME, PASSWORD);provider.setCredentials(AuthScope.ANY, credentials);return  HttpClients.custom().setDefaultCredentialsProvider(provider).build();
}

3.将返回的httpClient对象使用HttpClient发出get或post等请求

public static String createStream(String url, String name) {CloseableHttpClient httpClient = getHttpClient();HttpPost httpPost = new HttpPost(url);String s = "";List<NameValuePair> parameters = new ArrayList<NameValuePair>();parameters.add(new BasicNameValuePair("name", name));try {UrlEncodedFormEntity formEntity = new UrlEncodedFormEntity(parameters,"UTF-8");httpPost.setEntity(formEntity);CloseableHttpResponse response = httpClient.execute(httpPost);HttpEntity entity = response.getEntity();s = EntityUtils.toString(entity);System.out.println(s);httpClient.close();} catch (ClientProtocolException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}return s;
}
