Java訪問用戶名密碼驗證的url

引言

有些url帶有用戶名密碼，我們直接用curl或者wget訪問的時候出現401，沒有訪問權限。這時我們就需要對url進行必要的權限處理

代碼解釋

private static String Post1(String url, String hexString) throws IOException {CloseableHttpClient client = HttpClients.createDefault();HttpPost get = new HttpPost(url);StringEntity stringEntity = new StringEntity("json="+hexString);stringEntity.setContentType("application/x-www-form-urlencoded");get.setEntity(stringEntity);ProtocolVersion protocolVersion = get.getProtocolVersion();System.out.println(protocolVersion.getProtocol());try {//該網頁需要認證（用戶名、密碼）HttpClientContext context = new HttpClientContext();CredentialsProvider credentialsProvider = new BasicCredentialsProvider();credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials("admin", "admin"));context.setCredentialsProvider(credentialsProvider);CloseableHttpResponse execute = client.execute(get, context);//----以下一樣HttpEntity entity = execute.getEntity();InputStream in = entity.getContent();StringBuilder builder = new StringBuilder();BufferedReader bufreader = new BufferedReader(new InputStreamReader(in));for (String temp = bufreader.readLine(); temp != null; temp = bufreader.readLine()) {builder.append(temp);}return builder.toString();} catch (ClientProtocolException e) {throw new RuntimeException(e);} catch (IOException e) {throw new RuntimeException(e);} }
