java 发送带Basic Auth认证的http post请求实例代码

构造http header

private static final String URL = "url";
private static final String APP_KEY = "key";
private static final String SECRET_KEY = "secret";

    /**
   * 构造Basic Auth认证头信息
   * 
   * @return
   */
  private String getHeader() {
    String auth = APP_KEY + ":" + SECRET_KEY;
    byte[] encodedAuth = Base64.encodeBase64(auth.getBytes(Charset.forName("US-ASCII")));
    String authHeader = "Basic " + new String(encodedAuth);
    return authHeader;
  }

方式一：

private void send(JPushObject pushObject) {
    CloseableHttpClient client = HttpClients.createDefault();
    HttpPost post = new HttpPost(URL);
    System.out.println("要发送的数据" + JSON.toJSONString(pushObject));
    StringEntity myEntity = new StringEntity(JSON.toJSONString(pushObject), ContentType.APPLICATION_JSON); // 构造请求数据
    post.addHeader("Authorization", getHeader());
    post.setEntity(myEntity); // 设置请求体
    String responseContent = null; // 响应内容
    CloseableHttpResponse response = null;
    try {
        response = client.execute(post);
        System.out.println(JSON.toJSONString(response));
        if (response.getStatusLine().getStatusCode() == 200) {
            HttpEntity entity = response.getEntity();
            responseContent = EntityUtils.toString(entity, "UTF-8");
        }
        
        if (response != null) 
            response.close();
        if (client != null) 
            client.close();
        
        System.out.println("responseContent:" + responseContent);
        
    } catch(ClientProtocolException e) {
        e.printStackTrace();
    } catch(IOException e) {
        e.printStackTrace();
    } 
}
