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();
}
}
