java发送带BasicAuth认证的httppost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 = Bytes(Charset.forName("US-ASCII")));
String authHeader = "Basic " + new String(encodedAuth);
return authHeader;
}
⽅式⼀：
private void send(JPushObject pushObject) {
CloseableHttpClient client = ateDefault();
HttpPost post = new HttpPost(URL);
System.out.println("要发送的数据" + JSONString(pushObject));
StringEntity myEntity = new JSONString(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 = ute(post);
System.out.JSONString(response));
if (StatusLine().getStatusCode() == 200) {
HttpEntity entity = Entity();
responseContent = String(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();
}
}
