I have used the following code in the past and it had worked with basic authentication enabled in TomCat:

<pre><code>URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

myURLConnection.setRequestProperty ("Authorization", basicAuth);
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true);
</code></pre>

You can try the above code. The code above is for POST, and you can modify it for GET

blocks|key|464111|text|只是因为我在上面的答案中看不到这一点信息，最初发布的代码片段不能正常工作的原因是因为encodedBytes变量是byte[]而不是String值。如果您将byte[]传递给new+String()，如下所示，代码片段可以很好地工作。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|464112|encodedBytes+=+Base64.encode(authorization.getBytes(),+0);
authorization+=+"Basic+"+%2B+new+String(encodedBytes);|code-block|syntax|javascript|464113|entityMap^0|16|C|1L|6|1U|6|26|6|2F|C|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]|$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|X|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Y|8|@]|D|@]|E|$]]]|L|$]]

Just cause I don't see this bit of information in the answers above, the reason the code snippet originally posted doesn't work correctly is because the <code>encodedBytes</code> variable is a <code>byte[]</code> and not a <code>String</code> value. If you pass the <code>byte[]</code> to a <code>new String()</code> as below, the code snippet works perfectly.

<pre><code>encodedBytes = Base64.encode(authorization.getBytes(), 0);
authorization = "Basic " + new String(encodedBytes);
</code></pre>

Your code is fine.You can also use the same thing in this way.

<pre><code>public static String getResponseFromJsonURL(String url) {
 String jsonResponse = null;
 if (CommonUtility.isNotEmpty(url)) {
 try {
 /************** For getting response from HTTP URL start ***************/
 URL object = new URL(url);

 HttpURLConnection connection = (HttpURLConnection) object
 .openConnection();
 // int timeOut = connection.getReadTimeout();
 connection.setReadTimeout(60 * 1000);
 connection.setConnectTimeout(60 * 1000);
 String authorization="xyz:xyz$123";
 String encodedAuth="Basic "+Base64.encode(authorization.getBytes());
 connection.setRequestProperty("Authorization", encodedAuth);
 int responseCode = connection.getResponseCode();
 //String responseMsg = connection.getResponseMessage();

 if (responseCode == 200) {
 InputStream inputStr = connection.getInputStream();
 String encoding = connection.getContentEncoding() == null ? "UTF-8"
 : connection.getContentEncoding();
 jsonResponse = IOUtils.toString(inputStr, encoding);
 /************** For getting response from HTTP URL end ***************/

 }
 } catch (Exception e) {

 return jsonResponse;

Its Return response code 200 if authorizationis success

Step 1: Get HttpURLConnection object

<pre><code>URL url = new URL(urlToConnect);
HttpURLConnection httpUrlConnection = (HttpURLConnection) url.openConnection();
</code></pre>

Step 2: Add headers to the HttpURLConnection using setRequestProperty method.

<pre><code>Map&lt;String, String&gt; headers = new HashMap&lt;&gt;();

headers.put("X-CSRF-Token", "fetch");
headers.put("content-type", "application/json");

for (String headerKey : headers.keySet()) {
 httpUrlConnection.setRequestProperty(headerKey, headers.get(headerKey));
}
</code></pre>

I'm trying to add header for my request using <code>HttpUrlConnection</code> but the method <code>setRequestProperty()</code> doesn't seem working. The server side doesn't receive any request with my header.

<pre><code>HttpURLConnection hc;
 try {
 String authorization = "";
 URL address = new URL(url);
 hc = (HttpURLConnection) address.openConnection();


 hc.setDoOutput(true);
 hc.setDoInput(true);
 hc.setUseCaches(false);

 if (username != null &amp;&amp; password != null) {
 authorization = username + ":" + password;
 }

 if (authorization != null) {
 byte[] encodedBytes;
 encodedBytes = Base64.encode(authorization.getBytes(), 0);
 authorization = "Basic " + encodedBytes;
 hc.setRequestProperty("Authorization", authorization);
 }
</code></pre>
