在HttpClient中设置用于授权rest api的标头

HttpClient httpClient = HttpClient.newBuilder().build();

String url = "https://api.example.com/rest/api";
HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create(url))
        .method("GET", HttpRequest.BodyPublishers.noBody())
        .build();

String username = "your_username";
String password = "your_password";
String credentials = username + ":" + password;
String encodedCredentials = Base64.getEncoder().encodeToString(credentials.getBytes());

request = request.newBuilder()
        .header("Authorization", "Basic " + encodedCredentials)
        .build();
