Making a Http Get Request with Http-Basic Authentication

Making a HTTP GET request with HTTP-Basic authentication

Using file_get_contents() with a stream to specify the HTTP credentials, or use curl and the CURLOPT_USERPWD option.

Angular 6 HTTP Get request with HTTP-Basic authentication

Refer to https://angular.io/guide/http or https://v6.angular.io/guide/http#adding-headers

import { HttpHeaders } from '@angular/common/http';

const httpOptions = {
  headers: new HttpHeaders({
    'Content-Type':  'application/json',
    'Authorization': 'Basic ' + btoa('username:password')
  })
};

Then use the headers:

return this.http.get<AObjects[]>(this.postsURL, httpOptions); 

Make a http request with basic authentication

I use the following in my code to create a default session that include the authentication:

static func defaultURLSession(username : String, password:String) -> NSURLSession {
    let config = NSURLSessionConfiguration.defaultSessionConfiguration()
    let userPasswordString = "\(username):\(password)"
    let userPasswordData = userPasswordString.dataUsingEncoding(NSUTF8StringEncoding)
    let base64EncodedCredential = userPasswordData!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.EncodingEndLineWithCarriageReturn)
    let authString = "Basic \(base64EncodedCredential)"
    config.HTTPAdditionalHeaders = ["Authorization" : authString]

    return NSURLSession(configuration: config)
}

HTTP requests with basic authentication

You can use an Authenticator. For example:

Authenticator.setDefault(new Authenticator() {
 @Override
        protected PasswordAuthentication getPasswordAuthentication() {
         return new PasswordAuthentication(
   "user", "password".toCharArray());
        }
});

This sets the default Authenticator and will be used in all requests. Obviously the setup is more involved when you don't need credentials for all requests or a number of different credentials, maybe on different threads.

Alternatively you can use a DefaultHttpClient where a GET request with basic HTTP authentication would look similar to:

HttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://foo.com/bar");
httpGet.addHeader(BasicScheme.authenticate(
 new UsernamePasswordCredentials("user", "password"),
 "UTF-8", false));

HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity responseEntity = httpResponse.getEntity();

// read the stream returned by responseEntity.getContent()

I recommend using the latter because it gives you a lot more control (e.g. method, headers, timeouts, etc.) over your request.

Http request with basic auth java

Check this. It worked for me.

  try {
        String webPage = "http://192.168.1.1";
        String name = "admin";
        String password = "admin";

        String authString = name + ":" + password;
        System.out.println("auth string: " + authString);
        byte[] authEncBytes = Base64.encodeBase64(authString.getBytes());
        String authStringEnc = new String(authEncBytes);
        System.out.println("Base64 encoded auth string: " + authStringEnc);

        URL url = new URL(webPage);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);
        InputStream is = urlConnection.getInputStream();
        InputStreamReader isr = new InputStreamReader(is);

        int numCharsRead;
        char[] charArray = new char[1024];
        StringBuffer sb = new StringBuffer();
        while ((numCharsRead = isr.read(charArray)) > 0) {
            sb.append(charArray, 0, numCharsRead);
        }
        String result = sb.toString();

        System.out.println("*** BEGIN ***");
        System.out.println(result);
        System.out.println("*** END ***");
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

How do I use HTTP Basic Auth with http-client?

(define user "user")
(define pass "pass")

(determine-username/password
 (lambda (uri realm)
   (values user pass)))

See https://wiki.call-cc.org/eggref/5/http-client#authentication-support for the technical details.
