Pass credentials while calling an API in Scala

Anil :

I'm trying to call a REST endpoint using HttpGet and pass user credentials.

var content = ""
val httpClient : CloseableHttpClient = HttpClients.createDefault();
val httpResponse = new HttpGet(url)
httpResponse.addHeader(BasicScheme.authenticate(new UsernamePasswordCredentials(“uname”,”pwd”),”UTF-8", false))
val response = httpClient.execute(httpResponse)
val entity = httpResponse.getEntity()
val inputStream = entity.getContent()
content = fromInputStream(inputStream).getLines.mkString
inputStream.close
httpClient.getConnectionManager().shutdown()
return content

Looks like BasicScheme is deprecated in "org.apache.http.impl.auth". Any pointers on how to move forward... Thanks in Advance.

Given you're trying to use basic authentication, this should be sufficient

val credentialsProvider = new BasicCredentialsProvider()
credentialsProvider.setCredentials(
    AuthScope.ANY, 
    new UsernamePasswordCredentials("username", "password")
)

val httpClient = 
    HttpClientBuilder.create()     
                     .setDefaultCredentialsProvider(credentialsProvider)
                     .build()

val httpResponse = new HttpGet(url)
httpClient.execute(httpResponse)

If instead you prefer going with a simple HTTP header, you can use

def buildEncodedCredentials(): String = {
    val credentialsString = username + ":" + password
    val charset = StandardCharsets.ISO_8859_1
    val encodedBytes = Base64.getEncoder().encode(credentialsString.getBytes(charset))
    return new String(encodedBytes, charset)
}

 httpResponse.addHeader(HttpHeaders.AUTHORIZATION, "Basic " + buildEncodedCredentials())
