Configure Http Client

MSAL lets you provide your own Http client for supporting fine grained configurations.

Do use a custom Http client, you'll first need to implement IHttpClient. This class, which we will class HttpClientAdapter for the remainder of this document, should implement a method send. send should take in the HttpRequest composed by MSAL, execute it, and then construct IHttpResponse with the results of the execution.

Once HttpClientAdapter has been implemented, it can be set on the client application for which you would like to use it.

class OkHttpClientAdapter implements IHttpClient{

    private OkHttpClient client;

    OkHttpClientAdapter(){

        // You can configure OkHttpClient 
        this.client = new OkHttpClient();  
    }

    @Override
    public IHttpResponse send(HttpRequest httpRequest) throws IOException {
        
        // Map URL, headers, and body from MSAL's HttpRequest to OkHttpClient request object  
        Request request = buildOkRequestFromMsalRequest(httpRequest);

        // Execute Http request with OkHttpClient
        Response okHttpResponse= client.newCall(request).execute();
     
        // Map status code, headers, and response body from OkHttpClient's Response object to MSAL's IHttpResponse
        return buildMsalResponseFromOkResponse(okHttpResponse);
    }

        PublicClientApplication pca = PublicClientApplication.builder(
                labResponse.getAppId()).
                authority(AUTHORITY).
                httpClient( new OkHttpClientAdapter()).
                build();
