Adding a proxy settings to Microsoft Graph Client in Java

Question

I am trying to implement GraphClient, below is a sample code which is working fine...

   ClientCredentialProvider authProvider = 
              new ClientCredentialProvider(clientId,
                      scopes,
                      clientSecret,
                      b2cTenant,
                      endpoint);
    
    IGraphServiceClient graphClient = graphClient = GraphServiceClient.builder()
                .authenticationProvider(authProvider)
                .buildClient();

This is working fine...but in some case from where the code is being run, there is a proxy, so I need to setup proxy to connect to internet. I need to setup proxy and pass it to graphClient somehow to tell make a call via proxy.

I was trying to find a document but could not get any through I got this...

ProxyOptions proxyOptions = new ProxyOptions(ProxyOptions.Type.HTTP, new InetSocketAddress(proxyUrl, proxyPort));
proxyOptions.setCredentials(proxyUser, proxyPassword);

final UsernamePasswordCredential usernamePasswordCredential = new UsernamePasswordCredentialBuilder()
                    .clientId(clientId)
                    .username(username)
                    .password(password)
                    .httpClient(HttpClient.createDefault(new HttpClientOptions().setProxyOptions(proxyOptions)))
                    .build();

But the problem is the "ProxyOptions" isnt in Maven and I am not sure what library it is part of.

Can anyone suggest an idea.

        ProxyOptions proxyOptions = new ProxyOptions(
               ProxyOptions.Type.HTTP, new InetSocketAddress(hostAddress, hostPort));
        
        HttpClientOptions clientOptions = new HttpClientOptions();
        clientOptions.setProxyOptions(proxyOptions); 
        
        HttpClient azHttpClient = HttpClient.createDefault(clientOptions);
        
        ClientSecretCredential clientSecretCredential = new ClientSecretCredentialBuilder()
                .clientId(clientId)
                .clientSecret(clientSecret)
                .tenantId(tenantId)
                .httpClient(azHttpClient)
                .build();

        TokenCredentialAuthProvider tokenCredentialAuthProvider = 
            new TokenCredentialAuthProvider(scopes, clientSecretCredential);
        
        Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress(hostAddress, hostPort));
        
        OkHttpClient httpClient = HttpClients.createDefault(tokenCredentialAuthProvider)
                .newBuilder()
                .proxy(proxy)
                .build();

        graphClient = GraphServiceClient.builder()
                .authenticationProvider(tokenCredentialAuthProvider)
                .httpClient(httpClient)
                .buildClient();

in terms of Maven, <dependency> <groupId>com.azure</groupId> <artifactId>azure-core-http-netty</artifactId> <version>1.9.2</version> </dependency>

Please - where is the DefaultClientConfig defined? cannot find it in any dependency :(

Sharad esdee Dutta Over a year ago

@Frk I am updating the answer, MS has updated the library.

Sharad esdee Dutta Over a year ago

@Frk Proxy class belongs to java.net.Proxy and OkHttpClient belongs to okhttp3 library, everything else is from com.azure.

If you can use system properties then try to configure via

https.proxyHost and https.proxyPort

Never change system properties like this. NOT recommended.
