I am having difficulty connecting to Microsoft graph api through a Basic authenticated proxy (an unauthenticated proxy works fine meaning I can always create a new client). I have double checked that the proxy is up and running and that the proxy credentials are correct. Below is how I have set up the ClientSecretCredential and the GraphServiceClient, both use the proxy host, port, username and password. I have also included the stack trace as well (sorry for the length). I will note that almost the identical ClientSecretCredential and GraphServiceClient code worked for the previous Microsoft/Azure libraries (I can provide exact libraries). Is there something that I am missing? I've checked multiple posts and everything looks like it should be working fine.
Thank you, any help would be greatly appreciated!
EDIT: I am looking to create a new Graph client with up-to-date proxy configuration. It seems like I can create new Clients no problem with unauthenticated proxies, but not authenticated proxies. See this post. Is there a way to create a new Client with each request for authenticated proxies?
private ClientSecretCredential getClientSecretCredential()
{
ClientSecretCredentialBuilder clientSecretCredentialBuilder = new ClientSecretCredentialBuilder()
.clientId(clientid)
.clientSecret(clientsecret)
.tenantId(tenantid);
ProxyOptions proxyOptions = new ProxyOptions(ProxyOptions.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort));
proxyOptions.setCredentials(proxyUsername, proxyPassword);
return clientSecretCredentialBuilder
.httpClient(HttpClient.createDefault(new HttpClientOptions().setProxyOptions(proxyOptions)))
.build();
}
private GraphServiceClient createClientDetails()
{
SwitchableAuthProvider authProvider = new SwitchableAuthProvider();
OkHttpClient.Builder httpClientBuilder = HttpClients.createDefault(authProvider)
.newBuilder();
httpClientBuilder.proxy(new Proxy(Proxy.Type.HTTP, new InetSocketAddress(proxyHost, proxyPort)));
Authenticator proxyAuthenticator = (route, response) ->
{
String credential = Credentials.basic(proxyUsername, proxyPassord);
return response.request().newBuilder()
.header("Proxy-Authorization", credential)
.build();
};
OkHttpClient proxyClient = httpClientBuilder.proxyAuthenticator(proxyAuthenticator).build();
return GraphServiceClient.builder()
.authenticationProvider(authProvider)
.httpClient(proxyClient)
.buildClient();
}
