Azure 存储 - Java 代码中的代理设置

Question

In a java service, I'm trying to upload a file in an azure storage directory; therefore I've written a code like this:

import com.azure.core.util.*;
import com.azure.storage.file.share.*;
import com.azure.storage.file.share.models.*;

 //Create connexion string
String connectStr ="DefaultEndpointsProtocol=https;AccountName=" + accountName + ";AccountKey=" + accountKey + ";EndpointSuffix=" + endpoint;
            
//ShareDirectoryClient
            
ShareDirectoryClient dirClient = new     ShareFileClientBuilder().connectionString(connectStr).shareName(shareName).resourcePath(directoryName).configuration(proxyOptions).buildDirectoryClient();
            
// Create empty file
dirClient.createFile(fileName, body.length());

The HTTPS request must goes through a proxy server, so, I get this error:

"Could not run 'sendFileInDirectoryProxyTest' reactor.core.Exceptions$ReactiveException: io.netty.channel.AbstractChannel$AnnotatedConnectException: Connection timed out: no further information: "

I can't set/use a global setting. To set a proxy in the Java code, I've tried several things, like using the Configuration Class:

Configuration configuration = new Configuration();
configuration.put("java.net.useSystemProxies", "true");
configuration.put("https.proxyHost", "xxxxxxxxx");
configuration.put("https.proxyPort", "xxxx");
            
ShareDirectoryClient dirClient = new     ShareFileClientBuilder().connectionString(connectStr).shareName(shareName).resourcePath(directoryName).configuration(configuration).buildDirectoryClient();
            

But it did not solve the issue. I'm sure it is pretty simple, any help would be appreciated. Thanks. Charles de Saint Andre.

You need to configure ProxyOptions and set them on the httpClientBuilder. All our Storage client builders have a.httpClient() method that accepts a client, and you can build a client with all defaults + the proxy options using a NettyAsyncClientBuilder(), which has a.proxyOptions() method. Please give that a try and let me know if you have any more issues. Sample: azure-sdk-for-java/sdk/storage/azure-storage-blob at main · Azure/azure-sdk-for-java (github.com)
