java - 适用于 blob 的 Azure Java SDK - 发出了加载默认 HttpClient 提供程序的请求，但在类路径中找不到该提供程序

Question

已关注 https://learn.microsoft.com/en-us/azure/storage/blobs/storage-quickstart-blobs-java?tabs=powershell收到此错误:

Caused by: java.lang.IllegalStateException: A request was made to load the default HttpClient provider but one could not be found on the classpath. If you are using a dependency manager, consider including a dependency on azure-core-http-netty or azure-core-http-okhttp. Depending on your existing dependencies, you have the choice of Netty or OkHttp implementations. Additionally, refer to https://aka.ms/azsdk/java/docs/custom-httpclient to learn about writing your own implementation.

error找不到 HttpClient 时会发生。貌似和代码无关。尝试检查您是否按照文档中的步骤操作。

我在 App.java 中尝试了以下代码，效果很好。

StorageSharedKeyCredential credential = new StorageSharedKeyCredential(accountName, accountKey);
BlobServiceClient blobServiceClient = new BlobServiceClientBuilder().endpoint(endpoint).credential(credential).buildClient();

如果删除credential()，则会返回此错误:ResourceNotFound 指定的资源不存在。

无需凭据即可访问公共(public) blob:
