【问题描述】：

我正在尝试将 base64 图像上传到 Azure 存储文件共享，但发生错误。

我该如何解决？

ShareFileClient dirClient = new ShareFileClientBuilder()
    .endpoint("https://xxx.file.core.windows.net")
    .shareName("xxx")
    .resourcePath("photos")
    .credential(new StorageSharedKeyCredential("xxx", "xxx"))
    .buildFileClient();

    byte[] bytes = Base64.decodeBase64("iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==");

    try (ByteArrayInputStream dataStream = new ByteArrayInputStream(bytes)) 
        dirClient.upload(dataStream, bytes.length);
     catch (IOException e) 
        e.printStackTrace();
    

pom.xml

<dependency>
    <groupId>com.azure</groupId>
    <artifactId>azure-storage-file-share</artifactId>
    <version>12.2.0</version>
</dependency>

解决方案

// Create a source file client
ShareFileClient dirClient = new ShareFileClientBuilder()
    .endpoint("https://xxx.file.core.windows.net")
    .shareName("xxx")
    .credential(new StorageSharedKeyCredential("xxx", "xxx"))
    .resourcePath("photos" + "/" + "test.png")
    .buildFileClient();

var base64Image = "iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==";

// Create a source file
try 
    var sizeInBytes = 4 * Math.ceil(base64Image.length() / 3)*0.5624896334383812;
    dirClient.create((long) sizeInBytes);
 catch (ShareStorageException e) 
    System.out.println("Failed to create source client. Reasons: " + e.getMessage());


// decodeBase64
byte[] bytes = Base64.decodeBase64(base64Image);

// Upload
try (ByteArrayInputStream dataStream = new ByteArrayInputStream(bytes)) 
    dirClient.upload(dataStream, bytes.length);
 catch (IOException e) 
    e.printStackTrace();
