检查Azure中是否存在Blob [英] Check if blob exists in Azure

问题描述

我想知道是否有一种方法可以检查容器中是否存在斑点?

    $blob = $blobRestProxy->getBlob("mycontainer", "myblobname");
    if($blob){
        return 'exists';
    } else {
        return 'not exists';
    }

我已经尝试过，但是只要不存在blob，我都会收到此消息:

BlobNotFound 指定的Blob不存在.

如果存在，则代码自然返回存在".我对列出容器中的所有blob并进行迭代直到找到匹配原因不感兴趣，因为我有很多blob.

解决方案

当blob不存在时，函数getBlob将引发ServiceException异常并退出PHP进度，以下代码将不起作用./p>

请尝试在代码中添加try catch语句，例如.

try {
    $blob = $tableRestProxy->getBlob("mycontainer", "myblobname");
    return 'exists';
} catch (ServiceException $e) {
    return 'not exists';
} 

I'm wondering if there is a way to check if a blob exists in a container?

    $blob = $blobRestProxy->getBlob("mycontainer", "myblobname");
    if($blob){
        return 'exists';
    } else {
        return 'not exists';
    }

I've tried this but im getting this message whenever the blob does not exists:

BlobNotFoundThe specified blob does not exist.

If exists, the code returns 'exists' naturally. I'm not interested in listing all blobs in the container and iterating until I find a match cause I have a lot of blobs.

解决方案

When the blob does not exist, the function getBlob will raise a ServiceException exception and exit the PHP progress, the following code will not work.

Please try to add the try catch statement in your code, E.G.

try {
    $blob = $tableRestProxy->getBlob("mycontainer", "myblobname");
    return 'exists';
} catch (ServiceException $e) {
    return 'not exists';
}
