我有以下Azure Cli命令,该命令列出了给定存储帐户和容器中的文件:
az storage blob list --container-name $web --account-name mystorageaccount
在运行时,它会以JSON格式正确返回所有结果。
我希望将返回的结果限制为当前使用冷层存储的那些项。
例如将properties.BlobTier设置为Cold的地方。
例如返回的响应之一如下所示:
{
"content": null,
"deleted": false,
"metadata": null,
"name": "index.html",
"properties": {
"appendBlobCommittedBlockCount": null,
"blobTier": "Cold",
"blobTierChangeTime": "2019-01-11T16:50:59+00:00",
"blobTierInferred": false,
"blobType": "BlockBlob",
"contentLength": 564,
"contentRange": null,
"contentSettings": {
"cacheControl": null,
"contentDisposition": null,
"contentEncoding": null,
"contentLanguage": null,
"contentMd5": "J46oaHVXow+85uEF58la/w==",
"contentType": "text/html"
},
"copy": {
"completionTime": null,
"id": null,
"progress": null,
"source": null,
"status": null,
"statusDescription": null
},
"creationTime": "2019-01-11T15:03:18+00:00",
"deletedTime": null,
"etag": "0x8D677E4F6791B3D",
"lastModified": "2019-01-11T16:50:59+00:00",
"lease": {
"duration": null,
"state": "available",
"status": "unlocked"
},
"pageBlobSequenceNumber": null,
"remainingRetentionDays": null,
"serverEncrypted": true
},
"snapshot": null
},
The documentation for the Azure CLI's storage blob list,表示它支持全局参数--query。
基于对文档的阅读,看来我应该能够执行以下查询,但随后没有任何结果(而且我知道有些项目很冷):
az storage blob list --container-name $web --account-name mystorageaccount --query 'properties[?blobTier == 'Cold']'
有人知道我在做什么错吗?
答案 0 :(得分:0)
我想出了我问题的答案。 The following article gave a bunch more examples on how to properly select and filter data.
结果,我能够提出导致预期行为的以下内容。
beforeMount(){
var that = this;
function importAll (r) {
r.keys().forEach(key => that.imgCache[key] = r(key));
}
importAll(require.context('../assets/flags/', true, /\.png$/));
},
computed: {
src(){
var key = `./flag-${this.country}.png`,
url = this.imgCache[key];
return url;
}
},
