Azure blob 存储 - findBlobsByTags 总是失败并出现错误 Error parsing query at or near character position 1: unexpected '1'

Question

我正在使用 Azure Blob 存储。在持久化 blob 的同时，我也持久化了索引标签。当我通过 Microsoft Azure 存储资源管理器下载 blob 时，我能够看到索引标签。以编程方式，我正在尝试过滤标签（使用 azure-storage-blob 版本 12.15.0）

我正在使用这个 api 从数据库中获取详细信息 - findBlobsByTags

这是我正在尝试的代码

    FindBlobsOptions findByTags = new FindBlobsOptions(searchExpression));
    findByTags.setMaxResultsPerPage(100);
    PagedIterable<TaggedBlobItem> blobsByTags = blobContainerClient.findBlobsByTags(findByTags, Duration.ofSeconds(30), Context.NONE);

我试过以下查询

 1.   String searchExpression = "where=@container = 'container-name' AND \"field\" = \'value\'";
 2. String searchExpression = "where=field=value";
 3. String searchExpression = "where=\"field\" =\'value\'";
     String escapeJava = StringEscapeUtils.escapeJava(searchExpression);
 4. String searchExpression = "&where=\"trackingId\"=\'TA00965650\'";

我遇到了这个异常。

从异常日志看来，我传递给 findBlobsByTags 方法的查询在解析时存在问题。请让我知道我做错了什么。如果有一些escaping/encoding需要完成

如评论中所述，请从您的搜索表达式中删除 where=。文档似乎不正确。您可能想在这里创建一个问题：https://github.com/Azure/azure-sdk-for-java/issues 以便更正文档。

您可以在此处查看工作代码：https://github.com/Azure/azure-sdk-for-java/blob/azure-storage-blob_12.16.0/sdk/storage/azure-storage-blob/src/test/java/com/azure/storage/blob/ContainerAPITest.groovy。
