Question

我一直在拉着我的头发试图让它发挥作用。这就是我想要实现的目标：

使用lucene.Net获取搜索功能
在azure上主持

问题：

我使用本教程Lucene.Net ultra fast search for MVC or WebForms site => made easy!开始使用，当我从localdb检索到我的本地磁盘中创建索引文件并随后调用rest方法来执行搜索时，它完美地工作。

现在我正在尝试将部分代码转换为引用blob。原来是这样的：

private static string _luceneDir =Path.Combine(HttpContext.Current.Request.PhysicalApplicationPath, "lucene_index");
private static FSDirectory _directoryTemp;
private static FSDirectory _directory {
get {
    if (_directoryTemp == null) _directoryTemp = FSDirectory.Open(new DirectoryInfo(_luceneDir));
    if (IndexWriter.IsLocked(_directoryTemp)) IndexWriter.Unlock(_directoryTemp);
    var lockFilePath = Path.Combine(_luceneDir, "write.lock");
    if (File.Exists(lockFilePath)) File.Delete(lockFilePath);
    return _directoryTemp;
}}

我把它更改为：

private static AzureDirectory azureDirectory = new AzureDirectory(CloudStorageAccount.Parse(CloudConfigurationManager.GetSetting("StorageConnectionString")),"SearchCatalog");
private static AzureDirectory _directoryTemp;


        private static AzureDirectory _directory
        {
            get
            {
                // if (_directoryTemp == null) _directoryTemp = FSDirectory.Open(new DirectoryInfo(_luceneDir));
                if (_directoryTemp == null) _directoryTemp = azureDirectory;
                if (IndexWriter.IsLocked(_directoryTemp)) IndexWriter.Unlock(_directoryTemp);
                return _directoryTemp;
            }
        }

我拿走了最后两行，因为我不知道如何在azure中获取blobl存储的文件路径，而且根据我的理解，这是不可能的。

现在发生的是blob中的容器被创建，但是没有创建索引文件，我得到了一个http 404错误。详细错误：

}

提前谢谢，真的很丢失我做错了。

请删除以下代码

     if (IndexWriter.IsLocked(_directoryTemp)) IndexWriter.Unlock(_directoryTemp);

删除上面的代码后，它可以工作。这是我身边的截图：

以下是我的代码：

 private static AzureDirectory azureDirectory = new AzureDirectory(CloudStorageAccount.Parse("DefaultEndpointsProtocol=https;AccountName=jastorage1;AccountKey=***"),"sample"

        private static AzureDirectory _directoryTemp;
        private static AzureDirectory _directory
        {
            get
            {
                // if (_directoryTemp == null) _directoryTemp = FSDirectory.Open(new DirectoryInfo(_luceneDir));
                if (_directoryTemp == null) _directoryTemp = azureDirectory;
               // if (IndexWriter.IsLocked(_directoryTemp)) IndexWriter.Unlock(_directoryTemp);
                _directoryTemp.ClearLock("write.lock");
                return _directoryTemp;
            }
        }

使用Azuredirectory在Azure Blob中创建lucene索引时出错
