我正在 OSX 中构建一个 .net core 2.0 应用程序，它是一个 WebAPI 应用程序，当 API 端点被命中时，它会创建一个带有虚拟数据的 .xlsx。当我尝试运行它（dotnet run）时，我得到

System.UnauthorizedAccessException: Access to the path '/Users/myuser/projects/myproject' is denied. ---> System.IO.IOException: Permission denied

我尝试将它作为 sudo 运行并更改它正在写入的文件夹，但都没有帮助

// GET api/values/5
    [HttpGet("{id}")]
    public string Get(int id)
    {
        CreatePackage("./");
        return "value";
    }

    public void CreatePackage(string filePath)
    {
        using (SpreadsheetDocument package = SpreadsheetDocument.Create(filePath, SpreadsheetDocumentType.Workbook))
        {
            CreateParts(package);
        }
    }

    private void CreateParts(SpreadsheetDocument document)
    {
        WorkbookPart workbookPart = document.AddWorkbookPart();
        GenerateWorkbookPartContent(workbookPart);

        WorksheetPart worksheetPart = workbookPart.AddNewPart<WorksheetPart>("rId1");
        GenerateWorksheetPartContent(worksheetPart);
    }

    private void GenerateWorkbookPartContent(WorkbookPart workbookPart)
    {
        Workbook workbook = …

所以我正在编写一个从redis读取的节点应用程序,我想做一些返回数据库数量的查询,任何人都知道如何做到这一点.

所以现在基本上我所拥有的是一种获取数据库中所有键的方法,但我想要更高级别,我想迭代所有数据库,然后获取所有键.这是获取当前数据库的所有密钥的代码.

const client = redis.createClient({host: "127.0.0.1", port: 6379});
client.multi()
    .keys('*', function (err, replies) {
        console.log("MULTI got " + replies.length + " replies");
        let dbs = [replies];
        let dbData = {};
        replies.forEach(function (reply, index) {
            client.get(reply, function (err, data) {
                console.log(reply + " " +data);
            });
        });

    })
    .exec(function (err, replies) { });
