.Net Core app無法將文件寫入OSX的任何文件夾

Question

我正在OSX中構建一個.net核心2.0應用程序，它是一個WebAPI應用程序，當命中API端點時會創建帶有虛擬數據的.xlsx。 當我嘗試運行它（dotnet運行）時，我得到了

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

我已經嘗試將其作為sudo運行並更改它正在寫入的文件夾，但都沒有幫助

// 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 = new Workbook();
        workbook.AddNamespaceDeclaration("r", "http://schemas.openxmlformats.org/officeDocument/2006/relationships");

        Sheets sheets = new Sheets();
        Sheet sheet = new Sheet() { Name = "Sheet", SheetId = (UInt32Value)1U, Id = "rId1" };
        sheets.Append(sheet);

        workbook.Append(sheets);
        workbookPart.Workbook = workbook;
    }

    private void GenerateWorksheetPartContent(WorksheetPart worksheetPart)
    {
        Worksheet worksheet = new Worksheet();
        SheetData sheetData = new SheetData();

        Row row = new Row();
        Cell cell = new Cell() { CellReference = "A1", DataType = CellValues.InlineString };
        InlineString inlineString = new InlineString();
        Text text = new Text();
        text.Text = "hello";
        inlineString.Append(text);
        cell.Append(inlineString);
        row.Append(cell);

        sheetData.Append(row);
        worksheet.Append(sheetData);
        worksheetPart.Worksheet = worksheet;
    }

這是該類的主要部分，我正在項目文件夾中創建文件（現在）。 我看到有關為CLI的所有文件提供讀寫權限的帖子，但這似乎並不理想。 我也看到了關於在文件上設置屬性的問題，但這是OpenXml電子表格創建方法，據我所知，它沒有任何關於設置文件權限的東西（無論如何它都需要在文件夾中）

任何幫助將非常感激

Answer 1

我想通了，我發送的文件路徑是文件路徑而不是文件路徑，問題解決了

[HttpGet("{id}")]
public string Get(int id)
{
    CreatePackage("./testfile.xlsx");
    return "value";
}
