为什么aspose.cells python via net下, 将Workbook对象保存至二进制流BytesIO报错

中文技术支持

创建一个 BytesIO 流对象

byte_stream = io.RawIOBase()

将工作簿保存到字节流中（指定保存格式）

workbook.save(stream=byte_stream, save_format=SaveFormat.XLSX) # 1 = XLSX 格式

Errors
RuntimeError: Proxy error(PyIOException): Exception was caused by unmanaged callback function error:
NotImplementedError

@zengweiyu,

我使用以下示例代码通过 .NET 的 Aspose.Cells for Python 测试了您的场景/案例，它运行良好，没有出现任何异常。我创建了一个工作簿，在工作表单元格中输入了一些值，将工作簿保存到字节 io 或流中。一切都运行良好。

import aspose.cells
from aspose.cells import Workbook, WorksheetCollection, Worksheet, CellsHelper, License, SaveFormat
import io


# Create a new workbook
workbook = Workbook()

# Access the first worksheet
worksheet = workbook.worksheets[0]

# Add "Hello, World!" to cell A1
worksheet.cells.get("A1").put_value("Hello, World!")

# Create an io.BytesIO stream
stream = io.BytesIO()

# Save the workbook to the stream in Xlsx format
workbook.save(stream, SaveFormat.XLSX)

# Reset the stream position for further use
stream.seek(0)

# Optional: Save the stream content to a file to verify (for demonstration)
with open("e:\\test2\\HelloWorld.xlsx", "wb") as file:
    file.write(stream.getvalue())

print("Excel workbook created and saved to stream successfully!")
