Dify version

1.8.0

Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

The code is as follows

class AsrTool(Tool):
    def _invoke(self, tool_parameters: dict[str, Any]) -> Generator[ToolInvokeMessage]:
        file :File = tool_parameters.get("file")
        with open("output.bin", "wb") as f:
            f.write(file.blob)

✔️ Expected Behavior

Can get file.blob

❌ Actual Behavior

In fact, file.blob cannot be obtained because the obtained file url does not contain the ip domain name, resulting in an execution error of httpx.get(self.url) in the File.blob() method
