如何在asp.net core 2.0中实现范围请求/响应?

How to implement the range request / response in asp.net core 2.0?

var fileStream = await this.amazonS3Service.Open(
               request.FileName,
               path,
               cancellationToken);

return new FileStreamResult(fileStream, this.GetContentType(request.FileName));

推荐答案

iOS认为是流范围和内容长度标头

What iOS considered to be is stream range and content-length header

在dotnet Core 2.1中添加了对范围的支持

In dotnet Core 2.1 was added support for Ranges

将文件构造函数与enableRangeProcessing一起使用

Use File constructor with enableRangeProcessing

 return File(fileStream, this.GetContentType(request.FileName), true);
