netframework转core时文件响应流问题
做将framework webapi项目转成netcore平台上的webapi项目时,发现原来的返回文件响应流在netcore平台下失效。代码如下,返回pdf文件响应流,供前端显示
/// <summary> /// 根据pdf的预览id获取预览的pdf /// </summary> /// <param name="Id"></param> /// <returns></returns> [HttpGet] [Route("GetPreviewPdf")] public HttpResponseMessage GetPreviewPdf(Guid Id) { string pdfBase64String = _cacheManager.Get<string>(Id.ToString()); var response = new HttpResponseMessage(); if (!string.IsNullOrEmpty(pdfBase64String)) { byte[] pdfArray = Convert.FromBase64String(pdfBase64String); response.StatusCode = System.Net.HttpStatusCode.OK; response.Content = new ByteArrayContent(pdfArray); response.Content.Headers.ContentType = MediaTypeHeaderValue.Parse(MimeTypes.ApplicationPdf); } else { response.StatusCode = System.Net.HttpStatusCode.Gone; } return response; }
不记得参考网址了,反正是stackoverflow上面了。需要在netcore项目中配置支持原有MVC的功能。
1、添加Nuget引用
2、在startup类中添加配置
public IServiceProvider ConfigureServices(IServiceCollection services) { services.AddMvc().AddWebApiConventions(); }
