asp.net - 失败 - 在 Chrome 中获取 Zip 文件时出现网络错误

Question

我正在通过 Ionic.Zip.dll 创建一个 zip像这样(ASP.NET，C#):

zip.AddEntry("Document.jpeg", File.ReadAllBytes("Path");

我想像这样下载它:

Response.Clear();
Response.BufferOutput = false;
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=SuppliersDocuments.zip";
zip.Save(Response.OutputStream);
Response.Close();

我通过 Firefox 和 Chrome 在 localhost 中测试了这段代码，它运行正常。但是当我在主机中测试此代码时，出现此错误:

Failed - network error

我的代码有错吗？

我在转发 SSRS 报告时遇到了类似的问题。接受@Arvin的建议，我做了以下事情:

private void CreateReport(string ReportFormat)
{
    ReportViewer rview = new ReportViewer();

    // (setup report viewer object)

    // Run report
    byte[] bytes = rview.ServerReport.Render(ReportFormat, deviceInfo, out mimeType, out encoding, out extension, out streamids, out warnings); 

    // Manually create a response
    Response.Clear();
    Response.ContentType = mimeType;
    Response.AddHeader("Content-disposition", string.Format("attachment; filename={0}.{1}", fileName, extension));

    // Ensure the content size is set correctly
    Response.AddHeader("Content-Length", bytes.Length.ToString()); // <- important

    // Write to the response body
    Response.OutputStream.Write(bytes, 0, bytes.Length);

    // (cleanup streams)
}

修复是添加 Content-Length header 并将其设置为来自报告服务的字节数组的大小。
