在openrasta中的响应流上编写PDF内容

Question

我想在Iframe中呈现pdf。因此，如果我向http://localhost/pdf/2发出GET请求，它应该在响应流中返回PDF内容。另一种方法是将用户重定向到我不想做的PDF文件的完整URL。

提前致谢

您可以使用InMemoryFile和InMemoryDownloadableFile类。 一个例子：

private class AttachmentFile : InMemoryDownloadableFile
    {
        public AttachmentFile(byte[] file, string filename, string contenttype)
        {
            OpenStream().Write(file, 0, file.Length);
            this.FileName = filename;
            this.ContentType = new MediaType(contenttype);
        }
    }

    private class InlineFile : InMemoryFile
    {
        public InlineFile(byte[] file, string filename, string contenttype)
        {
            OpenStream().Write(file, 0, file.Length);
            this.FileName = filename;
            this.ContentType = new MediaType(contenttype);
        }
    }

    [HttpOperation(HttpMethod.GET)]
    public object Get(string filename)
    {

            bool inline = false; //server attachments inline or as download 
            try
            {
                inline = Convert.ToBoolean(Params["INLINE"]);
            }
            catch { }

            string contenttype = set contentttype...
            byte[] attachment = read file....

            if (inline)
                return new InlineFile(attachment, filename, contenttype);
            else return new AttachmentFile(attachment, filename, contenttype);   
        }
        else return new OperationResult.Forbidden();
    }
