无法使用RestSharp下载pdf? [英] Cannot download a pdf with RestSharp?

问题描述

我一直在努力下载使用restsharp在线托管的简单pdf文件.我已经在代码上玩了一个多小时，而我得到的只是空对象结果.

I have been struggling to download a simple pdf hosted online using restsharp. I have been playing around with the code for over an hour and all I get are null object results.

使用GET轻松在POSTMAN中下载文件，并且没有设置内容标头，但是仍然可以提供什么?

The file downloads easily in POSTMAN using a GET and no content header set but still what gives?

以下是我一直在尝试的点头沙盒"测试:

Below is the noddy sandbox test I have been experimenting around with:

[TestFixture]
public class Sandbox
{
    [Test]
    public void Test()
    {
        var uri = "https://www.nlm.nih.gov/mesh/2018/download/2018NewMeShHeadings.pdf";
        var client = new RestClient();
        var request = new RestRequest(uri, Method.GET);
        //request.AddHeader("Content-Type", "application/octet-stream");
        byte[] response = client.DownloadData(request);
        File.WriteAllBytes(@"C:\temp\1.pdf", response);
    }
}

更新: 返回流

        var baseUri = "https://www.nlm.nih.gov/mesh/2018/download/";
        var client = new RestClient(baseUri);
        var request = new RestRequest("2018NewMeShHeadings.pdf", Method.GET);
        request.AddHeader("Content-Type", "application/octet-stream");
        var tempFile = Path.GetTempFileName();
        var stream = File.Create(tempFile, 1024, FileOptions.DeleteOnClose);
        request.ResponseWriter = responseStream => responseStream.CopyTo(stream);
        var response = client.DownloadData(request);

现在，已用下载的数据填充流.

The stream is now populated with the downloaded data.

推荐答案

尝试一下:

    var uri = "https://www.nlm.nih.gov/mesh/2018/download/";
    var client = new RestClient(uri);
    var request = new RestRequest("2018NewMeShHeadings.pdf", Method.GET);
    //request.AddHeader("Content-Type", "application/octet-stream");
    byte[] response = client.DownloadData(request);
