我一直在努力下载使用restsharp在线托管的简单pdf。我一直在玩代码超过一个小时,我得到的只是空对象结果。

使用GET在POSTMAN中轻松下载文件,但没有内容标题集,但仍然提供了什么?

以下是我一直在试验的noddy沙盒测试:

[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 Return a Stream

        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);

现在使用下载的数据填充流。

试试这个:

    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);
