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。
答案 0 :(得分:3)
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);
