Question

我有一个URL（来自客户端的实时源的URL），当我在浏览器中点击时返回xml响应。我已将其保存在文本文件中，其大小为8 MB。

现在我的问题是我需要将此响应保存在服务器驱动器上的xml文件中。从那里我将在数据库中插入此。并且需要使用http-client或c＃.net 4.5

的rest-sharp库使用代码进行请求

我不确定我应该为上述情况做些什么。任何身体都可以向我推荐一些东西

Answer 1

使用RestSharp，它就在readme：

中

var client = new RestClient("http://example.com");
client.DownloadData(request).SaveAs(path);

使用HttpClient，它会更复杂一些。看看this blog post。

另一种选择是Flurl.Http（免责声明：我是作者）。它使用了引擎盖下的HttpClient，并提供了一个流畅的界面和许多方便的帮助方法，包括：

await "http://example.com".DownloadFileAsync(folderPath, "foo.xml");

获取NuGet。

Answer 2

看来SaveAs已经停产。你可以试试这个

var client = new RestClient("http://example.com")    
byte[] response = client.DownloadData(request);
File.WriteAllBytes(SAVE_PATH, response);

Answer 3

阅读时不要将文件保存在内存中。直接写入磁盘。

var tempFile = Path.GetTempFileName();
using var writer = File.OpenWrite(tempFile);

var client = new RestClient(baseUrl);
var request = new RestRequest("Assets/LargeFile.7z");
request.ResponseWriter = responseStream =>
{
    using (responseStream)
    {
        responseStream.CopyTo(writer);
    }
};
var response = client.DownloadData(request);

Answer 4

如果您需要异步版本

var request = new RestRequest("/resource/5", Method.GET);
var client = new RestClient("http://example.com")    
var response = await client.ExecuteTaskAsync(request);
if (response.StatusCode != HttpStatusCode.OK)
            throw new Exception($"Unable to download file");
response.RawBytes.SaveAs(path);

Answer 5

将以下NuGet软件包添加到当前系统中

dotnet添加软件包RestSharp

使用承载身份验证

int index = 0;
foreach (string[] item in dataList)       
 {
   for (int i = 0; i < item.Length; i++)
   {
      Console.WriteLine("Column {0} details: {1}", index+1, item[i]);
   }
        index++;
}

使用基本身份验证

// Download file from 3rd party API
[HttpGet("[action]")]
public async Task<IActionResult> Download([FromQuery] string fileUri)
{
  // Using rest sharp 
  RestClient client = new RestClient(fileUri);
  client.ClearHandlers();
  client.AddHandler("*", () => { return new JsonDeserializer(); });
  RestRequest request = new RestRequest(Method.GET);
  request.AddParameter("Authorization", string.Format("Bearer " + accessToken), 
  ParameterType.HttpHeader);
  IRestResponse response = await client.ExecuteTaskAsync(request);
  if (response.StatusCode == System.Net.HttpStatusCode.OK)
  {
    // Read bytes
    byte[] fileBytes = response.RawBytes;
    var headervalue = response.Headers.FirstOrDefault(x => x.Name == "Content-Disposition")?.Value;
    string contentDispositionString = Convert.ToString(headervalue);
    ContentDisposition contentDisposition = new ContentDisposition(contentDispositionString);
    string fileName = contentDisposition.FileName;
    // you can write a own logic for download file on SFTP,Local local system location
    //
    // If you to return file object then you can use below code
    return File(fileBytes, "application/octet-stream", fileName);
  }
}
