I am working on an angular and .NET Core application. I have to pass the file uploaded from angular to WEB API. My code is:
public async Task ImportDataScienceAnalytics(string authToken, IFormFile file)
{
var baseUrl = Import.GetBaseURL();
var client = new RestClientExtended(baseUrl + "algorithm/import");
var request = new RestRequest(Method.POST);
request.AddHeader("authorization", authToken);
string jsonBody = JsonConvert.SerializeObject(file);
request.AddJsonBody(jsonBody);
var response = await client.ExecutePostTaskAsync(request);
var result = response.Content;
}
Issue is that i get "No Attachment Found". I think the issue is because of IFormFile. How can i resolve this issue so that i can upload the file to web api.
It seems that you'd like to post uploaded file to an external API from your API action using RestClient
, you can refer to the following code snippet.
var client = new RestClient(baseUrl + "algorithm/import");
var request = new RestRequest(Method.POST);
request.AddHeader("authorization", authToken);
using (var ms = new MemoryStream())
{
file.CopyTo(ms);
var fileBytes = ms.ToArray();
request.AddFile("file", fileBytes, file.FileName, "application/octet-stream");
}
//...
Testing code of Import
action
public IActionResult Import(IFormFile file)
{
//...
//code logic here
You need to make following changes to the code. var baseUrl = Import.GetBaseURL();
var client = new RestClientExtended(baseUrl + "algorithm/import");
var request = new RestRequest(Method.POST);
byte[] data;
using (var br = new BinaryReader(file.OpenReadStream()))
data = br.ReadBytes((int)file.OpenReadStream().Length);
ByteArrayContent bytes = new ByteArrayContent(data);
MultipartFormDataContent multiContent = new MultipartFormDataContent
{
{ bytes, "file", file.FileName }
};
//request.AddHeader("authorization", authToken);
//string jsonBody = JsonConvert.SerializeObject(file);
//request.AddJsonBody(jsonBody);
/// Pass the multiContent into below post
var response = await client.ExecutePostTaskAsync(request);
var result = response.Content;
Do not forget to pass the variable multiContent into the post call.
