推荐答案
尝试如下所示的代码.
public ActionResult Index(PublishPost post, HttpPostedFileBase file)
{
var apiURL = "http://test.sa.com/rest/social/update/1161/upload?access_token=6fWV564kj3drlu7rATh8="
using (HttpClient client = new HttpClient())
{
using (var content = new MultipartFormDataContent())
{
byte[] fileBytes = new byte[file.InputStream.Length + 1];
file.InputStream.Read(fileBytes, 0, fileBytes.Length);
var fileContent = new ByteArrayContent(fileBytes);
fileContent.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("attachment") { FileName = file.FileName };
content.Add(fileContent);
var result = client.PostAsync(apiURL, content).Result;
if (result.StatusCode == System.Net.HttpStatusCode.OK)
{
return new
{
code = result.StatusCode,
message = "Successful",
data = new
{
success = true,
filename = file.FileName
}
};
}
else
{
return new
{
code = result.StatusCode,
message = "Error"
};
}
}
}
}
