1、如果是以文件的形式上传，这样接收：
public IHttpActionResult getTest2()
{
string id = HttpContext.Current.Request["id"];
string name = HttpContext.Current.Request["name"];
HttpFileCollection files = HttpContext.Current.Request.Files;
foreach (string key in files.AllKeys)
{
HttpPostedFile file = files[key];//file.ContentLength文件长度
if (string.IsNullOrEmpty(file.FileName) == false)
file.SaveAs(HttpContext.Current.Server.MapPath("~/App_Data/") + file.FileName);
}
return Ok("success2");
}
2、如果是以文件流的形式上传（如从Android端使用retrofit上传多文件），这样接收：
[HttpPost]
public async Task<string> InsertPics()
{ var root = HttpContext.Current.Server.MapPath("~/App_Data");
var provider = new MultipartFormDataStreamProvider(root);
await Request.Content.ReadAsMultipartAsync(provider);
var httpContents = provider.Contents;
int i = 0;
foreach (var content in httpContents)
{
var suffix = content.Headers.ContentDisposition.Name.Trim('"').Split('.').Last();
var arrayAsync = content.ReadAsByteArrayAsync();
FileStream stream = new FileStream(root + "\\" + i++ + "." + suffix, FileMode.CreateNew);
stream.Write(arrayAsync.Result, 0, arrayAsync.Result.Length);
stream.Close();
}
return null;
}
