发送MIME多部分请求(
multipart/form-data
),每个blob都是自己的FormData条目:
https://developer.mozilla.org/en-US/docs/Web/API/FormData/Using_FormData_Objects
Request.Content.ReadAsMultipartAsync
应用程序编程接口:
https://docs.microsoft.com/en-us/aspnet/web-api/overview/advanced/sending-html-form-data-part-2
您需要将控制器操作更改为不使用方法参数,而是从
Request
直接:
public async Task<HttpResponseMessage> PostFormData()
{
// Check if the request contains multipart/form-data.
if( !this.Request.Content.IsMimeMultipartContent() )
{
throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
}
// Temporarily write the request to disk (if you use `MultipartMemoryStreamProvider` your risk crashing your server if a malicious user uploads a 2GB+ sized request)
String root = this.Server.MapPath("~/App_Data");
MultipartStreamProvider provider = new MultipartFormDataStreamProvider(root);
try
{
// Read the form data and serialize it to disk for reading immediately afterwards:
await this.Request.Content.ReadAsMultipartAsync( provider );
// This illustrates how to get the names each part, but remember these are not necessarily files: they could be form fields, JSON blobs, etc
foreach( MultipartFileData file in provider.FileData )
{
Trace.WriteLine( file.Headers.ContentDisposition.FileName );
Trace.WriteLine( "Server file path: " + file.LocalFileName );
}
return this.Request.CreateResponse( HttpStatusCode.OK );
}
catch( System.Exception e )
{
return this.Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e);
}
}
