Django Rest框架文件上传(Django Rest Framework File Upload)

 我使用Django Rest Framework和AngularJs来上传文件。 我的视图文件看起来像这样。  
class ProductList(APIView):
    authentication_classes = (authentication.TokenAuthentication,)
    def get(self,request):
        if request.user.is_authenticated(): 
            userCompanyId = request.user.get_profile().companyId
            products = Product.objects.filter(company = userCompanyId)
            serializer = ProductSerializer(products,many=True)
            return Response(serializer.data)

    def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(data=request.DATA)
 
 作为最后一行的post方法应该返回所有的数据，应该在那里写什么，或者如何检查那里是否有任何请求.FILES，以及如何序列化文件或怎样使用Parser？ 请帮忙.. 

I am using Django Rest Framework and AngularJs to upload a file. My view file looks like this: 
class ProductList(APIView):
    authentication_classes = (authentication.TokenAuthentication,)
    def get(self,request):
        if request.user.is_authenticated(): 
            userCompanyId = request.user.get_profile().companyId
            products = Product.objects.filter(company = userCompanyId)
            serializer = ProductSerializer(products,many=True)
            return Response(serializer.data)

    def post(self,request):
        serializer = ProductSerializer(data=request.DATA, files=request.FILES)
        if serializer.is_valid():
            serializer.save()
            return Response(data=request.DATA)
 
As the last line of post method should return all the data, I have several questions: 
 
 how to check if there is anything in request.FILES? 
 how to serialize file field? 
 how should I use parser?

 Facebook有一个Swift SDK，你可能会发现它比Objective-C（他们刚刚称之为iOS）更容易使用。 试着查看这里的文档：  
 https://developers.facebook.com/docs/swift  
 另外，请按照（其他）iOS SDK中描述的步骤开始：  
 https://developers.facebook.com/docs/ios/getting-started/  
 这是我可以开始工作的最小应用程序委托（请注意，Swift SDK缺少iOS SDK中存在的FB前缀）：  
import UIKit
import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
        SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
        return true
    }

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
    }

}
 
 并确保在Info.plist添加所有必需的密钥，否则您将无法获得身份验证。 

Facebook has a Swift SDK you might find easier to use than the Objective-C one (which they just call iOS). Try looking around the documentation here: 
https://developers.facebook.com/docs/swift 
Also, follow the steps described in the (other) iOS SDK to get started: 
https://developers.facebook.com/docs/ios/getting-started/ 
This is the minimal app delegate I could get to work (notice the Swift SDK is missing the FB prefixes that exist in the iOS SDK): 
import UIKit
import FacebookCore

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {
        SDKApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
        return true
    }

    func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
        return SDKApplicationDelegate.shared.application(app, open: url, options: options)
    }

}
 
And be sure to add all the required keys in your Info.plist or else you won't get authentication to work at all.
