swift 如何上传图片到django 的后台服务器

来源：互联网发布：网络机顶盒ir接口编辑：程序博客网时间：2024/05/18 16:37

本人用 django 做了一个后台,想作为移动端的后台使用,奈何一直被一个问题困扰,上传字符串很轻松的就实现了,但是上传文件或者图片总是失败,困扰了日之后终于解决了,原来一直以来方向都搞错了,一直认为是 django 的代码问题,后来才发现是 swift 方面的问题.不多说直接上代码.

swift :

let p1 = "p1"

let image : UIImage =UIImage(named:"屏幕快照 2016-09-02下午12.40.08.png")!

let imageData = UIImagePNGRepresentation(image)

//后台其他字段所需要的参数,要和后台一一对应

let parameters = [p1:"zhaobin"]

//fileName 可以自定义,显示在后台图片的名字

Alamofire.upload(.POST,"http://127.0.0.1:8000/polls/home", multipartFormData: {

multipartFormData in

multipartFormData.appendBodyPart(data: imageData!, name:"p2", fileName:"zhaobin.png", mimeType:"image/png")

for (key, value)in parameters {

multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key )

}

}, encodingCompletion: {

encodingResult in

switch encodingResult {

case .Success(let upload,_,_):

upload.responseJSON {

response in

debugPrint(response)

}

case .Failure(let encodingError):

print(encodingError)

}

})

django :

def homeApp(request):    p1    = request.POST.get('p1')

// 前台上传的文件    image = request.FILES.get('p2')

// ExamInfo  model 中定义的 class    test = ExamInfo()    test.level = image    test.name = p1    test.save()

接收 html :

class NormalUserForm(forms.Form):  username = forms.CharField()  headImg  = forms.FileField()def registerNormalUser(request):  if request.method == "POST":    uf = NormalUserForm(request.POST,request.FILES)    if uf.is_valid():      # get the info of the form  cleaned_data :处理或得到的数据,让 username 和 uf 获得数据类型一致      username = uf.cleaned_data['username']      headImg = uf.cleaned_data['headImg']      # write in database      normalUser = NormalUser()      normalUser.username = username      normalUser.headImg = headImg      normalUser.save()      return HttpResponse('Upload Succeed!')  else:    uf = NormalUserForm()  return render(request,'polls/register.html',{'uf':uf})
