Python 从应用程序向服务器发送图像时出错

从Swift应用程序向Django服务器发送图像时出错。 我正在制作Swift应用程序，我想在我的应用程序中制作一个系统，将图像上传到我的Django服务器。因此，在这段时间，当我运行Xcode的emulator（它是iPhone的emulator）时，我选择了图像，然后我按下“发送”按钮，将图像发送到服务器，我想将图像发送到我的服务器。但是错误发生了。 回溯（在Xcode中）是

我在网上读到这个错误，我认为这个错误是由错误的url引起的。所以我认为url

let myUrl=NSURL（字符串：http://127.0.0.1:8000/accounts/upload/post");
在斯威夫特，这是错误的。
但我认为这是正确的。
我在Django Server中编写了Server/accounts/views.py的代码

from django.contrib.auth.forms import AuthenticationForm
from django.contrib.auth.decorators import login_required
from django.http import HttpResponse
from django.shortcuts import render, redirect
from django.views.decorators.http import require_POST
from .forms import RegisterForm
from django.contrib.auth import authenticate, login
from .models import Post
from .forms import UserImageForm
from .models import ImageAndUser

def index(request):
    context = {
        'user': request.user,
    }
    return render(request, 'registration/accounts/index.html', context)

@login_required
def profile(request):
    context = {
        'user': request.user,
    }
    return render(request, 'registration/accounts/profile.html', context)

def regist(request):
    form = RegisterForm(request.POST or None)
    context = {
        'form': form,
    }
    return render(request, 'registration/accounts/regist.html', context)

def index(request):
    context = {
        'user': request.user,
    }
    return render(request, 'registration/accounts/index.html', context)


@login_required
def profile(request):
    context = {
        'user': request.user,
    }
    return render(request, 'registration/accounts/profile.html', context)

def regist(request):
    form = RegisterForm(request.POST or None)
    context = {
        'form': form,
    }
    return render(request, 'registration/accounts/regist.html', context)

@require_POST
def regist_save(request):
    form = RegisterForm(request.POST)
    if form.is_valid():
        user = form.save()
        login(request, user)
        context = {
            'user': request.user,
        }
        return redirect('profile')


    context = {
        'form': form,
    }
    return render(request, 'registration/accounts/regist.html', context)

@login_required
def photo(request):
    d = {
        'photos': Post.objects.all(),
    }
    return render(request, 'registration/accounts/profile.html', d)


def upload(request, p_id):
    form = UserImageForm(request.POST or None)
    d = {
        'p_id': p_id,
        'form':form,
    }
    return render(request, 'registration/accounts/photo.html', d)


def upload_save(request):

    photo_id = request.POST.get("p_id", "")

    if (photo_id):
        photo_obj = Post.objects.get(id=photo_id)
    else:
        photo_obj = Post()

    files = request.FILES.getlist("files[]")
    photo_obj.image = files[0]
    # photo_obj.image2 = files[1]
    # photo_obj.image3 = files[2]

    photo_obj.save()
    # return render(request, "registration/accounts/photo.html")

    photos = Post.objects.all()
    context = {
        'photos': photos,
    }
    return render(request, 'registration/accounts/photo.html', context)

def kenshinresults(request):
    d = {
        'results': results,
    }
    return render(request, 'registration/accounts/kenshin_result.html', d)

def tc(request):
    tcresults = ImageAndUser.objects.filter(user=request.user).order_by('id').last()
    d = {
        'tcresults': tcresults,
    }
    return render(request, 'registration/accounts/tc.html', d)

我在Server/accounts/url.py中编写了代码

from django.conf.urls import url
from . import views
from django.contrib.auth.views import login, logout
from django.views.generic import TemplateView

urlpatterns = [
    url(r'^login/$', login,
        {'template_name': 'registration/accounts/login.html'},
        name='login'),
    url(r'^logout/$', logout, name='logout'),
    url(r'^regist/$', views.regist,name='regist' ),
    url(r'^regist_save/$', views.regist_save, name='regist_save'),
    url(r'^profile/$', views.profile, name='profile'),
    url(r'^photo/$', views.photo, name='photo'),
    url(r'^upload/(?P<p_id>\d+)/$', views.upload, name='upload'),
    url(r'^upload_save/$', views.upload_save, name='upload_save'),
    url(r'^kenshinresults$', TemplateView.as_view(template_name='registration/accounts/kenshin_result.html'),
        name='kenshinresults'),
    url(r'^tcresults$', views.tc,name='tcresults'),
]

怎么了？不是服务器的url错误吗？
您正在将图像发送到路径
/accounts/upload/post
，但没有定义与该路径匹配的url

您的意思可能是
/accounts/upload\u save/
？

你能更新图像拾取和上传到服务器的代码吗？你能更新图像拾取和上传到服务器的代码吗？你的说法是对的，所以我写了类似let myUrl=NSURL（字符串：“这一次，我犯了一个错误。我更新了我的问题，所以如果你知道什么，请告诉我。你的说法是对的，所以我写了url，比如让myUrl=NSURL（字符串）：“这一次，我犯了一个错误。我更新了我的问题，所以如果你知道什么，请告诉我。”。
