解决办法：引入csrf_exempt包：

from django.views.decorators.csrf import csrf_exempt

然后增加装饰器：

@csrf_exempt
def register(request):  
    request.encoding='utf-8'
    if request.GET:
        return render(request,'register.html')
    elif request.POST:
        dictData = request.POST
        context = {}
        print(dictData)
