我想传递用户在我的python函数views.py中选择的图像的url，因为我的python函数将处理用户选择的图像。这是我的HTML命令如何将点击我的html文件的图像url传递给view.py中的python函数Django

这里是一个由用户选择必须在cv2.imread（）我怎样才能做到这一点对我的蟒蛇
def predict():
img = cv2.imread('C:/Users/HABITUS/Desktop/arvin files/download.jpg') #the url of the image selected must be here!!
img = cv2.resize(img, (600, 600))
enhancer = Image.fromarray(img)
enhancer = ImageEnhance.Contrast(enhancer)
enhanced = enhancer.enhance(1.5)
enhancer1 = ImageEnhance.Brightness(enhanced).enhance(1.3)
convert = scipy.misc.fromimage(enhancer1)
imgM = cv2.medianBlur(convert, 5)
# blurring and smoothening
kernel = np.ones((5, 5), np.uint8)
erosion = cv2.erode(imgM, kernel, iterations=1)
dilation = cv2.dilate(erosion, kernel, iterations=1)
blur = cv2.GaussianBlur(convert, (15, 15), 10)
grayscaled = cv2.cvtColor(imgM, cv2.COLOR_BGR2GRAY)
retval2, threshold2 = cv2.threshold(grayscaled, 200, 1, cv2.THRESH_BINARY_INV)
gaus = cv2.adaptiveThreshold(grayscaled, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 115, 1)
retval2, otsu = cv2.threshold(grayscaled, 140, 250, cv2.THRESH_BINARY + cv2.THRESH_OTSU)
backtorgb = cv2.cvtColor(threshold2, cv2.COLOR_GRAY2RGB)
mult = cv2.multiply(img, backtorgb)
edges = cv2.Canny(threshold2, 120, 50)
图像的功能？任何意见或帮助将不胜感激
我不阅读了Django 2.0。但这在django中是一个非常好的问题。我的想法是，你所描述的用例分为前端和后端。我确信这会产生一些分歧，但是Django并没有明确说明Django与JS交谈的框架。所以如果快速和肮脏的只是使用Django的形式。但是，如果对于更多的生产用例，我会使用js框架来监听哪个img是onClicked，然后将该帖子发送到django rest框架端点。 – sahutchi
