我需要將我上傳的圖像傳遞給燒瓶。 html 頁面上傳了圖像，但我無法將該圖像作為請求傳輸到燒瓶。 我用它來進行圖像預測，但無法獲取圖像。這是我的燒瓶代碼import numpy as npfrom flask import Flask, request, jsonify, render_templateimport numpyfrom PIL import Imagefrom keras.models import load_modelapp = Flask(__name__)model = load_model('traffic_classifier.h5')classes = { 1:'Speed limit (20km/h)', 2:'Speed limit (30km/h)', 3:'Speed limit (50km/h)', 4:'Speed limit (60km/h)', 5:'Speed limit (70km/h)', 6:'Speed limit (80km/h)', 7:'End of speed limit (80km/h)', 8:'Speed limit (100km/h)', 9:'Speed limit (120km/h)', 10:'No passing', 11:'No passing veh over 3.5 tons', 12:'Right-of-way at intersection', 13:'Priority road', 14:'Yield', 15:'Stop', 16:'No vehicles', 17:'Veh > 3.5 tons prohibited', 18:'No entry', 19:'General caution', 20:'Dangerous curve left', 21:'Dangerous curve right', 22:'Double curve', 23:'Bumpy road', 24:'Slippery road', 25:'Road narrows on the right', 26:'Road work', 27:'Traffic signals', 28:'Pedestrians', 29:'Children crossing', 30:'Bicycles crossing', 31:'Beware of ice/snow', 32:'Wild animals crossing', 33:'End speed + passing limits', 34:'Turn right ahead', 35:'Turn left ahead', 36:'Ahead only', 37:'Go straight or right', 38:'Go straight or left', 39:'Keep right', 40:'Keep left', 41:'Roundabout mandatory', 42:'End of no passing', 43:'End no passing veh > 3.5 tons' }

<form method="post" action="{{ url_for('') }}" enctype="multipart/form-data">
def upload_image():
try:
if request.method == 'POST':
ALLOWED_EXTENSIONS = [".png", ".jpg", ".jpeg", ".gif"]
file = request.files['image']
if file and any(split_filename(file.filename)[1] == s for s in ALLOWED_EXTENSIONS):
folder = app.config['UPLOAD_FOLDER']

'%Y\\%m\\')
if not os.path.exists(os.path.join(folder + pathName)):

filename = str(uuid.uuid4()) + split_filename(file.filename)[1]
file.save(os.path.join(folder + pathName, filename))
path = pathlib.PureWindowsPath(pathName + filename).as_posix()
return url_for('main.get_file', path=path, _external=True)
else:
return 'Please Choose PNG, JPG, JPEG, GIF Image, Not ' + split_filename(file.filename)[1], 404
except Exception as error:
return error.__str__()
@mn.route('/file/<path:path>', methods=['GET'])
def get_file(path):
try:
return send_file(os.path.join(app.config['UPLOAD_FOLDER'], path))
except :
return send_file(os.path.join(app.config['UPLOAD_FOLDER'], '404.png'))
這是我的代碼
