【问题描述】:
我从 Flask 开始。 我有以下 view.py
我的问题是关于路线 @app.route('/uploaded'...
from flask import render_template, jsonify, Flask, redirect, url_for, request
from app import app
import random
import os
from keras.applications.resnet50 import ResNet50
from keras.preprocessing import image
from keras.applications.resnet50 import preprocess_input, decode_predictions
import numpy as np
@app.route('/')
@app.route('/upload')
def upload_file2():
return render_template('index.html')
@app.route('/uploaded', methods = ['GET', 'POST'])
def upload_file():
if request.method == 'POST':
f = request.files['file']
path = os.path.join(app.config['UPLOAD_FOLDER'], f.filename)
model= ResNet50(weights='imagenet')
img = image.load_img(path, target_size=(224,224))
x = image.img_to_array(img)
x = np.expand_dims(x, axis=0)
x = preprocess_input(x)
preds = model.predict(x)
preds_decoded = decode_predictions(preds, top=3)[0]
print(decode_predictions(preds, top=3)[0])
f.save(path)
return render_template('uploaded.html', title='Success', predictions=preds_decoded, user_image=f.filename)
@app.route('/index')
def index():
return render_template('index.html', title='Home')
@app.route('/map')
def map():
return render_template('map.html', title='Map')
@app.route('/map/refresh', methods=['POST'])
def map_refresh():
points = [(random.uniform(48.8434100, 48.8634100),
random.uniform(2.3388000, 2.3588000))
for _ in range(random.randint(2, 9))]
return jsonify({'points': points})
@app.route('/contact')
def contact():
return render_template('contact.html', title='Contact')
在.html文件中,经过一些验证步骤后,我要求End Under上传一个文件(一张图片)。
然后在我下面的代码中,输入是图像,我希望输出结果,它必须显示在上传中。
但是,当我访问 localhost:5000 时,我无法访问 uploaded.html
URL 是否卡在我的 PHP 请求中(用于在我的 home.html 中上传文件的请求)
我从这个网站上阅读了许多关于类似问题的不同答案,但没有一个能解决我的问题。
提前致谢
index.html:
{% extends "layout.html" %}
{% block head %}
{{ super() }}

你在顶部有一个孤独的路由装饰器(
@app.route('/')),正常吗?
