Question

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('/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')
        @app.route('/')
        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上传文件（图像）。

然后在下面的代码中，输入是图像，我希望输出结果，该结果必须显示在上载的页面中。

但是，当我访问localhost：5000时，我无法访问uploaded.html

错误：

127.0.0.1--[25 / Sep / 2019 19:33:26]“ POST /upload.php HTTP / 1.1” 404-

对于类似的问题，我从该站点上读取了许多不同的答案，但没有一个能解决我的问题。

预先感谢
