在这个文件中，我创建了一个 JSON 文件。

This is my JSON.config { {
  "params":
  {
    "upload_location":"E:\\Ineuron Internship\\Automated ML\\AutoML\\uploads"


  },
}

在这个文件中，我编写了用于加载 JSON 文件的代码。

import json
from flask import request, Flask, render_template
import os
from werkzeug.utils import secure_filename
os.putenv('LANG', 'en_US.UTF-8')




os.putenv('LC_ALL', 'en_US.UTF-8')

with open('config.json','r')as E:
     params = json.load(E)



app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = params['upload_location']



@app.route("/", methods=['GET', 'POST'])
def home():
    return render_template('index.html')

@app.route("/uploader",methods = ['GET','POST'])
def uploader():
    if (request.method == 'POST'):
        f = request.files['file1']
        f.save(os.path.join(app.config['UPLOAD_FOLDER'],secure_filename(f.filename)))
        return "uploaded successfully"


if __name__ == "__main__":
    app.run(debug=True)

加载时出现此错误：JSON。解码器.JSONDecodeError：期望值：

或者有时当我添加一些东西时：JSON。decoder.JSONDecodeError：期望用双引号括起来的属性名称：

This is My ERROR:

据我所知，问题不在于您的代码，而在于您的 JSON 文件：

This is my JSON.config { {
  "params":
  {
    "upload_location":"E:\\Ineuron Internship\\Automated ML\\AutoML\\uploads"


  }, # The extra comma here means another key is meant to be present
}

要解决此问题，只需删除逗号：

This is my JSON.config { {
  "params":
  {
    "upload_location":"E:\\Ineuron Internship\\Automated ML\\AutoML\\uploads"


  }
}
