from flask import Flask  
from flask import request
from flask import redirect
from flask import jsonify
import json

app = Flask(__name__)
@app.route('/api/hello', methods=['GET'])


def start():
  return json.dumps({
    'code': '0'
  })

if __name__ == '__main__':
  app.run(host='0.0.0.0', port=80)

关键是这里设置80入方向的安全组配置

然后访问:
ip/api/hello就成功了
