Python Flask CORS 问题

  • 772

处理请求时出错

来自外部的请求被阻止：单一来源策略禁止读取 https://my.server.name:5000/postmethod处的远程资源。（原因：CORS 请求失败）。状态码：（空）。

服务器代码

import socket
from flask import Flask,render_template,request,jsonify
from flask_cors import CORS
host = socket.gethostname()
app = Flask(__name__)
CORS(app)

@app.route('/postmethod', methods=['POST'])

def get_post_javascript_data():
    data = request.get_json()
    data = jsonify(data)
    data.headers.add('Access-Control-Allow-Origin','*')
    return data

if __name__ == "__main__":
    app.run(host=host,ssl_context='adhoc')

javascript代码

 $.post( "https://my.server.name:5000/postmethod", {
        encryption: JSON.stringify(value_post)});

如果我在浏览器中访问https://my.server.name:5000/postmethod，则会收到安全风险错误。错误代码：SEC_ERROR_UNKNOWN_ISSUER。单击“接受风险并继续”。并且只有在请求正常发送之后。如何解决？

    都想通了。需要制作密钥和证书文件

    import json
import socket
from flask import Flask,request,jsonify

host = socket.gethostname()
app = Flask(__name__)

@app.route('/postmethod', methods=['POST'])
def get_post_javascript_data():
    data = request.form
    data = jsonify(data)
    data.headers.add('Access-Control-Allow-Origin','*')
    with open('user_settings.json','w') as f:
        json.dump(request.form,f,indent=4,ensure_ascii=False)
    return data

if __name__ == "__main__":
    app.run(host=host,ssl_context=('root_ca.crt','root_ca.key'))
