我正在使用rasa chatbot,并且正在尝试调用操作端点api。但是我遇到了错误:

  

跨域请求被阻止:“同源起源”策略禁止读取http://192.168.2.9:5055/webhooks/rest/webhook处的远程资源。 (原因:CORS标头“ Access-Control-Allow-Origin”缺失)

当我尝试访问action_endpoint时,出现上述错误。我正在使用rasa 1.0.6

这是我以前运行的命令     rasa run --cors [“ *”] --endpoints endpoints.yml --debug --enable-api 并采取以下行动:     python3 -m rasa_core_sdk.endpoint --actions操作

在浏览器控制台中,出现错误:

跨域请求被阻止:“同源起源”策略禁止读取http://192.168.2.9:5055/webhooks/rest/webhook处的远程资源。 (原因:CORS标头“ Access-Control-Allow-Origin”缺失)。

在操作结束时,

  

192.168.2.56--[2019-09-17 09:58:44]“选项/ webhooks / rest / webhook HTTP / 1.1” 404 341 2.407519

我使用nginx服务器托管了静态网页。

这是nginx的配置

/ etc / nginx / sites-available / default     服务器{         监听80 default_server;         听[::]:80 default_server;

    # SSL configuration
    #
    # listen 443 ssl default_server;
    # listen [::]:443 ssl default_server;
    #
    # Note: You should disable gzip for SSL traffic.
    # See: https://bugs.debian.org/773332
    #
    # Read up on ssl_ciphers to ensure a secure configuration.
    # See: https://bugs.debian.org/765782
    #
    # Self signed certs generated by the ssl-cert package
    # Don't use them in a production server!
    #
    # include snippets/snakeoil.conf;

    root /var/www/rasachat/Chat-2;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name _;
    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            #add_header 'Access-Control-Allow-Origin' 'origin-list'
            add_header 'Access-Control-Allow-Origin' '*';
            try_files $uri $uri/ =404;
    }
  }

endpoints.yml

action_endpoint:
url: http://192.168.2.9:5055/webhook

credential.yml

rest:
rasa:
url: "http://192.168.2.9:5002/api"

*。js

 $.ajax({
  url: "http://192.168.2.9:5055/webhooks/rest/webhook",
  contentType: 'application/json; charset=utf-8',
  type:"POST",
  data:
    JSON.stringify({"sender":"Rasa",
    "message":userMsg
  }),
  success: function(results){
      generateMessage(results,'user',INDEXX);
  }
});

我该如何解决?
