【问题描述】：

我目前正在尝试使用 tcp 输入向 Logstash 发布 JavaScript。

JavaScript 帖子

 xhr = new XMLHttpRequest();
 var url = "http://localhost:5043";
 xhr.open("POST", url, true);
 xhr.setRequestHeader("Content-type", "application/json");
 var data = JSON.stringify({"test" : hello});
 xhr.send(data);

Logstash 配置文件

input {
    tcp {
        port => 5043
    }
}

filter{
}

output {
  stdout  { 
        codec => rubydebug
    }
}

控制台输出

          "port" => 55867,

}

我似乎看不到我的 json 数据 {"test" : hello} 传递到 logstash 我的 logstash.config 文件是否有问题？请帮忙

我也尝试了以下方法：

input {
http {
port => 5043
}
}

我得到以下错误是浏览器：

XMLHttpRequest 无法加载 http://localhost:5043/。响应预检请求未通过访问控制检查：否 'Access-Control-Allow-Origin' 标头出现在请求的资源。 Origin 'http://test/' 因此不允许访问。

请指导我正确的方向，我需要看什么？我对 ELK 堆栈非常陌生

谢谢

【解决方案1】：

如果您在 tcp 插件中添加 host 会怎样：

input {
    tcp {            
         host => "localhost"
         port => 5043
         mode => "server" <-- change if it's a client
    }
}

或者您应该在您的 ES yml 中按照 ticket 进行以下设置：

http.cors.enabled: true
http.cors.allow-origin: "*"

希望对你有帮助！
