logstash json发布输出 [英] logstash json post output
问题描述
我目前正在尝试使用tcp输入在JavaScript上发布日志到Logstash.
I am current trying to do a JavaScript post to Logstash by using a tcp input.
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
}
}
控制台中的输出

我似乎看不到我的json数据 {"test":hello} 传递到logstash中，logstash.config文件是否可能有问题?请帮助
I cant seem to see my json data {"test" : hello} passing into logstash could there be something wrong with my logstash.config file ? Please help
推荐答案
实际上，它们是以下@@ strong> JavaScript Post 部分中的javascript错误
Actually their is javascript error found in following line @JavaScript Post section
var data = JSON.stringify( {"test":hello} );
var data = JSON.stringify({"test" : hello});
替换为
var data = JSON.stringify({"test":"hello" });
var data = JSON.stringify({"test" : "hello"});
我，双引号被遗漏了
以上更改将为您提供所需的结果
Above changes will give u the required result
我已经按照以下方式进行了测试
I have tested in following way
