本文主要是说明core怎么使用链路追踪
一.添加nuget包
二.在Startup中添加配置
???????/// <summary> ???????/// 注册zipkinTrace ???????/// </summary> ???????/// <param name="app"></param> ???????/// <param name="loggerFactory"></param> ???????/// <param name="lifetime"></param> ???????public void RegisterZipkinTrace(IApplicationBuilder app, ILoggerFactory loggerFactory, IApplicationLifetime lifetime) ???????{ ???????????lifetime.ApplicationStarted.Register(() => ???????????{ ???????????????TraceManager.SamplingRate = 1.0f;//记录数据密度，1.0代表全部记录 ???????????????var logger = new TracingLogger(loggerFactory, "zipkin4net");//内存数据 ???????????????var httpSender = new HttpZipkinSender("http://120.78.146.192:9411", "application/json"); ???????????????var tracer = new ZipkinTracer(httpSender, new JSONSpanSerializer());//注册zipkin ???????????????TraceManager.RegisterTracer(tracer);//注册 ???????????????TraceManager.Start(logger);//放到内存中的数据 ???????????????//File.AppendAllText("D:" + this.GetType().Name + ".txt", DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss" + logger)); ???????????}); ???????????lifetime.ApplicationStopped.Register(() => TraceManager.Stop()); ???????????app.UseTracing("net_core_api");//这边的名字可自定义 ???????}然后在Configure中添加RegisterZipkinTrace(app, loggerFactory, lifetime)注册
三.如何获取spanId和traceId的值
var myTraceId = ConvertHelper.EncodeLongToLowerHexString(Trace.Current.CurrentSpan.TraceId);var mySpanId = ConvertHelper.EncodeLongToLowerHexString(Trace.Current.CurrentSpan.SpanId);
获取出来的值不是真正的spanId和traceId，还需要进行编码：
???????public static string EncodeLongToLowerHexString(long value) ???????{ ???????????return value.ToString("x16"); ???????}好了，现在通过这个方法就可以获取出真正的spanid和traceid，然后输出在日志 以便进行查询日志
注:通过配置以后，只要是请求接口 都会记录下来
菜鸟代码，大神勿喷 如有不对的地方，欢迎指正
