1、监控中间件
public class OuterApiMonitorMiddleware : IMiddleware
{
//private readonly ILogger<OuterApiMonitorMiddleware> _logger;
private readonly IOuterApiLogger _apiLog;
public OuterApiMonitorMiddleware(/*ILogger<OuterApiMonitorMiddleware> logger,*/ IOuterApiLogger apiLog)
{
//_logger = logger;
_apiLog = apiLog;
}
public async Task InvokeAsync(HttpContext context, RequestDelegate next)
{
var path = context.Request.Path.Value ?? string.Empty;
//注意：这里重点，对访问地址是/PRO/INTEGRATION开头的自动记录log
if (!path.StartsWith("/PRO/INTEGRATION", StringComparison.OrdinalIgnoreCase))
{
await next.Invoke(context);
return;
}
await Monitor(context, next, path);
}
/// <summary>
/// 监控接口调用
/// </summary>
private async Task Monitor(HttpContext context, RequestDelegate next, string path)
{
var stopWatch = Stopwatch.StartNew();
var start = DateTime.Now;
DateTime end;
Exception exception = null;
var requestBody = string.Empty;
var responseBody = string.Empty;
try
{
requestBody = await new StreamReader(context.Request.Body).ReadToEndAsync();
context.Request.Body.Position = 0;
var originalResponseBody = context.Response.Body;
try
{
using var swapStream = new MemoryStream();
context.Response.Body = swapStream;
await next(context);
context.Response.Body.Seek(0, SeekOrigin.Begin);
using var s= new StreamReader(context.Response.Body);
responseBody = await s.ReadToEndAsync();
context.Response.Body.Seek(0, SeekOrigin.Begin);
await swapStream.CopyToAsync(originalResponseBody);
}
finally
{
context.Response.Body = originalResponseBody;
}
}
catch (Exception e)
{
exception = e;
}
stopWatch.Stop();
end = DateTime.Now;
await Logger(context, requestBody, responseBody, (long)stopWatch.ElapsedMilliseconds, start, end, exception);
}
/// <summary>
/// 记录日志
/// </summary>
private async Task Logger(HttpContext context, string requestBody, string responseBody, long elapsed, DateTime start, DateTime end, Exception exception)
{
var entry = new ProOuterApiLog
{
Level = Microsoft.Extensions.Logging.LogLevel.Information,
TimeStamp = DateTime.Now,
Ip = context.Request.HttpContext.GetClientUserIp(),
Header = $"{{Authorization:{context.Request.Headers["Authorization"]},Last_Working_Object_Id:{context.Request.Headers["Last_Working_Object_Id"]}}}",
Host = context.Request.Host.ToString(),
Url = context.Request.Path,
QueryString = context.Request.QueryString.ToString(),
RequestBody = requestBody,
ResponseBody = responseBody,
StartTime = start,
EndTime = end,
ElapsedTime = elapsed,
Message = "",
Exception = exception?.ToString() ?? "",
RequestId = context.Request.HttpContext.TraceIdentifier
};
await _apiLog.HttpRequest(entry);
}
}
2、记录日志
public class OuterApiLogger : IOuterApiLogger
{
private readonly ILogger<OuterApiLogger> _logger;
private readonly IWebHostEnvironment _environment;
private readonly IProOuterApiLogDAL _dal;//这个是DAL层，方便写sql
private readonly IHttpContextAccessor _httpContextAccessor;
public OuterApiLogger(ILogger<OuterApiLogger> logger, IWebHostEnvironment environment, IProOuterApiLogDAL dal, IHttpContextAccessor httpContextAccessor)
{
_logger = logger;
_environment = environment;
_dal = dal;
_httpContextAccessor = httpContextAccessor;
}
public async Task HttpRequest(ProOuterApiLog entry)
{
await Insert(entry);
}
public async Task Information(string message)
{
await Insert(new ProOuterApiLog
{
Level = LogLevel.Information,
Message = message,
});
}
public async Task Warning(string message)
{
await Insert(new ProOuterApiLog
{
Level = LogLevel.Warning,
Message = message,
});
}
public async Task Error(string message, Exception exception = null)
{
await Insert(new ProOuterApiLog
{
Level = LogLevel.Error,
Message = message,
Exception = exception?.ToString()
});
}
public async Task Critical(string message)
{
await Insert(new ProOuterApiLog
{
Level = LogLevel.Critical,
Message = message,
});
}
private async Task Insert(ProOuterApiLog entry)
{
var request = _httpContextAccessor.HttpContext?.Request;
var parameters = new List<SugarParameter>
{
new SugarParameter("@level",entry.Level),
new SugarParameter("@timestamp",DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fffffff")),
new SugarParameter("@ip",entry.Ip ?? request.HttpContext.GetClientUserIp() ?? string.Empty),
new SugarParameter("@header",entry.Header ?? string.Empty),
new SugarParameter("@host",entry.Host ?? request.Host.ToString()?? string.Empty),
new SugarParameter("@url",entry.Url ?? request?.Path?? string.Empty),
new SugarParameter("@querystring",entry.QueryString ?? request?.QueryString.ToString() ?? string.Empty),
new SugarParameter("@requestbody",entry.RequestBody ?? string.Empty),
new SugarParameter("@responsebody",entry.ResponseBody ?? string.Empty),
new SugarParameter("@starttime",entry.StartTime.ToString("yyyy-MM-dd HH:mm:ss.fffffff")),
new SugarParameter("@endtime",entry.EndTime.ToString("yyyy-MM-dd HH:mm:ss.fffffff")),
new SugarParameter("@elapsedtime",entry.ElapsedTime),
new SugarParameter("@message",entry.Message ?? string.Empty),
new SugarParameter("@exception",entry.Exception?.ToString() ?? string.Empty),
new SugarParameter("@requestid",_httpContextAccessor.HttpContext.TraceIdentifier ?? string.Empty)
};
try
{
await _dal.ExecuteBySql("INSERT INTO pro_outer_api_log (level,timestamp,ip,header,host,url,querystring,requestbody,responsebody,starttime,endtime,elapsedtime,message,exception,requestid) VALUES(@level,CAST(@timestamp AS timestamp(6)),@ip,@header,@host,@url,@querystring,@requestbody,@responsebody,CAST(@starttime AS timestamp(6)),CAST(@endtime AS timestamp(6)),@elapsedtime,@message,@exception,@requestid)", parameters.ToArray());
}
catch (Exception e)
{
_logger.LogError(e, "记录日志异常");
}
}
}
3、日志表
