我正在尝试使用 ASP .Net Core 和 Application Insights 在中间件中记录请求和响应，但 Application Insights 不记录信息。我的代码：
RequestResponseLoggingMiddleware.cs
public class RequestResponseLoggingMiddleware
{
private readonly RequestDelegate _next;
private readonly ILogger<RequestResponseLoggingMiddleware> _logger;
private readonly RecyclableMemoryStreamManager _recyclableMemoryStreamManager;
public RequestResponseLoggingMiddleware(RequestDelegate next, ILoggerFactory loggerFactory)
{
_next = next;
_logger = loggerFactory.CreateLogger<RequestResponseLoggingMiddleware>();
_recyclableMemoryStreamManager = new RecyclableMemoryStreamManager();
}
public async Task Invoke(HttpContext context)
{
await LogRequest(context);
await LogResponse(context);
}
private async Task LogRequest(HttpContext context)
{
context.Request.EnableBuffering();
await using var requestStream = _recyclableMemoryStreamManager.GetStream();
await context.Request.Body.CopyToAsync(requestStream);
_logger.LogInformation($"Http Request Information:{Environment.NewLine}" +
$"Schema:{context.Request.Scheme} " +
$"Host: {context.Request.Host} " +
$"Path: {context.Request.Path} " +
$"QueryString: {context.Request.QueryString} " +
$"Request Body: {ReadStreamInChunks(requestStream)}");
context.Request.Body.Position = 0;
}
private async Task LogResponse(HttpContext context)
{
var originalBodyStream = context.Response.Body;
await using var responseBody = _recyclableMemoryStreamManager.GetStream();
context.Response.Body = responseBody;
await _next(context);
context.Response.Body.Seek(0, SeekOrigin.Begin);
var text = await new StreamReader(context.Response.Body).ReadToEndAsync();
context.Response.Body.Seek(0, SeekOrigin.Begin);
_logger.LogInformation($"Http Response Information:{Environment.NewLine}" +
$"Schema:{context.Request.Scheme} " +
$"Host: {context.Request.Host} " +
$"Path: {context.Request.Path} " +
$"QueryString: {context.Request.QueryString} " +
$"Response Body: {text}");
await responseBody.CopyToAsync(originalBodyStream);
}
private static string ReadStreamInChunks(Stream stream)
{
const int readChunkBufferLength = 4096;
stream.Seek(0, SeekOrigin.Begin);
using var textWriter = new StringWriter();
using var reader = new StreamReader(stream);
var readChunk = new char[readChunkBufferLength];
int readChunkLength;
do
{
readChunkLength = reader.ReadBlock(readChunk, 0, readChunkBufferLength);
textWriter.Write(readChunk, 0, readChunkLength);
} while (readChunkLength > 0);
return textWriter.ToString();
}
}
appsettings.json
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"ApplicationInsights": {
"LogLevel": {
"Default": "Error"
},
"ConnectionString": "InstrumentationKey=deletedforskingthisquestion;IngestionEndpoint=https://centralus-0.in.applicationinsights.azure.com/"
},
当我检查我的 Application Insights 时，我看到信息日志尚未注册。我想知道我的错误。提前致谢。

看起来像 LogLevel 的问题：
配置说明：错误
"ApplicationInsights": {
"LogLevel": {
"Default": "Error"
}
}
但是在记录时，您正在 LogLevel：LogInformation
私有异步任务日志请求（HttpContext上下文） { context.Request.EnableBuffering();
await using var requestStream = _recyclableMemoryStreamManager.GetStream();
await context.Request.Body.CopyToAsync(requestStream);
_logger.LogInformation($"Http Request Information:{Environment.NewLine}" +
$"Schema:{context.Request.Scheme} " +
$"Host: {context.Request.Host} " +
$"Path: {context.Request.Path} " +
$"QueryString: {context.Request.QueryString} " +
$"Request Body: {ReadStreamInChunks(requestStream)}");
context.Request.Body.Position = 0;
}
Tyring 将 LogLevel 更改为“错误”。
并在启动类中检查以下配置设置：
public partial class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddApplicationInsightsTelemetry("InstrumentationKey");
}
}

您是否将 NLogger Application Insights 包包含到您的项目中？
尝试将其添加到您的项目中： https://www.nuget.org/packages/Microsoft.Extensions.Logging.ApplicationInsights/ (see this for ref.)
您还可以更改 ApplicationInsights 设置中的 LogLevel，因为现在在您的应用程序中，当您登录 Error 级别时，它似乎只收集 Information 级别。您可以尝试将其更改为 Debug，如下所示：
...
"ApplicationInsights": {
"LogLevel": {
"Default": "Debug"
},
...

应用日志过滤，提供程序别名为 ApplicationInsightsLoggerProvider。默认日志级别是信息，但对于提供程序 ApplicationInsights，它被覆盖为 ApplicationInsights 级别
Error要解决此问题，您可以将 "Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
},
"ApplicationInsights": {
"LogLevel": {
"Default": "Error"
}
}
默认的日志级别更改为 Informatio 并将 ApplicationInsights 移至 ApplicationInsights 部分。
Logging这里还有一点，您正在创建一个新的日志条目来记录请求的请求和响应详细信息/正文。因此，您不需要新的日志条目，您可以更新现有请求遥测中的详细信息。您可以参考 this repo 中提到的代码，该代码可以进一步扩展以记录其他详细信息，并且它还提供在记录请求正文期间删除敏感信息的功能（可以扩展为响应正文）。

update table a set (a.codeid_a,a.col2,a.col3...) = (b.codeid_b,b.col2,b.col3...) from tableb b where b.claimsid_b = a.claimsid_a
文件中有 2 个错误：
在“ApplicationInsights”部分，将“默认”：“错误”更改为“默认”：“信息” .
然后将 "ApplicationInsights" 部分放入 Logging 部分。如下图：
