中的.NET 6 HttpLogging RequestBody在日志中始终为空

Question

我使用HttpLogging来记录到达我的端点的请求。我想记录整个请求。我在Program.cs 中设置了HttpLogging

builder.Services.AddHttpLogging(logging =>
{
logging.LoggingFields = HttpLoggingFields.All;
});
var app = builder.Build();
// Configure the HTTP request pipeline.
app.UseHttpLogging();

并更改appsettings中的日志记录级别。开发.json

"Microsoft.AspNetCore": "Information"

然后，当我从Postman或cURL发送请求时，我可以看到所有需要的信息，但RequestBody是ALWAYS空的(靠近日志末尾(

info: Microsoft.AspNetCore.HttpLogging.HttpLoggingMiddleware[1]

Request finished HTTP/1.1 POST https://localhost:7269/WeatherForecast application/json 60 - 200 - application/json;+charset=utf-8 19.0485ms

然而，我知道主体在那里，因为当我试图读取控制器中的主体并在断点处停止时，我可以看到变量中加载的主体。

using var reader = new StreamReader(HttpContext.Request.Body);
var myBody = await reader.ReadToEndAsync(); // {"username": "josef","password": "MyPassword"}

有一个从PostMan生成的请求cURL示例。

curl --location --request POST 'https://localhost:7269/WeatherForecast' 
--header 'Content-Type: application/json' 
--data-raw '{
"username": "josef",
"password": "MyPassword"
}'

我不知道是不是有一步我错过了或者类似的事情。我尝试更改不同的日志级别、不同的请求类型、正文和正文类型。RequestBody在日志中始终为空。

我刚刚发现，当我在控制器中保留上面的body读取器并从中读取时，它实际上在日志中记录了正确的RequestBody。有人能解释这种行为吗？我不明白为什么只有当我手动读取正文时，它才会记录。

Answer 1

我已经完成了这项工作(所有这些都与Serilog有关(。我在代码中添加了以下内容：

1. 注册日志设置：

   services.AddHttpLogging(logging =>
   {
   logging.LoggingFields = HttpLoggingFields.All;
   logging.RequestHeaders.Add(HeaderNames.Accept);
   logging.RequestHeaders.Add(HeaderNames.ContentType);
   logging.RequestHeaders.Add(HeaderNames.ContentDisposition);
   logging.RequestHeaders.Add(HeaderNames.ContentEncoding);
   logging.RequestHeaders.Add(HeaderNames.ContentLength);
   logging.MediaTypeOptions.AddText("application/json");
   logging.RequestBodyLogLimit = 4096;
   logging.ResponseBodyLogLimit = 4096;
   });
   

2. 包括一些appsettings.json:

"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft.AspNetCore": "Information",
"Microsoft.AspNetCore.HttpLogging.HttpLoggingMiddleware": "Information"
}
},

可能只需要应用程序设置，尽管如果你想要一个记录的请求表单提交，你肯定需要编码logging.MediaTypeOptions.AddText("multipart/form-data");
