save messages in the console log to a class

问题

我有两个名为Issues和Requestmessages的类。我使用Visual Studio和.NET Core以及Swagger构建了一个简单的API。我包括了获取、添加和推送方法。我想要能够在每次使用获取、添加和推送方法时向RequestMessage类添加信息。

  1. using System.ComponentModel.DataAnnotations;
  3. namespace APIExample.Models
  4. {
  5.     public class Issues
  6.     {
  7.         public int Id { get; set; }
  8.         [Required]
  9.         public string Title { get; set; }
  10.         [Required]
  11.         public string Description { get; set; }
  12.         public Priority Priority { get; set; }
  13.         public IssueType IssueType { get; set; }
  14.         public DateTime Created { get; set; }
  15.         public DateTime? Completed { get; set; }
  16.     }
  18.     public enum Priority
  19.     {
  20.         Low, Medium, High
  21.     }
  22.     public enum IssueType
  23.     {
  24.         Feature, Bug, Documentation
  25.     }
  26. }
  1. using Microsoft.EntityFrameworkCore;
  2. using System.ComponentModel.DataAnnotations;
  4. namespace APIExample
  5. {
  6.     [Keyless]
  7.     public class RequestMessage
  8.     {
  9.         [Required]
  10.         public string Message { get; set; }
  11.         public DateTime Received { get; set; }
  12.         [Required]
  13.         public string Uri { get; set; }
  14.     }
  15. }
  1. namespace APIExample
  2. {
  3.     public class RequestMessageLogger: IRequestMessageLogger
  4.     {
  5.         private readonly AppDbContext _dbContext;
  6.         private readonly IHttpContextAccessor _httpContextAccessor;
  8.         public RequestMessageLogger(AppDbContext dbContext, IHttpContextAccessor httpContextAccessor)
  9.         {
  10.             _dbContext = dbContext;
  11.             _httpContextAccessor = httpContextAccessor;
  12.         }
  13.         public string bodyAsString;
  14.         public void LogRequest()
  15.         {
  16.             
  17.             if (_httpContextAccessor.HttpContext.Request.Body.CanSeek)
  18.            {
  19.                 string bodyAsString;
  20.                  RewindStream();
  21.                 
  22.                 using StreamReader reader = new StreamReader(_httpContextAccessor.HttpContext.Request.Body, Encoding.UTF8, true, 1024, true);
  23.                 bodyAsString = reader.ReadToEnd();
  25.                 RewindStream();
  26.            }
  28.             var uri = _httpContextAccessor.HttpContext.Request.GetDisplayUrl();
  30.             _dbContext.requestMessages.Add(new RequestMessage { Message = bodyAsString, Received = DateTime.Now, Uri = uri });
  31.             
  32.             _dbContext.SaveChanges();
  33.         }
  35.         private void RewindStream() => _httpContextAccessor.HttpContext.Request.Body.Position = 0;
  36.     }
  37. }

这是我使用的程序类。

  1. using APIExample;
  2. using Microsoft.AspNetCore.Hosting;
  3. using Microsoft.AspNetCore.Http;
  4. using Microsoft.AspNetCore.HttpLogging;
  5. using Microsoft.EntityFrameworkCore;
  7. var builder = WebApplication.CreateBuilder(args);
  9. // 将服务添加到容器中。
  11. builder.Services.AddControllers();
  12. // 了解有关配置Swagger/OpenAPI的更多信息：https://aka.ms/aspnetcore/swashbuckle
  13. builder.Services.AddEndpointsApiExplorer();
  14. builder.Services.AddSwaggerGen();
  15. builder.Services.AddDbContext<AppDbContext>(o => o.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnectioin")));
  17. builder.Services.AddHttpLogging(logging =>
  18. {
  19.     logging.LoggingFields = HttpLoggingFields.All;
  20.     logging.RequestHeaders.Add("sec-ch-ua");
  21.     logging.ResponseHeaders.Add("MyResponseHeader");
  22.     logging.MediaTypeOptions.AddText("application/javascript");
  23.     logging.RequestBodyLogLimit = 4096;
  24.     logging.ResponseBodyLogLimit = 4096;
  25.     
  26. });
  28. var app = builder.Build();
  30. // 配置HTTP请求管道。
  31. if (app.Environment.IsDevelopment())
  32. {
  33.     app.UseSwagger();
  34.     app.UseSwaggerUI();
  35. }
  37. app.UseStaticFiles();
  38. //app.UseMiddleware<RequestMessageLogger>();
  39. app.UseHttpLogging();
  40. app.Use(async (context, next) =>
  41. {
  42.     context.Response.Headers["MyResponseHeader"] =
  43.         new string[] { "My Response Header Value" };
  45.     await next();
  46. });
  48. app.UseHttpsRedirection();
  50. app.UseAuthorization();
  52. app.MapControllers();
  54. app.Run();

英文:

I have a two classes called Issues and Requestmessages. I build simple api using Visual studio and .NET Core and swagger. I included get put and push method. I want to be able to add information to the RequestMessage class everytime the get, put and push methods are used.

  1. using System.ComponentModel.DataAnnotations;
  3. namespace APIExample.Models
  4. {
  5.     public class Issues
  6.     {
  7.         public int Id { get; set; }
  8.         [Required]
  9.         public string Title { get; set; }
  10.         [Required]
  11.         public string Description { get; set; }
  12.         public Priority Priority { get; set; }
  13.         public IssueType IssueType { get; set; }
  14.         public DateTime Created { get; set; }
  15.         public DateTime? Completed { get; set; }
  16.     }
  18.     public enum Priority
  19.     {
  20.         Low, Medium, High
  21.     }
  22.     public enum IssueType
  23.     {
  24.         Feature, Bug, Documentation
  25.     }
  26. }
  1. using Microsoft.EntityFrameworkCore;
  2. using System.ComponentModel.DataAnnotations;
  4. namespace APIExample
  5. {
  6.     [Keyless]
  7.     public class RequestMessage
  8.     {
  9.         [Required]
  10.         public string Message { get; set; }
  11.         public DateTime Received { get; set; }
  12.         [Required]
  13.         public string Uri { get; set; }
  14.     }
  15. }
  1. namespace APIExample
  2. {
  3.     public class RequestMessageLogger: IRequestMessageLogger
  4.     {
  5.         private readonly AppDbContext _dbContext;
  6.         private readonly IHttpContextAccessor _httpContextAccessor;
  8.         public RequestMessageLogger(AppDbContext dbContext, IHttpContextAccessor httpContextAccessor)
  9.         {
  10.             _dbContext = dbContext;
  11.             _httpContextAccessor = httpContextAccessor;
  12.         }
  13.         public string bodyAsString;
  14.         public void LogRequest()
  15.         {
  16.             
  17.             if (_httpContextAccessor.HttpContext.Request.Body.CanSeek)
  18.            {
  19.                 string bodyAsString;
  20.                  RewindStream();
  21.                 
  22.                 using StreamReader reader = new StreamReader(_httpContextAccessor.HttpContext.Request.Body, Encoding.UTF8, true, 1024, true);
  23.                 bodyAsString = reader.ReadToEnd();
  25.                 RewindStream();
  26.            }
  28.             var uri = _httpContextAccessor.HttpContext.Request.GetDisplayUrl();
  30.             _dbContext.requestMessages.Add(new RequestMessage { Message = bodyAsString, Received = DateTime.Now, Uri = uri });
  31.             
  32.             _dbContext.SaveChanges();
  33.         }
  35.         private void RewindStream() =&gt; _httpContextAccessor.HttpContext.Request.Body.Position = 0;
  36.     }
  37. }

Here is the program class that I used.

  1. using APIExample;
  2. using Microsoft.AspNetCore.Hosting;
  3. using Microsoft.AspNetCore.Http;
  4. using Microsoft.AspNetCore.HttpLogging;
  5. using Microsoft.EntityFrameworkCore;
  7. var builder = WebApplication.CreateBuilder(args);
  9. // Add services to the container.
  11. builder.Services.AddControllers();
  12. // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
  13. builder.Services.AddEndpointsApiExplorer();
  14. builder.Services.AddSwaggerGen();
  15. builder.Services.AddDbContext&lt;AppDbContext&gt;(o =&gt; o.UseSqlServer(builder.Configuration.GetConnectionString(&quot;DefaultConnectioin&quot;)));
  18. builder.Services.AddHttpLogging(logging =&gt;
  19. {
  20.     logging.LoggingFields = HttpLoggingFields.All;
  21.     logging.RequestHeaders.Add(&quot;sec-ch-ua&quot;);
  22.     logging.ResponseHeaders.Add(&quot;MyResponseHeader&quot;);
  23.     logging.MediaTypeOptions.AddText(&quot;application/javascript&quot;);
  24.     logging.RequestBodyLogLimit = 4096;
  25.     logging.ResponseBodyLogLimit = 4096;
  26.     
  27. });
  31. var app = builder.Build();
  36. // Configure the HTTP request pipeline.
  37. if (app.Environment.IsDevelopment())
  38. {
  39.     app.UseSwagger();
  40.     app.UseSwaggerUI();
  41. }
  43. app.UseStaticFiles();
  44. //app.UseMiddleware&lt;RequestMessageLogger&gt;();
  45. app.UseHttpLogging();
  46. app.Use(async (context, next) =&gt;
  47. {
  48.     context.Response.Headers[&quot;MyResponseHeader&quot;] =
  49.         new string[] { &quot;My Response Header Value&quot; };
  51.     await next();
  52. });
  54. app.UseHttpsRedirection();
  57. app.UseAuthorization();
  59. app.MapControllers();
  61. app.Run();

得分: 1

我无法在 program.cs 文件中找到对 IHttpContextAccessor 的依赖注入。

尝试添加以下代码：

  1. builder.Services.AddDbContext<AppDbContext>(o => o.UseSqlServer(builder.Configuration.GetConnectionString("DefaultConnection")));
  2. // 为 IHttpContextAccessor 添加依赖注入
  3. builder.Services.AddHttpContextAccessor();
  4. // 或者使用 builder.Services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();

这里 是参考链接。

英文:

I cannot see dependency injection for IHttpContextAccessor in the program.cs file.

Try adding the below code:

  1. builder.Services.AddDbContext&lt;AppDbContext&gt;(o =&gt; o.UseSqlServer(builder.Configuration.GetConnectionString(&quot;DefaultConnectioin&quot;)));
  2. //DI for IHttpContextAccessor
  3. builder.Services.AddHttpContextAccessor();
  4. //Or builder.Services.AddSingleton&lt;IHttpContextAccessor, HttpContextAccessor&gt;();

Here is the reference.
