Logger in ASP.NET Core

In Program.cs, we add following code

.ConfigureLogging(logBuilder => { logBuilder.ClearProviders(); // removes all providers from LoggerFactory logBuilder.AddConsole();
logBuilder.AddTraceSource("Information, ActivityTracing"); // Add Trace listener provider })

2. add code in startup.cs with methodd Configure

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) { // other code remove for clarity loggerFactory.AddFile("Logs/mylog-{Date}.txt"); }

3. install package through PackageManager console

Install-Package Serilog.Extensions.Logging.File -Version 2.0.0

wwwroot

• wwwroot folder in the ASP.NET Core project is treated as a web root folder
• Static files can be stored in any folder under the web root and accessed with a relative path to that root

add bootstrap and jquery file

-> wwwroot -> right click -> add file - Client-side Libarary

-  right click on libman.json file and select "Restore Client-Side Libraries" from the context menu

JWTToken - https://jwt.io/introduction

Step 1 :- Generate 
-   `public string GenerateJSONWebToken()
    {
        // when he is validated AD
        var securityKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_config["Jwt:Key"]));
        var credentials = new SigningCredentials(securityKey, SecurityAlgorithms.HmacSha256);
        var claims = new[] {
            new Claim(JwtRegisteredClaimNames.Sub, "sar"),
            new Claim(JwtRegisteredClaimNames.Email, "[email protected]"),
            new Claim("Role", "Admin"),
            new Claim(JwtRegisteredClaimNames.Jti, Guid.NewGuid().ToString())
            };
        var token = new JwtSecurityToken(_config["Jwt:Issuer"],
          _config["Jwt:Issuer"],
          claims,
          expires: DateTime.Now.AddMinutes(120),
          signingCredentials: credentials);

        return new JwtSecurityTokenHandler().WriteToken(token);
    }`


Step 2: Attache the middle ware 
              
       ` services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
       .AddJwtBearer(options =>
       {

           options.TokenValidationParameters = new TokenValidationParameters
           {
               ValidateIssuer = true,
               ValidateAudience = true,
               ValidateLifetime = true,
               ValidateIssuerSigningKey = true,
               ValidIssuer = Configuration["Jwt:Issuer"],
               ValidAudience = Configuration["Jwt:Issuer"],
               IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(Configuration["Jwt:Key"]))
           };
       });`


Step 3: Add data in file appsettings.json

   `"Jwt": {
            "Key": "545454568686869898989",
            "Issuer": "sarveshsoft"
        }`
