Core 3.1 系列之 Web API 中间件篇 （一）
身份验证（Jwt）中间件使用步骤
添加 NuGet程序包
添加包：Microsoft.AspNetCore.Authentication.JwtBearer
修改 Startup.cs 文件
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme).AddJwtBearer(options =>{options.TokenValidationParameters = new TokenValidationParameters{RequireExpirationTime = true,ValidateIssuer = true,ValidateAudience = true,ValidateLifetime = true,ValidateIssuerSigningKey = true,ClockSkew = TimeSpan.Zero,ValidIssuer = "testIssuer",ValidAudience = "testAudience",IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("2342423fsklfjafjlkj234k23j2kj3jkljdf"))};});
app.UseAuthentication();app.UseAuthorization();
添加生成Token方法
public string GetToken(){var claims = new[] {new Claim(ClaimTypes.Name, "testUser") };var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("2342423fsklfjafjlkj234k23j2kj3jkljdf"));var jwtToken = new JwtSecurityToken(claims: claims,issuer: "testIssuer",audience: "testAudience",expires: DateTime.Now.AddMinutes(5),signingCredentials: new SigningCredentials(key, SecurityAlgorithms.HmacSha256));return new JwtSecurityTokenHandler().WriteToken(jwtToken);}
使用
请求头携带样例
Authorization:Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJodHRwOi8vc2NoZW1hcy54bWxzb2FwLm9yZy93cy8yMDA1LzA1L2lkZW50aXR5L2NsYWltcy9uYW1lIjoidGVzdFVzZXIiLCJleHAiOjE2NTQxNTY4NDcsImlzcyI6InRlc3Q2NjY2NjY2IiwiYXVkIjoidGVzdDIyMjIyMTExMSJ9.xV_ma0Q2qXg9kIzzpk7YhR_UTs5DfnvLuayBsGCGMac
