在.NET5中 使用JWT鉴权授权
1、创建一个单独的WebApi项目用作JWT服务,直接使用主服务创建一个控制器也可
2、安装包
PM> Install-Package System.IdentityModel.Tokens.Jwt
3、JWT授权
在登录接口或其它你想颁发Token的地方编写如下Token生成代码
var claims = new Claim[]
{
new Claim(ClaimTypes.Name, author.Name),
new Claim("Id",author.Id.ToString()),
new Claim("UserName",author.UserName)
};
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("SDMC-CJAS1-SAD-DFSFA-SADHJVF-VF"));
//issuer代表颁发Token的Web应用程序,audience是Token的受理者
var token = new JwtSecurityToken(
issuer: "http://localhost:6060",
audience: "http://localhost:5000",
claims: claims,
notBefore: DateTime.Now,
expires: DateTime.Now.AddHours(1),
signingCredentials: new SigningCredentials(key, SecurityAlgorithms.HmacSha256)
);
var jwtToken = new JwtSecurityTokenHandler().WriteToken(token);
return ApiResultHelper.Success(jwtToken);
4、JWT鉴权
安装包
PM> Install-Package Microsoft.AspNetCore.Authentication.JwtBearer
注册服务到容器中
services.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddJwtBearer(options =>
{
options.TokenValidationParameters = new TokenValidationParameters
{
ValidateIssuerSigningKey = true,
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes("SDMC-CJAS1-SAD-DFSFA-SADHJVF-VF")),
ValidateIssuer = true,
ValidIssuer = "http://localhost:6060",
ValidateAudience = true,
ValidAudience = "http://localhost:5000",
ValidateLifetime = true,
ClockSkew = TimeSpan.FromMinutes(60)
};
});
5、JWT授权鉴权使用
Swagger想要使用鉴权需要注册服务的时候添加以下代码
//丝袜哥使用鉴权组件
c.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
Description = "直接在下框中输入WeBlog {token}(注意两者之间是一个空格)",
Name = "Authorization",
BearerFormat = "JWT",
Scheme = "Bearer"
});
c.AddSecurityRequirement(new OpenApiSecurityRequirement
{
{
new OpenApiSecurityScheme
{
Reference=new OpenApiReference
{
Type=ReferenceType.SecurityScheme,
Id="Bearer"
}
},
new string[] {}
}
});
记得添加用户认证组件到管道中
app.UseAuthentication();
app.UseAuthorization();
最后在需要鉴权的接口或者控制器上使用注解即可
需要鉴权
[Authorize]
不需要鉴权
[AllowAnonymous]
