第一步：在Nuget上安装"Microsoft.AspNet.WebApi.Cors"包，并对api controller使用[EnableCors]特性以及Microsoft.AspNetCore.Authentication.JwtBearer包
第二步：创建.netcore API项目 /控制器：AuthenticateController
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Cors;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Options;
using Microsoft.IdentityModel.Tokens;
using static JSON_WEB_Token.Helper;
namespace JSON_WEB_Token.Controllers
{ //跨域标签
[EnableCors("anyPolicy")]
//API接口打上Authorize标签
[Authorize]
[ApiController]
//路由配置
[Route("api/[controller]/[action]")]
public class AuthenticateController : ControllerBase
{
private JwtSettingsModel _jwtSettings;
public AuthenticateController(IOptions<JwtSettingsModel> jwtSetting)
{
_jwtSettings = jwtSetting.Value;
}
[HttpPost]
public IActionResult Token([FromBody]PasswordModel request)
{
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_jwtSettings.SecetKey));
string userId = request.UserName == null ? request.UserName : request.UserNo;
if (request.UserName != "test" && request.PassWord != "123" )
{
return BadRequest();
}
var tokenModel = Helper.GetAccessTokenModel
(new UserData()
{
UserGid = strUserGid,
UserNo = "test"
},
24 * 365
);
return Ok(tokenModel);
}
}
public class PasswordModel
{
public string UserName { get; set; }
public string PassWord { get; set; }
public string UserNo { get; set; }
public string ClientSecret { get; set; }
}
}
第三步： Helper
using Microsoft.Extensions.Configuration;
using Microsoft.IdentityModel.Tokens;
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.IdentityModel.Tokens.Jwt;
using System.IO;
using System.Linq;
using System.Security.Claims;
using System.Text;
using System.Threading.Tasks;
namespace JSON_WEB_Token
{
public class Helper
{
public static AccessTokenResponse GetAccessTokenModel(UserData userData, int hours = 24, DateTime? expireTimeSpan = null)
{
JwtSettingsModel _jwtSettings = GetAppsettings<JwtSettingsModel>("JwtSettings");
//创建claim
var claim = new Claim[]{
new Claim(ClaimTypes.Sid,userData.UserGid.ToString()),
new Claim(ClaimTypes.Name,userData.UserNo),
new Claim(ClaimTypes.Role,TokenRoleType.UserApp),
};
//对称秘钥 签名秘钥
var key = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(_jwtSettings.SecetKey));
//签名证书(秘钥，加密算法)
var creds = new SigningCredentials(key, SecurityAlgorithms.HmacSha256);
//生成token
DateTime expiresDate = expireTimeSpan ?? System.DateTime.Now.AddHours(hours);
var token = new JwtSecurityToken(_jwtSettings.Issuer, _jwtSettings.Audience, claim, DateTime.Now, expiresDate, creds);
//保存token
var accessTokenModel = new AccessTokenResponse();
accessTokenModel.TokenType = "Bearer";
accessTokenModel.UserNo = userData.UserNo;
accessTokenModel.ExpiresDate = DateTimeToTimestamp(expiresDate);
accessTokenModel.AccessToken = new JwtSecurityTokenHandler().WriteToken(token);
return accessTokenModel;
}
public static long DateTimeToTimestamp(DateTime dateTime)
{
var start = new DateTime(1970, 1, 1, 0, 0, 0, dateTime.Kind);
return Convert.ToInt64((dateTime - start).TotalSeconds);
}
public class UserData
{
public Guid UserGid { get; set; }
public string UserNo { get; set; }
[Required]
public string UserName { get; set; }
public string PassWord { get; set; }
}
public class AccessTokenResponse
{
public string TokenType { get; set; } = "Bearer";
public string UserNo { get; set; }
public string AccessToken { get; set; }
public long ExpiresDate { get; set; }
public Guid ShopGid { get; set; }
public string ShopName { get; set; }
public Guid UserGid { get; set; }
}
/// <summary>
/// 获取配置文件信息
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="setKey"></param>
/// <returns></returns>
public static T GetAppsettings<T>(string setKey)
{
var builder = new Microsoft.Extensions.Configuration.ConfigurationBuilder()
.SetBasePath(Directory.GetCurrentDirectory())
.AddJsonFile("appsettings.json").Build();
return builder.GetSection(setKey).Get<T>();
}
/// <summary>
/// Token用户类型
/// </summary>
public class TokenRoleType
{
/// <summary>
/// 匿名Token
/// </summary>
public const string GuoWaiApp = "国外渠道";
/// <summary>
/// 用户Token
/// </summary>
public const string UserApp = "国内渠道";
}
}
}
第四：JwtSettingsModel
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
namespace JSON_WEB_Token
{
public class JwtSettingsModel
{
//token是谁颁发的
public string Issuer { get; set; }
//token可以给哪些客户端使用
public string Audience { get; set; }
//加密的key 必须是16个字符以上，要大于128个字节
public string SecetKey { get; set; }
}
public class AccessTokenErrModel
{
public string AppId { get; set; }
public string errcode { get; set; }
public string errmsg { get; set; }
public Guid UserGid { get; set; }
}
}
第五：appsettings
{
"Logging": {
"LogLevel": {
"Default": "Information",
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"AllowedHosts": "*",
"JwtSettings": {
"Issuer": "http://localhost:44305",
"Audience": "http://localhost:44305",
"SecetKey": "HelloWorldHelloWorldHelloWorld"
}
}
第六：Startup
using System;

using Microsoft.AspNetCore.Authentication.JwtBearer;
using Microsoft.AspNetCore.Builder;

//options.SaveToken = true;
//options.RequireHttpsMetadata = false;
//主要是jwt token参数设置

ValidAudience = jwtSettings.Audience,
//这里的key要进行加密
IssuerSigningKey = new SymmetricSecurityKey(Encoding.UTF8.GetBytes(jwtSettings.SecetKey))
};
});
#endregion
#region 注册跨域请求服务 CORS 中间件处理跨域请求

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{

else
{
