SignValidate方式验证

添加Startup

1、在ConfigureServices 添加代码

	 services.AddFramework();
	 //cache缓存
	 services.AddSingleton<IMemoryCache, MemoryCache>();
	 services.AddSingleton<ICacheService, MemoryCacheProvider>(); //内存 缓存
	 //services.AddSingleton<ICacheService, RedisCacheProvider>();  //redis 缓存

2、在Configure添加代码

	 app.UseHTTP();
	 
	 //application
	 app.UseApplication();

添加Application

1、在AppService中添加TokenLoadAppService类

    public class TokenLoadAppService
    {
        private readonly IServiceScopeFactory _serviceProvider; //用IServiceProvider 可能出现被释放无法访问对象情况

        public TokenLoadAppService(IServiceScopeFactory serviceProvider)
        {
            _serviceProvider = serviceProvider; 
        }

        public void Init()
        {
            SignValidateAttribute.OnGetToken += GetToken;
        }
        public Token GetToken(string tenant)
        {
            try
            {
                //根据tenant 获取对应 Key
                //用停车场id 在parking表中 获取 key字段
               using (var scope = _serviceProvider.CreateScope()) //不加域 部分项目 可能报错 Cannot access a disposed context instance. 
                {
                    var service = scope.ServiceProvider.GetService<IRepository>();
                    var park = service.FirstOrDefault<Parking>(s => s.Id == tenant);
                    if (park == null) return null;

                    return new Token
                    {
                        ExpireTime = DateTime.Now.AddDays(1),
                        SignToken = park.Key,
                        TenantId = park.Id
                    };
                }
            }
            catch (Exception ex)
            {
                _logger.LogError("获取停车场信息报错", ex);
                throw ex;
            }
        }
    }

2、在AppService下添加 ApplicationExtensions 类

    public static class ApplicationExtensions
    {
        public static IApplicationBuilder UseApplication(this IApplicationBuilder app)
        {
            app.ApplicationServices.GetService<ITokenLoadAppService>().Init();

            //或者
            SignValidateAttribute.OnGetToken += (s =>
            {
                var sub = app.ApplicationServices.CreateScope().ServiceProvider.GetService<IParkingService>().GetByIdAsync(s);
                return new Token { ExpireTime = DateTime.Now.AddDays(1), TenantId = s, SignToken = sub.Result.Data.Key };
            });
            return app;
        }
    }

调用

    [HttpPost]
    [SignValidate]
    public ApiResult CommitEntryRecord([FromBody] CarRecordDto value)
    {
        //接口处理
    }

FixedSignValidate 方式验证

添加Startup

1、在ConfigureServices 添加代码

	 services.AddFramework();

2、在Configure添加代码

	 app.UseHTTP();

使用

    [HttpPost]
    [FixedSignValidate("Signature", "TokenKey", true)]
    public ApiResult CommitEntryRecord([FromBody] CarRecordDto value)
    {
        //接口处理
    }

说明

//Signature 需要验证sign字段名
//TokenKey 密钥
[FixedSignValidate("Signature", "123456789012431243123")]

//Signature 需要验证sign字段名
//TokenKey 密钥 或配置密钥配置项名称
//true key将作为config配置名称，读取配置，false key直接作为密钥参数
[FixedSignValidate("Signature", "TokenKey", true)]

//多级密钥情况填写 
[FixedSignValidate("Signature", "Token:ArrearsTokenKey", true)]

配置

"TokenKey":  "123456789012431243123"

"Token":{
    "ArrearsTokenKey":  "123456789012431243123"
}

第三方调用

   var raw = KeyValueConverter.ToKeyValuePairString(input);
            var token = new Md5Validator(_option.Key).ComputeHashFromString(raw);
            _logger.LogInformation($"Token:{token}，拼接结果：{raw}");
            input.Signature = token;

           return  await _http.PostAsync<ApiResult>("http://opentest.yun-kai.com/", "msparking/recovery/Arrears/Notification", input);

SingVerification 验证

添加Startup

1、在ConfigureServices 添加代码

	 services.AddHTTP();

2、在Configure添加代码

	 app.UseHTTP();

使用

    private readonly SingVerification _sign;

    public HttpTestController(SingVerification sign)
    {
        _sign = sign;
    }

    [HttpPost]
    public async Task<string> Pay()
    {
        var success= _sign.Verification("key密钥"); 
    }

第三方调用

    var raw = KeyValueConverter.ToKeyValuePairString(input);
    var token = new Md5Validator(_option.Key).ComputeHashFromString(raw);
    _logger.LogInformation($"Token:{token}，拼接结果：{raw}");
    input.Signature = token;

    return  await _http.PostAsync<ApiResult>("http://opentest.yun-kai.com/", "msparking/recovery/Arrears/Notification", input);
