阻止访问Redis密钥（ServiceStack）（redis 6379拒绝访问）

我正在尝试使用ServiceStackRedis客户端实现我认为是非常常见的缓存方案，但是我很难找到一个很好的例子。

在ASP.NETMVC应用程序中，我们对外部Web服务进行了相对长时间的运行（按计量），并将结果缓存了一段时间。在高速缓存实现中，希望阻止对该键的其他请求，直到Web服务调用完成为止，以避免其他（昂贵）调用。

那么，实现键级锁定的最佳方法是什么？Redis开箱即用吗？ServiceStack的IRedisClient.AcquireLock是否适合于此，或者如果我们不处理分布式锁，那是否会过大？还是我最好自己自己实施锁，就像这里描述的那样？

提前致谢！

小编典典

Redis是一个非阻塞异步服务器，在释放密钥之前，没有内置的语义可让Redis在客户端连接上进行阻塞。

注意：Redis是一个远程NoSQL数据存储，因此，您实现的涉及Redis的所有锁都将按设计“分布”。ServiceStack的AcquireLock使用redis的原始SETNX 锁定语义来确保只有1个客户端连接具有该锁定，所有其他客户端/连接都将保持阻塞状态，直到使用指数重试退避倍数进行轮询来释放该锁定为止。

为了在不轮询的情况下实现分布式锁，您需要创建一个解决方案，该解决方案结合使用SETNX + redis的发布/订阅支持来通知等待的客户端该锁已被释放。

$.ajax访问RESTful Web Service报错:Unsupported Media Type

最近在项目中，前台页面使用jquery ajax访问后台CXF发布的rest服务，结果遇到了错误"Unsupported Media Type"。

发布的服务java代码如下:

import javax.jws.WebService;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;

@WebService
@Produces({ "application/json" })
public class TrackService {
	@POST
	@Path("/trackInBatch/")
	@Consumes("application/json")
	public Response postTrackInfoInBatch(List<TrackPosition> positions) {
		return retrieve(positions,clientGen,trafficMapLayerId,projectParaLayerId,"0");
	}
}

调用服务的javascript代码如下：

$.ajax({
	url : "/myapp/rest/track/trackInBatch/",async:false,type : "POST",dataType:"json",data:[],error:function(XMLHttpRequest,textStatus,errorThrown){
		alert(errorThrown);
	},success: function(data,textStatus){
		outResponse = data;
	}		
});

调用的服务的时候报错：Unsupported Media Type。通过HttpWatch查看原始的request和response报文，发现返回request报文中的contentType是：application/x-www-form-urlencoded。查看jquery.ajax()的api文档，发现contentType的默认值就是：application/x-www-form-urlencoded。

但是后台发布的rest服务，@Consumes("application/json")要求request报文的contentType必须是application/json。

手动设置contentType之后，发现问题解决。

$.ajax({
	url : "/myapp/rest/track/trackInBatch/",contentType:"application/json",textStatus){
		outResponse = data;
	}		
});

序言

本篇从.Net如何接入Reis开始，直至.Net对Redis的各种操作，为了方便学习与做为文档的查看，我做一遍注释展现，其中会对list的阻塞功能和事务的运用做二个案例，进行记录学习。

Redis官方推荐的.NET驱动类库为Service.Stack.Redis。然而网上对这个类库的中文文档不是很全面与合理，这篇文章主要就对这个类库做注释展现。不足遗漏之处还望见谅，海涵。

.Net使用Redis是非常方便与快捷与简单的，下面就让我展示下吧。

这里有必要说一下，如果你对Redis 中的基本对象数据类型还不了解，建议你看下我的前几篇Redis文章，保证要到病除。点击：我的Redis系列文章

项目中安装下载Service.Stack.Redis类库

右击项目->管理NuGet程序包->在联机中输入Reis就能出现这个类库，然后添加引入就行啦。

1、配置文件

    }

2、配置Redis链接

public class RedisManager
    {
        /// <summary>
        /// redis配置文件信息
        /// </summary>
        private static RedisConfig RedisConfig = RedisConfig.GetConfig();

        private static PooledRedisClientManager prcm;

        /// <summary>
        /// 静态构造方法，初始化链接池管理对象
        /// </summary>
        static RedisManager()
        {
            CreateManager();
        }

        /// <summary>
        /// 创建链接池管理对象
        /// </summary>
        private static void CreateManager()
        {
            string[] WriteServerConStr = SplitString(RedisConfig.WriteServerConStr, ",");
            string[] ReadServerConStr = SplitString(RedisConfig.ReadServerConStr, ",");
            prcm = new PooledRedisClientManager(ReadServerConStr, WriteServerConStr,
                             new RedisClientManagerConfig
                             {
                                 MaxWritePoolSize = RedisConfig.MaxWritePoolSize,
                                 MaxReadPoolSize = RedisConfig.MaxReadPoolSize,
                                 AutoStart = RedisConfig.AutoStart,
                             });
        }

        private static string[] SplitString(string strSource, string split)
        {
            return strSource.Split(split.ToArray());
        }
        /// <summary>
        /// 客户端缓存操作对象
        /// </summary>
        public static IRedisClient GetClient()
        {
            if (prcm == null)
                CreateManager();
            return prcm.GetClient();
        }
    }

3、IRedisClient为操作Redis的接口，是.Net操作Redis的主要类库，这里我们把它接入

/// <summary>
    /// RedisBase类，是redis操作的基类，继承自IDisposable接口，主要用于释放内存
    /// </summary>
    public abstract class RedisBase : IDisposable
    {
        public static IRedisClient Core { get; private set; }
        private bool _disposed = false;
        static RedisBase()
        {
            Core = RedisManager.GetClient();
        }
        protected virtual void Dispose(bool disposing)
        {
            if (!this._disposed)
            {
                if (disposing)
                {
                    Core.Dispose();
                    Core = null;
                }
            }
            this._disposed = true;
        }
        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
        /// <summary>
        /// 保存数据DB文件到硬盘
        /// </summary>
        public void Save()
        {
            Core.Save();
        }
        /// <summary>
        /// 异步保存数据DB文件到硬盘
        /// </summary>
        public void SaveAsync()
        {
            Core.SaveAsync();
        }
    }

ASP.NET Core扩展库ServiceStack.Redis用法介绍

给大家安利一款 ServiceStack.Redis 的 ASP.NET Core 扩展库，它是基于 ServiceStack.Redis.Core 开发的。简单易用，开源免费，使用ASP.NET Core自身提供的DI容器来实现针对服务的注册和消费。直接在程序启动时注册到服务中即可完成全部配置，对于小白用户也可快速上手Redis缓存和Redis分布式缓存。

Install Package

https://www.nuget.org/packages/ServiceStack.Redis.Extension.AspNetCore

Configure

Startup.cs

Single Server

public void ConfigureServices(IServiceCollection services)
{
    services.AddDistributedServiceStackRedisCache(options =>
    {
        // default single server: 127.0.0.1:6379
        // services.AddServiceStackRedisCache();
        
        // customize single server
        services.AddServiceStackRedisCache(options =>{
        	options.SingleServer = "123456@127.0.0.1:6379";
        });
    }
                                                  
    services.AddControllers();
}

Read and write separation

public void ConfigureServices(IServiceCollection services)
{
    services.AddServiceStackRedisCache(options =>
    {
        options.ReadWriteServers = new[]
        {
            "192.168.1.1:6379", "123456@192.168.1.2:6379", "123456@192.168.1.3:6379", "123456@192.168.1.4:6379"
        };
        options.ReadOnlyServers = new[]
        {
            "192.168.1.1:6379", "123456@192.168.1.3:6379"
        };
    });

    services.AddControllers();
}

Load from configuration

public void ConfigureServices(IServiceCollection services)
{
   
services.AddServiceStackRedisCache(Configuration.GetSection("ServiceStackRedisOptions"));

    services.AddControllers();
}

Usage

WeatherForecastController.cs

[ApiController]
[Route("[controller]")]
public class WeatherForecastController : ControllerBase
{
    private static readonly string[] Summaries = new[]
    {
        "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
    };

    private readonly ILogger<WeatherForecastController> _logger;
    private readonly IServiceStackRedisCache _redisCache;

    public WeatherForecastController(ILogger<WeatherForecastController> logger, IServiceStackRedisCache redisCache)
    {
        _logger = logger;
        this._redisCache = redisCache;
    }

    [HttpGet]
    public IEnumerable<WeatherForecast> Get()
    {
        var array = _redisCache.Get<WeatherForecast[]>("WeatherForecast");
        if (array == null)
        {
            var rng = new Random();
            array = Enumerable.Range(1, 5).Select(index => new WeatherForecast
            {
                Date = DateTime.Now.AddDays(index),
                TemperatureC = rng.Next(-20, 55),
                Summary = Summaries[rng.Next(Summaries.Length)]
            }).ToArray();

            // Cache for 30 minutes
            _redisCache.Set("WeatherForecast", array, 60 * 1 * 30);
        }

        return array;
    }
}

c# – ASP.NET vnext和ServiceStack.redis

有没有人让ServiceStack.redis在asp.net vnext中工作？
我将这些依赖项添加到project.json：

"ServiceStack.Common.Signed": "4.0.40","ServiceStack.Interfaces": "4.0.40","ServiceStack.Redis.Signed": "4.0.40","ServiceStack.Text.Signed": "4.0.40"

dnu restore成功安装了软件包,但是当我尝试在Visual Studio Code(OS X)中编译我的代码时,我得到：“找不到类型或命名空间’ServiceStack’……”

来自dnvm列表：

Active Version              Runtime Arch Location             Alias
------ -------              ------- ---- --------             -----
       1.0.0-beta4          mono         ~/.dnx/runtimes
       1.0.0-beta5-11497    mono         ~/.dnx/runtimes

       dnx-mono             mono         ~/.dnx/runtimes

解决方法

这个由这个nuget解决：
