对Enyim APi的封装代码1：
/// <summary>
/// 获取缓存对象
/// </summary>
/// <typeparam name="T">缓存的对象类型</typeparam>
/// <param name="key">缓存key</param>
/// <param name="generator">缓存对象的委托</param>
/// <param name="expire">过期时间</param>
/// <returns></returns>
public static Task<T> Get<T>(string key, Func<Task<T>> generator, TimeSpan? expire = null)
{
return memcachedClient.GetValueOrCreateAsync(key, GetSeconds(expire), generator);
}
调用代码2：
public async Task<List<UserCreditLevelConfigCacheDTO>> GetListCache() {
var systemParamCacheList = await MemcachedHelper.Get(MemcachedConstConfig.CacheKey_UserCreditLevelConfigList,
() => {
//todo
}, MemcachedConstConfig.DefaultExpireTime);
return systemParamCacheList.MapToList<UserCreditLevelConfigCacheDTO>();
}
调用代码3：
var creditLevelItemList = await _userCreditLevelConfigService.GetListCache();

代码片段3中，调用了代码2，代码2中调用了代码1。

能看下有关使用EnyimMemcachedCore的代码吗？

 – hellotim 5年前

@hellotim: ok。我再完善一下问题详情

 – Code_Song 5年前

@hellotim: 单步的调试都没有什么问题，但是我在收集的错误日志中，发现有这样的异常错误。不知所以

这个问题与 EnyimMemcachedCore 无关，是你的环境无法写控制台日志

dudu，我的项目类型是.netcore api。如何修复支持console log呢？

Code_Song | 园豆：51 (初学一级) | 2019-02-19 20:13

我再看看，目前我的项目部署环境是windows

Code_Song | 园豆：51 (初学一级) | 2019-02-19 20:14

@Code_Song: 程序运行在什么操作系统上？是什么方式运行的（supervisor, docker...）？日志是如何配置的？为什么不使用 Serilog 而是使用控制台日志？

dudu | 园豆：29732 (高人七级) | 2019-02-19 20:16

Windows 的话，控制台日志会被重定向到文件中，建议检查一下 logs 文件夹的权限

dudu | 园豆：29732 (高人七级) | 2019-02-19 20:18

@dudu: 程序运行在windows2008(测试环境)，自宿主方式运行。项目中的日志方式是用的Nlog，并没有去配置成控制台日志，为什么会去写入控制台呢。

Code_Song | 园豆：51 (初学一级) | 2019-02-19 20:20

@dudu: 项目中对日志配置了收集到mysql数据库

Code_Song | 园豆：51 (初学一级) | 2019-02-19 20:21

@Code_Song: 在 web.config 中将 stdoutLogEnabled 设置为 false

dudu | 园豆：29732 (高人七级) | 2019-02-19 20:34

@dudu: 现在.netcore类型的，没有web.config文件呢。
刚刚发现了另外的错误，帮助看看

@Code_Song: 将 EnyimMemcachedCore 升级到最新版可解决这个问题

dudu | 园豆：29732 (高人七级) | 2019-02-19 20:40

@dudu: 好的

Code_Song | 园豆：51 (初学一级) | 2019-02-19 20:41

@dudu: 最新版本的Nuget包，可以和memache1.5版本一起工作吗

Code_Song | 园豆：51 (初学一级) | 2019-02-19 21:32

@Code_Song: 可以，那个问题已经修复

dudu | 园豆：29732 (高人七级) | 2019-02-19 21:38

@dudu: ok，谢谢

@dudu: 这个是我把应用Enyim Memcached包的项目发布到CentOS服务器上之后，看到的错误日志
env.ConfigureNLog("NLog.config");
app.UseEnyimMemcached();
项目的配置是这样的，参考的Demo来的。

Code_Song | 园豆：51 (初学一级) | 2019-02-24 16:26

@Code_Song: 试试禁用控制台日志

dudu | 园豆：29732 (高人七级) | 2019-02-24 16:36

@dudu: 我看Nlog.Config里面，并没有配置Console类型的日志输出呢
为什么输出到控制台，会影响Enyim.Memcache包的程序？

<target xsi:type="File" name="allfile" fileName="${basedir}/logs/nlog-all-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" />
<target xsi:type="File" name="ownFile-web" fileName="${basedir}/logs/nlog-own-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />
<!--收集异常日志到mysql数据库-->
<target xsi:type="Database" name="database" dbProvider="MySql.Data.MySqlClient.MySqlConnection, MySql.Data"

@dudu: 谢谢dudu,我再观察一下看看，这个异常很怪异。再有问题，我把调用和发生的场景提到git上

Code_Song | 园豆：51 (初学一级) | 2019-02-24 17:46

@Code_Song: 控制台日志是默认就启用的，可以在 Program.cs 中添加下面的代码代码移除控制台日志

.ConfigureLogging((context, logging) =>
{ 
    logging.ClearProviders();
});
dudu | 园豆：29732 (高人七级) | 2019-02-24 18:53

@dudu: 好的
