.net core 读取本地指定目录下的文件

项目需求

asp.net core 读取log目录下的.log文件，.log文件的内容如下：

xxx.log

------------------------------------------begin---------------------------------
写入时间:2018-09-11 17:01:48
userid=1000
golds=10
-------------------------------------------end---------------------------------

一个 begin end 为一组，同一个.log文件里 userid 相同的，取写入时间最大一组值，所需结果如下：

UserID   Golds   RecordDate
 1001     20     2018/9/11 17:10:48

Snai.File.FileOperation  Asp.net core 2.0 网站

项目实现

新建Snai.File解决方案，在解决方案下新建一个名Snai.File.FileOperation Asp.net core 2.0 空网站

把log日志文件拷备到项目下

修改Startup类的ConfigureServices()方法，注册访问本地文件所需的服务，到时在中间件中通过构造函数注入添加到中间件，这样就可以在一个地方控制文件的访问路径（也就是应用程序启动的时候）

public void ConfigureServices(IServiceCollection services)
{
　　services.AddSingleton<IFileProvider>(new PhysicalFileProvider(Directory.GetCurrentDirectory()));
}

新建 Middleware 文件夹，在 Middleware下新建 Entity 文件夹，新建 UserGolds.cs 类，用来保存读取的日志内容，代码如下

namespace Snai.File.FileOperation.Middleware.Entity
{
    public class UserGolds
    {
        public UserGolds()
        {
            RecordDate = new DateTime(1970, 01, 01);
            UserID = 0;
            Golds = 0;
        }

        public DateTime RecordDate { get; set; }
        public int UserID { get; set; }
        public int Golds { get; set; }
    }
}

在 Middleware 下新建 FileProviderMiddleware.cs 中间件类，用于读取 log 下所有日志文件内容，并整理成所需的内容格式，代码如下

namespace Snai.File.FileOperation.Middleware
{
    public class FileProviderMiddleware
    {
        private readonly RequestDelegate _next;
        private readonly IFileProvider _fileProvider;

        public FileProviderMiddleware(RequestDelegate next, IFileProvider fileProvider)
        {
            _next = next;
            _fileProvider = fileProvider;
        }

        public async Task Invoke(HttpContext context)
        {
            var output = new StringBuilder("");

    }
}

上面有两个方法 ResolveFileInfo()和ResolveDirectory()

ResolveFileInfo()  读取目录下所有文件内容，也就是需求所用的方法

ResolveDirectory() 读取目录下所有文件名，是输出目录下所有目录和文件名，不是需求所需但也可以用

修改Startup类的Configure()方法，在app管道中使用文件中间件服务

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
　　if (env.IsDevelopment())
　　{
　　　　app.UseDeveloperExceptionPage();
　　}

　　app.UseFileProvider();
　　
　　app.Run(async (context) =>
　　{
　　　　await context.Response.WriteAsync("Hello World!");
　　});
}

到此所有代码都已编写完成

启动运行项目，得到所需结果，页面结果如下
