Net5 WorkService 继承 Quarzt
高1234 人气:0Net5 版本以Core为底层非framework框架的windowservice 服务。
在VS里叫WorkService 可以以CMD方式运行也可以以Windowservice方式运行，部署简单。
Program.cs如下，是关键配置和启动项
using Microsoft.Extensions.Hosting;
using Quartz;
using WorkerService.Common;
using WorkerService.Job;
namespace WorkerService
{
public class Program
{
public static void Main(string[] args)
{
CreateHostBuilder(args).Build().Run();
}
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args).UseWindowsService()
.ConfigureServices((hostContext, services) =>
{
#region 原生work Service
//自定义调度
//services.AddHostedService<Worker>();
#endregion
#region quartz 原始版本
//这个版本 trigger job Schedule 是唯一关联，不能一个组下多个任务
//services.AddQuartz(q =>
//{
// q.UseMicrosoftDependencyInjectionScopedJobFactory();
// // Create a "key" for the job
// var jobKey = new JobKey("HelloTestJob");
// // Register the job with the DI container
// q.AddJob<HelloTestJob>(opts => opts.WithIdentity(jobKey));
// // Create a trigger for the job
// q.AddTrigger(opts => opts
// .ForJob(jobKey) // link to the HelloWorldJob
// .WithIdentity("HelloTestJob-trigger") // give the trigger a unique name
// .WithCronSchedule("0/1 * * * * ?")); // run every 1 seconds
//});
//services.AddQuartzHostedService(q => q.WaitForJobsToComplete = true);
#region quarzt 优化版本
// // Register the job, loading the schedule from configuration
// q.AddJobAndTrigger<HelloTestJob>(hostContext.Configuration, "0/1 * * * * ?");//每秒运行一次
// q.AddJobAndTrigger<HelloTestJob2>(hostContext.Configuration, "0/1 * * * * ?");
#region 温湿度 SF6 红外图片上传
services.AddQuartz(q =>
{
q.UseMicrosoftDependencyInjectionScopedJobFactory();
//每秒 0/1 * * * * ? 每小时 0 0 * * * ?
// Register the job, loading the schedule from configuration
q.AddJobAndTrigger<TemperatureJob>(hostContext.Configuration, "0 0 * * * ?");
q.AddJobAndTrigger<SF6Job>(hostContext.Configuration, "0 0 * * * ?");
q.AddJobAndTrigger<InfraredJob>(hostContext.Configuration, "0 0 * * * ?");
});
services.AddQuartzHostedService(q => q.WaitForJobsToComplete = true);
});
}
}原始的Host.CreateDefaultBuilder(args) 需要增加 .UseWindowsService() 支持 对windowservice
quarzt 在 NET5的nuget 中叫Quartz.Extensions.Hosting
services.AddHostedService<Worker>(); 是原始的windows定时任务版本
代码如下， 在await Task.Delay(1000, stoppingToken); 设定定时启动的毫秒数就可以了
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using System;
using System.IO;
using System.Threading;
using System.Threading.Tasks;
namespace WorkerService.Job.Test
{
public class Worker : BackgroundService
{
private readonly ILogger<Worker> _logger;
public Worker(ILogger<Worker> logger)
{
_logger = logger;
}
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
while (!stoppingToken.IsCancellationRequested)
{
_logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
FileStream stream = new FileStream(@"d:\aa.txt", FileMode.Create);//fileMode指定是读取还是写入
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine("123456"+ DateTimeOffset.Now);//写入一行，写完后会自动换行
writer.Write("abc");//写完后不会换行
writer.WriteLine("ABC");
writer.Close();//释放内存
stream.Close();//释放内存
await Task.Delay(1000, stoppingToken);
}
}
}
}quartz 原始版本（program.cs代码截图）
在目前这个quartz 3.3.3 版本中好像不能一个Key 下多个Job集成作业。所以每个job需要一个一个注册。推荐使用优化版本
quarzt 优化版本（program.cs代码截图）
对原始版本进行了封装。在每一次调用的时候会注册新的唯一实例。
以下是帮助类
using Microsoft.Extensions.Configuration;
using Quartz;
using System;
namespace WorkerService.Common
{
public static class ServiceCollectionQuartzConfiguratorExtensions
{
public static void AddJobAndTrigger<T>(
this IServiceCollectionQuartzConfigurator quartz,
IConfiguration config, string cronSchedule)
where T : IJob
{
// Use the name of the IJob as the appsettings.json key
string jobName = typeof(T).Name;
// Try and load the schedule from configuration
var configKey = $"Quartz:{jobName}";
//var cronSchedule = config[configKey];
// Some minor validation
if (string.IsNullOrEmpty(cronSchedule))
{
throw new Exception($"No Quartz.NET Cron schedule found for job in configuration at {configKey}");
}
// register the job as before
var jobKey = new JobKey(jobName);
quartz.AddJob<T>(opts => opts.WithIdentity(jobKey));
quartz.AddTrigger(opts => opts
.ForJob(jobKey)
.WithIdentity(jobName + "-trigger")
.WithCronSchedule(cronSchedule)); // use the schedule from configuration
}
}
}以下是Job
using Microsoft.Extensions.Logging;
using Quartz;
using System;
using System.IO;
using System.Threading.Tasks;
namespace WorkerService.Job.Test
{
[DisallowConcurrentExecution]
public class HelloTestJob2 : IJob
{
private readonly ILogger<HelloTestJob2> _logger;
public HelloTestJob2(ILogger<HelloTestJob2> logger)
{
_logger = logger;
}
public Task Execute(IJobExecutionContext context)
{
FileStream stream = new FileStream(@"d:\aa1.txt", FileMode.Create);//fileMode指定是读取还是写入
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine("123456aaa" + DateTimeOffset.Now);//写入一行，写完后会自动换行
writer.Write("abc");//写完后不会换行
writer.WriteLine("ABC");
writer.Close();//释放内存
stream.Close();//释放内存
return Task.CompletedTask;
}
}
}程序会根据Corn 设定的运行时间定期在Task Execute(IJobExecutionContext context)方法内运行
然后就是蛮搞笑的，大伙都不用Net5 吗。写服务上传文件。遇到问题搜索NET5处理文件上传问题，居然都是空白的。 那我就只好自己写解决方案了。
客户端图片上传的HTTPHelper.cs部分代码如下
/// <summary>
/// 上传文件
/// </summary>
/// <param name="url">请求地址</param>
/// <param name="path">文件路径（带文件名）</param>
/// <returns></returns>
public static string HttpPostFile(string url, string path)
{
// 设置参数
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = "POST";string boundary = DateTime.Now.Ticks.ToString("X"); // 随机分隔线
request.ContentType = "multipart/form-data;charset=utf-8;boundary=" + boundary;
byte[] itemBoundaryBytes = Encoding.UTF8.GetBytes("\r\n--" + boundary + "\r\n");
byte[] endBoundaryBytes = Encoding.UTF8.GetBytes("\r\n--" + boundary + "--\r\n");
int pos = path.LastIndexOf("\\");
string fileName = path.Substring(pos + 1);
//请求头部信息
StringBuilder sbHeader = new StringBuilder(string.Format("Content-Disposition:form-data;name=\"file\";filename=\"{0}\"\r\nContent-Type:application/octet-stream\r\n\r\n", fileName));
byte[] postHeaderBytes = Encoding.UTF8.GetBytes(sbHeader.ToString());
StringBuilder builder = new StringBuilder($"Content-Disposition:form-data;name=\"subPath\"\r\n\r\ntmswechat");
byte[] postHeaderBytestwo = Encoding.UTF8.GetBytes(builder.ToString());
FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read);
byte[] bArr = new byte[fs.Length];
fs.Read(bArr, 0, bArr.Length);
fs.Close();
Stream postStream = request.GetRequestStream();
postStream.Write(itemBoundaryBytes, 0, itemBoundaryBytes.Length);
postStream.Write(postHeaderBytes, 0, postHeaderBytes.Length);
postStream.Write(bArr, 0, bArr.Length);
postStream.Write(itemBoundaryBytes, 0, itemBoundaryBytes.Length);
postStream.Write(postHeaderBytestwo, 0, postHeaderBytestwo.Length);
postStream.Write(endBoundaryBytes, 0, endBoundaryBytes.Length);
postStream.Close();
//发送请求并获取相应回应数据
HttpWebResponse response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序才开始向目标网页发送Post请求
Stream instream = response.GetResponseStream();
StreamReader sr = new StreamReader(instream, Encoding.UTF8);
//返回结果网页（html）代码
string content = sr.ReadToEnd();
return content;
}重点是服务端的接收，部分代码如下
try
{
var files = Request.Form.Files;
if (files != null)
{
var file = files[0];
var location = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + $"Image\\" + file.FileName;
if (!Directory.Exists(System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + $"Image\\")) //判断上传文件夹是否存在，若不存在，则创建
{
Directory.CreateDirectory(System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase + $"Image\\"); //创建文件夹
}
using (var stream = new FileStream(location, FileMode.Create))
{
await file.CopyToAsync(stream);
result = 1;
}
}
//using (var reader = new StreamReader(Request.Body))//从身体里读取
//{
// var body = await reader.ReadToEndAsync();
//}
}
catch (Exception e )
{
throw;
}哪怕你用的是文件流上传，不是表单提交。但是你的文件依旧在Request.Form.Files 里！！！！
但你也可以通过Request.body 读到流
//using (var reader = new StreamReader(Request.Body))//从身体里读取
//{
// var body = await reader.ReadToEndAsync();
//}加载全部内容
