带定时器的Web服务 [英] Webservice with a Timer

问题描述

您好，



我有一个问题，希望有人能回答。可以创建一个将数据加载到内存中并使用带有该数据的计时器的Web服务吗？您看到我创建了一个程序，该程序每五秒从一个文件读取一次，并在这五秒钟后显示文件中的数据，但现在我想将其转换为Web服务。这可能吗？如果这是一个愚蠢的问题，我真诚地道歉

Hello,

I have a question I hope someone can answer. It is possible to create a webservice that loads data into memory and use a timer with that data? You see I created a program that reads from a file every five seconds and displays the data within the file after those five seconds but now I want to turn this into a webservice. Is this possible? If this is a stupid question I sincerely apologise

推荐答案

是的，这是可以实现的，你可以创建一个Web服务，从文件中读取数据并存储在变量/模型中。

- timer_tick方法将执行代码来读取文件内容并将内容存储在静态变量中。

- 调用Web服务方法时，返回静态变量的内容。



注意，Web服务不是这是编写计时器代码的好地方。如果每5秒执行一次代码，最好的办法是使用带有定时器执行代码5s的Windows服务（读取文件）;文件的内容可以保存在数据存储（SQL Server）中，Web服务只读取数据存储中的最新数据。

Hi,

Yes this is achievable, you could create a web service that reads the data from the file and stores in variable(s)/Model.
- The timer_tick method would execute code to read the file contents and store the contents in a static variable.
- When the web service method is is invoked, you return the contents of the static variable.

Note, the web service isn't a good place to code a timer. If there's code to execute every 5 seconds, your best bet is to go with a Windows service with a Timer executing your code 5s(Read the file); the contents of the file can be saved in a Data store(SQL Server) and the Web service would just read the latest data from the Data Store.
