通过openCPU本地测试R app [英] Test R app via openCPU localy

问题描述

我写了一个R包，现在我想提供一个作为Web应用程序的小型演示.为此，我已经编写了一个index.html文件，并将其保存到<pkgRoot>/inst/www/文件夹中.我还安装了opencpu软件包，当我通过localhost:<portNum>/ocpu/test/"Interface"使用它时，它可以很好地工作，在这里我已经可以看到我的软件包并使用Ajax POST和GET请求，以查看该软件包在做什么.

I wrote an R package and now I want to provide let's say a small demo fronted as a webapplication. For this I already wrote a index.html file which I saved to the <pkgRoot>/inst/www/ folder. I also installed the opencpu package which works fine wehen I use it via the localhost:<portNum>/ocpu/test/ "Interface", where I already can see my Package and use the Ajax POST and GET requests in order to see the package is doing what it's ment to do.

但是现在我陷入了某种困境，即我不知道如何测试我自己的应用程序(index.html)的本地设置. localhost:<portNum>/ocpu/<pkgName>/www/index.html不起作用. 据我了解，opencpu随Apache 2一起提供，因此不需要设置额外的Web服务器吗? 据我所知，当我检查安装软件包的路径时，www文件夹以及index.html似乎正是它们应该的位置.

But now im stuck in a sense that I do not know how to test my own app (index.html) localy. localhost:<portNum>/ocpu/<pkgName>/www/index.html does not work. As I understood it, the opencpu Comes with the Apache 2 and hence ist not neccessary to set up an additional webserver? When I check the path to the installed package the www folder as well as the index.html seem to be exactly were they should be, as far as I understand it.

我是否必须通过

opencpu::install_apps("pkgName")

在R内

?因为如果我尝试执行此操作，似乎无法安装本地应用程序，而只能安装在github上托管的应用程序. ....我只想在本地测试应用程序！

inside R? Becaue if I try to do this, it seems there is no way to install local apps but only apps hosted at github. .... and I just want to test the app localy!

真的很高兴有任何建议

推荐答案

只需使用

opencpu::ocpu_start_app("pkgName")

这应该在R中启动HTTP服务器并启动浏览器.

That should start an HTTP server in R and launch your browser.
