通过rsconnect部署管道工API(未找到处理程序) [英] Deploying plumber API via rsconnect (Handler not found)

问题描述

我有一个带有示例API函数(testAPI.R)的目录:

I have a directory with a example API function (testAPI.R):

#* @get /mean
normalMean <- function(samples=10){
 library(plumber)
 data <- rnorm(samples)
 mean(data)
}

rsconnect::deployAPI()函数希望指向包含名为plumber.R的文件的目录，该文件返回plumb对象.所以我在目录中的文件plumber.R为:

The rsconnect::deployAPI() function wants to point to a directory with a file named plumber.R that returns a plumb object. So I have the file plumber.R in the directory as:

library(plumber)
plumber::plumb("testAPI.R")

然后在目录上调用rsconnect::deployAPI() ...

And then calling rsconnect::deployAPI() on the directory...

它部署没有错误，但是似乎没有找到处理程序: 招摇页面的截图

It deploys with no errors but seems to have not found the handler: screenshot of the swagger page

推荐答案

抱歉，我们这里仍然缺少好的文档.当前，这仅在部署到RStudio Connect服务器时才能很好地运行.希望这就是您所使用的.

We're still lacking good docs here, sorry. This will currently only work well when deploying to an RStudio Connect server; hopefully that's what you're using.

内部，RStudio Connect使用plumber::plumb(dir=___)函数来调用您的API.您可以在此处看到文档

Internally, RStudio Connect uses the plumber::plumb(dir=___) function to invoke your API. You can see the docs there

包含plumber.R文件的目录，该文件要解析为plumber路由器定义.另外，如果找到entrypoint.R文件，它将具有优先权并负责返回可运行的Plumber路由器.

The directory containing the plumber.R file to parse as the plumber router definition. Alternatively, if an entrypoint.R file is found, it will take precedence and be responsible for returning a runnable Plumber router.

所以您应该...

1. 将您的主路由器重命名为plumber.R，在这种情况下，RStudio Connect将在执行API时找到并调用该文件.或者
2. 创建一个entrypoint.R文件，该文件将返回您的主路由器.这种方法允许您在路由器上进行一些额外的自定义(或获取其他文件).如果您将其指定为entrypoint.R文件而不是plumber.R文件，则看起来您提供的代码片段实际上可以正常工作.

1. Rename your primary router to plumber.R, in which case RStudio Connect would find and invoke that file when it goes to execute your API. Or
2. Create an entrypoint.R file which returns your primary router. This approach allows you to do some extra customization on your router (or plumb a different file). It looks like the code snippet you provided would actually work if you specify it as the entrypoint.R file instead of the plumber.R file.
