无法在Linux服务器上通过OpenCpu创建临时文件

Question

Today we installed opencpu on Linux server. After that all packages are properly loaded but temporary file is not getting created. If we pass value and converted into json like

-d 'x=10'

It is giving only encrypted URL like : -

http://hostname.server.com:8080/auth-sign-in?appUri=%2Fp%2F5656%2Focpu%2Flibrary%2Fmypack12%2FR%2Fhostname@example.com8080:~$

We refer below URL but gives same output as above

If we work on local machine on windows, it is properly working. It would really help if someone can look into the above issue and suggest resolution or workaround.

Answer 1

You should not be accessing the OpenCPU server via Hostname/p/5656/ocpu (which looks like the rstudio ide built-in proxy) but directly via http://Hostname/ocpu .

It looks like your rstudio proxy server intercepts the api request to redirect to a authentication page.

The OpenCPU server builds on Apache2, you don't need RStudio at all. You can use RStudio to write R code if you like, but the two are completely unrelated.
