No response from Ajax call in 07-api-embedded-app

[tobiasblasberg]

Hi,

unfortunately I couldn't manage to install example 07-api-embedded-app.

Setup: Webserver: Nginx that runs locally on a Docker container with provided index.html. Shinyproxy runs on AWS EC2 instance (based on tutorial 1 without authentication).

What works:

• Shiny Apps accessible as usual
• Webpage ob webserver accessible and first ajax call is executed (without response)
• Similar POST API call with postman works fine with correct response

  POST /api/proxy/SOMESPEC/1.1
  Host: MY_MACHINE_IP:8080
  Accept: */*
  Referer: http://localhost/
  User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36
  Content-Type: application/json
  Cache-Control: no-cache
  Postman-Token: abcd...

  What is not working: When entering correct IP and spec (as in example or in working API call), shinyproxy log shows:

  
  2020-07-01 20:11:14.667  INFO 1510 --- [  XNIO-2 task-1] io.undertow.servlet                      : Initializing Spring FrameworkServlet 'dispatch                                         erServlet'

In contrast to the (I guess) correct output when using postman: 

2020-07-01 20:14:56.132 INFO 1510 --- [ XNIO-2 task-9] c.s.docker.client.DefaultDockerClient : Starting container with Id: 3ff2d441946057bd13c77b99a923810a7bdac95e1cd692c45b9a5dfdb2149346 2020-07-01 20:14:59.059 WARN 1510 --- [ XNIO-2 task-9] e.o.shinyproxy.ShinyProxyTestStrategy : Container unresponsive, trying again (2/30): http://localhost:20000 2020-07-01 20:15:01.062 WARN 1510 --- [ XNIO-2 task-9] e.o.shinyproxy.ShinyProxyTestStrategy : Container unresponsive, trying again (3/30): http://localhost:20000 2020-07-01 20:15:03.444 INFO 1510 --- [ XNIO-2 task-9] e.o.containerproxy.service.ProxyService : Proxy activated [user: KAIs5bL3BcBRFYLuEZhP_zDmb5zQBDZ2pNWLLtLG] [spec: SOMESPEC] [id: 477a6719-1e13-4ddd-9082-ddb9c5545082]

I have same issue. Inspecting browser, I get Cross-Origin-Request Blocked. That means proxy-launch request doesn't reach shinyproxy.

Did you find a way of dealing with this?

Hi

The example mentioned in this issue was removed, because there are now better ways to embed a ShinyProxy app, see: https://github.com/openanalytics/shinyproxy-config-examples/tree/master/08-embedded-app

Feel free to open a new issue if you experience any problem with this new demo.
