Proxy fails when sending a POST request with data

[mgalante]

When sending a post body, the proxy doesnt work.

for example:

$.ajax({ 
type: 'post',
data: {"someKey": "someValue"}
...
})

doesn't work in what way? there is not enough information here.. can you send a reproduction case, or just more detail (your local-web-server config, details of what exactly is failing)

Ok here is the thing. I create to VM in digital ocean in one i create a post.php file its just

<?php var_dump($_POST)

in the other one i started local-web-server with a rule to forward all the traffic to the other server. If i just make a post o get to post.php it works, but if i send something in the post content fails I send the console output.

I ll leave the LAMP server UP so you can try it: http://104.131.40.69/post.php It will be really usefull for me if you can fix this.

Thanks for your work and sorry for my pour description of the problem before. I just was in a hurry in my daytime job.

You have this rule

"rewrite": [
    {
      "from": "/*",
      "to": "http://104.131.40.69/$1"
    }
  ]

so a local url of /yeah will proxy to http://104.131.40.69/yeah.. what is the full local url you are sending the POST request to?

i set up a local web server with this config

{
  "port": 8000,
  "rewrite": [
    {
      "from": "/*",
      "to": "http://104.131.40.69/$1"
    }
  ]
}

if i run this command, it seems to work:

$ curl -i http://localhost:8000/post.php
HTTP/1.1 200 OK
date: Fri, 19 Feb 2016 10:50:36 GMT
server: Apache/2.4.7 (Ubuntu)
x-powered-by: PHP/5.5.9-1ubuntu4.14
content-length: 13
connection: close
content-type: text/html

array(0) {
}

however, this command hangs:

$ curl -i http://localhost:8000/lloyd/post.php -d '{"someKey": "someValue"}'

will look into it..

[75lb]

are you sure the issue is not server side? your PHP script is hanging, do you understand why?

[mgalante]

Its not my php. If you execute the curl directly will work. And i tried it also with a java servlet with the same result.

It happens with any post request with data.

isolated, confirmed, fixed and released in v1.1.1.. thanks for the report, please tell me if you have any more issues :+1:
