Question

I am capturing network traffic on Selenium objects on the HTTP post requests I am making. Although JSON string returned has the request headers, the body(params) of the post message is never captured.

Heres my code,

host = "localhost"
port = "4444"
browser = r"*pifirefox"
sel = selenium(host, port, browser, url)
.
.
.....Submit action
postRequest = sel.captureNetworkTraffic('json')

postRequest has,

[{
  "statusCode":200,
  "method":"POST",
  "url":"http://.................",
  "bytes":97567,
  "start":"2011-12-02T17:42:04.719-0500",
  "end":"2011-12-02T17:42:05.044-0500",
  "timeInMillis":325,
  "requestHeaders":[{
      "name":"Host",
      "value":"......................."
    },{
      "name":"User-Agent",
      "value":"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1"
    },{

    },{

      "value":"ISO-8859-1,utf-8;q=0.7,*;q=0.7"
    },{

    },{
      "name":"Referer",
      "value":"...................."
    },{
      "name":"Cookie",
      "value":"...................."
    },{

      "value":"XMLHttpRequest"
    },{

      "value":"Delta=true"
    },{

    },{
      "name":"Content-Type",
      "value":"application/x-www-form-urlencoded; charset=utf-8"
    },{
      "name":"Content-Length",
      "value":"10734"
    },{
      "name":"Pragma",
      "value":"no-cache"
  }],
  "responseHeaders":[{
      "name":"Date",
      "value":"Fri, 02 Dec 2011 22:42:05 GMT"
    },{
      "name":"Server",
      "value":"Microsoft-IIS/6.0"
    },{
      "name":"Cache-Control",
      "value":"private"
    },{
      "name":"Content-Type",
      "value":"text/plain; charset=utf-8"
    },{
      "name":"Content-Length",
      "value":"97567"
    },{
      "name":"X-Powered-By",
      "value":"ASP.NET"
    },{
      "name":"Via",
      "value":"1.1 (jetty)"
    },{
      "name":"X-AspNet-Version",
      "value":"4.0.30319"
  }]
}]

I am trying to imitate the Post request, but without the body(params), its incomplete. Any suggestions would be greatly appreciated.

Cheers,

You can’t get the request or response body with Selenium – it only captures headers. Try Fiddler2 if you’re running on Windows.
