params questions

[郑泽楷]

I'm new to ql.io, and I have a question about it. When I using monkey path to preprocess my requests, how can I inject variables to the 'params' property from the callback function argument. Something like this:

exports['patch header'] = function(options) {
  var params = options.params;   // how can I inject variables to this property?
  // do sth
  return options.header;
}

exports['patch body'] = function(options) {
  var params = options.params;   // same question
  // do sth
  return options.body;
}

I also use some way like 'curl --header 'key:value'' send a request to ql.io server, still not in the options.params.

Can anyone tell me how to do that?

founded....The params are in the proto chain of that options.params object....

use this code to print them:

exports['patch header'] = function(options) {

  var params = options.params;

  while(params) {

    console.log(params);

    params = params.__proto__;

  }

  return options.header;

}
