title: Need Example of passing Jasper Reports Parameters for REST v2 API using JSON
body: <p>When I look at the documentation for passing parameters to the Jasper Report REST 2 API here: <a href="http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v550/running-report-asynchronously" rel="nofollow">http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v550/running-report-asynchronously</a> I see that I need to have a "parameters" dict.  The example in the link shows the XML which is not all that useful since it's unclear exactly what the equivalent JSON should look like.  The closest I could find is in this link: <a href="http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v56/modifying-report-parameters" rel="nofollow">http://community.jaspersoft.com/documentation/jasperreports-server-web-services-guide/v56/modifying-report-parameters</a>.  Now, I am sending the equivalent of that to the server (and every other permutation I can think of), and I continue to get a "400 Client Error: Bad Request" back.  I could really use an <em>exact</em> example of the python code to generate the required "parameters" parameter for say "my_parameter_1="test_value_1".</p>
  
  <p>Here is my current POST data (with a few params missing for brevity).  I know this is correct since the report works fine if I omit the "parameters" parameter:</p>
  
  <pre><code>    {
        'outputFormat': 'pdf', 
        'parameters': [{'name': 'ReportID', 'value': ['my_value_1']}], 
        'async': 'true', 
        'pages': '', 
        'interactive': 'false'
      }
  </code></pre>
