从Beanshell Jmeter运行时不包含JSON

Question

We have a CURL command which basically pushes the status of the run to a dashboard. Below is the command with a dummy URL.

The command has to send two information details to the dashboard; info and info which has contents Text is missing and Please check. This curl command when executed from any Linux box is running correctly and the information sent in the JSON is being displayed but when we try to run the same command from Jmeter Beanshell , it is running successfully but the info in the JSON alone is not coming to the dashboard.

String command = "curl -X POST -d \"status=GREEN\" -d 'info={\"error\":[{\"info\":\"Text is missing\"},{\"info\":\"Please check.\"}]}' abc.com/api/run-dashboard/apikey=456655656";
    Process p = Runtime.getRuntime().exec(command);
    p.waitFor();
#to display the output-
    BufferedReader in = new BufferedReader(new InputStreamReader(p.getInputStream()));
    StringBuilder everything = new StringBuilder();
    String line;
    while( (line = in.readLine()) != null) 
    {
      everything.append(line);
    }
    in.close();
    log.info("OUTPUT: " + everything.toString());
    }

We tried adding the additional header -H "Content-Type: application/json" in the beanshell but in vain.

Can someone let us know what is missing in our command which is sent from Beanshell on why JSON data is not being displayed. shold we add any other header details.

1. You might need to provide full path to curl utility like /usr/bin/curl
2. It might be the case your command fails with some error so make sure to handle p.getErrorStream()

3. Be aware that starting from JMeter 3.1 it is recommended to use JSR223 Test Elements and Groovy language for scripting , consider switching to it as Beanshell performance might be a big question mark. Moreover you will be able to convert your Beanshell code into something like:

    def response = "curl -X POST -d \\"status=GREEN\\" -d 'info={\\"error\\":[{\\"info\\":\\"Text is missing\\"},{\\"info\\":\\"Please check.\\"}]}' http://example.com/api/run-dashboard/apikey=456655656".execute().text log.info(response)
