How to config a HTTP Request Method GET with JSON BODY in JMeter?

I'm facing the issue while writing the scenario in JMeter. It's API using GET Method and requires JSON BODY.

It's very easy if the method is POST/PUT. But I don't know how to do with method GET. I tried: Add HTTP Header Manager with Content-Type:application/json, but nothing help.

As I know, using BODY with GET request is the not the good way, but the developer team has implemented like that, and it can be worked with curl.

So I would like to know can we config this in JMeter or not? and How?

Thanks in advance.

There is a reported bug in JMeter for this https://bz.apache.org/bugzilla/show_bug.cgi?id=60358 and looks like the fix is on the way. Hopefully this issue would be fixed soon.

In fact sending request body with HTTP GET request is not supported by Apache HttpComponents and hence in JMeter, you should be able to send a GET request with JSON body using JSR223 Sampler and the following code (assumes Groovy language):

import org.apache.http.HttpResponse
import org.apache.http.client.methods.HttpEntityEnclosingRequestBase
import org.apache.http.entity.StringEntity
import org.apache.http.impl.client.CloseableHttpClient
import org.apache.http.impl.client.HttpClientBuilder
import org.apache.http.util.EntityUtils

public  class HttpGetWithBody extends HttpEntityEnclosingRequestBase {
    public final static String METHOD_NAME = "GET";

    @Override
    public String getMethod() {
        return METHOD_NAME;
    }
}

def client = HttpClientBuilder.create().build();
def getRequest = new HttpGetWithBody();
getRequest.setURI(new URL("http://example.com").toURI());
def json = "{\"employees\":[\n" +
        "    {\"firstName\":\"John\", \"lastName\":\"Doe\"},\n" +
        "    {\"firstName\":\"Anna\", \"lastName\":\"Smith\"},\n" +
        "    {\"firstName\":\"Peter\", \"lastName\":\"Jones\"}\n" +
        "]}";
def body = new StringEntity(json, "application/json", "UTF-8");
getRequest.addHeader("Content-Type", "application/json");
getRequest.setEntity(body);
def response = client.execute(getRequest);
def result = EntityUtils.toString(response.getEntity());
log.info(result);

See Beanshell vs JSR223 vs Java JMeter Scripting: The Performance-Off You've Been Waiting For! article for more information on using JSR223 test elements and groovy language and scripting best practices.
