如何在JMeter中使用JSON BODY配置HTTP请求方法GET? [英] How to config a HTTP Request Method GET with JSON BODY in JMeter?

问题描述

在JMeter中编写脚本时遇到了问题.它是使用GET方法的API，并且需要JSON BODY.

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

如果方法是POST/PUT，则非常简单.但是我不知道如何使用GET方法.我尝试过:用Content-Type:application/json添加HTTP Header Manager，但是没有帮助.

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.

据我所知，将BODY与GET请求一起使用不是一种好方法，但是开发人员团队已经实现了这种方法，并且可以与curl一起使用.

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.

所以我想知道我们是否可以在JMeter中进行配置?以及如何?

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

谢谢.

推荐答案

JSR223采样器和以下代码(假设 Groovy 语言):

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);
