8-26接口压力测试-3Jmeter-Java请求

1.新建maven工程

2.导入依赖，并使用shade将所需的依赖打入jar包

3.编写Java类

import io.restassured.response.Response;
import org.apache.jmeter.config.Arguments;
import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient;
import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;
import org.apache.jmeter.samplers.SampleResult;

import static io.restassured.RestAssured.given;

public class TestJmeterDemo extends AbstractJavaSamplerClient {
    String corpid;
    String corpsecret;
    @Override
    public void setupTest(JavaSamplerContext context){
        System.out.println("测试开始");
        corpid = context.getParameter("corpid");
        corpsecret = context.getParameter("corpsecret");
    }
    @Override
    public SampleResult runTest(JavaSamplerContext javaSamplerContext) {
        SampleResult result = new SampleResult();
        result.sampleStart();
        //同@Test
        String url = "https://qyapi.weixin.qq.com/cgi-bin/gettoken";

        Response res = given().param("corpid",corpid).param("corpsecret",corpsecret).get(url).prettyPeek();

        String accessToken = res.getBody().jsonPath().getString("access_token");
        if(res.statusCode() == 200){
            result.setSuccessful(true);
            result.setResponseData(res.getBody().prettyPrint(),"UTF-8");
        }else{
            result.setSuccessful(false);
        }
        result.sampleEnd();
        return result;
    }
    @Override
    public void teardownTest(JavaSamplerContext context){
        System.out.println("测试结束");
    }
    /**
     * 参数化
     */
    @Override
    public Arguments getDefaultParameters() {
        Arguments arguments = new Arguments();
        arguments.addArgument("corpid","corpid.value");//value可以为空
        arguments.addArgument("corpsecret","");
        return arguments;
    }
}

4.打包

#打包
mvn clean package
#将打出的jar移到指定目录
mv com.csj2018-1.0-SNAPSHOT.jar ~/otherApp/apache-jmeter-3.3/lib/ext/

5.启动jmeter，添加java请求，运行

问题

1.打的jar包提示某些类不存在，如Uncaught Exception java.lang.NoClassDefFoundError: org/ccil/cowan/tagsoup/Parser. See log file for details.

原因：如果是三方依赖的包，那需要打在最后的jar里，百度搜索assembly的maven。只需要在inclueds里加入这个包即可

                        <configuration>
                            <artifactSet>
                                <includes>
                                    <include>io.rest-assured</include>
                                    <inclued>org.ccil.cowan.tagsoup</inclued><!--缺失的jar包-->
                                </includes>
                            </artifactSet>
                        </configuration>
