groovy - Jmeter Groovy 在使用 MSAL4J 时报告 NoSuchMethodError: ResourceOwnerPasswordCredentialsGrant

问题描述

我正在尝试使用Microsoft Authentication Library for Java使用用户名和密码重新创建用户身份验证，因为我们需要向许多租户中的新应用程序授予管理员许可。

为此，我在 Groovy 2.4.16 中添加了一个JSR233 采样器，因此我可以创建一个脚本来使用 msal4j。脚本如下所示：

import com.microsoft.aad.msal4j.*;
import com.nimbusds.oauth2.sdk.*;
//import java.util.concurrent.*;

Set<String> scope = Collections.singleton(Arrays.asList("openid","profile","email", "offline_access"));
String username = vars.get("USER");
String password = vars.get("PASSWORD");

//log.info("USER: " + username);
//log.info("PASSWORD: " + password);
log.info("SCOPE: " + scope);
log.info("CLIENT: " + vars.get("CLIENT"));

UserNamePasswordParameters parameters =
     UserNamePasswordParameters
        .builder(scope, username, password.toCharArray())
        .build();

PublicClientApplication pca = 
    PublicClientApplication.builder(vars.get("CLIENT"))
        .authority("https://login.microsoftonline.com/" + vars.get("TENANT"))
        .build();             

IAuthenticationResult result = pca.acquireToken(parameters).join();

但是，在测试采样器时，我收到以下错误：

ERROR o.a.j.JMeter: Uncaught exception in thread Thread[Thread Group 1-1,6,main]

我认为问题可能在于范围的定义：Set<String> scope = Collections.singleton(Arrays.asList("openid","profile","email", "offline_access"));但我并不完全确定。

解决方案

查看您收到错误的类的JavaDoc，我可以看到它需要 2 个字符串作为参数：

ResourceOwnerPasswordCredentialsGrant​(String username, Secret password)    
Creates a new resource owner password credentials grant.

所以很可能你正遭受一种Jar Hell形式的痛苦，所以仔细检查你的依赖库版本，如果不匹配会导致 API 冲突和错误，就像你面临的那样。

另请注意，根据 JMeter 最佳实践，您应该始终使用最新版本的 JMeter ，因此请考虑在下次有机会时升级到JMeter 5.3 （或JMeter 下载页面上提供的任何最新版本）
