执行jmeter记录脚本时出现无效登录令牌错误。

Question

我是jmeter的新手。我在jmeter中录制了Moodle的脚本。

录制了ScenarioSteps。

1. 访问Moodle应用程序。
2. 用授权用户登录。
3. 点击课程链接。
4. 登出。

测试运行细节。

运行有超过50个用户的记录脚本，这些用户拥有相同的用户证书（因为应用程序支持多用户登录）。

服务器监控团队共享的错误（执行jmeter脚本时）。

Answer 1

在大多数情况下，你不能只是重播录制的脚本，现代的网络应用广泛使用动态参数，即为。客户端状态跟踪 或 安全原因

在Moodle的情况下，您需要通过 登录令牌 和凭证，它可以从登录页面的响应中提取，即使用 CSS选择器提取器
