Jmeter无法正确发送http请求

Question

在查看结果树中，我看不到任何发出的http请求。相反，它仅在请求正文下显示null。使用邮递员作品进行测试，并使用maven命令运行jmeter也可以。运行指向我的本地服务器的Jmeter也可以。在我的同事电脑上也可以。

但是，如果我使用计算机向远程服务器发出http请求，那么它只会显示空请求。

截屏到远程服务器

截屏到我的本地主机

Answer 1

上周我发生了同样的事情。我通过从“服务器名称或IP”字段中删除任何正斜杠并将它们移至“路径”字段来解决了该问题。 因此，如果将“ www.example.com/foo/”作为服务器名称，则需要将“ / foo /”部分移至路径。

Answer 2

您正在创建无效的HTTP请求，并为发布请求发送空的请求正文

使用此链接，以使用JMeter进行正确的HTTP请求

Answer 3

在ubuntu计算机上安装openjdk 8版本时，JMeter测试失败，并返回空请求。似乎2019年7月31日openjdk中的最新更新打破了在IP字段中使用/的jmeter功能。我想返回旧版本的openjdk 8，但是不可能，所以我安装了openjdk 11.0.2版本（11.0.4的早期版本），然后转发测试集，这些测试集的网址在“服务器名称或IP”中带有斜杠领域。 https://download.java.net/java/GA/jdk11/9/GPL/openjdk-11.0.2_linux-x64_bin.tar.gz。

为此，我为Apache coomunity开了一个问题： https://bz.apache.org/bugzilla/show_bug.cgi?id=63637

Answer 4

查看以下几行：

  

2019-08-05 14：50：13,959错误oajuBeanShellInterpreter：调用bsh方法时出错：eval源文件：${access_token};'' : Attempt to access property on undefined variable or class name 2019-08-05 14:50:13,959 WARN o.a.j.e.BeanShellPostProcessor: Problem in BeanShell script: org.apache.jorphan.util.JMeterException: Error invoking bsh method: eval Sourced file: inline evaluation of: $ {access_token};的内联求值：''：尝试访问未定义变量的属性或班级名称

如果您以编程方式构建请求，则Beanshell测试元素似乎无法正常工作-请仔细查看Beanshell脚本并进行修复。

前进：

1. Since JMeter 3.1 it's recommended to use JSR223 Test Elements和Groovy语言进行脚本编写
2. Don't inline JMeter Functions or Variables into scripts，请改用基于代码的等效项。例如，您应该将${access_token}更改为vars.get("access_token")，其中 vars 是JMeterVariables类实例的简写。请查看Top 8 JMeter Java Classes You Should Be Using with Groovy文章，以获取有关JSR223测试元素中可用的JMeter API速记的更多信息。
