Question

我是JMeter的新手，所以要温柔。我有一个简单的测试计划，可以访问登录页面。此时，它甚至没有登录，只是加载页面。问题是在每次运行时，对页面上的一个CSS文件的请求导致：

如果我再次运行测试，则所有其他请求都会成功，但这一个文件每次都会失败。

这是请求数据：

GET https://example.com/mysite/style/bootstrap.min.css
GET data:
Cookie Data:
JSESSIONID=0753E35583DE3C882E88BE4C37FCFB47; BIGipServerdemo-tomcat=654354624.51526.0000

当我在Chrome或Firefox中加载此页面时，所有文件都会加载，包括此CSS文件，没有任何问题。我怎么能修复这个NoHttpResponseException所以这个CSS文件（我假设更多的东西）按预期返回？

Answer 1

此文件可能位于browser cache中，尝试使用clean session并使用浏览器开发人员工具检查请求，并仔细检查文件是否仍然存在。如果不是 - 这是您的应用程序部署的问题。如果是 - 我只能考虑使用View Results Tree监听器和浏览器开发人员工具或外部嗅探器工具（如Wireshark

来比较JMeter和真实浏览器发送的请求

作为一种解决方法，您可以通过将下一行添加到user.properties文件来禁用检查缺少的嵌入资源

    httpsampler.ignore_failed_embedded_resources=true

JMeter重启将需要选择该属性。

Answer 2

您应该选中HTTP_Request＆＃39} Retrieve All Embedded Resources from HTML Files复选框

告诉JMeter解析HTML文件并发送文件中引用的所有图像，Java小程序，JavaScript文件，CSS等的HTTP / HTTPS请求

因此，您不需要为每个CSS（作为浏览器）提出明确请求

Jmeter：443没有回复
