java - JMeter 从路径参数开头删除正斜杠

Question

我有一个如下所示的端点:www.example.com/example/{resource}。资源参数通常是一个看起来像这样的 uri 字符串:/resource/123，编码如下:%2Fresource%2Fid%2F123。起始正斜杠很重要，端点与数据库中的某些内容直接匹配，因此很重要。

我面临的问题是，在 JMeter 和端点之间的某个位置，起始的正斜杠被删除了。我尝试在本地运行具有端点的应用程序，当我从 PostMan 发出请求时，如下所示:GET www.example.com/example/%2Fresource%2F123，端点会正确解码它。

在 JMeter 中，我从 CSV 文件加载资源，如下所示:

resource
/resource/123
/resource/456
/resource/789

在我的 HTTP 请求配置中，我使用如下资源:/example/${__urlencode(${resource})}。 urlencode 函数似乎没有任何不同。

无论我做什么，当从 JMeter 发出请求时，它都不会按预期工作，因为资源中的起始哈希被删除。我知道如果没有端点，我可以更改端点以添加散列，但我不想专门针对 JMeter 测试更改端点的功能。

有什么想法吗？

这是 csv 选项:

<CSVDataSet guiclass="TestBeanGUI" testclass="CSVDataSet" testname="Resource Ids" enabled="true">
   <stringProp name="delimiter">,</stringProp>
   <stringProp name="fileEncoding"></stringProp>
   <stringProp name="filename">data/resource.csv</stringProp>
   <boolProp name="ignoreFirstLine">true</boolProp>
   <boolProp name="quotedData">false</boolProp>
   <boolProp name="recycle">true</boolProp>
   <stringProp name="shareMode">shareMode.group</stringProp>
   <boolProp name="stopThread">false</boolProp>
   <stringProp name="variableNames">resource</stringProp>
</CSVDataSet>

这是 HTML 请求配置:

<HTTPSamplerProxy guiclass="HttpTestSampleGui" testclass="HTTPSamplerProxy" testname="API Request" enabled="true">

我添加了这个预处理器:

<JSR223PreProcessor guiclass="TestBeanGUI" testclass="JSR223PreProcessor" testname="JSR223 PreProcessor" enabled="true">
  <stringProp name="cacheKey">true</stringProp>
  <stringProp name="filename"></stringProp>
  <stringProp name="parameters"></stringProp>
  <stringProp name="script">vars.put(&quot;resource&quot;, URLEncoder.encode(vars.get(&quot;resource&quot;), &quot;UTF-8&quot;)); </stringProp>
  <stringProp name="scriptLanguage">groovy</stringProp>
</JSR223PreProcessor>

您只需使用一个斜杠作为路径分隔符，而不是双斜杠

文件中有斜杠，因此在路径中删除多余的斜杠:

/example${resource}

如果您想要/必须对值进行 URL 编码，您可以使用 JSR223 PreProcessor 来完成此操作

将其作为子添加到HTTP请求中(因此它会在之前更新值)，代码:

 vars.put("resource", URLEncoder.encode(vars.get("resource"), "UTF-8"));
