JMeter：采样器结果中的 "Response code: 500, Response message: Internal Server Error"

Question

我正在动态提取我的 asp.net 网站的所有动态值，但是，我可以在采样器结果中看到 "Response code: 500, Response message: Internal Server Error"。

以下是在树中查看结果的请求：

POST http://MyURL/MyPortal/login.aspx

            <h2> <i>Runtime Error</i> </h2></span>

            <font face="Arial, Helvetica, Geneva, SunSans-Regular, sans-serif ">

            <b> Description: </b>An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
            <br><br>

            <b>Details:</b> To enable the details of this specific error message to be viewable on remote machines, please create a &lt;customErrors&gt; tag within a &quot;web.config&quot; configuration file located in the root directory of the current web application. This &lt;customErrors&gt; tag should then have its &quot;mode&quot; attribute set to &quot;Off&quot;.<br><br>

            <table width=100% bgcolor="#ffffcc">
               <tr>

            <b>Notes:</b> The current error page you are seeing can be replaced by a custom error page by modifying the &quot;defaultRedirect&quot; attribute of the application&#39;s &lt;customErrors&gt; configuration tag to point to a custom error page URL.<br><br>

            <table width=100% bgcolor="#ffffcc">

        &lt;customErrors mode=&quot;RemoteOnly&quot; defaultRedirect=&quot;mycustompage.htm&quot;/&gt;

                  </td>
               </tr>

Answer 1

您是否关联了 VIEWSTATE 和 EVENTVALIDATION 参数？如果不是 - 你不能对它们进行硬编码。您需要按如下方式设计测试用例：

GET 登录页面请求（用户打开登录页面）
- 将 "VIEWSTATE"、"EVENTVALIDATION" 和任何其他动态参数提取到 JMeter 变量中
POST 请求登录页面（用户输入凭据）
- 提供先前提取的 "VIEWSTATE" 和 "EVENTVALIDATION" 变量值、登录名、密码和任何其他参数。

根据您的技能和响应的性质，您可以使用以下 Post 处理器来提取动态值：

Regular Expression Extractor (also read Regular Expressions章)
CSS/JQuery Extractor
XPath Extractor
